Thanks for responding Jesse. I'm still working through the issue with some of the Geronimo folks. I'm still curious though whether that was the intended behavior of the code or not. Seems odd to me you would call out to a method that can never return, but then have code that can be executed as if a return from the method is expected.

Ok, even though I suggested posting over here (was in the middle of a
production push before), I have one ~guess~ answer that doesn't involve
looking at the code.
It sounds like the classloader is finding your hivemind-1.1.jar twice for some reason? (my recollection of jars specifically inside the classloader 
are less sure...have only had experience trying to define dynamic
classloaders that can unload class definitions from a specific jar source 
for "hot swapping" things).
It it were because the jar was loaded twice into the classpath I think the 
error would make sense. Ie if someone has inadverantly included two
different hivemind jar versions in their classpath then that would be bad. 
(though I think the manifest contains a unique key entry or crc-ish
functionality doesn't it?)

That's my best guess. If you can somehow get a printout of the classpath
used to start up geronimo it might shed more light on this.

Hello...

I am trying to deploy a simple Tapestry app to Geronimo and am having
some issues.  I've pasted the stack trace in here to see.  I'm pretty
sure its a class loading issue with Geronimo, because I got it works on
JBoss and Tomcat just fine.  But, it did get me looking at some of the
Tapestry code, and I was curious about one thing I saw.
I was getting the following error (see below for the full stack trace)...
12:54:14,328 ERROR [[/equinox-tapestry]] Servlet /equinox-tapestry threw 
load() exception
org.apache.hivemind.ApplicationRuntimeException: Error: Module hivemind
is duplicated!  Definition in
jar:file:/C:/tools/geronimo-1.2-SNAPSHOT
/config-store/44/war/WEB-INF/lib/hivemind-1.1.jar!/META-INF/hivemodule.xml 
has been ignored in favor of existing definition from
jar:file:/C:/tools/geronimo-1.2-SNAPSHOT
/config-store/44/war/WEB-INF/lib/hivemind-1.1.jar!/META-INF/hivemodule.xml 
.



So, I went and looked in
'RegistryInfrastructureConstructor.addModuleDescriptor' and saw where
its calling '_errorHandler.error' if the map of _modules already
contains the current ModuleDescriptor passed into the method as a
parameter. The thing that caught my attention was that the method makes 
a 'return;' call after calling '_errorHandler.error'.
When I went and looked at the implementation of '_errorHandler.error', I 
notice that it throws a runtime exception, so the calling method never
gets a chance to return.  I'm curious if this is intentional.

The reason I wonder is because, just hacking around a bit, I modified
the implementation of the 'error' method so that it simply logs an
error, but does not throw an exception.  I re-built, and re-deployed...
and the app works just fine now.  (I should mention I had to skip the
tests to build it, because there were failures if I didn't.)

Like I said, if its working in JBoss and Tomcat, but not in Geronimo,
its probably a Geronimo issue.  I was just curious to find out if this
implementation was how the developer intended.  Thanks...
