Tried to foremost a Forms / Reports Server on an all novel server. During startup of the AdminServer, I got an errormessage:

<BEA-000362> <Server failed. Reason: 

There are one nested errors:

oracle.security.jps.JpsException: oracle.security.jps.service.policystore.PolicyStoreException: javax.persistence.PersistenceException: java.lang.ClassCastException: oracle.jdbc.xa.client.OracleXADataSource cannot live on shape to java.sql.Driver

Solution:

In my example it was quite simple: Start the Repository Database in addition to the according listener procedure ... if non running. If running, cheque whether or non the Repository Database tin live on connected past times using the EZConnect ConnectString for Your Repository DB. Pattern for EZConnect is similar this: host.domain:port/servicename
