Hi,
I am trying to get my webapp to run under an installation of tomcat that already has a webapp that uses hibernate2.2. When I start up tomcat it spits out the mappings for the webapp.
When I attempted to run my webservice which I installed under axis it throws a java.lang.reflect.InvocationTargetException.
Is it possible because two webapps are using different versions of hibernate? Any ideas?

Thanks,
Jeevak

as long as their classes is isolated from each other you shouldnt have a problem.

you could also start by showing the stacktrace ?

I have pasted the stack trace as seen below. It doesnt say much.I have this webservice working on a different instance of a tomcat installation and I made the same changes to this instance too but I get this error.

During tomcat startup I see the following messages that are related to the webapp using hibernate 2.

i dont see any hibernate related issue.

only some axis issues and some hidden exception that occurs. That exception can be anything. If you are worried if its the two apps that "collides" then test if it happens when they just run alone...if it doesnt then you might be "mingling" classloaders/deployments - but that is again nothing do with hibernate ,)

I had a similar issue a week ago. It threw the same exception but the problem was that I hadnt set the properties for the database correctly and there were a couple of hibernate libraries missing.
The webservice wraps every exception into a SOAPException and it is difficult to debug based on the excpetion it spits out. I have all the libraries in place and I have recreated the same environment as on my development machine where the web service performs as expected.
