Multiple Actions for a single page. Is this possible
hi,
We have two pages a.jsp and b.jsp developed with the action class mehods
Ac.a() & Ac.b() that render these pages. Now we need to develop a new page
c.jsp which is combination of both a & b.jsps.
i can include the jsps into the c.jsp. But what abt the action class behind?
can they not get automatically invoked and the pages get populated? More
over i have some logic to be performed based on the inputs made in the two
sections of c.jsp. Is it possible for me to only do this part as a layer?
any ideas as how to go abt this? pl help.
regards,
ravi

By chaining several actions together. All of the getters inside those
actions are availible to the resulting .jsp/vm/or ftl.
I have used chain in cases where I had a more generic action that supplied
values for picklists and I needed those values supplied to several pages.
The action definitions were configured to include that more generic action
for the picklists. That is just one use case though. The above could be
solved via inheritance as well, that has its own side effects.
In the end are you trying to do a more wizard multi/step solution?

hi,
We have a form in c.jsp which by some event makes an ajax call fetching
b.jsp, a.jsp and rendering it. Now the requirement is that
(1) i want to get this b.jsp by calling some other action class.
(2) Once its rendered and i submit the page c.jsp the consecutive action
class should be able to get all the entries made even in the b.jsp & a.jsp
(obtained by ajax call)
i am not sure how action chanining/ s:action can help me.
any hlep / pointers?
regards,
ravi

chaining is one way to accomplish this.

Check out the <s:action /> tag, when c.jsp is rendered you can place
actions on it. All the stuff including interceptors will be invoked
for each action by creating a new action proxy. Don't forget to set
executeResult="true" so the output gets' rendered.
The surrounding action (if c.jsp is an action result) will still be on
the stack.
Cheers,
-Ralf
