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.
java.lang.IllegalStateException: Unable to initialize agent

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
