Hi,
I'm looking for a possibility to replace the path of the persistence.xml, because I need to edit the xml-file with an externally tool without extracting the jar-file.
Could anyone help me?
Thanks!

"The configuration for entity managers both inside an application server and in a standalone application reside in a persistence archive. A persistence archive is a JAR file which must define a persistence.xml file that resides in the META-INF folder. "

"When Persistence.createEntityManagerFactory() is called, the persistence implementation will search your classpath for any META-INF/persistence.xml files using the ClassLoader.getResource("META-INF/persistence.xml") method."

... so you SHOULD, I guess, be able to put a replacement jar earlier in the classpath, and from that persistence.xml config reference your original jar for classes to map.

I haven't tested this myself, though.
