debug maven project in eclipse

2013-05-19T14:59:00.005+03:00

This post (http://www.homik.de/think/index.php/2008/07/31/debugging-maven-projects-with-eclipse/) explains how to debug a maven project with eclipse ide. i just copy the steps from that post:

Create a new Java Project and call it “Maven Debug”. This Project willnever have any source code in it, it is just a shell for attaching the debugger.
Create a debug configuration: Run -> Debug Configurations and then right click on Remote Java Application and select New launch configuration. Call it “Maven Surefire”.
On the Connect tab click the Browse button and select the “Maven Debug” project.
Set connection properties to localhost and port 5005. This is the port on which Surefire waits for the debugger.
The connection type is Standard (Socket Attach)
On the Source tab add all projects that have any Maven source that you want to debug.

During debugging process:

Select break points in the code you’re are going to run. Note, you cn select only code in your test classes. It won’t work on classes outside the test phase.
In your command line, append the following switch to your maven command: -Dmaven.surefire.debug. For example, to debug the tests run by the maven lifecycle install do mvn install -Dmaven.surefire.debug
Wait for maven to pause its execution and display the message: Listeningfor transport dt_socket at address: 5005
Attach the debugger to the running maven by selecting the “Maven Surefire” debug configuration created above. Your debugger should stop at your breakpoint.

install maven plugin

2013-05-19T09:45:00.001+03:00

I have discovered an API that can be useful to my thesis project. Unfortunately, the API address is broken at the moment. However, i could be able to find source code which is maven project. Therefore, i installed maven in my Eclipse Juno. http://stackoverflow.com/questions/11242107/maven-with-eclipse-juno is helpful for this purpose.

In summary,

Install maven

download http://maven.apache.org/download.cgi#Installation (i used apache-maven-3.0.5-bin.zip)
extract the zip and follow the ReadMe file (which says to add bin folder to PATH environment variable)

In Eclipse IDE, do Help -> Install New Software as follows: (installing maven for eclipse plugin)

After a successful installation, I imported the maven project by doing File -> Import as follows:

However, I got the following error during import process:

However changing maven installation path in Eclipse via Preferences interface did not help to resolve the problem :( So I continued the import process with errors..

EDIT 13:49

The problem was due to my import project style.. I included all the pom files at first, however importing only the pom in the parent directory was enough! That solved the situation in my condition..

dbpedia vs freebase

2013-05-03T14:03:00.004+03:00

For my thesis project, i need a programmatically easy-to-use, powerful dictionary.. Therefore, i made (collected actually) a list of items that compares Freebase (http://www.freebase.com/) and Dbpedia (http://dbpedia.org/About).

Dbpedia in general is more accurate as it directly rips off stuff from Wikipedia. Freebase has a longer tail, since it collects info not just from Wikipedia, but also various other data sources.
Both extract structured data from Wikipedia and make it available as RDF.

Different schemas, identifiers, goals

Dbpedia -> stores its data as RDF tuples
Freebase -> n-tuples
Dbpedia -> data is automatically generated from Wikipedia several times a year
Freebase -> data is automatically imported into Freebase after two weeks
Dbpedia -> query via a SPARQL endpoint
Freebase -> query via an MQL (Metaweb Query Language) API

Differences in

Range of data sources

Dbpedia -> focuses on just Wikipedia data
Freebase -> import data from a wide variety of sources

Ability to edit content

Dbpedia -> requires that you edit Wikipedia for the change to appear in Dbpedia
Freebase -> user-editable, contributions can be made via a public interface

Structure of organizations

Dbpedia -> funded by various organizations
Freebase -> funded by Google

Through the common link of Wikipedia, it is possible to link some Freebase topics to Dbpedia resources.

(in Freebase RDF output OWL:SameAs points to Dbpedia) Example: http://dbpedia.org/page/Tetris

Freebase -> open, Creative Commons licenced, graph database

An entity is a single person, place or thing. Freebase connects entities together as a graph.

