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 > 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. > <Executor name="mySiteThreadPool" namePrefix="catalina-exec-" See namePrefix comment above. > <Host name="localhost" appBase="webapps" See appBase comment above. > <Context path="" docBase="appMainUserSite" /> See <Context> comment above. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
