action mapping input

["Chen, Gin" <Gi...@tvratings.com>]

Hi all,
	I'm still new to struts and I cant find this in the documentation
but, lets say that you have one of the struts-config from the docs.

  <global-forwards type="org.apache.struts.action.ActionForward"/>
    <forward name="logon" path="/logon.jsp" redirect="false" />
  </global-forwards>
  <action-mappings>
    <action path="/logon" type="org.apache.struts.example.LogonAction"
name="logonForm" scope="request" input="/logon.jsp" unknown="false"
validate="true" />
  </action-mappings>

   Rather than have input="/logon.jsp" as in the snip can you have
input="logon" and have it use the path from the global-forwards?
   It just seems like it would make more sense since that means that you
only have to change one location in case the location of the file ever has
to change.

Thanks,
-Tim

... and now that we have the JSTL you can have your tags optimized into 
actual code.  It's my understanding, for example, that a forEach tag 
would be translated into an actual while (or was it for ...  anyway, you 
get the point).  So, you're bypassing the tag-usage overhead some.

Hopefully Martin will see this and elaborate (and correct me if I'm 
wrong).  I believe that's fairly close though ...

Of course - not all of us are on containers that even support the JSTL 
... but some of us are :-)

You can also leverage the input attribute in an action by returning the 
following from perform/execute:

new ActionForward(mapping.getInput())

The input attribute is used when validation of the form bean fails. if 
the validation in the form bean (or the validator) fails the action is 
never run so it couldn't use the forward. The controller is returning 
you to the input page.

If a validation in the action fails (like a business logic failure)then 
you can use a "failure" forward.
