SingleColumnRowMapper & ColumnMapRowMapper examples in Spring

2013-06-01T12:06:00.002-07:00

Spring JDBC includes two default implementations of RowMapper - SingleColumnRowMapper and ColumnMapRowMapper. Below are the sample usages of those row mappers.

There are lots of situations when you just want to select one column or only a selected set of columns in your application and to write custom row mapper implementations for these scenarios doesn't seem right. In these scenarios, we can make use of the spring provided row mapper implementations.

SingleColumnRowMapper

This class implements RowMapper interface. As the name suggests, this class can be used to retrieve a single value from the database as a java.util.List. The list contains the column values one per each row.

In the below code snippet, the type of the result value for each row is specified by the constructor argument. It can also be specified by invoking the setRequiredType(Class<T> requiredType) method.

public List getFirstName(int userID)
{
String sql = "select firstname from users where user_id = " + userID;

SingleColumnRowMapper rowMapper = new SingleColumnRowMapper(String.class);
List firstNameList = (List) getJdbcTemplate().query(sql, rowMapper);

for(String firstName: firstNameList)
    System.out.println(firstName);

return firstNameList;
}

More information on the class and its methods can be found in the below spring javadoc link.
http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/jdbc/core/SingleColumnRowMapper.html

ColumnMapRowMapper

ColumnMapRowMapper class can be used to retrieve more than one column from a database table. This class also implements RowMapper interface.This class creates a java.util.Map for each row, representing all columns as key-value pairs: one entry for each column, with the column name as key.

public List<Map<String, Object>> getUserData(int userID)
{

String sql = "select firstname, lastname, dept from users where userID = ? ";

ColumnMapRowMapper rowMapper = new ColumnMapRowMapper();
List<Map<String, Object>> userDataList = getJdbcTemplate().query(sql, rowMapper, userID);

for(Map<String, Object> map: userDataList){

      System.out.println("FirstName = " + map.get("firstname"));
      System.out.println("LastName = " + map.get("lastname"));
      System.out.println("Department = " + map.get("dept"));

}

return userDataList;

}

More information on the class and its methods can be found in the below spring javadoc link.

PLS-00201: identifier 'CONTENT_SEARCH.SEARCH_WITH_RESULTSETINTERFACE' must be declared

2012-07-26T06:24:00.000-07:00

Recently, we configured our WebCenterContent (UCM) 11g system to use OracleText as the Search Indexing Engine.

After the Collection was successfully rebuilt, the search was throwing the below error. No results were returned, and always got the error "Unable to return results" on the screen.

Consuming External Web Services in UCM11g

2011-09-26T08:22:00.003-07:00

In our project, we were trying to consume external web services from a component in UCM 11g but were unsuccessful for a long time.

The component in 10g to consume web services was working very well but when upgraded to 11g, this component was not working.

In 10g, we bundled the stub classes as a jar and deployed it as part of custom component ($Component/lib). When this component was deployed in 11g, we were getting the below error.

Illegal Argument Exception..............
Interface not visible from class loader.

It was clear from the error that the stub classes are not loaded to the correct class loader.

Finally we achieved it by placing the stub jar in the $DOMAIN_DIR/lib folder where $DOMAIN_DIR is the UCM Domain. Then removed the jar from the component and its class path and restarted and then it started working.

If there is a better solution to the problem, please leave your suggestions as comments.

Content Server won't start with CSDS failing to get initialized in UCM 11g

2011-08-27T11:25:00.000-07:00

Recently I got the below error, because of which my managed server (content server) in UCM 11g was getting started with errors but the application won't come up.

Failed to initialize the application 'CSDS' due to error com.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad byte..

CSDS is the datasource for the DB that UCM connects to. The CSDS datasource configuration and test connection can be done from the Weblogic Server(WLS) console.

The configuration for CSDS that is viewed through the WLS console is stored in the file
cs-ds-jdbc.xml

The file is located in the below path
$MiddlewareHOME/user_projects/domains/YOUR_DOMAIN/config/jdbc/cs-ds-jdbc.xml

The above mentioned error is due to the encrypted password getting corrupted and to resolve it just replace the encrypted password with its corresponding clear text value in the file cs-ds-jdbc.xml

The password is the schema password to connect to the UCM schema.

Then restart the server, it should start without any errors and the application should come up.

Hope this helps someone.

