EJB3 problem with Jboss datasource??

I am new to EJB3 and am trying to run through the tutorial from http://www.laliluna.de/ejb-3-tutorial-jboss.html. I don't think my datasource is getting set up correctly. Here is the error from the Jboss server on start up.

13:38:01,717 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

I think the datasource is set up ok? This is from earlier in the output -

13:37:59,967 INFO  [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=ejb3ExampleDS' to JNDI name 'java:ejb3ExampleDS'

Here is my mysql-ds.xml from the C:\jboss-4.2.2.GA\server\default\deploy directory

    <metadata>'
       <type-mapping>mySQL</type-mapping>
    </metadata>
  </local-tx-datasource>
</datasources>

I have tried both
<connection-url>jdbc:mysql://mysql-localhost:3306/test</connection-url>
 and
<connection-url>jdbc:mysql://localhost:3306/test</connection-url>
for the <connection-url> syntax and same error with both.

Also here is my persistence.xml file --

<?xml version="1.0" encoding="UTF-8"?>
<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">
   
      <persistence-unit name="FirstEjb3Tutorial" transaction-type="JTA">
              <jta-data-source>java:/ejb3ProjectDS</jta-data-source>
      </persistence-unit>
 
</persistence>

Is it the datasource causing the error??
