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 org.jboss.ejb3.stateless.StatelessRemoteProxy; local class incompatible: stream classdesc serialVersionUID = 2583299153931800023, local class serialVersionUID = -9097306519795868]
at org.jnp.interfaces.NamingContext.lookup(
at org.jnp.interfaces.NamingContext.lookup(
at javax.naming.InitialContext.lookup(
at com.ejb.bean.FirstEJB3TutorialClient.main(

where is my client application running on a separate machine.

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

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

BookTestBean class:


public class BookTestBean implements BookTestBeanRemote {


EntityManager em;

FirstEJB3TutorialClient class:

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


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

Can someone please help me out??

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.
