Deploying a Java CORBA application in Web Start

Question

I am a novice to Java Web Start. I have a sample Client-Server application with CORBA as a middle ware. The front end (Client) is in Java and back end (Server) is in C++. The application is run and tested with jar and batch file. Now I want to deploy that application in Java Web Start and JNLP.
I have configured the same by creating a JNLP file and signed jars.
Now as all knows any CORBA application needs a domain file ( .cfg ) and some org.omg classes to communicate with the server by RPC.
I am stuck with how to specify these domain file name, path, CORBA classes etc in my JNLP. Not even that, I can't understand exactly what configuration will make the CORBA apps work properly in Java Web Start so that it can communicate with the server as well. All the Orbix jars's, IDL Stub jars are present and signed. I am giving my JNLP file as a reference. Actually I have tried adding these domain files and CORBA classes as parameters. But as usual it is not working and after running the JNLP the Java console suddenly gets disappeared.

Answer 1

*@ gimbal2 and EJP :*
The firewall is present and allowed to access apps. When I am running the jar of my application from batch file then everything is running fine. The CORBA Server is a remote RHEL5 (Enterprise Linux 5) machine whose 'IP' and 'Hostname' is specified in *"C:\WINDOWS\system32\drivers\etc\hosts"* file. Server is running fine and after starting the Client the Server side remote method is invoked. Data fetched properly and everything is working like a charm.
When running from batch (.bat) file using jar My applications folder hierarchy is something like this.
Test_CORBA_App
------+config ( contains resources file and domain file )
------+lib_6.3 ( contains all Jars)
------+log ( will contaiin the generated log files )
-------runCORBA_App.bat ( the batch file I am running )
As depicted above the folder hierarchy, my domain file resides in "config" folder. The contents of the batch file are as follows :
runCORBA_App.bat
C:\jdk1.6.0_14\bin\java -Xms64M -Xmx512M -Dorg.omg.CORBA.ORBClass=com.iona.corba.art.artimpl.ORBImpl -Dorg.omg.CORBA.ORBSingletonClass=com.iona.corba.art.artimpl.ORBSingleton -jar lib_6.3\UI_Fall_Test63.jar -ORBdomain_name VOIAMODOMAINNEW 1
pause
The following things are specified in the batch file :
1. JDK path : ( C:\jdk1.6.0_14\bin\java )
2. Java VM arguments for max and min memory : ( -Xms64M -Xmx512M )
3. ORB class name: ( -Dorg.omg.CORBA.ORBClass=com.iona.corba.art.artimpl.ORBImpl )
4. ORB singleton class name : ( -Dorg.omg.CORBA.ORBSingletonClass=com.iona.corba.art.artimpl.ORBSingleton )
5. Jar file name to run : ( -jar lib_6.3\UI_Fall_Test63.jar )
6. Domain Name : ( -ORBdomain_name VOIAMODOMAINNEW )
7. Main function args : ( 1 )
I am trying to deploy this simple CORBA application in Java Web Start and JNLP. I kept this in my tomcat server web apps. The folder hierarchy is as follows :
tomcat
---+ bin
---+ conf
---+ ..
---+ ..
---+ ..
---_ webapps
----------+ host-manager
----------+ manager
----------+ ..
----------+ ..
----------_ Test_CORBA_App
-------------------+ config
-------------------+ lib_6.3
-------------------+ lib_6.3-Signed
-------------------+ log
--------------------CORBADemo.jnlp (.jnlp file)
--------------------index.html (.html file)
As you can see I maintained the same folder structure as it was when running from batch file. The jars I am using is signed and kept in lib_6.3-Signed folder.
My updated "CORBADemo.jnlp" is :

N.B
*1. I am running the Tomcat server in my own machine on port 8400 ( for sure, as I have deployed many .war files using this tomcat and all worked ). And using the URL below running the WebStart application.*
*2. I am running the JNLP from my own machine.*
*3. CORBA server is running on a remote RHEL 5 machine as I mentioned before also.*
URL : http://<My Machine IP>:8400/Test_CORBA_App/
As desired the Web Start application will make a call to the remote CORBA server on RHEL5 machine by initializing the ORB and resolving the CORBA NamingService. But exception is occurring as I posted in previous post i.e exception while resolving NamingService.
Now my query is whether the domain file ( DOMAIN.cfg ) is reading/ accessing properly from my machine while running the JNLP or not. Because I presume in Java Web Start special attention is required to read any .cfg file. If everything is fine why the error is occurring.
*@ EJP :* The ORB is desired to run and running on the CORBA Server remote macine i.e RHEL5 machine, because from batch file it is working fine.
Is it so that I need to run the Tomcat Web Server and CORBA Server from the same machine.
