J2CA0009E: An exception occurred while trying to instantiate the ManagedConnectionFactory class

Troubleshooting


Problem

An EAR was deployed to WebSphere Application Server that was previously used on WebSphere Application Server V5.0 or V5.1 and that uses a data source without going through the migration process in the WebSphere Information Center. When the EJB that used that data source was executed on WebSphere Application Server, the result was a J2CA0009E error due to a NoSuchMethodException. However, using the test connection for the data source in WebSphere Application Server functions properly. In addition to the J2CA009E, a NMSV0605W will be logged in the SystemOut.log
