Re: Gotta Be Something Simple

I have a couple of servlets that after I corrected the CLASSPATH, compiled without any problems. However, the page that attempts to invoke the servlets returns a 404 (not found). I've tried putting the servlets in various directories under my tomcat directory tree, but still same result. Both servlets are part of the same package. The page that tries to invoke the main servlet uses a form action=servlets/servletname. This is my first attempt in writing something like this, and even though I think I understand where things are supposed to go and why they are supposed to go there, I am baffled at why the servlet can't be found.

Re: how to deploy Out-of-process servlet containers
mok_jk for Tomcat 3.x mod_webapp for Tomcat 4.x Out of process means that the servlet container and the web server run in different processes and a mod is used to relay information between the two. Stand-alone means that Tomcat servers both the static (html, images, etc) AND processes the serverside java of servlets and jsp. In process is when the workers for Tomcat actually reside within the webserver's process. There may be someone who can make more sense than me or correct me if I'm wrong, but that's the way I understand it. If you read the doc's they explain it quite well.

fault tolerance tomcat4
I am hosting several sites on a Solaris 8 SPARC box. I would like to use tomcat4 b6+ to take care of all my serving. I've load tested it using JMeter and it performs more than admirably for my uses.

How to alias 8080
I could be wrong on this, but I think you could use the Listen and Bind directives in apache's httpd.conf to bind it to individual ip addresses, and in tomcat 4 you can use the address parameter in the service decriptor. Basically they would be on the same port, but different ip addresses. Matt
load balanced workers
I'm trying to implement load balanced workers in the form of 2 different jvm instances on a single physical server. I have 3 workers in my workers.properties file : workers.list = ajp12, ajp13, backup ajp13 = first instance ajp12 = first instance backup = second instance lb.loadbalancer.balanced_workers = ajp13, ajp12, backup in my httpd.conf file I have tried two different things... if I set JkMount to ajp13, and then stop the instance that worker is in, then the site fails, I would think it should switch over to the backup worker. Should I instead be putting lb in my httpd.conf? If that is the case wouldn't I need to include lb in the workers.list property? Matt

Re: how to let two user stop and start tomcat
This is because when you are trying to load the second instance of Tomcat it is using the same server.xml file. As a result when the second instance starts it has an error because the first one has already bound the ports it uses (8080, 8007, 8009, etc) so they are unavaible to the second instance. You need a second server.xml file for the second instance and refer to it as an argument when starting the second instance.

Re: exhausting connections under load
Taking a stab in the dark this is probably for a few reasons. The first that comes to mind is that Tomcat 3.2.x is not HTTP 1.1 compatible, so for each object in a web page it creates a new connection...not very efficient. Its really meant to be put behind Apache I think. The http serving abilities are usually used just for quick/easy development purposes, not production delivery.

No errors, no warnings, its terminal window just vanishes. I tried increasing the heap size, but that didn't seem to help. Next I tried installing PoolMan 1.4.1. This doesn't crash TomCat but mysteriously it can't find its poolman.props file. I've tried putting it in directories that I'm absolutely positive are in my ClassPath without luck. I've read the docs pretty extensively I think, but can't seem to come up with an answer. My overall goal is to simply add connection pooling to tomcat. If anyone can give me some pointers, thanks in advance. Matt
