Description

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
