struts2 and WebSphere dynacache
Hi,
How do we cache struts2 actions using dynache? Since struts2 uses a filter
instead of servlets, the cachespec.xml entries I have for the actions don't
seem to have any effect.

There is no View action in Struts 2 by default, is it a custom action
you made? Anyway, if those are the static resources (like JS, Html
pages) you should server them as a static content. Struts 2 already
support that:

What if I use a servlet for the 'View' instead of using a struts2 action or
using spring/guice? Since my only objective is to try use dynacache, for
the views.
I don't have experience with Spring so my understanding of the benefits are
lacking.

Even then the solution is very limited. The OP probably wants to cache all
popular pages/reports, in many cases the same action will be responsible...
a singleton clearly can't address that.
It could be addressed with an object pool that was keyed to actions,
parameters and values and managed by an interceptor. I think it would be
tricky to implement, particularly the promotion of which resources to the
cache and which objects to dispose of.

It isn't a good practise to declare actions as singleton, Struts 2
wasn't designed in that way. You really must know what are you doing
:-)

Assuming that caching of Action objects makes sense in your application,
you could change the struts default object factory,
to guice or spring and declare the action beans that you want to be cached
as singletons. Alternatively you could write your own object factory and
put some caching logic there.

Hi,
Thanks for the quick response. I've structured my struts2 application by
using a struts action 'View' which renders different pages depending on the
parameters passed in to the view. So I'm looking to cache the different
pages based on the url.

Why and what for? Actions are dynamic elements of your application and
caching them doesn't make sense.
