2 persistence.xml files in EAR archive

[longbeach]

Hi,
i have 2 persistence.xml files in my EAR archive.
I have a web project, a client project, an EJB project.

The 2 files are in the web project and in the EJB project :

WEB_PROJECT_NAME/META-INF/persistence.xml
EJB_PROJECT_NAME/META-INF/persistence.xml

If I use a persistence unit in the web project, where will the container look for it first ?

And in general, what are the rules regarding persistence.xml file research in JBoss 5.1.0 GA ?

Thanks for helping.

The details are a bit long to post here. Chapter 6 of the EJB3 Persistence spec has all these details, so that would be a better place to check this.
