spiker updated WW-2991:

    Attachment: diff_to_2_1_6.txt
                ConventionUnknownHandler.java

This is my work on this issue except the full-action-name-based result.

And I found xwork did not cache returned results and actions. I need to implement some unknown-result cache and unknown-action cache to improve performance.

> More intelligent result mapping.

> More intelligent result mapping could make Convention plugin more conventional. Here was my some initial thought:
> In my personal experience, most of the time, logical result name was not necessary.
> If the result string was "create.jsp", it will be dispatch to "create.jsp" under same package in "/WEB-INF/content". No need to look up "create.vm" or other  guess work, performance will also increase. 
> If the result string was "/login.jsp", it will be dispatch to "/WEB-INF/content/login.jsp" .
> If the result string was "redirect:create.jsp", then change result type to "redirect".
> If the result string was "edit.action", it will be chained to "EditAction" under same namespace.
> If the result string was SomeOtherAction.class.toString(), it will be chained to the SomeOtherAction.
> To change default result type of action from chain to other result type, just prepend result type in result string, for example: "redirect:edit.action".
