9:38 a.m.
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 :
javax.naming.NamingException: Could not dereference object [Root exception is
