I created a EAR project and an application Client project using RAD 7.5. Client project has been included as a module in EAR. The client project has Main.java (Standalone class).

RAD7.5 has been configured to use local WAS6.0 test environment. JMS resources have been configured in WAS6.0 test environment and SI bus has already been created in WAS. My final goal is to send a message to SI bus queue using Main.java class. But I am getting the below exception during InitialContext lookup itself.

Exception in RAD7.5 console is below:

InitialContext starts....

I see, Provider URL value as "iiop://localhost:21005/"; in Universal Test Client GUI in RAD. RAD uses the default jdk which comes in RAD v7.5. Please help to troubleshoot what is causing this error?. I googled it, but couldn't find the cause. Thanks

Can you try using following format of provider URL and post your findings? Generally the boot strap address is 2809.

I tried with below options, getting the same exception.






Perhaps, I never changed port number after WAS installation, so, the default port should be 2809 for corbaloc. Where can I look for the port number? Am I missing something else?

You should be able to find the port numbers in WAS under "Servers -> Application servers -> [server1] -> Configuration -> Ports"

The configured port numbers are below. Here the BOOTSTRAP_ADDRESS port# is 21005. I already tried with this port

I think your problem is related to classpath. The client application which is trying to do the JNDI lookup is not able to locate the initial context factory class in its classpath. Fix the classpath and you should be all set.

I'm able to access InitialContextFactory in Main.java (Client) class, also Websphere lib files have been included in the class path. So, don't see any classpath issue for InitialContextFactory class. any other clue?

I agree. Time ago, I encountered the same problem, I included some jars of WAS runtime (I just don't rember which ) and the issue has been fixed.
By the way, I remember that those jars were not lightweight... moreover, I was not sure that I could redistribuite them with my application, so I gave up
and searched for another solution....
