Just to follow up. Thanks for the feedback, it really helps for
people to post things and say "What does this mean, what do I do
next?" We very much appreciate it.
For this particular item, I've added some code to remove the stack
trace and handle the situation with a clean log message giving a link
to where you can get more information, such as:
INFO - Assembling app: /Users/dblevins/work/openejb3/itests/openejb-
itests-app/target/openejb-itests-app-3.0.0-SNAPSHOT
INFO - PersistenceUnit(name=cmp,
provider=org.apache.openjpa.persistence.PersistenceProviderImpl)
ERROR - JAVA AGENT NOT INSTALLED. The JPA Persistence Provider
requested installation of a ClassFileTransformer which requires a
JavaAgent. See http://openejb.apache.org/javaagent.html
INFO - PersistenceUnit(name=openjpa-test-unit,
provider=org.apache.openjpa.persistence.PersistenceProviderImpl)
ERROR - JAVA AGENT NOT INSTALLED. The JPA Persistence Provider
requested installation of a ClassFileTransformer which requires a
JavaAgent. See http://openejb.apache.org/javaagent.html
The javaagent.html will contain the information for setting this up
in maven, ant, as well as when and why you might need the agent.
Again, thanks for the post. We do our best to put the feedback to
good use!

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
