Hi, I am trying to access a remote stateless bean from a standalone client. I am using JBOSS application server.But I am getting the following exception:

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]
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:723)
at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:588)
at javax.naming.InitialContext.lookup(InitialContext.java:351)
at com.ejb.bean.FirstEJB3TutorialClient.main(FirstEJB3TutorialClient.java:20)

where FirstEJB3TutorialClient.java is my client application running on a separate machine.

The code snippets for the various classes used are as follows:

BookTestBeanRemote interface:
@Remote
public interface BookTestBeanRemote {
public void testBook();
public void testCustomer();
public void testRelation();
}

BookTestBean class:

@Stateless
@RemoteBinding(jndiBinding="testBean")

public class BookTestBean implements BookTestBeanRemote {

@PersistenceContext

EntityManager em;

FirstEJB3TutorialClient class:

public class FirstEJB3TutorialClient {
public static void main(String[] args) {
try {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
properties.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming rg.jnp.interfaces");
properties.put(Context.PROVIDER_URL, "10.0.5.243:1099");
Context context = new InitialContext(properties);
BookTestBeanRemote beanRemote = (BookTestBeanRemote) context
.lookup("testBean");

beanRemote.testBook();

where 10.0.5.243 is the IP address of the server where JBOSS server is running.

Can someone please help me out??

Thanks

Please do not duplicate post. The EJB3 forum is the more appropriate forum, this forum is for Object Relation Mapping tools only, which does cover JPA.