Freebase API:

a collection of HTTP API's providing read & write access to data stored in Freebase.
different API's support different use cases.
SEARCH API -> returns Freebase data given a free text user query.
MQL Services (mqlread & mqlwrite) allow performing structured queries on Freebase using MQL. (This is the most common way to access graph data and to ask questions)
TEXT Service -> takes an ID of a topic, returns its description
IMAGE Service -> takes an ID, returns an image
need to obtain an API Key - unique key generated using the console (on Google account, API console, create project)

The project passes key (key=(API_KEY))

Limit -> read quota of 100k per day, write 10k.

for higer quota, do request more on google
quotas on sandbox are more, but sandbox is erased every sunday!
data dumps may be used locally for more limit (the size is 14 GB as i remember)

depends on Google API client libraries

API Services:

Search -> find entities by keyword search
MQL Read -> retrieve detailed structured data about entities or collections of entities
Topic API -> get a summary of all the info for an entity
RDF API -> get a summary of all the info for an entity in RDF
Text Service -> get short textual descriptions for entities
Image Service -> get repr. thumbnails for entities
Freebase Suggest -> UI Widget picking entities

URI pattern for an API call:

GET https://www.googleapis.com/freebase/<version>/<apiname>[<path>]? [<urlparams>]

if request query is too long, params should be passed via POST.

but X-HTTP-Method-Override: GET header must be added to request.

version is v1 for production, v1sandbox for sandbox environment (experimental)

callback -> url param will return a json structure enclosed in a javascript function call as an argument to the function (supports JSONP pattern)

Freebase API Sample Code Generator (http://codify.freebaseapps.com/) -> strongly recommend to try this!

multiple reports in one viewer - telerik reports

2013-05-02T16:33:00.003+03:00

My requirement is to view several reports in one report viewer as follows:

In order to view multiple (4 in this case) reports in one report viewer:

ReportBook rb = new ReportBook();
rb.Reports.Add(new SauOgrisReport());
rb.Reports.Add(new SauOgrisReport());
rb.Reports.Add(new SauOgrisReport());
rb.Reports.Add(new SauOgrisReport());

ReportViewer viewer = (ReportViewer)this.ReportContent.Controls[0];

viewer.Report = rb;

couchdb + django

2013-04-23T17:42:00.000+03:00

http://lethain.com/an-introduction-to-using-couchdb-with-django/ is an excellent tutorial for integrating couchdb with django..
(couchdb version 0.8, django version 1.5 on Windows 7)
In order to succesfully run the example, i did the following:

- if you get the error,
cannot import name ResourceNotFound,
edit couch_docs/view.py as follows:
from couchdb~~.client~~ import ResourceNotFound

- if you get the error,
AssertionError at / The XView middleware requires authentication middleware to be installed. Edit your MIDDLEWARE_CLASSES setting to insert 'django.contrib.auth.middleware.AuthenticationMiddleware'.

do what it says..

- if you get the error,
The Django authentication middleware requires session middleware to be installed. Edit your MIDDLEWARE_CLASSES setting to insert 'django.contrib.sessions.middleware.SessionMiddleware'.

do what it says.. settings.py becomes as follows:

MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.middleware.doc.XViewMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
)

- if you get the error,
Error importing template source loader django.template.loaders.filesystem.load_template_source: "'module' object has no attribute 'load_template_source'"

update settings.py as follows:

TEMPLATE_LOADERS = (
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
# 'django.template.loaders.eggs.Loader',
)

After the above fixes, the example worked for me..

a python book - part 1

2013-04-19T15:26:00.001+03:00

Nowadays, i am trying to learn Python and prepared a repository consisting of Python books, tutors etc..

Actually, finding good documentation on Python isn't that hard due to its widespread use..

Anyway, i am using the online free book on ww.rexx.com/~dkuhlman/ and take my own notes during study..

In this post, i publish those notes of mine as notebook pages, a weird way for sharing actually!!

