Thanks for the help on the users list, Quintin! It's great to have you around.

With netbeans it's not an easy task.

It comes from the server you selected. The best option is to select a
Geronimo server, though the Geronimo plugin for netbeans is only
available in 6.8, and only supports an older version of geronimo 2.0
or something - it technically supports them all, but doesn't recognize
newer installations as it looks for the geronimo-kernel jar with a
specific version. I got around this by modifying it's source and
changing the file it looks for to the one in my geronimo installation
and all it's features worked from here. Though it's very limited and
can only deploy WAR archives, it does help with the classpath
problems.

The best practice option for this is to define the property in your
project's run options. When you go into the project's properties and
to the Run page where you select the server, you'll see a text field
at the bottom that allows you to enter options. Define the property
there, something like: -Dj2ee.platform.SOMETHING.classpath=

An alternative is to select a null server (open your project's
configuration files and remove/empty the server selection).

And another alternative (which I don't recommend you do unless you
don't need the other servers ever again) is to edit netbeans' internal
representation of the glassfish servers and modify their classpaths.

Try the first option first, if it doesn't work reply to this e-mail. I
was successful in using that technique, so if it doesn't work for you
we only missed something.

Hi Quintin,
You are right. Looks like the jar from the glassfish libs is the responsible culprit. Now that you mention it, I am not even sure why its showing up in the first place at all. Its definitely not in the project library and I do 
not reference it anywhere in the code either. The only place I see a
reference for it is in the netbeans 'private.properties' files as part of 
the j2ee.platform.*.classpath entries.
Thanks for all the help. Hopefully once I get rid of that jar I shouldn't be having any more problems. In the meanwhile, if you know any tips on getting 
rid of it, please feel free to let me know :)

Hey,

Is there any reason you have the glassfish libs on your classpath.
Some of these libs do cause problems with OpenEJB. I can't recall
exactly which ones, but I myself has spent many minutes filtering the 
culprits out. In the end you don't even need the glassfish libs on
your classpath at all. OpenEJB covers the JavaEE spec, so you don't
need them. When you deploy to glassfish they'll be there anyway.

If you decide to keep them on your classpath, here is an unrelated
tip. Depending on the netbeans version, some of them leave the
"package" option for the server libraries checked, which means the
glassfish libs are packaged inside the EJB. You might want to uncheck 
this - will make your ejb much smaller and build faster. I haven't
noticed that happening with the more recent netbeans versions though. 

I'm not sure if this is your problem, but with those
application-client.xml messages, and the Glassfish webservers jars on 
the classpath, it might just be the cause.

Hi there,

I just installed openEJB v3.1.1 in order to unit test the ejbs I am
creating
in my webapp as part of a TDD approach that I am trying to incorporate. Anyways, I am currently getting the following errors and cannot seem to 
resolve them.

######################################################################################################################################################################

and so on for a bunch of classes.
I looked at the 1/0/com/sun/codemodel/*.class files and noticed that they are supposed to be in the jaxb-xjc-2.1.8.jar. So I went ahead and added 
that
to the OpenEJB library, but that did not resolve the isse. Can you tell 
me
what I need to do to get rid of these Exception messages?

Thanks for the help in advance !!!
