I guess the real question is why you need access to TC's internals... I can't seem to understand it. The only example you provided was that you want to have instant access to sessions (does not require TC internals), you wanted to be able to 'touch' the session to update it's 'last access time' (not sure why you need that), and that you wanted access to the Realm. What are you actually doing with all those things?

It should be pretty much impossible if you yes, I noticed it's quite hard. That's why I suspected that was not the best way to proceed. The Valve solution works quite fine.

Re: How to get Request from RequestFacade
May I ask what exactly you want to do with the facade? Seems like you
could do what you want with a request or response wrapper instead.

but now, I cannot use the Facade to access the Request. How can I

Re: How to get Request from RequestFacade
That's the point, I don't know much about request/response wrapping.
I don't need the Facade itself, what I need are the real Catalina
Request/Response objects hidden behind it. I don't know how to get
them from inside a Filter.

Re: How to get Request from RequestFacade
Ok... do you need them to modify the request and/or response? Or are
you trying to pull some information from the original tomcat internals?
I first assumed you were attempting to modify the request or response,
so a wrapper is ideal. All you have to do is create a class that
extends HttpServletRequestWrapper or HttpServletResponseWrapper and
override the methods you want. Then in the filter, just instantiate
your request or response class with the original request or response in
the constructor. When you chain to the next filter, just pass on the
new request and response objects.

Re: How to get Request from RequestFacade
Don't know -- maybe one of the devs that monitor the list can offer some help. I'm still unclear as to why you need access those object. If you could say more about that, someone might be able to offer a better way to do what you want. --David Tremal Naik wrote: 2007/9/6, Tremal Naik [EMAIL PROTECTED]: ok, I don't need to modify the Request or Response.

2007/9/6, David Smith [EMAIL PROTECTED]: help. I'm still unclear as to why you need access those object. If you could say more about that, someone might be able to offer a better way to do what you want. ok, I need to access some of the Catalina Session specific features. In the Valve invoke() method I perform a call like the following: // update last access for this session Session catalinaSession = request.getSessionInternal(false); catalinaSession.access(); This is very easy to do with an HttpSession as well, but there are other things that come easy with Catalina objects and I'm not able to realise using J2EE specific interfaces, i.e.: // get all sessions active for this manager Session[] managedSessions = request.getContext().getManager().findSessions(); // find a session by ID Session session = request.getContext().getManager().findSession(id); // access the security realm Realm realm = request.getContext().getRealm(); Hence, I'd like to know if I can perform the above operations in a J2ee Filter doFilter() method.

From his examples below, it looks like he wants access to the TC internals.
For the OP's original problem, for obvious security reasons TC makes it very
hard to access the internal TC objects behind the various Facades from a
webapps code (e.g. a Filter). It should be pretty much impossible if you
are running in a sandbox with the default TC security settings. Overall, if
you really need access to the internal TC objects, IMHO you are better off
using a Valve, since the potential need to modify it when you upgrade TC
versions doesn't go away. If you can do what you need to do with the
operations and properties exposed via JMX on the Manager, then that is
probably cleanest. Otherwise, you would probably need to use introspection.
I first assumed you were attempting to modify the request or response, so
a wrapper is ideal. All you have to do is create a class that extends
HttpServletRequestWrapper or HttpServletResponseWrapper and override the
methods you want. Then in the filter, just instantiate your request or
response class with the original request or response in the constructor.
When you chain to the next filter, just pass on the new request and
