h.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
h.put(Context.PROVIDER_URL,"iiop://127.0.0.1:2809");
// InitialContext ctx = new InitialContext(h);
InitialContext ctx = new InitialContext();
Object obj=ctx.lookup("test"); // this is line 30 from error
try

The same code works when put in a servlet.

Why have you commented
InitialContext ctx = new InitialContext(h);
Remove
InitialContext ctx = new InitialContext();

I was testing the client on the same jvm so was trying both way. by passing the properties it gives a context factory error so for compilation sake i was trying without it. but i dont know y it gives malformed url when the same thing is working in the servlet.
Thanks for replying

here is the error that i get if i pass the properties to the context

Are you sure that you are using the right jar file at the client side.

yes u m using the same jar files. do i need to package the stub files of the ejb or something?