Weblogic server won't start with invalid pad byte error

2011-08-27T10:48:00.000-07:00

Many of us would have faced the below error and weblogic server won't start shortly after either extending a domain or creating a domain or done something related to domain.
weblogic.security.internal.encryption.EncryptionServiceException: com.rsa.jsafe.JSAFE_PaddingException: Could not perform unpadding: invalid pad byte.

I use weblogic 10.3.4. This error occurs when the SerializedSystemIni.dat file gets corrupted. It simply means that the server is unable to decrypt the encrypted passwords because the file that has the hash value to decrypt it - SerializedSystemIni.dat - has got corrupted.

There is nothing to worry though, this error could be resolved easily.

All the encrypted passwords in the file config.xml should be replaced with its corresponding clear text (ordinary text) values and then start the server.

For example if weblogic@123 was your password for the server, then follow the below steps to solve the error.
1) In SecurityConfiguration tag, do the following.

i) Replace
<node-manager-password-encrypted>{3DES}Va1McYXiUPirK77U+SQfMg==</node-manager-password-encrypted>

with

<node-manager-password-encrypted>weblogic@123</node-manager-password-encrypted>

ii) Replace
<credential-encrypted>{3DES}diqufr0TEjlJuLvdnhvtCxEUbxr0yIm8dadNaJRqiefJgGQqcWagiY4tlLX3I3pWa/jpBKeMzyEJgufp/725y1/PXSt0mWOh</credential-encrypted>

with

<credential-encrypted>weblogic@123</credential-encrypted>

2) In the EmbeddedLDAP tag do the following.

Replace

<embedded-ldap>
<name>Your_Domain</name>
<credential-encrypted>{3DES}OVxKttua/KHdFNAxuTypkcPZFAcC8kSHQ4X/ZrhTRLUFLAGocQP0yBT7xX7qijqTBMcMBuXkPq0PC19KDuGy2/fAUXMUGpUn</credential-encrypted>
</embedded-ldap>

with

<embedded-ldap>
<name>Your_Domain</name>
<credential-encrypted>weblogic@123</credential-encrypted>
</embedded-ldap>

Now start your server. It should start without any error.

Note: A word of caution - don't change the order of any of the tags in the config.xml file because if you change it, then you get SchemaValidator error. Just replace the encrypted passwords with its corresponding clear text values.

Hiding Navigation Menus in UCM 11g

2011-07-29T08:13:00.003-07:00

I was facing problem in hiding the menus that were coming by default - Search and Check In in UCM11g. It took a little time to find out the syntax to make the OOTB menus disappear in 11g.

There is a dynamic html named navigation_filter_rset_menu_item which is used for this purpose. This dynamic html is defined in the file "std_nav.idoc". Follow the below steps to hide the default menus in UCM 11g.

1) Create an environment variable in your component's environment.cfg file.
ShowOOTBMenus=false

2) <@dynamicdata CoreMenuItems@>
id, label, linkType, linkData
MY_MENU, MY Custom Menu, cgi, IdcService=CUSTOM_SERVICE
<@end@>

3) <@dynamicdata CoreMenuItemRelationships@>
parentId, id, loadOrder
MENU_A, MY_MENU, 30
<@end@>

4) <@dynamicdata CoreMenuItemsFlags@>
id, flags
NEW_CHECK_IN, isContributor:isShowOOTBMenus
<@end@>

5)<@dynamichtml navigation_filter_rset_menu_item@>
<$include super.navigation_filter_rset_menu_item$>
<$if not tmpDeleteRow$>
<$if not isTrue(#env.ShowOOTBMenus) and flags like "*isShowOOTBMenus*"$>
<$tmpDeleteRow = 1$>
<$endif$>
<$endif$>
<@end@>

This should hide the Check In menu from the top horizontal menu. This is the same process for hiding the left navigation menus and sub menus.

Hope this helps.

Javascript undefined error when using wwStrings in UCM 11g

2011-05-21T00:38:00.000-07:00

A javascript error is thrown in UCM 11g when wwStrings is used in javascript as in 10g like wwStrings["someString"].

This is because in UCM 11g, wwStrings is moved to the namespace idc.string.wwStrings

So the syntax in UCM 11g to access the strings in javascript is lc("someString") .

It took all day long for me to figure out this.

