Bugzilla is not a support forum. Plese post your questions to the Tomcat users list, or the Apache Web Server users list. To subscribe, send mail to users-subscribe@tomcat.apache.org or users-subscribe@httpd.apache.org Nevertheless here are some remarks that might be helpful. Please don't answer here but take the discussion to one of the lists. > It works ALMOST ok but when I hit ANY exception, for ex, > java.lang.NullPointerException, http doesn't reponse anymore.
