Hey guys,

Here is what I'm trying to do: we are switching over to using JAXB and Jersey for all our REST services and XML/JSON serialization needs.

So far, I have been able to get a simple test working where some beans are annotated, some test objects created and these are perfectly serialized to either XML or JSON and return to the client upon request. I mostly wrote this based on some of the examples around the Internet, where the an HTTPServer is created and started in the main method.

I am now trying to put this same example into a WAR file and deploy it to my local Tomcat server so I can test it in a more production-like environment. Seeing as I was not able to get it to work on Tomcat 5.5.27 following the instructions here I went ahead and upgraded to Tomcat 6.0. Same instructions, same outcome, a huge InvocationTargetException.

What exactly am I missing guys?

That's part of the ginormous spew in catalina.out.

Also, here is my web.xml

    </servlet>

    </session-config>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

Any help with this would be greatly appreciated! Thanks in advance.

You have probably a conflict somewhere, check your jar files and see if there are no duplicate classes. Use Tattletale to locate the problem
