Thanks in advance .

A trivial web search returns at least the following:

http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.3/doc/Server_Configuration_Guide/html/ch01s02s01.html
http://www.jpox.org/docs/jpa/persistence_xml.html\

You could try doing your own web searches, which would allow you to better tune the results.

It's almost *always* faster to do the research yourself than to wait for someone to answer you, particularly when it's something trivial like this.
