[quote] Hi all,
We tried to use JPA with hibernate in WLS9.2 and after some ime, I get the following exception thrown.

(org.hibernate.util.DTDEntityResolver) - trying to resolve system-id [http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd]
[Feb 15 19:10:21] DEBUG (org.hibernate.cfg.EJB3DTDEntityResolver) - recognized EJB3 ORM namespace; attempting to resolve on classpath under org/hibernate/ejb



The following are my configurations
WLS version : 10.0 (not sure of service pack. I have asked systems team to give some info on this)
Hibernate version : 3.0 (hibernate3.jar)
Environment : Linux
persistence_1_0.xsd file is available in hibernate-entitymanager.jar


The following is the snap shot of my persistence.xml file.
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"

Where is the exception? and you are using Apache Open JPA.
