There have been a bunch of session-related fixes since 5.5.25 that may be affecting you. Try searching http://tomcat.apache.org/tomcat-5.5-doc/changelog.html for "session" until you get back to 5.5.25 and you can see which issues were fixed in each release. Is it possible for you to upgrade to 5.5.28? Also, that IllegalStateException looks more like a problem with the JSP (that is, creating a session too late) than the rest of the server. It looks like this is happening in a JSP called unhandledException.jsp, which presumably if an error handler. If the servlet/JSP that was running prior to the exception being thrown didn't require a session, it's possible that none was ever created. If the servlet/JSP emitted enough output back to the client that the output buffer was filled and flushed, then the response is "committed" which means that all headers have gone to the client and you can't add more. When the exception occurs, your unhandledException.jsp tries to create a session, which requires a header to be added to the response, which fails because the headers are long gone. If this sounds plausible, check to see if you really need session access in unhandledException.jsp. IF not, simply add session="false" to your <%...@page> header in the JSP and it might fix everything up. - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAktsQZEACgkQ9CaO5/Lv0PD5HQCfa0lbEp1ecvn7JtJ6oHYbgHYA Sl8AoJ7NWoh0yxhKrJbe4IducCTKH1BM =MdK+ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
