Hi,
I managed to set up a test which reproduced this. I found a couple of
ways around the problem:
One way was to use JDK 1.6 (I could only reproduce your error with 1.5,
but maybe that's just my machine...)
The other way was to remove javaee-api-5.0.1 from my classpath, and
replace it with the various Java EE spec jars from Geronimo.
Specifically I had to use the following:
axis2-jaxws-api-1.3
geronimo-activation_1.1_spec
geronimo-annotation_1.0_spec
geronimo-ejb_3.0_spec
geronimo-interceptor_3.0_spec
geronimo-j2ee-connector_1.5_spec
geronimo-jacc_1.1_spec
geronimo-jms_1.1_spec
geronimo-jpa_3.0_spec
geronimo-jta_1.1_spec
geronimo-stax-api_1.0_spec
geronimo-ws-metadata_2.0_spec
jaxb-api-2.1.3
This feels pretty nasty to me though, I'm not sure I really recommend
it. I don't know what your production environment is, but I definitely
wouldn't start swapping out jars in a standalone OpenEJB server/
OpenEJB-Tomcat / Geronimo setup (and I guess if you're using the
standalone server or the Tomcat plugin you might run into the same issue
when you deploy your app).
I'm happy to look at doing some work on the OpenEJB javaee-api jar, or
on the server itself to try and come up with a more elegant solution,
but I think it would need a sanity check from one of the other
developers first (any thoughts, anyone?).

Hi,
I am using openejb to test a code that use jaxb-impl-2.1.3.jar which
requires Jaxb 2.1 API.
The openejb javaee-api.jar, that seems to be loaded first by the
classloader, contains Jaxb API 2.0 and make my test failed.
I noticed that Jaxb 2.0 is the one required by Java EE specs but I would
like to known whether there is a simple way to override this in OpenEJB?
Thanks in advance
