JBoss AS6 - Failed to resolve schema nsURI= location=persistence

If you encounter the following error when deploying under JBoss AS6:
“Failed to resolve schema nsURI= location=persistence”

The chances are that you are missing the name-space for the persistence.xml file. So examine your persistence.xml file and replace the tag with the following:

<persistence
 xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
 version="1.0">

And this should help you get rid of the above error.

cheers.
