Hi there,

i have a Problem with a class which could not be found. Ive included spring-webmvc via Maven Dependencies in Version 3.1.3.RELEASE. Iam trying to use Tiles 2 with Spring 3. Ive configured Spring as written in the documentation. The Project compiles without errors but when i run it, it throws always the following errors:

Code:
type Exception report

message Servlet.init() for servlet dispatcher threw exception

description The server encountered an internal error that prevented it from fulfilling this request.