The book consists of three parts, and (i can say that) this is the summary of first part..

allow postgresql connection without password

2013-03-07T12:09:00.002+02:00

I am trying to run a thesis project on my local environment. In order to achieve this, i installed postgresql (v9.2) and have to connect it with my computer's user name and no password! (it is not possible to change the code in jar file and the configuration file is missing!) To accomplish this:
- i added a login role (by using pgAdmin GUI) with my computer's name and defined it with no password
- i edited pg_hba.conf file as follows:

host all all 127.0.0.1/32 ~~md5~~trust

pictureBox usage (Telerik reports)

2013-02-18T09:43:00.002+02:00

http://www.telerik.com/help/reporting/report-items-picture-box.html explains how to use a pictureBox component pretty well. In my case, the photograph of the user is loaded to the pictureBox component dynamically. In order to accomplish this the first step is reading the photo from the photograph database:

1:  public static MemoryStream connectDbGetPhoto(string queryParam)  
2:      {  
3:        // open a connection to the database  
4:        SqlConnection dbCon = new SqlConnection(ConfigurationManager.ConnectionStrings[SauConstants.PHOTO_DATABASE].ConnectionString);  
5:        try  
6:        {  
7:          dbCon.Open();   
9:          StringBuilder query = new StringBuilder(" SELECT Resim from Resimler WHERE UserId = " + queryParam);  
10:          SqlDataAdapter adapter = new SqlDataAdapter(query.ToString(), dbCon);  
11:          DataSet ds = new DataSet();  
12:          adapter.Fill(ds);  
13:          DataTable dt = new DataTable();  
14:          dt = ds.Tables[0];  
15:          byte[] barrImg = (byte[])dt.Rows[0]["Resim"];  
16:          MemoryStream mstream = new MemoryStream(barrImg);  
17:          return mstream;  
18:        }  
19:        catch (Exception e)  
20:        {  
21:          return null;  
22:        }  
23:        finally  
24:        {  
25:          dbCon.Close();  
26:        }  
27:      }

Then the image is loaded to PictureBox component as follows:

1:  MemoryStream resim = connectDbGetPhoto(user.ID.ToString());  
2:  this.picResim.Value = Image.FromStream(resim);

However, if the loaded photograph is too big for the pictureBox, layout problems arise as in http://www.programmersheaven.com/mb/VBasic/322240/322240/display-whole-picture-in-picture-box-or-formplease-help/ To solve this problem:

1:  this.picResim.Sizing = ImageSizeMode.ScaleProportional;

By the way, i use http://codeformatter.blogspot.com/ for a while to format my source code and i strongly recommend it!!

workaround for error "The version of SQL Server in use does not support datatype 'datetime2' "

2013-02-13T09:35:00.003+02:00

http://stackoverflow.com/questions/316422/using-sql-server-2008-and-sql-server-2005-and-date-time
explains the error pretty well.
In short, the workaround is opening the .edmx file with notepad, searching for phrase ProviderManifestToken and replacing 2008 with 2005..

ProviderManifestToken="2005"

RadGrid: format double with eval

2013-01-11T14:52:00.002+02:00

In order to format double with eval :

 <telerik:GridTemplateColumn HeaderText="Ortalama" DataField="Ortalama" UniqueName="Ortalama"  
                         SortExpression="Ortalama" HeaderStyle-Width="80px" >  
                         <ItemTemplate>  
                           <%# String.Format("{0:f2}", DataBinder.Eval(Container.DataItem, "Ortalama"))%>  
                         </ItemTemplate>  
                       </telerik:GridTemplateColumn>

the solution is from: http://stackoverflow.com/questions/5168592/force-a-string-to-2-decimal-places

RadComboBox: custom sorting of items

2013-01-11T11:18:00.000+02:00

The link (http://www.telerik.com/help/aspnet-ajax/combobox-how-to-implement-custom-sorting.html) explains how to implement a custom sorting mechanism for RadComboBox..
It says that Telerik RadComboBox sorts by using the text by default, but it seems to use the value instead..
In order to sort by text, the following class can be used:

