Hi guys, I've installed JBoss4.2GA and I'm trying to get our application EAR file working in it. The EAR deploys fine in our previous version of JBoss 3.2.7. When I try to deploy in JBoss4.2GA, I get the error below. This LocalTXConnectionManager class exists in JBoss3.2.7 in the jboss-jca.jar in the default/lib directory but the same class is missing in jboss-jca.jar in JBoss4.2GA. Any help would be greatly appreciated!! Wasnt sure whether to post this in the Installation/Deployment forum or here. Thanks! 10:43:09,679 ERROR [JBOSSDataSourceFactory] Error in bindDataSource source method javax.management.ReflectionException: Class not found: org.jboss.resource.connectionmanager.LocalTxConnectionManager at org.jboss.mx.server.MBeanServerImpl.handleInstantiateExceptions(MBeanServerImpl.java:1258) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:1237) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:248) at org.jboss.mx.server.MBeanServerImpl.createMBean(MBeanServerImpl.java:294) at com.emptoris.zport.config.datasource.jboss.JBOSSDataSourceFactory.bindDataSource(JBOSSDataSourceFactory.java: at com.emptoris.zport.config.datasource.jboss.JBOSSDataSourceFactory.access$000(JBOSSDataSourceFactory.java:46) at com.emptoris.zport.config.datasource.jboss.JBOSSDataSourceFactory$DataSourceCreator.run(JBOSSDataSourceFactor Caused by: java.lang.ClassNotFoundException: org.jboss.resource.connectionmanager.LocalTxConnectionManager at org.jboss.mx.loading.UnifiedLoaderRepository3.loadClass(UnifiedLoaderRepository3.java:607) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:1207) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4059643#...