Creating custom menu items in Oracle UCM 11g

2011-05-04T08:40:00.002-07:00

A lot of things have changed in UCM 11g, and there is not much documentation or article on how to make things work as it did in UCM 10g.

One such thing is creating custom menu items in Oracle UCM 11g.

CoreMenutItems and CoreMenuItemRelationships resources are used to introduce menu items. Below is a sample code on how to get it done.

<@dynamicdata CoreMenuItems@>
id, label, linkType, linkData
MY_SEARCH, My Custom Search, cgi, IdcService=CUSTOM_SEARCH_SERVICE
<@end@>

<@dynamicdata CoreMenuItemRelationships@>
parentId, id, loadOrder
MENU_A, MY_SEARCH, 30
<@end@>

Keep checking this space, I will try to bring some more tips on how to achieve
few more things in UCM 11g.

Forcing the user to select an item from ajax suggest box using JQuery

2011-03-15T08:45:00.000-07:00

Suggest boxes (Type Ahead box) are a great way to display a list of data from database or any other resource from a server in a text box.

There might be requirement at times to force the users to select from the items displayed in suggest box list and not allow them to enter anything other than the list displayed.

This can be done easily using JQuery. JQuery has a parameter named mustMatch which should be set to true. By default mustMatch is set to false. Here is an example.

$("#sampleSuggest").autocomplete("Server_URL",
{
minChars: 3,
max: 10,
multiple: true,
multipleSeparator: "\n",
mustMatch: true,
matchContains: true,
scrollHeight: 220,
}

mustMatch saved my day. I hope it saves someone else's day.

Configuring UCM application in Eclipse IDE

2010-11-21T04:50:00.000-08:00

I tried to set up a development environment to create custom Java components for UCM application using Eclipse IDE. There is a step by step procedure available in Bex's book and that should suffice to set up development environment for most people. But somehow I was unable to get it set up and working.

After a lot of trial and error method, I got the Content Server to start from within the IDE. I thought of sharing my experience with those who are new to development of custom Java components.

The following step by step procedure is for UCM 10gR3 and Eclipse version 3.4.2.

First let us create a simple component 'MyFirstComponent' using Component Wizard. Using this component let us change the filename that is displayed to the title entered during check-in.
We can achieve this by writing a filter using validateStandard.

Lets set up the component in Eclipse.

Follow the below steps.
1) Open Eclipse.
2) Windows -> Preferences -> Java Compiler and set it to Java 1.5.
3) File -> New -> Project -> Java Project.
4) Name the project MyFirstComponent and click Next.
5) In the Source tab, click the Browse button which is present at the bottom of the page besides the Default Output Folder text box.
6) In the Folder Selection dialog box, select the project name and click Create New Folder button.
7) In the New Folder dialog box, enter the folder name as classes and click the Advanced>> button.
8) Select the Link to folder in the file system check box. Click browse and browse to the directory ucm/custom/MyFirstComponent/classes. If classes folder is not there, it must be created and then linked.
9) Click OK and set the Default Output Folder to MyFirstComponent/classes.
10) In the Libraries tab, add all the jars needed to be in the class path. Some of the mandatory jars are given below.
ucm/shared/classes/server.zip
ucm/shared/custom/Folders_g/classes.jar
It depends on what all is being used in the components.
11) Click Finish.

Now in the src folder of the project, create a package named myfirstcomponent

Then create the below class file in that package.

package myfirstcomponent;
import intradoc.common.ExecutionContext;
import intradoc.common.ServiceException;
import intradoc.data.DataBinder;
import intradoc.data.DataException;
import intradoc.data.Workspace;
import intradoc.shared.FilterImplementor;

public class MyFilter implements FilterImplementor
{
public int doFilter(Workspace ws, DataBinder binder,
ExecutionContext cxt) throws DataException, ServiceException
{

String title = binder.getLocal("dDocTitle");
String fileName = binder.getLocal("primaryFile");

String newFileName = title + fileName.substring(fileName.lastIndexOf("."));
binder.putLocal("primaryFile",newFileName);

return FilterImplementor.CONTINUE;
}
}

Now build the project, the class file for the above java file, should be created in the path
ucm/custom/MyFirstComponent/classes.

The class file also should be displayed in the classes folder of the proj in Eclipse IDE.

