You are correct, I didn't have the hidden-classes element first in the
file. I moved it there and it deploys now. But I'm still getting the
error from Commons Logging that I have more than one version available
which is not allowed. Here's my actual geronimo-web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app
xmlns="http://geronimo.apache.org/xml/ns/j2ee/web-1.0";
configId="MPLCommon">
<hidden-classes><filter>org.apache.commons.logging</filter></hidden-classes>
<context-root>/mpl</context-root>
<context-priority-classloader>true</context-priority-classloader>
</web-app>
Any ideas?
Thanks,
Rich

Greetings all,
I'm new to Geronimo. I'm trying to deploy one of my web
applications that had previously just been deployed in a standalone
tomcat container in Geronimo 1.0. I've tried this with both the
version with Jetty and with Tomcat bundled. The web app uses a
Hibernate/Spring/JSF framework stack. The jars for each project
are bundled in the war file in the WEB-INF/lib directory.
But when I deploy the application I'm getting NoClassDefFoundErrors
for javax/faces/el/VariableResolver and
org/hibernate/HibernateException.
Any ideas what I'm missing here?
My first guess is that a copy of spring included in geronimo is
getting used in your web app instead of the copy you are trying to
use: when our copy tries to load the faces/hibernate classes it
can't find them. If this is the problem you should be able to fix
it by adding spring and hibernate to the hidden classes list in your
geronimo plan for your application.
I think the xml syntax would be (consult
modules/service-builder/src/schema/geronimo-config-1.0.xsd, this is
also somewhere in the distribution such as schema/....)
<hidden-classes>
<filter>javax.faces.el.</filter>
</hidden-classes>
<hidden-classes>
<filter>org.hibernate.</filter>
</hidden-classes>
I regard the need for multiple hidden-classes elements as a bug in
the schema, and it is fixed in 1.1 (which doesn't work right now)
(but not yet in 1.2, it will be fixed there when we merge in 1.1)
Ok, while trying that I saw the context-priority-classloader element
which should load stuff from the web app classloader before any of
the parent classloaders. I set this to true and tried to deploy. I
don't get any messages about javax.faces or org.hibernate now, but I
am getting this now:
org.apache.commons.logging.LogConfigurationException: Invalid class
loader hierarchy. You have more than one version of
'org.apache.commons.logging.Log' visible, which is not allowed.
So, I tried to hide the parent classloaders
org.apache.commons.logging with
<hidden-classes><filter>org.apache.commons.logging</filter></hidden-classes>
But now Geronimo says there's a problem with my deployment descriptor:
Error: Unable to distribute mpl.war: xml problem
Invalid deployment descriptor: [error: cvc-complex-type.2.4a:

From what I can tell, according to the docs and the schema this
should be alright. So what am I missing now?
