action mappings help

I'm using struts 2.0.9.
Where do i read about action mappings and how to configure them?
Is there any detailed documentation? Right now i'm doing something like 
this...but i don't really know why i need the result name="input" tag 
and couldn't find any info about it on my own:
        <action name="prepvendor" class="addPoAction"
            method="prepVendor">
            <result>/popages/selvendor.jsp</result>
            <result name="input">/popages/selvendor.jsp</result>
        </action>


thanks

In the Struts2 documentation of course ;-) These pointers may help:

http://struts.apache.org/2.x/docs/action-configuration.html
http://struts.apache.org/2.x/docs/result-types.html

You need a result named 'input' in at least the following situations:

* you return 'input' as the result from your action method ;-)

* you're using validation and validation fails; Struts will 
automatically forward to the 'input' result so the user can correct the 
data they entered and re-submit

* the same may also be true for conversion errors

In general, for an action mapping that is going to retrieve data or just 
display a page or form, you don't need an input result, and when you do 
use an input result it should generally be pointing at such a mapping.
