NoClassDefFoundError exception in InitialContext()

[Henry Sun]

Hi,
I am writing a Java thin client in WSAD5 and testing with JUnit. Exception pops up when creating a context. The code is very simple:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc:iiop:localhost:2809");
initialContext = new InitialContext(env);
The exception message is:
junit.framework.AssertionFailedError: Exception in constructor: testFindCategory (java.lang.NoClassDefFoundError: com/ibm/CORBA/iiop/ObjectURL

Can anyone help me figure it out?
Thanks!

This is because you didn't add ws_runtime.jar into your classpath.

Your classpath must contain ws_runtime.jar which will be available in %WEB_SPHERE_HOME%/Appserver/deploytool/itp/plugins/com.ibm.websphere.v61_6.1.0/
This is specific to WAS 6.1. Check your WAS manual for respective runtime jar.

I think this solves your issue.

I am writing a Java thin client in WSAD...

How 'thin' is your 'thin client?' Remember, anything with a main method will need to be run from a J2EE client container. The J2EE client container will have the appropriate JAR files needed by the WebSphere runtime.

If it's a Servlet, well, the point is moot.
