Re: Are many people running Tomcat 4 in standalone mode?
I have been running Tomcat 3.2.x standalone on Windows NT for about six months and have never had a problem. Our applications are totally dynamic except for a few image files, so I don't think Apache would help. As far as reliability goes, at least on NT, it seems that using both Apache and Tomcat together is less reliable as there is one more thing to go wrong. We have another server running this combination, and it has had to be restarted at least twice, whereas the standalone just works. (of course it could have been an NT problem ...) As far as ease of use, count how many questions on this list are about configuring Tomcat with Apache :-) Hope this helps, Jim --- Jonathan Eric Miller [EMAIL PROTECTED] wrote: I'm curious to know if there are a lot of people out there running Tomcat in standalone mode versus using it with Apache Web Server or some other Web server? Previously, I've been using it with Apache Web server on Solaris 8 with mod_jk. However, as of version 4, it seems like it's pretty stable and it seems to be getting sufficiently robust. So, I'm planning on running it in standalone mode. Everything seems to be working fine. I'm wondering if using it with Apache Web Server really makes that much difference in terms of performance? My Web application isn't taking a massive amount of hits, so, I think I should be OK. I was just curious what others are doing. Jon __ Do You Yahoo!?

Re: Servlet Runs SLow
I copied the html into a static file and was able to bring it up
immediately in Netscape 4.76, so it doesn't appear to be the contents
of the form that is the problem.
Does it take a long time to display, or does it just not appear to
finish loading? I have also noticed that sometimes even after the page
has loaded, Netscape still appears to be working. So far, I have just
ignored it.

Re: Servlet Runs SLow
Sorry, I'm out of ideas. The servlets I'm working on work fine in both
Netscape and IE. You may want to try to collect some more information
(log begin/end times in the servlet, use a network monitor to see what
is happening, try different Netscape settings) and see if anything
unusual is happening.

Re: How to execute a dynamic JSP from a Servlet WITHOUT sending it to disk first ?
Fernando, Why do you need to create the JSP page itself dynamically? Couldn't you just create one or several JSP pages, then in your servlet, get the data, put it into request attributes, and call the proper JSP page to display the data? The JSP page would then take the data from the request attributes and display what is needed.
