[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Can't find a persistence unit named 'null'

[ercanclk]

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>
  | 
doc-ds.xml looks like this:

  | <?xml version="1.0" encoding="UTF-8"?>
  | 
  | <!-- $Id: mim-ds.xml,v 1.1 2007/06/29 21:08:56 ugur Exp $ -->
  | <!--  Datasource config for MySQL using 3.0.9 available from:
  | http://www.mysql.com/downloads/api-jdbc-stable.html
  | -->
  | 
  | <datasources>
  |   <local-tx-datasource>
  |     <jndi-name>DOCDS</jndi-name>
  |     <connection-url>jdbc:mysql://localhost:3306/document</connection-url>
  |     <driver-class>com.mysql.jdbc.Driver</driver-class>
  |     <user-name>root</user-name>
  |     <password>atasrv123*</password>
  |     <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
  |     <!-- should only be used on drivers after 3.22.1 with "ping" support
  |     <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
  |     -->
  |     <!-- sql to call when connection is created
  |     <new-connection-sql>some arbitrary sql</new-connection-sql>
  |       -->
  |     <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
  |     <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
  |       -->
  | 
  |     <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
  |     <metadata>
  |        <type-mapping>mySQL</type-mapping>
  |     </metadata>
  |   </local-tx-datasource>
  | </datasources>
  | 

And finally this is the error :
