I think what you're looking for is a more flexible Mapping which can be achieved via Spring
http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/servlet/DispatcherServlet.html which would enable you to define your own DefaultAnnotationHandlerMapping http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/servlet/mvc/annotation/DefaultAnnotationHandlerMapping.html <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"> <property name="interceptors"> ... </property> </bean>If your annotated class is a Web Controller then you can use Controller.htm http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/stereotype/Controller.html//Once your spring framework is achieved you can implement RequestMapping http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/web/bind/annotation/RequestMapping.html where Annotation for mapping web requests onto specific handler classes and/or handler methods. Provides consistent style between Servlet and Portlet environments, with the semantics adapting to the concrete environment. so as you can see there is alot of flexibility with Handlers,Annotations and Controller available with Spring Martin ______________________________________________ Disclaimer and Confidentiality/Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité This message is confidential.

While this is not a bigger issue > for the simple example as above, it can be awkward for little more complex > domain models. What suits better for those domain models is to have a > builder, which has setters for all the parameters on the form and has > responsibility to build the actual domain model objects.
