I think, that in the beginners article it has to be noted, that servlet request, passed to further chain, has to be wrapped.
For me, the Java beginner, it took some time to understand, why the templated RequestDump filter doesn't work. It became clear, that the getParameter function is destructive for ServletInputStream, and ServletRequest object has to be reconstructed for further use.
