Convention Plugin and Method Called In Action Class
I'm learning to use the Convention Plugin.
I understand from the excellent notes posted on the Wiki
(http://cwiki.apache.org/WW/convention-plugin.html) that the plugin finds
the Action classes and maps those action classes to Action names and results
to specific JSPs. For example:
Action Class -> Action URL -> View
com.example.actions.MainAction -> /main -> /WEB-INF/content/main-success.jsp
What I'm not clear on is what method is called in the Action Class. Is it
always the execute method? Is there a way in the Action URL to specify
which method to call?
I know that I could use Struts 2 @Action annotation to map a method to an
Action URL, but I'm wondering if there is a way to call a specific method in
the Action class using just the Convention plugin and no annotations.
Thanks for the help.
Bruce

Hi all,
in my apps i use only convention to manage action configuration,
and also i make use of addresses like:
myapp/myaction!input
they work for 2.1.6.
I don't know if convention has anything to do with it,
but to be sure You can use config browser plugin to see how things are mapped.
Best greetings,
Paweł Wielgus.

I thought that was the case. One of the references I'm using for the
Convention plugin is the MEAP draft of Struts 2 in Practice (was sorry to
learn that the book isn't being finished, the first few chapters were
excellent).
Using the bang (!) operator doesn't work with the Convention plugin.
Oh well onto learning the Struts 2 annotations.
Thanks for the information.
__________________________________________
It is going to default to the 'public String execute()' method. It
might be possible to use the exclamation point to try to get the
plugin to call a specific method ->
http://localhost:8080/app/action!differentMethod
Really though, this goes against the notion of 'conventions over
configuration.' The @Action annotation would be a much more
maintainable way to handle this sort of thing.

You just did... The next one will cost you $1 (just kidding), but for
your next question, you'd be better off sending a separate email (not
a reply to an existing message) so people won't consider your message
to be thread-jacking.

It is going to default to the 'public String execute()' method. It
might be possible to use the exclamation point to try to get the

Really though, this goes against the notion of 'conventions over
