Hello Folks,
I've got a simple EJB deployed to JBoss3.0.0 running in combination with Tomcat 4.0.3. Calling this EJB from a command line client works very fine using code like this:
final String factoryClassName="org.jnp.interfaces.NamingContextFactory";
final String providerURL = "jnp://195.30.48.4:1100/";
final String packages = "org.jboss.naming:org.jnp.interfaces";
Hashtable env=new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, factoryClassName);
env.put(Context.PROVIDER_URL, providerURL);
env.put(Context.URL_PKG_PREFIXES, packages);
// create initial context
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("ejb/TestCMPBean");
EntityControllerHome home = (EntityControllerHome) obj;
EntityController controller = home.create();
... and so on.
Using exactly the same code within a (SIP) servlet container running on another system cause the following error message:
Caught an exception: java.lang.ClassCastException: $Proxy0
java.lang.ClassCastException: $Proxy0

I'm not sure about this "$Proxy0" error. I've heard something about dynamic proxy generation. Could the problem be somewhere in this context ?
Would appreciate any help or any hints,
Michael.

Anyone have a suggestion ?