Next configure the above created filter in the component definition file. Open the MyFirstComponent.hda file located in the below location.
ucm/custom/MyFirstComponent/MyFirstComponent.hda

Configure the filters as below.
@ResultSet Filters
4
type
location
parameter
loadOrder
validateStandard
myfirstcomponent.MyFilter
null
1
@end

Select the Project in the Eclipse and click Run Configurations from the Run menu.

Run Configurations dialog box would have opened. Select Java Application from the left menu and click New icon from top.

Give it the name MyServer.
In the Main tab, for the project browse and select our project MyFirstComponent. Then for the Main class enter IdcServer.

In the Arguments tab, in the Working Directory section, select other and enter the below path.
D:\oracle\ucm\server\bin (For you it might be different). You can click FileSystem button and browse and select the directory.

In the Environment tab, click New and enter the following name-value pair
Name : PATH
Value : D:\oracle\ucm\server\shared\os\win32\lib

You can add more libraries, by separating with a semicolon. It purely depends on your project.
Click Apply and Close button.

Now we are all set to start the content server from the IDE. Click Run from the Run menu.

The content server should start in the Eclipse. Now open a browser and type the url for the application. In my case it was http://localhost/idc. Then check-in a file. The filename after check-in should be display the title that was entered during check-in.

To run the in Debug mode, just click Debug from Run menu.

Happy debugging using Eclipse for UCM applications.

Leave your comments if you have any suggestions,corrections or queries. Have a good day..

Folder Move in Oracle UCM (Stellent)

2010-11-06T06:28:00.000-07:00

I would like to share my experience on COLLECTION_MOVE_LOT service of Oracle UCM 10gR3. This is the service which we used for moving folders from one folder to another in our application.

There were few problems when we actually started implementing the move functionality.

First thing is that the folders that were moved and the documents under it did not inherit the metadata values from destination folder. They still retained the same metadata of the source location.

To overcome this issue, a new method was introduced at the end of all methods in COLLECTION_MOVE_LOT service. This new method's purpose is to update the metadata of the moved folders and documents as per the destination collection's metadata. For updation of metadata, we invoked the COLLECTION_UPDATE_META service from this new method.

Let me give an overview of the COLLECTION_UPDATE_META service. The COLLECTION_UPDATE_META service is used to propagate the inheritable metadata of the parent folder to all the child folders and documents under it. The propagation of the metadata to the documents is achieved by invoking the COLLECTION_UPDATE_ALL service from inside the code of the service COLLECTION_UPDATE_META.

So, when the COLLECTION_UPDATE_META service is used along with COLLECTION_MOVE_LOT to propagate the metadata of the destination folder on the folders that got moved, it introduced new problems.

One problem was that although the moved documents' metadata got updated, the web viewable files of all the documents were not physically relocated according to the destination location's account settings. So all the web-viewable files were not accessible after folder move operation. I solved this problem by commenting the code which was invoking the COLLECTION_UPDATE_ALL service and then invoked the UPDATE_DOCINFO service which updates the metadata of the documents plus physically moves the web-viewable files to the correct location.

The other problem was COLLECTION_UPDATE_META service, updates all the folders and documents under a specific folder. But our requirement was to update the metadata of only the folders that got moved and the documents under it. So we had to overwrite the setContentAsCollectionMetadata method which is the method that does the job for the service COLLECTION_UPDATE_META. I just wrote a small logic to propagate the destination folder's metadata only to the folders that got moved and the documents under it.

If you have some inputs, corrections or suggestions on this post, please leave a comment, so that I can improve my application.

Have a good day...

UCM Security - Need To Know component - sample step by step implementation

2010-10-09T06:26:00.000-07:00

Guys,

Recently I came across a requirement which had to restrict the standard UCM Content Server security for few documents. Luckily we found there was already a component provided by Oracle just for that purpose (either to extend or restrict the standard security) named Need To Know.

This component can be downloaded from the Oracle website. Although there was a complete sixty page document for this component, it was no cakewalk for me to get it working. I tried to google but no luck, not much has been written about this component in the internet. So, I thought of writing one and sharing my experience.

The Need to Know component supports customization for Content Security, Search Results, Hit list roles, Content metadata security, and WHERE clause calculation. I will touch upon the Content Security part in this article.

The Need to Know component works on Security Group.

Lets get started with a sample requirement.
Consider a sample UCM application which has three security groups namely "SECGRP1", "SECGRP2" and "CONF_SECGRP". Accounts are enabled (about which we don't bother for this requirement). The requirement is to restrict access to some of the documents belonging to the Security Group "CONF_SECGRP". Even if user "A" has read permission on "CONF_SECGRP" as per standard security, we need to restrict it based upon some query given during check-in or update of the document.

