Hi All,
I'm working on integrating restlet and spring for use in a web app to be run
under Tomcat. After reading up on the Spring extension (thank you Jerome) I
have decided to go the restlet as the main controller route. This is due to
the fact that Spring is only being used as a Dao implementation layer. I
came across the com.noelios.restlet.ext.spring.RestletFrameworkServlet
class. Based on its description it would appear this is what I should use to
properly set things up. Unfortunately I am getting crash errors when I try
and access my restlet app from a browser. I am hoping someone may be able to
shed some light on the situation.
The error I am getting is:
java.lang.IllegalArgumentException: Value does not implement specified type

Here is what my web.xml file looks like:

I also have a webservices-servlet.xml file for Spring bean definition. It
looks like:

Any ideas what the problem is?
