Tomcat Performance Concerns

I have a simple JSP-application that makes use of an ODBC database (access). When I run it using Tomcat on PC2 (XP) its performance is very good. However, running on PC1 (W2K Server) is orders of magnitudes slower! :-( I have already read most of the relevant manuals and tried various settings

Reloading JAAS Configuration File

Hi all, I was wondering if there is a smarter way to reload a jaas configuration file than to call Configuration.getConfiguration().refresh(); in a servlet. I was thinking of such a call in a webapp lifcycle listener. I really don't know much about JMX but perhaps it should the only nice way?

Re: problems with connector

Hi Enrico, it looks like the config you sent doesn't fit to your problem. The only configured forwarding rule with JkMount is a comment, so mod_jk should never try to reach any tomcat. I assume, you added the comment sign when trying to find the reason to your problem, but this makes me question

If your JSP page is being included from another servlet, then it won't be allowed to set the content-type (or charset) of the response. Just a wild guess here :). The HTTP/1.1 RFC states that the character encoding of the headers is iso-8859-1. That is why Tomcat doesn't provide an option to