1:  public class RadComboSortByText : IComparer  
2:    {  
3:      public int Compare(object x, object y)  
4:      {  
5:        RadComboBoxItem p1 = new RadComboBoxItem();  
6:        RadComboBoxItem p2 = new RadComboBoxItem();  
7:        if (x is RadComboBoxItem)  
8:          p1 = x as RadComboBoxItem;  
9:        if (y is RadComboBoxItem)  
10:          p2 = y as RadComboBoxItem;  
11:        int cmp = 0;  
12:        if (p1.ComboBoxParent.Sort == RadComboBoxSort.Ascending)  
13:        {  
14:          //here we compare the Text of the items  
15:          cmp = String.Compare(p1.Text, p2.Text, !p1.ComboBoxParent.SortCaseSensitive);  
16:        }  
17:        if (p1.ComboBoxParent.Sort == RadComboBoxSort.Descending)  
18:        {  
19:          //here we compare the Text of the items  
20:          cmp = String.Compare(p1.Text, p2.Text, !p1.ComboBoxParent.SortCaseSensitive) * -1;  
21:        }  
22:        return cmp;  
23:      }  
24:    }

.. and itemBound of RadComboBox:

1:  protected void ComboEgitimDali_ItemDataBound(object sender, RadComboBoxItemEventArgs e)  
2:      {  
3:        ComboEgitimDali.Sort = RadComboBoxSort.Ascending;  
4:        ComboEgitimDali.SortItems(new RadComboSortByText());  
5:      }

 <telerik:RadComboBox ID="ComboEgitimDali" runat="server" OnItemDataBound="ComboEgitimDali_ItemDataBound">

RadGrid: to deselect the last selected item on client side

2013-01-10T11:25:00.000+02:00

In order to deselect the last selected item in the RadGrid, the following function can be used on client side:
javascript:

 <telerik:RadCodeBlock ID="RadCodeBlock" runat="server">  
     <script type="text/javascript">  
       function DeselectLastSelected(gridID, index) {  
         var masterTable = $find(gridID).get_masterTableView();  
         masterTable.deselectItem(masterTable.get_selectedItems()[index].get_element());  
       }  
        function RowSelected(sender, eventArgs) {  
         if (sender != null) {  
           var numOfSelected = sender.get_masterTableView().get_selectedItems().length;  
           DeselectLastSelected(sender.ClientID, numOfSelected - 1);  
         }  
       }  
  </script>  
   </telerik:RadCodeBlock>

RadGrid:

RadGrid: to disable select-all checkbox in header

2013-01-09T13:36:00.000+02:00

In order to disable (or make invisible) the select-all checkbox, the following javascript may be used:
the javascript code:

 <telerik:RadCodeBlock ID="RadCodeBlock" runat="server">  
     <script type="text/javascript">  
       function DisableAllSelectOption(sender, eventArgs) {

RadGrid: coloring a line dynamically on client side

2013-01-08T14:23:00.000+02:00

In a radgrid, changing forecolor of a row dynamically on client side is pretty easy. It can be achieved by using GridTemplateColumn:

 <telerik:GridTemplateColumn HeaderText='Not' HeaderStyle-Width="50px">  
           <ItemTemplate>  
             <div style='color: <%# Eval("Renk")%>'>  
               <%# Eval("OgrenciNihaiNot")%>  
             </div>  
           </ItemTemplate>  
         </telerik:GridTemplateColumn>

using javascript with multiple user controls

2013-01-08T14:15:00.001+02:00

When using the same user control multiple times in the same page, accessing the user controls with javascript may be problematic, since locating a specific user control (i mean to seperate the user controls from each other) is a bit tricky.
In my condition, i solved by using a prefix as follows:

