[JBoss Seam] - Re: @Remote still shown as
by bluetrade
It seems to be bound anyways to "ClassName/remote" even though this is not explicitly listed. I assume this because if I specify this, I get an error that differs from the error I get when misspell something in this string.
However, none-the-less I cannot really figure out what's going on, since I get the following error:
| javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.ejb3.stateless.StatelessRemoteProxy; local class incompatible: stream classdesc serialVersionUID = 2583299153931800023, local class serialVersionUID = -9097306519795868]

My interface:
| import java.rmi.Remote;
|
| @javax.ejb.Remote
| public interface ChatServer extends Remote {
| public void sendMessage(Message msg);
| public void addClient(ChatClient client);
| public void notifyClients();
| }
|
My class:
|
| import java.rmi.RemoteException;
| import java.rmi.server.UnicastRemoteObject;
|
| import javax.ejb.Stateless;
| import javax.persistence.EntityManager;
|
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Name;
| @Stateless
| @Name("chatServer")
| public class ChatServerImpl extends UnicastRemoteObject implements ChatServer {
|
| @In(create=true)
| EntityManager entityManager;
|
| public ChatServerImpl() throws RemoteException {
| System.out.println("Started Chat Server!");
| }
|
| public void addClient(ChatClient client) {
|
|
| }
|
| public void notifyClients() {
| System.out.println("Notifying clients");
|
| }
|
| public void sendMessage(Message msg) {
| // TODO Auto-generated method stub
|
| }
|
| }
|
The client:
import javax.naming.Context;
| import com.sun.corba.se.impl.javax.rmi.PortableRemoteObject;
|
| public class ChatTester {
| public static void main(String args[]) {
| try {
| Context jndiContext = getInitialContext( );
| Object ref = jndiContext.lookup("jboss-seam-myties/ChatServerImpl/remote");
| ChatServer srv = (ChatServer)javax.rmi.PortableRemoteObject.narrow(ref, ChatServer.class);
|
| srv.notifyClients();
| } catch (javax.naming.NamingException ne){ne.printStackTrace( );}
| }
|
| public static Context getInitialContext( )
| throws javax.naming.NamingException {
| Properties p = new Properties( );
| p.put(Context.INITIAL_CONTEXT_FACTORY,
| "org.jnp.interfaces.NamingContextFactory");
| p.put(Context.URL_PKG_PREFIXES,
| " org.jboss.naming:org.jnp.interfaces");
| p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| return new javax.naming.InitialContext(p);

| }

I am not sure whether this is related to seam, but I thought so... Maybe you have any clues to this?
Thank you very much in advance and by this time, for reading the post :)
