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
Versions: 1.2.9
Environment: Windows/Tomcat
Reporter: George Jempty
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

org.apache.struts.actions.DispatchAction.getParameter(DispatchAction.java:325)

org.apache.struts.actions.DispatchAction.execute(DispatchAction.java:170)

org.apache.struts.actions.MappingDispatchAction.execute(MappingDispatchAction.java:169)

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
