Hi, you indeed didn't the question :-) (but still, thanks for answering!)
The problem is as follows:
I'm making a plugin which puts a wrapper around the request of a servlet.
A servlet gets invoked by: doGet(HttpServletRequest request, HttpServletResponse response)
What I want to do now is to put a filter in front of it. When a request comes in,
the filter does:
newrequest= new RequestWrapper(request);
chain.doFilter(newrequest, response);
That way the servlet is invoked with a wrapper around the request. Until now, this approach works.
Now comes the problem:
the filter also does some other things than creating the wrapper. That way it always has to be called, before a servlet is called.
The filter I have now, always get called when there is an incoming request. But when a servlet uses a requestdispatcher to include another servlet, the filter doesn't get called.
In a little schema:
Without filter the call looks like:
Request --> Servlet1 --> Servlet2 (so servlet1 uses a requestdispatcher to include servlet2)
If you add a filter to this you get:
Request --> Filter -> Servlet1 -> Servlet2
But what I need to get is: Request --> Filter -> Servlet1 -> Filter -> Servlet2