Step 1 - Installation : Install the "Need to Know"(NTK) Component using either Component Manager or Component Wizard. Enable it.

Step 2 - Configuration :
a) Open the Admin Server Page and click the General Configuration link.
b) Under the "Additional Configuration Variables" heading, add the below
entry at the end of the text area.
SpecialAuthGroups=conf_secgrp
Only the security groups specified in the SpecialAuthGroups variable will use
the NTK component. Other security groups will have standard security applied.
c) Add a new metadata field that will be used for content-item level queries
(remember our requirement - restrict users based upon some value).
Add the new metadata field using the Configuration Manager. Use any field
name you wish. Here we name it as "DocDisclosureQuery". The field type
should be "memo". After adding the field, click Update Database Design.
d) Add a hit list role using the User Admin Applet. Create two roles "hitlist-r"
and "hitlist". Give read access to "CONF_SECGRP" for the role hitlist-r and
write access to "CONF_SECGRP" for the role hitlist. Do not assign this role
to any user.
e) Restart the content server.

Step 3 - NTK Administration : In the administration tab, you must be able to see a link for NTK component administration - NTK Configuration Information. Click on that link. NTK Administration screen looks as below.

Now we need to configure the new metadata field and hit list roles that we created in the last step.

a) Configuring the DocDisclosure field :

Click Edit button on the top right corner and select "Content Security Configuration Information" link. Scroll to the bottom of the page, in the
"Other Options" section, select the new metadata field that was created as the Disclosure Field and click Update.

b) Configuring the Hit List Role :

Click Edit button on the top right corner and select "Hit List Roles Configuration Information" link. Select "hitlist-r" role as Query Role and "hitlist" role as Update Role and click Update.

c) Limiting Access :

In the "Content Security Configuration Information" page, under the "Read Options" section, select "Yes" for both "Use Security" and "Limit Access". Since our requirement is to limit read access, we did the above configuration only in the "Read Options" section.

In the "Script" text area, write the below script which will determine the read access, based upon the content-item level query given during check-in or update of the document.

<$if isDisclosureQuery(xDocDisclosureQuery)$>
<$isNTKReadAccess=1$>
<$endif$>

Click Update button.

Now the NTK Configuration Information Page should appear as below reflecting the configurations done till now.

Step 4 : Click the "New Check In" link in the top menu and in the Content Check In form now a new metadata field for DocDisclosureQuery will appear along with a "update" button adjacent besides it.

The DocDisclosureQuery applet will be loaded by clicking the update button adjacent to the DocDisclosureQuery field. This applet will contain all the user attributes which can be used to form a content item level query that determines the access on top of standard security.

Step 5 - Check-in a document :
We are all set to check-in a document, specify a content level query and check whether all this works.

Click "New Check In" link in the menu.
1) Give the title of the document.
2) Select the Security Group - the one that is specified in SpecialAuthGroups.
3) Browse the document.
4) Enter all other metadata as per your application.

5) Content Item Level Query :
Click the Update button adjacent to the DocDisclosureQuery field. In the applet
select the "Field" as "Username", "Operator" as "Is" and Value as should be allowed to view this document>. Click Add button. The query
"Username is selvam" appears in the "Query Expression" text area.
You can form complex queries by making use of different user attributes and the
Add, Update and Merge buttons in the applet. For our example we will stick with
one user attrubute to form the query - Username.

Click Append button. The query should now appear in the DocDisclosureQuery field text area as below. You can even directly edit the query in the DocDisclosureQuery field text area.

Click "Check In". The document is successfully checked in now.

Step 6 - Testing the NTK security :
Login using user "selvam" and try to access the above checked-in document. This user must be able to view the content information page of the document.

Login using any other user who have read access to "CONF_SECGRP" other than "selvam" and try to access the document. "Insufficient Access Privilege" error will be thrown.

This is a very simple example of extending standard UCM security using NTK component.

There is one other thing to be noted here. If in your application, the virtual folders belong to the security group specified in the SpecialAuthGroups, and if the Read Access is limited using NTK component, then users won't be able to view the folders. There will be number of ways to overcome this problem. I did it the following way. There is a filter called "checkExtendedSecurityModelDocAccess". NTK makes use of this filter to extend the standard UCM security. The actual class implementing this filter is "NTKFilter" in the NTK component. So you can override this filter in such a way that the NTK security is not applied for the COLLECTION related services.

