Already set weblogic.jar in the classpath, but "cannot instantiate class: weblogic.jndi.WLInitialContextFactory" error.

Hi,

I have set weblogic.jar in classpath, but still having this error.

Error NamingException: Cannot instantiate class: weblogic.jndi.WLInitialContextFactory

This is part of code:
+++++++++++++++++++++++++
public void PrintStudentInfo(){
             Context initcntx = null;
              Hashtable ht = new Hashtable();
              ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
              ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
              ht.put(Context.SECURITY_PRINCIPAL, "userId");
              ht.put(Context.SECURITY_CREDENTIALS, "password");

BTW, this is just java program.

thanks,

it may not be that it can't find the class, instead that for some reasone it is failing to create it.
