Tomcat Configuration Help
Hello, I'm totally new to Tomcat and I have been searching the net for a little while now looking for info on configuring tomcat to host multiple apps on different ports and different web roots. I have come across some posts on running multiple instances which might be the right thing for me I'm still not sure. So here is what I'm looking to configure, I just dont know if it's the right way. tomcat - webapps -- appWebServices -- appMainUserSite I would like to run the app appWebServices on port 3100 with the docBase to be tomcat/webapps/appWebServices. I would also like the app to support 500 simultaneous connections. Now I would like to run the app appMainUserSite on port 3200 with the docBase to be tomcat/webapps/appMainUserSite. I would also like the app to support 100 simultaneous connections. Now this configuration seems to work, but since I'm fairly new to this I thought I would get a second third opinion. So is what I'm doing the right solution or is there a better one, like multiple instances etc. Thanks, tom server.xml Server port=8005 shutdown=SHUTDOWN ...

Other than not telling us the Tomcat version you're using (along with the JVM and platform), you've done a pretty good job of explaining the situation. If you don't need to isolate the applications by port (that's quite unusual), you can simplify things a bit by using virtual hosting: http://tomcat.apache.org/tomcat-6.0-doc/virtual-hosting-howto.html http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts I have come across some posts on running multiple instances which might be the right thing for me I'm still not sure. Multiple instances are not strictly necessary, but might be easier to administer, and will obviously avoid undesired interaction between the two webapps. tomcat - webapps -- appWebServices -- appMainUserSite That's not good. Each Host should have its own appBase; by sharing them, you've made both apps available on both hosts. I would like to run the app appWebServices on port 3100 with the docBase to be tomcat/webapps/appWebServices. I would also like the app to support 500 simultaneous connections. Now I would like to run the app appMainUserSite on port 3200 with the docBase to be tomcat/webapps/appMainUserSite. I would also like the app to support 100 simultaneous connections. As you surmised, you will need separate Service elements if you want to segregate the apps by port number. Executor name=tomcatThreadPool namePrefix=catalina-exec- You might want to use a unique namePrefix for each Executor so you can more easily tell them apart in a thread dump (should that ever be necessary). Connector executor=tomcatThreadPool port=3100 redirectPort=3144 If you don't have a Connector for port 3144, why do have a redirectPort? Also be aware that many versions of IE don't handle HTTPS over anything other than port 443. Host name=localhost appBase=webapps The appBase should be unique for each Host. Context path= docBase=appWebServices/ This is bad; do not put Context elements in server.xml. Your webapp should be located in this Host's appBase directory, and named ROOT (case-sensitive, even on Windows). What you have now got you double deployment, once as the default webapp and once more as appWebServices - confusing at best. The Context element, if you need one at all - and you don't, in this situation - should be in the webapp's META-INF/context.xml file, in other words: [appBase]/ROOT/META-INF/context.xml and must not include path or docBase attributes.

Re: Tomcat Configuration Help
Chuck, this is great thanks. OK, I'll fill in some of the gaps here I'm running Tomcat 6.0.26, planning on upgrading to 6.0.29 shortly. Im using Java 6 on Mac OS X server. So I have one question, on your comments on Context elements in server.xml. I put the Context element in so that I could set the docBase to my app directory thus avoiding the need to append appWebServices to the URL (e.g. http://mysite:3100/ vs. http://mysite:3100/appWebServices). Is there a better way to do this?

Re: Tomcat Configuration Help
Chuck, thanks! I have been missing the obvious. I'm not sure how I've missed that for this long. ROOT is the required name for the default webapp for a Host. I have it working per your suggestions and guidance, thanks a bunch.
