[eclipselink-users] JTA and driver class name

[Zdenek Machac <xmachac2@xxxxxxxx>]

Hallo,

we use OpenJPA implementation in Weblogic 10.3 cluster environment but we want to migrate 
to EclipseLink (Oracle TopLink). But there is one stopper.

We use DB connection (DataSource) maped as global JNDI with custom user access (only one 
internal user can access this JNDI resource). Therefore we can not use direct JNDI string 
in persistence.xml becase only described user can obtain connection instance from JNDI.

If we try use JTA and specify driver name EclipseLink JPA says:

"PersistenceUnitInfo ProjektPU has transactionType JTA, but doesnt have jtaDataSource"

Is there any way to specify transaction-type="JTA" without jta-data-source and use property

  <property name="eclipselink.jdbc.driver" value=" ... "/>

with own implementation driver class name which wrap obtaining DB connection from JNDI?

Thanks.