1:  function RowSelectionChanged(sender, eventArgs) {  
2:    if (sender != null) {  
3:      // to access a component in this user control  
4:      var prefix = sender.ClientID.substring(0, sender.ClientID.lastIndexOf("_"));  
5:      var param1= document.getElementById( prefix + '<%= "_LabelParam1" %>').value;  
6:      // to access a component in the main page  
7:      var prefixMainPage = sender.ClientID.substring(0, sender.ClientID.lastIndexOf("MyUserControl"));  
8:      var param2= document.getElementById(prefixAnaSayfa + '<%= "HiddenParam"%>').value;  
9:    }  
10:  }

easy login mechanism for demo purposes

2012-12-26T11:45:00.002+02:00

When you need to prepare a quick demo for a few users and you have not implemented your login mechanism yet, you can easily add forms authentication to you asp.net web application.

a simple login form (.aspx file)

<p>

<asp:Label ID="UserNameLabel" runat="server" AssociatedControlID="UserName">Username:</asp:Label>

<asp:TextBox ID="UserName" runat="server" CssClass="textEntry"></asp:TextBox>

</p>

<p>

<asp:Label ID="PasswordLabel" runat="server" AssociatedControlID="Password">Password:</asp:Label>

<asp:TextBox ID="Password" runat="server" CssClass="passwordEntry" TextMode="Password"></asp:TextBox>

</p>

server side (aspx.cs file):

protected void Page_Load(object sender, EventArgs e)

{

if (FormsAuthentication.Authenticate(this.UserName.Text, this.Password.Text))

{

FormsAuthentication.RedirectFromLoginPage(this.UserName.Text, true);

}

add the following lines to web.config file:

</credentials>

</forms>

</authentication>

</authorization>

Your demo app is secure now.. Demo users can only login with the credentials specified.

how to telerik:RadMenu show path

2012-12-15T16:36:00.002+02:00

In order to view the selected path from your telerik RadMenu as in the picture below, you can use the following code:

aspx code:

<telerik:RadSiteMap ID="BreadCrumbSiteMap" runat="server" DataTextField="Text" DataNavigateUrlField="NavigateUrl">
<DefaultLevelSettings ListLayout-RepeatDirection="Horizontal" SeparatorText="/" Layout="Flow" />
</telerik:RadSiteMap>

csharp code:

protected void Page_Load(object sender, EventArgs e)
{
RadMenuItem currentItem = RadMenu.FindItemByUrl(Request.Url.PathAndQuery);
if (currentItem != null)
{
currentItem.HighlightPath();
DataBindBreadCrumbSiteMap(currentItem);
}
else
RadMenu.Items[0].HighlightPath();
}

private void DataBindBreadCrumbSiteMap(RadMenuItem currentItem)
{
List breadCrumbPath = new List();
while (currentItem != null)
{
breadCrumbPath.Insert(0, currentItem);
currentItem = currentItem.Owner as RadMenuItem;
}
BreadCrumbSiteMap.DataSource = breadCrumbPath;
BreadCrumbSiteMap.DataBind();
}

using Telerik Scheduler to view weekly lesson plan

2012-12-13T14:56:00.000+02:00

In this post, i present the code that configures Telerik radscheduler to view a weekly lesson plan. In order to do this, the selected date attribute should be a month starting at Monday (which is the first week day in the scheduler.)

.aspx code (actually i use it as a user control )

<telerik:RadScheduler runat="server" ID="RadScheduler" Width="750px" SelectedView="WeekView"

TimeZoneOffset="00:00:00" SelectedDate="2013-04-01" DayStartTime="07:00:00" DayEndTime="23:59:00"

ReadOnly="true"

DataEndField="End"

DataKeyField="DersProgramiID" DataStartField="Start" DataSubjectField="DersItem"

AllowDelete="False" AllowEdit="False" AllowInsert="False"

DayView-DayStartTime="07:00:00" DayView-DayEndTime="23:59:00" LastDayOfWeek="Sunday"

