Subject Re: problem with filters on Tomcat 7.0.16 and above
Date Sun, 26 Aug 2012 20:27:09 GMT
I have found, where is the problem.

problem is in in

    public final void invoke(Request request, Response response)
        throws IOException, ServletException {


// Select the Wrapper to be used for this Request
        Wrapper wrapper = request.getWrapper();
        if (wrapper == null || wrapper.isUnavailable()) {

if request is : http://localhost:8080/app/index.html (direct link to
Spring MVC controller), object wrapper is not null,

and if request is : http://localhost:8080/app/invitations/ (served by
UrlRewrite filter), object wrapper is NULL!

in on line 649:

request.setWrapper((Wrapper) request.getMappingData().wrapper);

is set NULL.
