I was facing the same issue and here was my resolution I had wrongly spelled my jta data source in IBM Admin Console and was using a different name in my persistence xml so Websphere couldn't connect. Please check the Resources Tab in the Admin Console and validate your jta data source name as declared in persistence xml
