Troubleshooting
Problem
Worklight Server may log the following warning messages related to the OpenJPA runtime when the Worklight Console is first accessed: [err] 83 WorklightPU WARN [Default Executor-thread-2] openjpa.Runtime - An error occurred while registering a ClassTransformer with PersistenceUnitInfo: name 'WorklightPU', root URL [file:/c:/IBM/Liberty85/usr/servers/defaultServer/libs/worklight-jee-library.jar]. The error has been consumed. To see it, set your openjpa.Runtime log level to TRACE. Load-time class transformation will not be available. [err] 2490 WorklightPU INFO [Default Executor-thread-2] openjpa.Runtime - Starting OpenJPA 1.2.2 [err] 2647 WorklightPU INFO [Default Executor-thread-2] openjpa.jdbc.JDBC - Using dictionary class "com.worklight.database.WorklightMySQLDBDictionary". The Worklight integration with OpenJPA does not require the registration of a ClassTransformer at load-time, however according to http://openjpa.apache.org/integration.html (towards the bottom of the page), the OpenJPA / Spring integration will always log warnings when a ClassTransformer is not registered at load-time.
Resolving The Problem
These warning messages can be safely ignored
