As you might guess, when the JSP rendering is in progress, the HTTP
headers are already rendered ("on the net"), so they can't be modified
by the server anymore. Thus, an embedded action invoked by <s:action
/> cannot send a redirect- or action-redirect-result.
Please tell us exactly what you want to do, as there might be a
simpler solution to your problem.
As your workaround seems to be to "invoke back" actionA from your
example, I guess there's another result for actionA which then renders
the data which results from actionB into the page. This can either be
done using the action chaining (which seems to be discouraged as I've
learned from this maling list) where you don't have to invoke the
action from the JSP but as a result directly, or simply render the
data inside the action tag, doing something like this:
| <s:action namespace="/foo" name="bar" executeResult="false">
| <s:property value="myPropertyFromTheBarActionImplementation" />
| </s:action>
This works because the action tag does not execute the "usual" action
result from the mapping, but rather pushes the action object (and IIRC
the model, if you use ModelDriven) onto the stack, and then evaluates
the action tag body.
Cheers,