Hope this post serves as a good starting point to extend Standard UCM security using NTK component.

Good day..

Autocomplete feature not working in eclipse

2010-09-05T07:21:00.000-07:00

If the auto complete feature is not working in eclipse, then check the below setting in eclipse.

Go to Windows->Preferences->Java->Editor->Content Assist->Advanced and check whether the option "Other Java Proposals(Focused)" is checked or not.

If this option is not ticked, then tick that option. This shall resolve the problem.

Radio Button Functionality in Check boxes

2010-08-27T11:46:00.000-07:00

Sometimes we need to implement the functionality of radio buttons using check boxes. It is very rare, but then...... This is just a very simple example..

<HTML>
<HEAD>
<script language='Javascript'>

function disableCheckbox(form)
{
var count = 0;
var loc = "";
var table = document.getElementById('table1');
var rows = table.getElementsByTagName("tr");
if(form.chks.length)
{
for (var j=0;j<form.chks.length;j++)
{
if (form.chks[j].checked)
{
count = 1;
loc = j;
break;
}
}
if(count == 1)
{
for(var j=0;j<form.chks.length;j++)

UCM Content Server Error

2009-11-21T12:29:00.000-08:00

Sometimes UCM Content Server doesnot start when you attempt to start it. If the error is one of the below, then it is because some other service is already listening on that port. So kill that process and the content server will start sweetly.

Follow my earlier post "How to find the process which is using a port" or do a google search on how to find the process which is already listening on a port.

After you the find the process listening on the port that content server is attempting to listen kill that process and then start the content server.
It should be java.exe.

How to find which process is using a port in Windows

2009-11-21T12:10:00.000-08:00

The netstat command is used to display the TCP/IP network protocol statistics and information.

For help and to find all the options available with netstat command execute the below command.
c:/>netstat /?

To find all the open ports and which process is listening on those ports in Windows 2003 server follow the below steps.

Go to command prompt and type netstat -ano
It gives you the result of all active process running on the system along with the port to which they listen.

Then once you get the process id(PID) from the above step,
Go to Task Manager -> Processes tab.
Click View Menu -> Select Columns..
And select the check box of PID so that it gets displayed on the Processes tab.
Now using the PID got from the first step, get the process name which is listening on a particular port.

Servlet and Jsp Version and Server Information

2009-09-08T12:20:00.000-07:00

Servlet and Jsp Version and also the Server information such as name and version that is being used can be obtained using the follwing code.

package com.servlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.jsp.JspFactory;

public class VersionServlet extends HttpServlet {

protected void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {

PrintWriter out = response.getWriter();

//Servlet Version
//getMajorVersion() -> Returns the major version of the Java Servlet API that this servlet container supports.
//getMinorVersion() -> Returns the minor version of the Servlet API that this servlet container supports.
out.println("Servlet Version " +
this.getServletContext().getMajorVersion() + "." +
this.getServletContext().getMinorVersion());

//Jsp Version
out.println("Jsp Version " +
JspFactory.getDefaultFactory().getEngineInfo().
getSpecificationVersion());

//ServerInformation
//getServerInfo -> Returns the name and version of the servlet container on which the servlet is running.
out.println("Server Info " + this.getServletContext().getServerInfo());

}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}

}

Case Insensitive Replace in Java

2009-07-28T12:33:00.000-07:00

public class TestReplaceAll {
public static void main(String[] args) {
String str = "I am a programMeR";
System.out.println("input : " + str);
str = str.replaceAll("(?i)programmer", "developer");
System.out.println("output : " + str);
}
}

This program might be helpful in replacing words which are not consistent with respect to case in a string. This piece of code was given by a colleague.

Simple Javascript code for validating only numbers in a text box

2009-07-26T12:02:00.000-07:00

A small script which will allow only numbers to be typed inside a textbox.
No other character or symbol will be allowed.
This would be helpful if we have a field in which only numbers should be entered by user.

function validateForNumbers(valFromTextBox)
{
if(valFromTextBox.value.length>0)
{
valFromTextBox.value =
valFromTextBox.value.replace(/[^\d]+/g, '');
}
}

Call this function on "onkeyup" event.
