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 ?

From: mattmadha...@gmail.com To: user@aries.apache.org Hello,I'm using Apache Aries 0.4 (from IBM WAS) and OpenJPA 2.1.1-SNAPSHOT also from IBM.
