The hidden classes works great for Jetty. I will make sure this is included in the IBM article so that other folks don't have this problem. Thanks for the help!

I have been running Grails 0.5+ applications on Geronimo 2.x and this works w/o problem as long as you hide specific packages. Your geronimo-web.xml should look like the following one:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="">

I am writing an article for IBM developerWorks on using Grails and Geronimo
together. However, I am unable to deploy a Grails WAR to Geronimo.

I first tried it with Geronimo 2.1.1 with Jetty. The error I got was a
NoClassDefFound for org.apache.commons.fileupload.FileItemFactory. This
class is the Geronimo repository, and is also included with the Grails war.
It's the same version for both.

Next I tried it with Geronimo 2.1.1 with Tomcat. This time I got a dom4j

Next I tried the Little G distribution. It worked perfectly. I had also
tried standalone Tomcat with success as well, so I guess this should not
have been too surprising.

Obviously I have to point a finger at Grails or Geronimo, and since it works
fine on Tomcat or Little G, I am pointing the finger at Geronimo. The
Geronimo/Jetty error sure smelled like a class loader problem, but I have no
clue on the Geronimo/Tomcat. Note, in all cases I included a Geronimo
deployment plan inside the WAR (/WEB-INF/geronimo-web.xml)

Any ideas/advice is greatly appreciated.
