Missing configuration resource for path /org/apache/struts/tiles/chain-config.xml when deploying on jboss using struts 1.3.8

[David Sharp <ds...@gmail.com>]

I'm hoping someone here can help me figure out what is going on with
my project.  I have an ear structured as follows (apologies for the
ASCII art tree diagrams):

edalrs.ear
|-lib
|  |-struts-core.jar
|  |-struts-extras.jar
|-edalrs-web.war

The war file has the following structure:

edalrs-web.war
|-WEB-INF
|  |-lib
|     |-struts-taglib.jar
|     |-struts-tiles.jar
|-META-INF
  |-MANIFEST.MF

The  MANIFEST.MF has the following classpath entries:
lib/struts-core.jar lib/struts-extras.jar

When deployed on websphere, the application runs fine.  When deployed
on jboss, I get the message:  "Missing configuration resource for path
/org/apache/struts/tiles/chain-config.xml".

I've modified the ActionServlet class to spit out some debugging data
and here is what I got:
14:23:12,019 INFO splitting and resolving paths:
'/org/apache/struts/tiles/chain-config.xml'
14:23:12,019 INFO Unable to locate

,addedOrder=47}
14:23:12,051 INFO Path = /org/apache/struts/tiles/chain-config.xml
14:23:12,051 INFO Msg = 'Missing configuration resource for path
/org/apache/struts/tiles/chain-config.xml'

I have specified a <loader-repository> in my jboss-app.xml to turn on
parent-delegation as follows:

<jboss-app>
   <loader-repository>
	com.acme.edalrs:loader=eDalrs-ear.ear
   <loader-repository-config>java2ParentDelegation=true</loader-repository-config>
   </loader-repository>
</jboss-app>

If I'm not mistaken, the web classloader should delegate to its parent
(the EAR classloader) to try and load the resources.  The parent
should fail, and then the web classloader should load the file out of
the WEB-INF/lib/struts-tiles.jar.

This isn't happening, and it's driving me crazy.  I appreciate any
help anyone can shed.  The only reason we have the taglib and tiles
jars in the war is so that the .tld files for the tag libraries can be
found.  I've tried extracting the TLDs from the jar, and placing them
in WEB-INF, and then placing the taglib and tiles jars into the ear
with the rest of struts, but the behavior is the same.

Thanks,
Dave
