[S2] how to specify ActionMapper -- Restful2ActionMapper
I'm interested in using the Restful2ActionMapper, but I'm unclear
about how to specify it's usage.
1. I'm assuming that I'll need to modify the "struts.mapper.class"
struts property. Is that right?
2. In the struts-default.xml file that ships with Struts2, there's a
line, which names the class to "restful2":
<bean type="org.apache.struts2.dispatcher.mapper.ActionMapper"
name="restful2"
class="org.apache.struts2.dispatcher.mapper.Restful2ActionMapper" />
So, assuming that I need to modify the struts.mapper.class property,
which is right:
struts.mapper.class=restful2
or
struts.mapper.class=org.apache.struts2.dispatcher.mapper.Restful2ActionM
apper
3. On a side note, I'm looking for a little clarification on the ReST
conventions in S2. The ReST conventions specify some fringe HTTP
methods (DELETE, PUT) for invoking the "remove" and "create" methods
of an action. To work around the limitations of HTML, the docs say to
use the parameter "__http_method" in order to make it work.
Practically speaking, does this mean that I need a form field to do
this?
<s:hidden name="__http_method" value="'PUT'" />
If I understand correctly, will this form field invoke the "create"
method of my action?
Thanks!

Thanks Don, that's the clarification I was looking for.

Either is fine, but I'd recommend the first one. The second syntax is
more useful when you have your own class you want to use.

Yes, that's my understanding. I really like this action mapper, but
it does need some more thought as to exactly the best way to emulate
ReST in web applications, and better integration from the tag
libraries. The Ruby on Rails community has done some great work in
this area I think we can learn from.

You need to use the fully qualified classname.
So this should work:
struts.mapper.class=org.apache.struts2.dispatcher.mapper.Restful2ActionMapper
Not sure about the answer to question #3.
