Hi Mark, thanks for the reply. I've modified https://github.com/paul-hammant/servletDispatcherTest to include scripts to reproduce the problem, and to show the two web-apps working separately, but not in the getRequestDispatcher(..).include(..) way.
The scripts download an anointed version of Tomcat7, add the crossContext="true" attr to context.xml, and even copy the war files into the webapps/ folder. In the README.md, which Github kindly renders into HTML on the front page of the project, there's instructions to build/deploy, as well as what URLs to click on to see the problem, as I see it. There are now three servlet-filters activated for different urls: /a/IOutputMyThreadID (class of same name) /a/AIncludingContentFromB (class of same name, extends IOutputMyThreadID) /b/IAlsoOutputMyThreadID (class of same name) - Paul On Mon, Jul 1, 2013 at 2:34 PM, Mark Thomas <ma...@apache.org> wrote: > On 29/06/2013 13:51, Paul Hammant wrote: > > If you edit conf/context.xml and add crossContext="true", one Tomcat > > mounted web-app should be able to forward to (or include content from) > > another in the same request. > > > > I can't get it working and I have a minimal Github project ( > > https://github.com/paul-hammant/servletDispatcherTest) that shows how > far I > > got.
