Installing SSL Certificate on Tomcat

2010-02-16T03:01:00.000-08:00

Recently I installed SSL certificate on tomcat. Thought below information might be helpful for others installing SSL certificate on tomcat. There are two ways of installing SSL certificate in tomcat:

CA gives only certificate against CSR.
CA gives you certificate and private key

CA gives only certificate against CSR

In this scenario, you create CSR request using jdk keytool and send CSR file to CA (Certificate Authority). Then CA send gives you the certificate to import. In this scenario you need to perform below two steps:

Download chain certificate from CA where you obtained the certificate and import it in new keystore with following command:

  keytool -import -alias root -keystore  -trustcacerts -file

Import CA provided certificate into the same keystore as used above:

keytool -import -alias tomcat -keystore  -trustcacerts -file

CA gives you certificate and private key

In this scenario CA provides you two thing i.e private key and certificate. you need to perform below two steps:

Download chain certificate from CA where you obtained the certificate.
Till now you have 3 things namely private key, certificate and chain certificate. Use following command to make your keystore:

openssl pkcs12 -export -in mycert.crt -inkey mykey.key -out mycert.p12 -name tomcat -CAfile myCA.crt -caname root -chain

For openSSL install microsoft tool available at http://www.slproweb.com/products/Win32OpenSSL.html

DragonFireSDK pre-release Vs Monotouch Review by IPhone developer

2010-02-10T04:33:00.000-08:00

I am IPhone developer and always looking for ways to get rid of Objective-C syntax. I have evaluated Monotouch and now evaluating DragonFireSDK both. Below is what I found about both alternatives:

The good think about DragonFireSDK is that it provides complete development environment in C++ on windows machine
DragonFireSDK hides typical IPhone application architecture when writing in Objective-c in Xcode, while MonoTouch doesn't hide the architecture of typical IPhone application. In Monotouch developer must follow Iphone application typical design. It only provide c# syntax but design is same as that of IPhone typical application.
Niether DragonFireSDK nor Monotouch provides IPhone objective-C Core-Data API features like things that save our lots of time in developing app in IPhone when playing with backend storage.

IPhone Development on Windows Plateform

2010-02-07T23:23:00.000-08:00

Some great news for IPhone developer. Now IPhone developer can use windows machine to do IPhone development.
The DragonFireSDK will let you create iPhone Apps in Windows in C++. You can run them on a provided simulator, debug using Visual Studio (not sure if it's full or Express versions) and install it on a (shush) jailbroken iPhone.

However where it gets interesting is that you can use it to put apps in to the App Store and get paid. You can do this is in the traditional way as a registered developer(and pay $49.95 to Zimusoft for their Windows sdk) or do it for free through Zimusoft who distribute it as part of their brand but pay you all (they take nothing) of the royalties through paypal

Installing Android problem (failed to rename directory)

2010-01-24T06:42:00.000-08:00

Recently I started development on Android platform. When I first installed Android sdk 2.1 through SVD Manager, I encounter a very strange error below. The major problem with this error is that it occurs after taking longer time of downloading the component. For my internet connection it took about 23 min which it requires for downloading the component. After downloading the component it renames the tool folder which causes this error to occur :

Downloading Android SDK Tools, revision 4

Installing Android SDK Tools, revision 4

Failed to rename directory E:\android-sdk_r3-windows\tools to E:\android-sdk_r3-windows\temp\ToolPackage.old01

-= Warning ! =-

A folder failed to be renamed or moved. On Windows this typically means that a program is using that folder (for example Windows Explorer.) Please close all running programs that may be locking the directory 'E:\android-sdk_r3-windows\tools' and try again.

Skipping 'SDK Platform Android 2.1, API 7, revision 1'; it depends on 'Android SDK Tools, revision 4' which was not installed.

Downloading SDK Platform Android 2.1, API 7, revision 1

First I thought that I mistakenly opened tool folder in some other application so I started SVD manager again which took me again 23 min and after that I got the error again. Very frustrating. Since I was using windows 7 so I thing there might be some problem with windows 7. I started googling on this problem and then reviewing few ppls work around I came to know that this is typical problem with Antivirus. So when I turned off my Antivirus the error resolved. Hope my this post would definitly helps to novice you are just entering in the realm of the android development.

Nexus One Vs IPhone Review

2010-01-18T22:11:00.000-08:00

I have been using IPhone for some time and recently after the arrival of Nexus, I got chance to use it. Below are my unbiased review about both IPhone and Nexus as an end user.

Nexus doesn't have multi-touch feature while IPhone already had it. This seems to me the major feature missing in Nexus. This would make it hard atleast for IPhone community to use it.
Nexus user feeling experience cannot compare with IPhone. IPhone provide much smoother and sophisticated user experience.

