[jboss-user] [Installation, Configuration & DEPLOYMENT] - Deployment of a J2EE1.3 application fails on JBoss4.2.2

Salut, i have successfully set up a JEE1.4 environment for to test and run my applications using EJB3. Fine! Some days ago i started a migration project, where an old JEE Application has to move from an Oracle-App-Server to JBoss. So i created a new development-context using Eclipse&Jboss-Tools transfered also the ole JDevelopper to Eclipse. The migration is finished, instread of the oracle-descriptor now there is jboss.xml file doing the job. EAR-Build does create a app.ear that i am trying to deploy on my JBoss 4.2.2 (under Linux, with JAVA 1.6), but i do receive the following exception: 11:56:32,447 WARN [ServiceController] Problem creating service jboss.j2ee:service=EjbModule,module=myAppEJB.jar org.jboss.deployment.DeploymentException: Missing or invalid Instance Cache (in jboss.xml or standardjboss.xml); - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: ) at org.jboss.ejb.EjbModule.createInstanceCache(EjbModule.java:1234) at org.jboss.ejb.EjbModule.createStatefulSessionContainer(EjbModule.java:646) at org.jboss.ejb.EjbModule.createContainer(EjbModule.java:579) at org.jboss.ejb.EjbModule.createService(EjbModule.java:342) The exception seems to occur in the context of a stateful session bean. Thats right, my application has a couple of stateless and stateful session beans, that habe been configured on both descriptor file. Does the error indicate, that the application has problems to persists the data of a statefull session bean ?? Some postings on the web inidicate, that i do have to do some <container-configuration> in my jboss.xml, but i do not know how ? Oh, there is another thing i should tell you. I do have 2 datasources, one of them is linked to a read-only oracle-access. When i worked with EJB3 i learned to map persistenc-issues in my persistence.xml to prevetent ambiguous object mapping, but i do not have any persistence.xml in my EJB2.x !!! Thank you in advance for any help! Groovie View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4231582#...
