Problem using HA-JNDI and Fail Over ----------------------------------- Key: JBCLUSTER-32 URL: http://jira.jboss.com/jira/browse/JBCLUSTER-32 Project: JBoss Clustering Issue Type: Bug Security Level: Public(Everyone can see) Environment: JBoss 4.01sp1, Windows XP Professional, Sun JDK 1.4.2_07, Apache 2.0.53 Reporter: Roberto Assigned To: Adrian Brock Fix For: Q3Y5 Attachments: NamingException Error.jpg, testcasecluster.ear, Working Result.jpg I have 3 machines: "HostA" : Load balance base on Apache 2.0.53 with mod_jk 1.2.x with sticky session "ClusterB" : Jboss AS 4.0.1 sp1 with my ear with war and ejb modules "ClusterC" : Jboss AS 4.0.1 sp1 with my ear the same than in ClusterB in my ear i have also a jndi.properties to use HA-JNDI: Code: java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.provider.url=jnp://localhost:1100 java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces #jnp.partitionName=DefaultPartition Load balance is configure for sticky session. My client is a standard browser (Internet Explorer / Firefox). So a user using browser access to the HostA and so the request is forward for example to ClusterB. For now all work fine: the request is captured from a Servlet/JSP the lookup on JNDI using for example: try { ABSEQBAuthHome vHome = (ABSEQBAuthHome) new InitialContext().lookup("java:comp/env/ejb/ABSEQBAuth"); } catch (Exception vErr) {} Setting a jndi.properties in the ear, this force to use port 1100 (HA-JNDI) Now i shutdown (CTRL-C) ClusterB. The user in the same browser session (or in another) do another request and so the load-balance try to use again ClusterB, but now is died and so correctly forward the request to the alive clusterA. The request is always capture from the servlet/jsp that done another lookup (always using HA-JNDI), but now a NameNotFoundException occurs. I think that when the shutdown occurs all ejb are undeploy from the HA-JNDI.... I have prepared an EAR to test it (testcasecluster.ear). Use this step to replicate the problem: When HostA, ClusterA and ClusterB are online, try to access to: http://hosta/testcasecluster/TestCase.jsp (to login user "user" with psw "user") Ok.. at this moment all work fine. Now showtdown a cluster (using shutdown command or CTRL-C) When cluster is down try to access again to the same url. At this moment nothing works! I need to use HA-JNDI without change my java code. Thank You Roberto
