There are several things that could be happening: 1. There is a self-call in ApplicationHttpRequest.getSession / HttpServletRequestWrapper.getSession 2. You have wrapped a session with itself 3. You have a huge number of server-side forwards that all wrap the request, so you get a very deep stack when trying to actually get the original request 4. You have an error in an error page so it continuously forwards to itself #1 is probably not the case. #2 and #3 and #4 are much more likely. Let's look at the rest of the stack trace to see how deep we are in other things: > org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913) > > [...] > org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:302) There's > a forward.

You didn't post the whole stack trace, but I'm guessing that at some point, you got back to the real Tomcat code that originally processes the request that then gets looped. Given the above stack trace, I would say that you either have a server-side forward that is out of control (forwarding to itself over and over again) or you have an error page that is causing an error (which is really a special case of the first case). Time to take a look at the URLs that are being requested during those forwards. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk53m0YACgkQ9CaO5/Lv0PD/xQCguxdgJWgBirLVKb2+wnIja6o6 t+AAoIJdojq5Onqi/zOgpp5Ex8dmlTNe =c2tW -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
