I have been told to update some application from Spring 2.0.8 to Spring 2.5.5. This application is using Struts 1.2.7. Once I change the Spring.jar I get the following exception while loading in JBoss 4.0.5:

10:14:57,579 ERROR [[/PortalRRHH]] Servlet /PortalRRHH threw load() exception
javax.servlet.UnavailableException: org.springframework.web.struts.DelegatingTilesRequestProcessor

This is defined in the struts-config.xml this way:

<controller locale="true">
  <set-property property="processorClass" value="org.springframework.web.struts.DelegatingTilesRequestProcessor"/>
 </controller>

I have no clue of what is happening since it works with the old version of Spring and the DelegatingTilesRequestProcessor is still available in Spring 2.5.5. I have no previous experience with Struts so if you need anything else to figure what the problem is please ask and I will update the question.

Thanks.
