Exception while using embedded openejb for testing in eclipse
Hi *,
i try to run my SLSB Tests on an embedded openejb server - without any extra
configuration. I added all required libs (try and error :-). But now i get a
strange exception. (OpenEJB is in eclipse classpath). How can i reuse the
eclipse classpath for my tests?
Cheers

Hi David,
ok. I got it exactly the way you did. My fault was that i added only some
libs to my eclispe-build-path
geronimo-annotation_1.0_spec-1.1.jar
geronimo-ejb_3.0_spec-1.0.jar
geronimo-jta_1.1_spec-1.1.jar
log4j-1.2.12.jar
openejb-client-3.0-beta-1.jar
openejb-core-3.0-beta-1.jar
openejb-ejbd-3.0-beta-1.jar
openejb-loader-3.0-beta-1.jar
openejb-server-3.0-beta-1.jar
Now i added all libs from the project and ... it's running, but not working
:-(
I open another thread for my new problems.
Thanks alot for your great help and project
Cheers

I was able to get something running using an example from the
downloadable examples zip as follows:
On Command line:
1. cd examples/calculator-stateless-pojo
2. mvn eclipse:eclipse
In Eclipse:
3. Open Eclipse
4. Import "examples/calculator-stateless-pojo" selecting "General-
>Existing Projects into Workspace"
That will get your project into eclipse, but there'll be an "M2_REPO"
variable you have to define. For that you:
5. Preferences -> navigate to "Java -> Build Path -> Classpath
Variables"
6. click New...
7. enter the values Name: "M2_REPO", Path: "/Users/dblevins/.m2/
repository/" (adjust for your machine)
8. OK
That should do the trick. From there you can run the
CalculatorTest.java which will show everything running embedded.
I made some screen shots, but don't have an art program to mark them
up or shrink down the file sizes. None the less, here are a few along
with generated eclipse project:
http://people.apache.org/~dblevins/eclipse-howto/
Hope this helps. Let us know how it goes.

P.S. Anyone out there want to turn this into an article? Could
probably recommend you to a publisher.

Hi Per,
It isn't clear what's causing the issue based on the stack trace
(NoClassDefFoundErrors usually require some debugging). I'm going to
try and convert one of our examples into an eclipse project and see if
I can't get something working. I'll post the workspace when I'm done.
If you'd like to post a workspace that reproduces the issue as well,
that'd be great too. Even if the space I create works, I'd be nice to
know what happened for support reasons.