WeekView-DayEndTime="23:59:00" WeekView-DayStartTime="07:00:00" WeekView-WorkDayEndTime="23:59:00"

WeekView-WorkDayStartTime="07:00:00" WorkDayEndTime="23:59:00" WorkDayStartTime="07:00:00" FirstDayOfWeek="Monday"

Height="900px" ShowNavigationPane="True" ShowAllDayRow="False" ShowHeader="False" ShowFullTime="False" ShowFooter="False" HoursPanelTimeFormat="HH:mm">

<TimelineView UserSelectable="false" ShowDateHeaders="false"></TimelineView>

<TimeSlotContextMenuSettings EnableDefault="true"></TimeSlotContextMenuSettings>

<AppointmentContextMenuSettings EnableDefault="true"></AppointmentContextMenuSettings>

</telerik:RadScheduler>

csharp code to fill the scheduler:

public void fill(List list)

{

this.RadScheduler.DataSource = list;

this.RadScheduler.DataBind();

}

The weekly lesson plan is as follows:

introduction to telerik reports

2012-10-23T17:02:00.000+03:00

it has been years since i have not dealt with reporting.. so, i am a total newbie for this..
in this post, i share my one-day activity on warming up using telerik reports, a sample telerik report about a specific user's information viewed in a web app and how to deploy it in a remote server..
first thinngs first.. my bookmarks:

http://tv.telerik.com/search?&keywords=reporting -> all videos about telerik reports
http://tv.telerik.com/watch/reporting/webinar/telerik-reporting-101 -> a startup webinar by Kevin Babcock.. the webinar pretty much follows the totorial on http://www.telerik.com/support/documentation-and-tutorials/step-by-step-tutorial-for-reporting.aspx. i recommend to watch the webinar, it is easier to understand..
http://tv.telerik.com/watch/reporting/webinar/falafelreportingwebinar -> another startup webinar.. i have not watched this yet, but i am planning to do so..
http://tv.telerik.com/watch/reporting/video/telerik-trainer-reporting-parameters -> about report parameters. good demos..
http://tv.telerik.com/watch/reporting/sqldatasource/using-parameterized-queries-telerik-reporting-with-sqldatasource-component and http://tv.telerik.com/watch/reporting/video/telerik-reporting-design-time-support-for-parameterized-queries -> these two videos are actually for my specific needs.. producing a report by passing the user id from the hosting web app..

Report library part:

Now, the first step is creating a report library project.. Then a telerik report is created. i used the report wizard and used an SqlDataSource as the data source. My select query contains a parameter:

SELECT ...

FROM ...

WHERE TableStudent.ID = @StudentID

The report also contains a parameter with the same name.

The constructor for the report is something like that:

public ReportStudent(int studentID)

{

InitializeComponent();

this.ReportParameters["StudentID"].Value = studentID;

this.StudentDataSource.Parameters[0].Value = studentID;

this.StudentDataSource.SelectCommand = this.StudentDataSource.SelectCommand.Replace("@StudentID", studentID.ToString());

}

Web app part:

In the web app which is going to view the report, i added a report viewer from the toolbox, but left the report property unassigned. In the web page, the user selects a student, then presses a button and the report for the selected student is viewed inside the report viewer.

The button click event code is as follows:

protected void ButtonReport_Click(object sender, EventArgs e)

{

if (Session["StudentID"] != null &&

!(((string)Session["StudentID"]).Trim().Equals("")))

{

ReportViewer viewer = (ReportViewer)this.ReportContent.Controls[0];

ReportStudent report = new ReportStudent(Int32.Parse((string)Session["StudentID"]));

viewer.Report = report;

viewer.RefreshReport();

}

The above scenario works perfectly..

When deploying to the remote server, change the connection strings accoringly in:

Web.config of web app
Settings.settings and app.config for the report library.

Besides, add the telerik libraries shown in the figure. (By the way, i am not sure if this list is minimal or not...)

and finally, here is telerik relevant portions of my web.config:
