Ted Husted updated STR-2903:
----------------------------
Component: Extras
> MappingDispatchAction throws an error when mapping.getParameter returns null
> ----------------------------------------------------------------------------
>
> Key: STR-2903
> URL: http://issues.apache.org/struts/browse/STR-2903
> Project: Struts 1
> Type: Bug
> Components: Extras
> Versions: 1.2.9
> Environment: Windows/Tomcat
> Reporter: George Jempty
> Fix For: 1.3.5
> Attachments: MappingDispatchAction.patch.txt
>
> The JavaDoc for MappingDispatchAction states that unspecified() is the
> "method which is dispatched to when there is no value for the parameter in
> the ActionMapping." When I don't specify "parameter" in the ActionMapping
> however, I get the following stack trace:
> ERROR [http-8080-Processor24] (BaseCCAction.java:66) -
> DispatchMapping[/msalogin] does not define a handler property
> javax.servlet.ServletException: DispatchMapping[/msalogin] does not define a
> handler property
> at
> org.apache.struts.actions.DispatchAction.getParameter(DispatchAction.java:325)
> at
> org.apache.struts.actions.DispatchAction.execute(DispatchAction.java:170)
> at
> org.apache.struts.actions.MappingDispatchAction.execute(MappingDispatchAction.java:169)
> at
> com.cypresscare.web.common.actions.BaseCCAction.execute(BaseCCAction.java:60)
> at
> org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431)
> My investigation shows that this is due to MappingDispatchAction's execute()
> method doing nothing except delegating to DispatchAction's execute() method:
> public ActionForward execute(
> ActionMapping mapping,
> ActionForm form,
> HttpServletRequest request,
> HttpServletResponse response)
> throws Exception {
>
> // Use the overridden getMethodName.
> return super.execute(mapping, form, request, response);
> }
> Furthermore, as evident from my attached stack trace, it is the overridden
> getParameter() that actually needs to be used
> HTH
