classLoader is not connected to a domain in JBoss EAP 5?

Issue

• The web application is intermittently getting this error( classLoader is not connected to a domain (probably undeployed?) for class oracle.sql.LnxLib). Some part of the application works using this connection pool, but other parts of the application are getting this error with the same connection pool. This error happens after the JBOSS server is restarted. The oracle ojdbc5.jar file in the WAR file is being used.

• After the deployment, if the user is trying to access the portal/web application, they are getting the following error:

org.jboss.util.NestedSQLException: Error; - nested throwable: (java.lang.IllegalStateException: BaseClassLoader@4320e76d{vfszip:/C:/JBoss/server/default/deploy/redhattest.ear/redhattest.war/} classLoader is not connected to a domain
