oops, too many things going on at once here....
This nasty and remarkably uninformative exception usually occurs
because some other exception occurred and was ignored earlier in your
app deployment. IIRC I haven't found a way to get tomcat to tell you
what the problem is rather than blythely continuing on as if nothing
is wrong, and then presenting this misleading exception. IIRC I have
always been forced to debug through the tomcat deployment code to
find out what is wrong.
It's possible my memory is bad that if you make sure logging is set
high enough and scour your geronimo log or command line console
tomcat actually does hint at the cause earlier.

I looked into the code where the exception is occuring and it seems
to be choking (Null Pointer Exception) on the context. Evidently
the context is null. I see there is a setContext() method on the

from.
I am focusing on the following part of the stack trace I recieved.
java.lang.NullPointerException

Am I correct in thinking it is a null context OR that part of
the context is null? Any idea what would cause this? I do NOT
have a geronimo-web.xml in the WAR that is deployed with the ear.
This is the web.xml that is in the WAR.
<?xml version="1.0" encoding="UTF-8"?>

see double instances for display-name and I am wondering could that
be the cause of anything. If so it should have choked during
deployment and not at runtime.
This is what was generated my the tool I have to use. Believe it
or not this is one of 3 xml files that make up the entire contents
of the WAR. The WebServicesServlet class is in the jar that I
installed as a common lib. The other 2 xml docs are WAS 6.0
specific so should be ignored. I may take David's advice and try
to deploy again without the WAR but as of now the powers that be
want to to try the whole shebang. I have a feeling the servlet
routing class will need the WAS files to route the service requests
anyway.
Anybody know what might cause the NPE? I will try and deploy
without the WAR next
thanks

Ear deployed and it is trying to start I would assume it is
something with the EAR however I find it odd that a root cause is
a Null Pointer Exception. Do any one of you developers know the
area of code the NPE is occurring and what might be causing it?
thanks

I used the webconsole and added it to Common Libs. It ended up
creating a directory under the repository named dlochart (not
sure where it got that from) and dropped the jar under the name I
gave it. I looked and I saw axis so i blindly followed and added
this to my plan.
<sys:dependency>
<sys:groupId>geronimo</sys:groupId>
<sys:artifactId>sharedlib</sys:artifactId>
<sys:type>car</sys:type>
</sys:dependency>
I still received the same exception so I looked again and I saw
there was an axis under geronimo which told me that I need to
sdjust my dependency so I guessed it would need to be this:
<sys:dependency>
<sys:groupId>dlochart</sys:groupId>
<sys:artifactId>ibm-runtime</sys:artifactId>
<sys:type>jar</sys:type>
</sys:dependency>
Am I correct on this considering I have a jar under
$geronimo_home/repositories/dlochart/ibm-runtime/6.1.0 ?
Either way I recieved the same exception as below. Any idea what
the exception might mean?
thanks

This ear includes a WAR which is merely a WebServiceRouter (ibm
class), EJB WebService Session Bean implementation, and some
JARs that the code depends upon.
Note:
The WAR router servlet is an IBM specific class that lives in a
jar that is not in the ear as it is expected to be in the WAS
system and I assume available to all. I added this jar to the
lib directory under the geronimo install. I hope this is
sufficient for this if not I would like to know the best
strategy for deploying this jar preferrably outside the EAR.
thanks
Doug
