Description

« Hide

OpenJPA's default logging implementation has a concept of a diagnostic context, roughly stolen from log4j. The basic idea is that in a configuration file, the user can specify a diagnostic context string that will be printed out with each log message. The result is that if a user has multiple EntityManagerFactories running in the same JVM, she can distinguish between the different logging outputs, even if they all just go to stderr.

The JPA spec requires that persistence units are named uniquely. This presents us with an opportunity: we could check for the existence of multiple EMFs and, if found and the user did not specify a diagnostic context, automatically set the logging diagnostic context based on the name of the persistence unit.
