Question

I am getting Exception with Open JPA .

I have created WAS Data Source. Here is My Persistence XML

http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd”>

<persistence-unit name="App11" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>java:comp/env/jdbc/mydatasource</jta-data-source>  
     <class>vo.Entity</class>
     <properties>
        <property name="openjpa.TransactionMode" value="managed"/>
                <property name="openjpa.ConnectionFactoryMode" value="managed"/>
    </properties>
    </persistence-unit>

I am getting this exception while executing.

Try adding resource-ref in your web.xml with runtime descriptor file (ibm-web-bnd.xml) as suggested in Websphere Datasource with a given JNDI name?
