Hi Neil, we put the eclipselink.jar in the Java lib/endorsed folder, as just deploying it does not work. Another possibility - that we do not use - is to put the eclipselink.jar in every WAR/EAR archive that you deploy. Hope this helps.

The only stumbling block I have with EclipseLink is the fact that whenever I update/delete data and I do a em.flush it complains about it not being in a transaction. Now my persistence.xml file is setup as follows: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd";> <persistence-unit name="cnectdDAL" transaction-type="JTA"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <jta-data-source>jdbc/cnectd</jta-data-source> <class>com.cnectd.dal.MimeType</class> <class>com.cnectd.dal.MimeTypePK</class> <exclude-unlisted-classes>false</exclude-unlisted-classes> </persistence-unit> </persistence> This means I am running Container Managed Transactions. So why would it complain about it not being in a transaction? I have googled this error and cannot find anything to help me. I did deploy the eclipselink.jar file to geronimo via the admin console. Any ideas? Regards Neil On Tue, 2011-03-01 at 09:54 +0100, Michael Simons wrote: > Hi Neil, > > We faced a similar situation like you a little time ago.
