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.

Hello,
I'm using Apache Aries 0.4 (from IBM WAS) and OpenJPA 2.1.1-SNAPSHOT
also from IBM.
I have a data source defined in WAS: Jndi Name : jdbc/dupcheckcts
I have my persistence.xml as follows:
<?xml version="1.0" encoding="UTF-8"?>

When I deploy the EBA and start the app I'm getting the following
error:
Caused by: <openjpa-2.1.1-SNAPSHOT-r422266:1141200 fatal user error>

Any ideas please?
Thanks in advance!
