Although I consider very good what Christian said, sometimes the
client-side is not an option (f.i. you don't want to send the same amount
of data on mobile devices).
Conversely, sometimes the server-side could not be an option (f.i. you
might choose an not-intrusive way for your code, you can choose to write
every view logic on top your existing code).
Speaking of server-side, and especially regarding Struts, this is what I
usually do:
* I wrote an interceptor which being based on the agent parameter, put a
variable in the value stack context.
* the value of this var is used as the result folder (f.ex.
<result>/WEB-INF/${VIEW}/YOUR_PATH</result>). This allows you to define a
kind of hierarchy writing a specific result only for those you really want
to overwrite
* on top of that I setup sitemesh (with its filter properly placed in terms
of ordering) which decorates the jsp depending on the path
(/WEB-INF/mobile/a.jsp uses a different decorator from
/WEB-INF/tablet/a.jsp)
* the same interceptor I checks if the action implements ViewAware
interface and eventually injects the view name inside the action itself.
I preferred this approach against the result decoupling, because I don't
want to start using a lot of wildcard.
The only drawback (if it is one) I noticed until now is that IntelliJ Idea
doesn't allow me to navigate result location by click.
My 2 cents too.
