Interceptor to access session objects
Hello,
Which interceptor can I use to access session objects by putting them
as paramteres in struts.xml?
Many thanks,
J

Well, then I'd just use the ScopeInterceptor [1] to transfer arbitraty
action properties from one action to another via the session. Works
like a charm.

It will not work, I've been trying. There is a bug in
StaticParametersInterceptor, it will try to first put param on stack
(and for above example, it will throw an exception) and then it will
try to parse it.

I think, the best solution for you is just to write your own
interceptor that will do what you want and applicable interface.

Dave, ${#session.foo} works in struts.xml.

No. ScopedModelDriven, IIRC, will also only retrieve the "model" property; don't think it'll do arbitrary properties (could be wrong on that one, though).
You could try using an OGNL expression that references #session (like ${#session.foo}) but I don't know if that'll work. After trying it, it'd be nice if you reported back and/or added it to wiki (if it worked).

Well, an object from the session is to be retrieved from an action,
but I don't want to explicitly request the object from within the
action. I like it to be automatically set, using the getter/setter
methods in the action.
Can this be done with either SessionAware or through ActionContext?
Thanks,
J

I had a look at ScopedModelDrivenInterceptor but I didn't managed to
get it to work .There isn't much documentation on it or any examples
how the params are passed in the action :(

Take a look at the Scoped Model Driven

I found the last sentence difficult to parse.
What's your objection to ActionB retrieving the object via SessionAware (or through ActionContext)?

Basically I add objectXYZ to the session in actionA then the user
submits a query to ActionB. I want to retrieve objectXYZ from the
session without directly calling the a method on the session object
inside actionB in order to retrieve objectXYZ.
I looked at staticParameters and I can retrieve static param strings
set in struts.xml by only having getter and setter methods in an
action so I wanted to do something similar with dynamicly created
objects and referencing them in struts.xml

What, specifically, are you trying to accomplish?
