I was getting the following exception
| java.lang.ClassCastException at | org.apache.ojb.broker.metadata.MetadataManager.buildDefaultKey(MetadataManager.java:558) | when initailizing OJB in an application deployed on Jboss. The source code is | private PBKey buildDefaultKey() | { | List descriptors = connectionRepository().getAllDescriptor(); | JdbcConnectionDescriptor descriptor; | for (Iterator iterator = descriptors.iterator(); iterator.hasNext();) | { | descriptor = (JdbcConnectionDescriptor) iterator.next(); <== THIS IS LINE 558 | if (descriptor.isDefaultConnection()) | Added logs to display the class of iterator.next() and it was in fact the correct class (JdbcConnectionDescriptor). I then used the code described in http://www.javaworld.com/javaworld/javaqa/2003-07/01-qa-0711-classsrc.html to find out where the class were loaded from. The classes for the objects from the iterator were loaded from: jboss/server/all/tmp/deploy/tmp2436VideoStore.ear The class of the descriptor variable was loaded from: jboss/server/all/tmp/deploy/tmp2604VideoStore.ear For some reason JBoss was loading code from different versions of the ear file during the same session. Stopping JBoss to clean the tmp directory fixed the problem. I don't have an scenario to reproduce the problem, but iit happened after redeploying the ear file about ten times.
