Sean,
Nice name by the way.
JOnAS uses a custom class loader that has some
bugs under 1.2 VMs and above. The class loader mentions
the problems in comments in the code. I haven't dug into
the problem yet but the comments in the code seem to point
to the new security model in 1.2 and above VMs as being
the problem. I haven't filed a bug report with the JOnAS
folks yet. I was going to take a stab at fixing it first.
Basically the problem is that the custom class
loader is used if you deploy from a jar because it needs
to find a specific ejb-jar.xml and jonas-ejb-jar.xml in
the jar file. You are likely deploying multiple beans so
if the normal Java class loader was used it would always find
the first ejb-jar.xml and jonas-ejb-jar.xml file and not
the correct files from the specific jar files you
are trying to deploy. Anyway, the custom class loader
is supposed to default back to loading from the class
path if it doesn't find what it is looking for in the
specific deployed jar but this doesn't happen. So the
result is EVERY class not already loaded in the VM that
your bean needs must be in the bean's jar file not in
the classpath.
That is one work around, the other is that you deploy
with the XML file external from the jars so the normal
class loader will always be used which is what we did
because putting every class each bean needed in it's
jar was not feasible.
The source with the bug is
com.lutris.classloader.MultiClassLoader in case you
want to take a look at it.
I copied this to e-mail the list in case anyone
else is having this issue.
Thanks,
Sean
