Head First EJB - JNDI Error

[Ron Khera]

I am using the Head First EJB book. I can't seem to get the AdviceClient code running. All the code for the Advice example compiles and I have sucessfully deployed the EJB. The error seems to be with the initialContext object properties. I not familiar with JNDI and would appreciate some help.

C:\Projects\advice>java -classpath /projects/advice/AdviceAppClient.jar;. AdviceClient
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet pa
rameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
at AdviceClient.go(AdviceClient.java:16)
at AdviceClient.main(AdviceClient.java:10)

Thanks !!

You will need to specify the INTIAL_CONTEXT_FACTORY and the PROVIDER_URL for the InitialContext. That's what the exception trace is suggesting.

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
        "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, "t3://localhost:7001");

Also, if you are using Sun App server, you might take a look at the documentation.
