Hibernate SessionFactory in a cluster?

Question

I have been developing an application on WLS 8.1.4 with hibernate 3.1.2 .
          On WLS I created
          - adminServer on localhost:7001
          - MyCluster group
          - manageServer1 on localhost:7021
          - manageServer2 on localhost:7022
          I deploy TestEjb.ejb on MyCluster
          TestEjb.ejb
          - META-INF
          - ejbModule.jar
          - hibernate3.jar and lib for hibernate
          * Hibernate 3.1.2 doesn't have problem about ANTLR.
          hibernate.cfg.xml
          <property name="session_factory_name">sessionFactory</property>
          <property name="hibernate.jndi.class">weblogic.jndi.WLInitialContextFactory</property>
          <property name="hibernate.jndi.url">t3://localhost:7021</property>
          <property name="transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
          <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property>
          SessionBean
          public class TestServiceBeanImpl
          extends TestServiceBean
          implements SessionBean
          public java.lang.Boolean testMethod() {
          try {
          new Configuration().configure().buildSessionFactory();
          } catch (Exception ex) {
          log.error("error", ex);
          throw new RuntimeException(ex);
          return null;
          public java.lang.Boolean testMethod2() {
          try {
          InitialContext ct = new InitialContext();
          Object obj = ct.lookup("sessionFactory");
          log.info("obj : " + obj);
          } catch (Exception ex) {
          ex.printStackTrace();
          throw new EJBException(ex);
          return null;
          Test client
          public class TestServiceTestClient2 {
          private TestServiceRemote testServiceRemote = null;
          private TestServiceRemoteHome testServiceRemoteHome = null;
          //Construct the EJB test client
          public TestServiceTestClient2() {
          initialize();
          try {
          testServiceRemote = testServiceRemoteHome.create();
          testServiceRemote.testMethod();
          } catch (Exception ex) {
          ex.printStackTrace();
          public void initialize() {
          try {
          //get naming context
          Context context = getInitialContext();
          //look up jndi name
          Object ref = context.lookup("TestService");
          //look up jndi name and cast to Home interface
          testServiceRemoteHome = (TestServiceRemoteHome)
          PortableRemoteObject.narrow(ref,
          TestServiceRemoteHome.class);
          } catch (Exception e) {
          e.printStackTrace();
          public Context getInitialContext() throws Exception {
          String url = "t3://127.0.0.1:7021";
          Properties properties;
          try {
          properties = new Properties();
          properties.put(Context.INITIAL_CONTEXT_FACTORY,
          "weblogic.jndi.WLInitialContextFactory");
          properties.put(Context.PROVIDER_URL, url);
          return new javax.naming.InitialContext(properties);
          } catch (Exception e) {
          throw e;
          public static void main(String[] args) {
          TestServiceTestClient2 client = new TestServiceTestClient2();
          I'm not sure about property "hibernate.jndi.url". Is it right?
          I create test client to invoke TestServiceBean method testMethod() on localhost:7021 that work I can binding "sessionFactory" on manageServer1 and manageServer2 (I use WLS console view JNDI tree on manageServer1 and manageServer2) and I invoke testMethod2() on localhost:7021, I can lookup SessionFactory object from JNDI.
          Then I change test client to invoke testMethod2() on localhost:7022, I get null from JNDI.
          This is warning on my console
          13 3 2006 18:42:21,968 WARN org.hibernate.impl.SessionFactoryObjectFactory - Not found: 2c9498dc09f356340109f36711790001
          13 3 2006 18:42:21,968 INFO test.service.TestService_8oegc0_Impl - obj : null
          How can i solve the problem?
          Thanks in advance for tips or other suggestions!
          Regards,

ANTLR classloading ?
