I have an application that uses EJB and JPA2.0 with eclipselink. I have been able to deploy it successfully and the application starts successfully but when i try to access the uri of the webservice i keep getting different errors depending on what i do.

Here is my web.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <res-type>javax.transaction.UserTransaction</res-type>
    <res-auth>Container</res-auth>
</resource-ref>
</web-app>

And my persistence.xml is below

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="BACPOnline5PU" transaction-type="JTA">  <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>jdbc/infopool</jta-data-source>
<properties/>
</persistence-unit>
</persistence>

I have a PersistenceService class that i use to create persistence from my webservices. i create my lookup like this

private PersistenceService() { 
    try {
    this.em = (javax.persistence.EntityManager) new InitialContext().lookup("java:comp/env/persistence/BACPOnline5PU");
    this.utx = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
    } catch (NamingException ex) {
        throw new RuntimeException(ex);
    }
    }

I get the error below.

java.lang.RuntimeException: com.ibm.websphere.naming.CannotInstantiateObjectException: Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object.

Thanks

I would recommend create datasource in websphere and map to reference in web.xml

web.xml

<resource-ref>
    <res-ref-name>jdbc/datasource</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

And use reference in persistence.xml

persistence.xml

<jta-data-source> java:comp/env/jdbc/datasource</jta-data-source>

During deployment process you shoud map reference 'jdbc/datasource' to real datasource.
