Hi,
I'm running two vanilla instances of on the same machines using the "all"
configuration. I have a webapp that looks up the SLSB. This works when the TestEJB.jar and
TestWebApp.war is on the same node. When I delete the TestEJB.jar from the node where
TestWebApp.war is deployed...I expect TestWebApp.war to lookup the TestSessionBean(in
TestEJB.jar on both nodes) to be looked up via HAJNDI.
This doesn't work though...plus the TestSessionBean is not listed in the HAJNDI
section using JNDIView in the jmx-console? Am I missing something here - as I figure this
should work out of the box using JBoss 4.2.0.GA?
My code is as follows:
TestSessionBean implementation
| package com.xxx.test.ejb3.sessionbean;
|
| import org.jboss.annotation.ejb.Clustered;
| import org.jboss.annotation.ejb.LocalBinding;
| import org.jboss.annotation.ejb.RemoteBinding;

| import javax.persistence.Query;
|
| import com.xxx.test.ejb3.entityejb.TestEntity;
|
| import java.util.List;
|
| @Remote(TestSession.class)
| @Local(TestSession.class)
| @Stateless(name = "TestSessionEJB")
| @Clustered(loadBalancePolicy = RoundRobin.class)
| public class TestSessionBean implements TestSession {
| private static final Logger log = Logger.getLogger(TestSession.class);
| @PersistenceContext
| protected EntityManager entityManager;
|
|
| public TestSessionBean() {
| }
|
| public void testMethod() {
| log.info("testMethod() called....");
| }
|
| public void persistEntity() {
| log.info("persisteEntity() called....");
| TestEntity testEntity = new TestEntity();
| testEntity.setName("tom");
| testEntity.setSurname("jones");
| entityManager.persist(testEntity);
| }
|
| @SuppressWarnings("unchecked")
| public TestEntity[] getPersistedEntities() {
| Query query = entityManager.createQuery("select t from TestEntity
t");
| List<TestEntity> testEntities = query.getResultList();
| return testEntities.toArray(new TestEntity[testEntities.size()]);
| }
| }
|
TestSession interface:
| package com.xxx.test.ejb3.sessionbean;
|
| import com.xxx.test.ejb3.entityejb.TestEntity;
|
| import javax.ejb.Remote;
| import javax.ejb.Local;
| import java.util.List;
|
| public interface TestSession {
|
| public void testMethod();
|
| public void persistEntity();
|
| public TestEntity[] getPersistedEntities();
| }
|
jboss.xml:
| <?xml version="1.0"?>
| <!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 4.0//EN"

Global JNDI Namespace:

javax.ejb.EJBLocalObject)
| | +- remote (proxy: $Proxy94 implements interface
com.xxx.test.ejb3.sessionbean.TestSession,interface org.jboss.ejb3.JBossProxy)
|
The HA-JNDI Namespace is empty...
From the logs my cluster of 2 nodes seems to be up and running
correctly...
| 23:58:19,580 INFO [DefaultPartition] New cluster view for partition DefaultPartition

My client JSP to look up the Session Bean looks as follows:
| <%@ page import="com.xxx.test.ejb3.entityejb.TestEntity" %>
| <%@ page import="com.xxx.test.ejb3.sessionbean.TestSession" %>
| <%@ page import="javax.naming.InitialContext" %>

| <%@ page contentType="text/html;charset=UTF-8" language="java"
%>
| <%
| TestSession testSessionBean = null;
| try {
| Properties props = new Properties();
| props.put(InitialContext.PROVIDER_URL, "192.168.1.12:1100");
| props.put(InitialContext.URL_PKG_PREFIXES,
"jboss.naming:org.jnp.interfaces");
| props.put(InitialContext.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| InitialContext initialContext = new InitialContext(props);
| testSessionBean = (TestSession)
initialContext.lookup("TestSessionEJB/remote");
| } catch (Exception e) {
| e.printStackTrace();
| }
| if (request.getParameter("operation") != null &&
request.getParameter("operation").equalsIgnoreCase("method")) {
| testSessionBean.testMethod();
| } else
| if (request.getParameter("operation") != null &&
request.getParameter("operation").equalsIgnoreCase("persist")) {
| testSessionBean.persistEntity();
| }
| TestEntity[] testEntities = testSessionBean.getPersistedEntities();
| %>

and finally, my stacktrace when I delete the TestEJB.jar on one server:
