Return types from execute() method in struts2 action

[Souvvik Basu]

Hi,
I have been trying to learn Struts 2 through materials available on the net. One thing I just picked up is that there are 5 different return values from the action's execute() method, that are pre-defined in the framework, namely SUCCESS, ERROR, INPUT, LOGIN, NONE.
What I have a doubt about is...we can always set our own return value in the struts.xml file, in the action element. I can obviously do something like the following

<action name="Register" class="manning.chapterThree.Register">
			<result>/chapterThree/RegistrationSuccess.jsp</result>
			<result name="reallycoolresult">/chapterThree/Registration.jsp</result>
		</action>

and then make the execute() method return "reallycoolresult".

Can't I?
If I can't, then please tell me where my understanding went wrong. If I can, then what's the point of having pre-defined return values?

Please help me clear this confusion.

yes, you can do that.

If I can, then what's the point/advantage of having pre-defined return types?

[Jesus Mireles]

I'm sure those are predefined because the majority of people use things like success, error, input, none, login.

The fact that you can return any other doesnt matter, the point is the method still returns a string ... you map that string to some result name ...

Hi,
I tried returning custom values from my execute method, but it was always returning error and the custom value was ignored.The page corresponding to "error" return value was called.

@Above Cause your method returning error somewhere you are getting exception fix the problem.
