    [SOLVED] org.jboss.remoting.InvocationResponse cannot be cast to org.jboss.invocation.MarshalledValue error, making EJB3 call over HTTP w/ JBossAS 4.2.3 and Unified Invoker

      OK, I got the server to a point that it starts with no errors, but when I create an EJB3 client and try to invoke my SSB using HTTP, I get this error:


      Exception in thread "main" javax.naming.NamingException: Failed to retrieve Naming interface for provider http://localhost:8080/unified-invoker/Ejb3ServerInvokerServlet/?return-exception=true [Root exception is java.lang.ClassCastException: org.jboss.remoting.InvocationResponse cannot be cast to org.jboss.invocation.MarshalledValue]

          ... 5 more


      Any thoughts or suggestions on this?   This is JBoss AS 4.2.3 with the unified invoker SAR from



      and JBoss Remoting 2.2.3_SP3.



      My client code looks like this:


         public static void main(String[] args) throws Exception


             Properties p = new Properties();

             p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory");

             p.put(Context.PROVIDER_URL, "http://localhost:8080/unified-invoker/Ejb3ServerInvokerServlet/?return-exception=true");

             p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");     

             InitialContext ctx = new InitialContext(p);

             Calculator calculator = (Calculator) ctx.lookup("CalculatorBean/http");


             System.out.println("1 + 1 = " + calculator.add(1, 1));

             System.out.println("1 - 1 = " + calculator.subtract(1, 1));




      the jars I have linked to the client program are:













      EDIT: looks like I had the wrong URL in my client.  At any rate, got past this error.  Now on to the *next* problem.   This damn unified invoker is going to turn my hair grey prematurely!
