Without large changes it isn't possible to change interceptor stack at
runtime, it should be only possible to create a new stack with
PackageProvider

If just want to detect a jar on classpath take a look on LoggerFactory
- it detects different loggers based on ClassNotFoundException ;-)

You can always @Inject Configuration and traverse over it, anyway
without large changes inside S2 it isn't possible to simple inject
interceptor. I think the simplest option is to mark action with
interface to activate given interceptor. In the same way as
ServletConfigInterceptor injects request (RequestAware), session
(SessionAware) and so on.

ActionInvocation.getStack () does not give the interceptor stack, at
least that's what I think
I want to know the stack to insert an interceptor to the execution of
actions using particular stack.

Re: dynamic interceptor insertion
Posted by Gildas de Cadoudal <gi...@gmail.com>.
I look towards the ActionInvocation or ActionProxyFactory but the
problem with this solution is that we do not know what Stack is
executed.
I also look towards a placeholder, but the problem is the same as previously.
To clarify, my need: I want to allow the inclusion of a library in the
classpath enable features brought by it without changing the
configuration of the main project.
I hope you understand, because I know that my English is very bad (I'm french)

What would be useful, if you could have a place holder in the interceptor
stack and then inject the interceptor element you need on the action?
Copying the whole lot each time makes a lot more maintenance and more prone
to errors.

Most of the time, if not 99% of the time, all I want to do is add an
interceptor before or after some known interceptor. As I've gone on record
before, I want this feature too :-)

Re: dynamic interceptor insertion

Thank you Lukasz I'll put it on my todo list ;)
Martin, interceptor stacks are efficient I think the scope struts2 has is
very good, still it is fun to push boundaries, one of those fun higher
initiatives would be a Web IDE for struts2. You could dynamically build an
interceptor stack, and you could step though the stack keeping an eye on
the action as part of the debug process, (values before and after
interceptor)...
So in short no there isn't anything that can't be done with non dynamic
stacks, but in the name of learning this web framework and making things
more efficient- being able to dynamically alter the stacks is very
interesting. At the end the the day the idea was to write out a non-dynamic
struts.xml for production deployment.

Hm... yeah, with custom ActionInvocation and ActionProxyFactory should
do the trick, check the REST Plugin to see what must be implemented to
create your own ActionInvocation

This is somethings I've wanted to do (dynamically change the interceptor
stack), I'm not at a development machine so have not checked the
plausibility of the following but would like input:
Is it possible to create a custom ActionInvocation object, for this purpose?
Is it possible to essentially recreate the functionality of
ActionInvocation within an interceptor which then delegates to other
interceptors?
