Geronimo and Grails

[michaelg]

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 InvalidXPathException.

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.

It doesn't matter whether the plan is included in the app or supplied  
externally.

I'm surprised you are seeing different results on "big" and "little"  
geronimo.  You should be getting the same classloader for your app in  
either server.  Would it be possible to share your app so we can take  
a look at what is going on?

If I was writing an article on geronimo I would structure the project  
so it consisted of one or more geronimo plugins and would show how to  
construct a specialized server including those plugins.  This is by  
far easier if you are using maven, which I realize might not fit with  
the requirements you are working under.  There are some instructions  
on how to do something similar here:

Hello,

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="http://geronimo.apache.org/xml/ns/j2ee/web/jetty-1.2">

     <environment>
         <moduleId>
             <groupId>yourGroupId</groupId>
             <artifactId>yourArtifactId</artifactId>
             <version>yourVersion</version>
             <type>war</type>
         </moduleId>

         <hidden-classes>
           <filter>org.springframework</filter>
           <filter>org.apache.cxf</filter>
           <filter>org.apache.commons</filter>
         </hidden-classes>

     </environment>

     <context-root>/yourContextPath</context-root>

</web-app>


Thanks,
Gianny

Would it have worked in little G because little G does not include
commons-fileupload and so there is no chance of loading a class from one
classloader and using it in another?

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!