I was planning to buy nexus but now after using it in my company I would not want to purchase it. It needs to much mature for user experience as compare to IPhone

Adobe Flex

Adobe Flex

This blog is extracted from my presentations that I gave one and half years ago (May 02, 2007) in my firm to introduce flex technology and make my company realize the importance of flex and its future. I am glad that my prediction made at that time about flex future was right. Rightnow flex is the hottest RIA solution in the market and its hard to find its good developer. I am also glad that there are around more than 4 project in flex that my firm is doing and it has developed good flex expertise developer during last two years that I can bet probably among few excellent flex resource in the world.

Following are the contents of the blog:

Introduction

Since the invent of internet and its improvement in the bandwidth endeavors were being made to develop RIA (Rich Internet Application) that would be same as desktop applications. Researches, cientist and developers (especially companies like Adobe and Microsoft) made their efforts to develop a platform that would make RIA dream a reality.
There comes the race among different companies for providing a platform for developing RIA. Microsoft made some serious efforts few years ago and come up with RIA and SOA based technology called “Microsoft SilverLight”. Similar effort has been made by Adobe whose outcome is in the form technology called Flex.

Successful stories

Followings are the Flex successfuly implementations:

How RIA Development Challenges resolved in Flex

Provide a familiar programming model: Flex provide a familiar programming model for both java and .net Programmers that is based on OOPs.
Leverage existing architecture: Flex provide integration with existing application servers and SOAs. So provide organization who have invested heavily on application servers and SOAs to implement RIA.
Support standard protocols and application programming interfaces (APIs): Flex has support for Standard Protocol and APIs like HTTP, XML and SOAP/Webservices etc. Flex provides easy integration with famous java frameworks like Hibernet, Xfire and Spring etc.
Follow common key design patterns: Flex provide MVC based Framework known as “Cairngorm”/"PureMVC".
Integrate with existing processes: Flex can be easily integrated with existing development processes like using automated build script ant for deployment etc..
Provide rich tooling: Flex provide rich tools.

Flex Runtime Architecture

What is Flex Programming Model?

The Flex programming model is made of:

MXML, an XML language used to declaratively lay out the user interface of your application.
ActionScript, an ECMAScript compliant, object-oriented programming model. With some syntactical differences, ActionScript looks and feels similar to Java, and supports the same object-oriented constructs: packages, classes, inheritance, interfaces, strong (but also dynamic) typing etc.
An extensive set of class libraries. The online API documentation is available in a Javadoc-like format.

How Flex Code is compiled?

The Flex source code (.mxml and .as files) is compiled into Flash bytecode (.swf) that is executed at the client-side by the Flash virtual machine.

There are different ways you can use the Flex compiler (mxmlc):

From the command line
As part of an ant script
Using FlexBuilder: the compilation process is integrated in the IDE
Using the web compiler (available with the Flex Data Services). This is similar to the JSP compilation model: The first time an application is requested it is compiled into bytecode, which is then cached to serve subsequent requests.

Flex product line

The Flex product line includes:
- The Flex SDK which is free and includes the Flex libraries, the compiler (mxmlc), the debugger, and the documentation.
- Flex Data Services (FDS), an optional set of server-side components deployed in your J2EE application server. FDS includes a Java RPC service, publish/subscribe messaging, and data management services. FDS is free for a single-CPU deployment (FDS Express), and is licensed per CPU when deployed on multiple CPUs.
- FlexBuilder, an optional IDE for Flex development. Built as an Eclipse plug-in, FlexBuilder includes a design view and a code view, code hinting, visual debugging, etc. FlexBuilder is licensed on a per developer basis.
- Optional charting components licensed on a per developer basis.
We can develop and deploy Flex applications entirely for free using the SDK and the IDE of our choice.

Flex for Dotnet developer

WebORB for .Net

WebORB offers a complete native .NET implementation of Flex Remoting (RPC) and Flex Messaging and in the latest release (3.0) a partial implementation of the Flex Data Management Services capabilities.
Flex applications can rely on WebORB to provide functionality similar to that found in Adobe's Flex Data Services product.

How to bind Dotnet Object?

Some queries about the technology

Would Adobe win RIA race against Microsoft?
- Adobe made Flex open source. Microsoft is also planning to make Silverlight opensource.
- Adobe is addressing large enterprise applications as well whereas Microsoft in spite of its struggle didn’t able to penetrate yet in large enterprise apps. For example Microsoft ERP solution Great Plain not warmly welcomed. On the other hand SAP is using Flex. Also Flex provides integration with Message Queue that makes it to be used with any middleware solutions.
- Adobe has proved about its cross platform claims, whereas Microsoft past has some questions about it.
- Microsoft Windows XP tour that is available at %SystemRoot %\system32\tourstart.exe is made in flash :)
- According to Adobe, 97% of internet users have flash player installed in their browser.
Would Job market forJ2EE developer give preferences to developers having Flex skills?
- A/c to a survey there has been an increase of 20% demand for J2EE developers having flex skills.

