We are anxiously awaiting OpenJPA to finish it's unenhanced support
so we can do CMP and JPA without a java agent. Until then, include a
chunk like this in your pom and you should be good to go. It's a lot
of tags, but it's essentially just doing two things: copy the agent
jar from the repo to your build dir; include the java agent when
surefire runs tests.
Definitely something we need to get up on the website documented.
Thanks for the reminder!

Hi,
I've been having trouble using openejb from within a unittest with
maven2. I've managed to get this working from within eclipse and
from the command line but when running from within maven2 the test
fails with a classnotfoundexception.

At first i thought this was a classpath issue but i've checked
using a mvn -X that the openejb-javaagent jar file is included in
classpath. The code that appears to cause the problem is from
org.apache.openejb.javaagent.Agent:
ClassLoader systemCl = ClassLoader.getSystemClassLoader();
Class<?> systemAgentClass = systemCl.loadClass
(Agent.class.getName());
Field instrumentationField = systemAgentClass.getDeclaredField
("instrumentation");
instrumentationField.setAccessible(true);
instrumentation = (Instrumentation) instrumentationField.get(null);
The snippet appears to be looking for the Agent.class within the
system classloader and i'm guessing that the maven-surefire-plugin
uses its own classloader to run its tests.
Can anyone shed any light on this or is there a work around for this?
Regards,
Gareth
