[jboss-user] [Beginners Corner] - Wrong class when getting started.

I am trying to get started with EJB3 in JBoss. I have installed JBoss4.0.4GA and patched in jboss-EJB-3.0_RC9-FD. Then I have written my first Stateless Session Bean, derived from the training course, and (after some trouble) deployed it. I then try to access it with my Client, using the code below. public static void main (String[] args) throws Exception { Properties props = new Properties () ; props.setProperty ("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory") ; props.setProperty ("java.naming.provider.url", "localhost:1099") ; InitialContext ctx = new InitialContext (props) ; Object o = ctx.lookup (CalcImpl.class.getSimpleName ()) ; Calc calculator = (Calc) o ; System.out.println ("1 + 1 = " + calculator.add (1, 1)) ; System.out.println ("1 - 1 = " + calculator.subtract (1, 1)) ; } But the Object o returned from ctx.lookup is not, as I expect, a CalcImpl Object, but a NamingContext Object, which then causes a Class Cast error. What am I doing wrong? Incidentally, after patching, the JBoss startup throws this exception: ... 83 more 11:42:02,648 ERROR [MainDeployer] Could not create deployment: file:/C:/JBoss/jboss-4.0.4.GA/server/default/deploy/ejb3-entity-cache-service.xml org.jboss.deployment.DeploymentException: No ClassLoaders found for: org.jboss.cache.TreeCache; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: org.jboss.cache.TreeCache) at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:196) at org.jboss.system.ServiceController.install(ServiceController.java:226) Should I worry? Should I report? Thanks for any help Alec View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3977843#...
