Extend HttpHeaderResult to support HttpServletResponse.sendError()
------------------------------------------------------------------
Key: WW-1853
URL: https://issues.apache.org/struts/browse/WW-1853
Project: Struts 2
Issue Type: Improvement
Components: Dispatch
Affects Versions: 2.0.7, 2.0.6
Reporter: Jasper Rosenberg
I had a need to have an action return a 404. To do this, I extended the
HttpHeaderResult class to accept an optional "errorCode" parameter which, if
present, would trigger a response.sendError(errorCode).
Attached is my extension, but it probably should either be broken into its own
result class, or properly merged into HttpHeaderResult itself. Also, support
should probably be added for an optional "errorMessage" so
response.sendError(errorCode, errorMessage) can be invoked instead if an error
message is available.
Here is a sample usage:
<package name="default" extends="struts-default">
<result-types>
<result-type name="httperror"
class="com.mycompany.struts2.result.ErrorSupportingHttpHeaderResult"/>
</result-types>
<global-results>
<!-- 404 page result: not found. -->
<result name="404" type="httperror">
<param name="errorCode">404</param>
</result>
</global-results>
</package>
Now I can have any action return "404" as the result and I will get a 404 page.
