Hi

When i am deploying my projects to server, it gives an error. My project structure looks like this:

Doc-EJB3
- src
- doc.ejb3.entitiy // source package
- doc.ejb3.service //another source package
- META-INF
- MANIFEST.MF
- persistence.xml
- doc-ds.xml
- jndi.properties


persistence.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<persistence>
 <persistence-unit name="DOCPU">
 <jta-data-source>java:/DOCDS</jta-data-source>
 <properties>
 <!-- <property name="hibernate.hbm2ddl.auto" value="create-drop"/> -->
 </properties>
 </persistence-unit>
</persistence>

<?xml version="1.0" encoding="UTF-8"?>
