RE: Aries/OpenJPA strange error - A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName?
Hi, That's the error Open JPA gives you when the DataSource fails. This is probably because your JNDI lookup is failing. Is there a valid DataSource at jdbc/dupcheckcts ?

Re: Aries/OpenJPA strange error - A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName?
Hi Matt, The error message you're seeing is from OpenJPA. It produces the same error message whether there's no datasource defined or the datasource is defined but can't be looked up. However, in this case I notice you only have a jta datsource defined. It couldn't hurt to also define a non-jta-datasource. Whether it's required depends on the JPA implementation (some optimise reads), but better safe than sorry. I also notice your version numbers are pretty high. Which version of WAS are you using? Is it the Liberty profile? If it is, you'll need to add resource references for your datasource and then look it up using a java:comp/ namespace.

Re: Aries/OpenJPA strange error - A JDBC Driver or DataSource class name must be specified in the ConnectionDriverName?
Hello Everyone.
Thanks for the reply. I found the issue and solved it. Actually this DAO
code was inherited legacy code and the developer was creating the
EntityManagerFactory and EntityManager from the code as follows:
*{EntityManagerFactory factory =
Persistence.createEntityManagerFactory(DuCk_jpa); *
*EntityManager entityManager = factory.createEntityManager();*
while I had added the following code for the EntityManager to be injected!
* @PersistenceContext(unitName = DuCk_jpa)*
*EntityManager entityManager = null;*
while the above code worked in a normal EAR env, it did not work in EBA env.
I removed the hard coded (Factory etc) and it works fine now!
Thanks
Matt