Ruby On Rails For Java Developer

2008-11-03T01:23:00.000-08:00

Ruby On Rails For Java Developer

In this blog I would discuss ruby on rails breifly from java developer perspective. Following are the contents of this blog:

What is Ruby on Rails?

Ruby on Rails is an open source Ruby framework for developing web-based, database-driven applications. One can develop web applications atleast ten times faster than any other typical java framework. Rails’ primary goal was to bridge the gap between PHP and J2EE by providing an extensible, reusable web framework that offered an enjoyable, productive development experience. That goal was certainly met, and Rails became more than just a web framework.

How Ruby On Rails acheive rapid development with quality?

Rails takes full advantage of Ruby programming language.

Rails use two rails guiding principles:

Less software Rails require developer to write few lines of code to implement application.
Convention over configuration Ruby On Rails put an end to verbose long XML configuration files. There is no configurations files in Rails. Instead of configuration files, a Rails application uses a few simple programming conventions that allow it to figure out everything through reflection and discovery.

What is Ruby?

Ruby is a pure object-oriented programming language. Below we will compare it with java.

Ruby for Java developer

Similiarties:

Memory is managed via a garbage collector.
Objects are strongly typed.
There are public, private, and protected methods.
There are embedded doc tools (Ruby’s is called RDoc). The docs generated by rdoc look very similar to those generated by javadoc.

Differences:

You don’t need to compile your code. You just run it directly.
There are different GUI toolkits. Ruby users can try WxRuby, FXRuby, Ruby-GNOME2, or the bundled-in Ruby Tk for example.
You use the end keyword after defining things like classes, instead of having to put braces around blocks of code.
You have require instead of import.
All member variables are private. From the outside, you access everything via methods.
Parentheses in method calls are usually optional and often omitted.
Everything is an object.
Variable names are just labels. They don’t have a type associated with them.
There are no type declarations. You just assign to new variable names as-needed and they just “spring up” (i.e. a = [1,2,3] rather than int[] a = {1,2,3};).
It’s foo = Foo.new( "hi") instead of foo = new Foo( "hi" ).
The constructor is always named “initialize” instead of the name of the class.
YAML tends to be favored over XML.
It’s nil instead of null.

Rails Architecture

Rails Application Structure

Following chart is above structure description:

Folder Name	Description
app	Holds application specific code. This includes models, views, controllers, APIs and helpers.
components	Components are self-contained packages of controllers and views. These are normally utilized when there is a need to reuse a view that has associated reusable behavior.
config	Configuration files for Rails environment, URL routes and database
db	Database schema and migrations.
doc	Holds application documentation generated from RDoc.
lib	Application specific libraries.
log	Development and production server logs.
public	This folder is made available to the web server. It contains the dispatch scripts along with static content such as images, javascripts, stylesheets and default html files.
script	Helper scripts for development server, automation, generation and plugin management.
test	Unit, functional and integration tests along with test fixtures.
tmp	Temporary directory for development server.
vendor	Contains plugins and external libraries the application depends on.

Rails App folder Structure

Model, View and Controller

Model:

Rails interacts with models through the ActiveRecord component.
ActiveRecord models are based on the Active Record pattern defined in Martin Fowler’s “Patterns of Enterprise Application Architecture.”
Active Record defines a model structure that encapsulates a row in the database and domain logic on that data.
The ActiveRecord component requires only the database connection information to be configured in order to work.
There is no need for explicit object to database mapping. ActiveRecord elicits field information directly from the database itself at startup time.
It is possible to have a fully functional model that just extends from the ActiveRecord::Base class.
class Post < ActiveRecord::Base End
Currently, ActiveRecord supports the following 9 databases: DB2, Firebird,MySQL, OpenBase, Oracle, PostgreSQL, SQLServer, SQLite and Sybase.
Associations must be defined in the models themselves and those relationships follow specified naming schemes.

Views:

RHTML	This is the default view for Rails applications. RHTML renders HTML based content back to a client web browser. RHTML also contains Ruby expressions that allow for programming within the view
RJS	RJS templates are Ruby based javascript views. This type of view is used for asynchronous javascript calls (AJAX) made to a Rails app. RJS templates allow the view to execute javascript effects and manipulate the page where the AJAX call originated.
RXML	RXML is Ruby generated XML code. It uses builder templates to easier construct an XML document to return to the client. Rails automatically returns RXML views as the XML content type.

