Hi, I got the following error when i tried to lookup on statefull session bean. java.lang.ClassCastException: $Proxy78 cannot be cast to com.vs.uhome.model.session.LoginSession com.vs.uhome.model.util.PropertyUtil.getLoginSession(PropertyUtil.java:239) com.vs.uhome.view.serv.mainServ.onLogin(mainServ.java:101) com.vs.uhome.view.serv.mainServ.doPost(mainServ.java:79) javax.servlet.http.HttpServlet.service(HttpServlet.java:710) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) Here i m giving statefull session bean @Stateful(name = "uhomeSession") public class LoginSessionBean implements LoginSession { @PersistenceContext(unitName = "Model") private EntityManager em; private PropertyLogger pl; private Ruser sessionUser; private FinderMethods fm; public void logon(String userEmail, String password, boolean encrypted) throws UnknownException, WarningException { pl.write("Entered logon(String, String, boolean)", 1, "DefaultSessionBean", "logon"); if ((userEmail == null) || userEmail.matches("^\\s*$")) { throw new WarningException(new CatalogHelper("UHOME_002002", 1, "DefaultSession", "logon")); } if (password == null) { password = ""; } if (encrypted) { logon(userEmail, password); } else { String ecPasswd = PropertyUtil.encodeStr(password + userEmail); logon(userEmail, ecPasswd); } pl.write("Leaving logon(String, String, boolean)", 1, } } And i m doing lookup like this public static LoginSession getLoginSession() throws UnknownException, WarningException { LoginSession ls; Context ctx; try { ctx = getInitialContext(); } catch (WarningException we) { throw we; } catch (NamingException ne) { throw new UnknownException (new CatalogHelper("UHOME_900035", ne.getMessage(), ne, "PropertyUtil", "getLoginSession")); } try { ls = (LoginSession)ctx.lookup("uhomeSession/remote"); return ls; } catch (NamingException ne) { throw new UnknownException (new CatalogHelper("UHOME_900036", new Object[]{"LoginSession", ne.getMessage()}, ne, "PropertyUtil", "getLoginSession")); } } and i got the JNDI view like this +- uhomeSession (class: org.jnp.interfaces.NamingContext) | +- remote (class: java.lang.Object) | +- remoteStatefulProxyFactory (proxy: $Proxy79 implements interface org.jboss.ejb3.ProxyFactory) Can you please tell what is the problem.
