[jboss-user] [EJB 3.0] - EJB3 an JBoss client java.io.InvalidClassException

[wilfried.deguil]

Hello,

I start to develop with EJB3. I'm using JBoss 4.2.1.GA. I deploy my Entity and Session Bean on the server. I verify that my session bean at loaded with the JMX console.

Code of my Session Bean :

@Stateful    
public class SiteDetailsManagerBean implements SiteDetailsManagerRemote {
 @PersistenceContext
 private EntityManager em;
 private int id;
 private String	label;         	 
 private String	securityLevel;
 public SiteDetailsManagerBean(int id,String label) {
}
    ...
}

code of my interface Session bean :

@Remote
public interface SiteDetailsManagerRemote {
 void createSite(String label);	
 void removeSite(int siteId); 
 SiteDetailsManagerBean getSite(int siteId);
 List	getAllSites();
 public void testReponse(String str);	
}

code of my client :

public class Client {
 private static SiteDetailsManagerRemote siteDetailsMngrRequest;
 private static void getRemoteRequest() throws Exception 
 {
   if (null != siteDetailsMngrRequest){ return ; }                         
   String JNDINameRemote =  "SiteDetailsManagerBean/remote" ;	
   Context context = new InitialContext();			
   siteDetailsMngrRequest = (SiteDetailsManagerRemote)context.lookup(JNDINameRemote);  }
 public Client(String[] args) { }	

 public static void main(String[] args) {...}



So when I start my client, on the red line I get this exception :
