I try to return an Interface of a serializable Object and simply access a getter but all I
get is a ClassNotFoundException:

the test:
| public class EJBTester
| {
| public static void main(String[] args)
| {
| RessourceBean res = null;
| try
| {
| Properties props = new Properties();
| props.setProperty("java.naming.provider.url",

| props.setProperty("java.naming.factory.url.pkgs",

|
props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| //
| props.setProperty("java.naming.factory.initial",
"com.sun.enterprise.naming.SerialInitContextFactory");
| //props.setProperty("java.naming.factory.url.pkgs",
"com.sun.enterprise.naming");
| //props.setProperty("java.naming.factory.state",
"com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
| System.setProperty("java.security.policy",
"client.policy");
| System.setSecurityManager(new RMISecurityManager());
| InitialContext ctx = new InitialContext( props );
| //res = (RessourceBean) ctx.lookup("org.test.ejb.RessourceBean");
| res = (RessourceBean)
ctx.lookup("TestEJB/RessourceBeanImpl/remote");
| if (null != res)
| {
| Ressource r = res.findRessource(null);
| if (null != r)
| {
| System.out.println("id = " + r.getId());
| }
| }
| }
| catch (Exception e)
| {
| e.printStackTrace();
| }
| }
|
| }
On the client I only added the interfaces and retrieve successfully the SSB .. And the
funny thing is as you might have noticed on glassfish it works without any problems it
fetches the (ressource)implemenation via RMIClassloader ;)
Any hints/suggestions?