All of the views in Rails are routed through a controller.
A controller action is responsible for passing information to a corresponding view. Any variables created in the instance of the Controller action will be made available to the view as well as application and controller specific helper functions.
<h1>Posts</h1> <% for post in @posts %> <h2><%=post.title%></h2> <p><%=post.body%></p> <% end %>

Controller:

Controller take a dispatched request and decide what to do with it.
Controllers are responsible for interacting with the model, choosing which view to render and any redirects that take place.
The action is no longer a standalone class but simply a method within a controller.
class PostsController < ActionController::Base
def add end def edit end def delete end
end
The default routing format to invoke one of these actions is: controller/action/id.
class PostsController < ActionController::Base
def show @post = Post.find(params[:id ]) end
End
By default Rails will render the corresponding view file with the same name as the action. Following is show.rhtml file
<h1><%=@post.title %></h1> <p><%=@post.body %></p> posted by %=@post.author%

Creating Simple Application

Step 1- Creating App

Step 2- Create Database

Step 3 – Provide database connection Entry in cookbook2/config/database.YAML

# MySQL (default setup). Versions 4.1 and 5.0 are recommended. # # Install the MySQL driver: # gem install mysql # On MacOS X: # gem install mysql -- --include=/usr/local/lib # On Windows: # gem install mysql # Choose the win32 build. # Install MySQL and put its /bin directory on your path. # # And be sure to use new-style password hashing: # http://dev.mysql.com/doc/refman/5.0/en/old-client.html development:
adapter: mysql database: mydb username: root password: root host: localhost

Step 4- Generate Application

For Recipe:

For Category :

Lets Look at generated Code

Model Code:

class Category < ActiveRecord::Base end

Controller Code:

class CategoryController < ApplicationController
def show @category = Category.find(params[:id]) end
def new @category = Category.new end
def create
@category = Category.new(params[:category]) if @category.save
flash[:notice] = 'Category was successfully created.' redirect_to :action => 'list'
else
render :action => 'new'
end
end
End

View Code:
<h1>Editing category</h1> <% form_tag :action => 'update', :id => @category do %> <%= render :partial => 'form' %> <%= submit_tag 'Edit' %> <% end %> <%= link_to 'Show', :action => 'show', :id => @category %> | <%= link_to 'Back', :action => 'list' %>

Step 5- Run development server

How to install livecycle ES Server quickly for playing with it?

This article is useful for those who wanted to install LiveCycle ES Server very quickly (in just 20-30 min without going into hassles of configuring things) to just play with it.

When I was first time installing livecycle ES server on my laptop to play with LiveCycle ES, I went through number of adobe documents. I was willing to find a way of quickly installing it without going into hassles of lots of configuration details. After spending few days for different LiveCycle Server installation documents and trying them, I was able of find the way of quick installation through using Jboss turnkey installation.In following I would discuss Adobe LiveCycle Server installations types available in general and how to install LiveCycle Server quickly using Abode Jboss turnkey installation.

Overview of LiveCycle Server Installations:

Live Cycle Server installation can be done with several configuration depending on type of J2EE application Server and database.

Followings are the application server for which LiveCycle Server can be configured:

Jboss Server

Bea WebLogic

IBM WebSphere

Followings are the databases that can be used for LiveCycle ES server:

DB2

MySQL

SQL Server 2005

Oracle

Now as you might have guessed there can be several installation choices (using one J2EE server type with different type of database). So there is 12 installation choices. Adobe provides liveCycle Server for each J2EE Server type. When you start LiveCycle Server installation with any J2EE server, you would have choice of eighter using Automatic configuration of J2EE Server for use with LiveCycle or using manual configuration.You would also have to manually set up database as describe in Adobe PrepareInstall.pdf doc.

Now if you would like to get yourself away from hassles involving setting up Database and J2EE SErver for LiveCycle to use then be happy there is a very quick easy installation available from Adobe. This installation is Called "Jboss turnkey installation". This installation includes mySQL database installation already setup for use with LiveCycle and preconfigured Jboss server for use with LiveCylce. All you need to do is to press double click the LiveCycle Setup and follow instruction just like any Microsoft product and click next next buttons. Read following pdf doc from adobe for installation steps in detail:

www.adobe.com/go/learn_lc_installTurnkey.

You can download Jboss turnkey LiveCycle Setup from here.

The good thing about this setup is that its for development use and it can be installed on Microsoft XP where as other LiveCycle installations are aimed by Adobe for use on Microsoft Windows Server 2003 Sp2 which Adobe clearly mentioned in its prepareInstall.pdf.
