Category: JBossMX Group: v3.2 Status: Open Resolution: None Priority: 5 Submitted By: Fabiano C. de Oliveira (fabcipriano) Assigned to: Nobody/Anonymous (nobody) Summary: UnifiedClassLoader problem with Class.forName() Initial Comment: Running in a : Windows NT sp 6a Sun JDK 1.4.2_04 JBoss 3.2.3 We have done a connector package it in a rar file, and a EJB jar file that use this connector package it in a jar file. When JBoss start for the first time We deploy the RAR and after this the JAR EJB. At this moment all is ok. The problem happen when we redeploy the RAR and the EJB bean after this. So we receive a ClassCastException when we try use the getConection() in the EJB code. After search for the problem in the end we have discover that when the connector use Class.forName() to instance our Connection class it use a previous old UnifiedClassLoader, because this we receive a ClassCastException. But when we use a Thread.currentThread().getContextClassLoader().loadClass() to load the Connector class all works fine after redeploy !!! To simulate this problem we have attached two files. A foo.jar that have a simple example.Foo class and a BeanShell that load the example.Foo using Class.forName() each 10 secunds. To reproduce the problem: 1. deploy foo.jar 2. deploy the beanshell 3. undeploy the foo.jar 4. wait 15 secunds 5. we receive a message log from the bean shell saying that it have found the Foo class !!! But the correct should be a ClassNotFound Exception !!! Is ClassLoader.loadClass is used all works fine. This is a JBoss or Java VM bug ? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=951248&group_id=22866 ------------------------------------------------------- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3 _______________________________________________ JBoss-Development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
