This is very helpful everyone. This kind of stuff needs to be in a newsletter or something, the part about using multiple jvms, and typical setups etc. Tomcat zip dir: C:\ApacheTomcat\apache-tomcat-6.0.26\bin In here I created a setenv.bat that has the following: set "CATALINA_BASE=%C:\Catalina_Base1%" C:\Catalina_Base1\ ** \conf ** \logs (automatically added when I ran C:\ApacheTomcat\apache-tomcat-6.0.26\bin\startup.bat) ** \webapps ** \work (automatically added when I ran C:\ApacheTomcat\apache-tomcat-6.0.26\bin\startup.bat) C:\Catalina_Base1\conf ** I copied the contents of \conf from C:\ApacheTomcat\apache-tomcat-6.0.26\conf ** I changed the shutdown port to 8006, HTTP port to 8081, and AJP Port to 8010 in server.xml C:\Catalina_Base1\webapps\ROOT ** I edited the index.html to indicate I'm using the html file from Catalina_Base1 http://localhost:8081 produces the edited index.html file from C:\Catalina_Base1\webapps\ROOT Very cool by the way. Ok, so how do I get specify multiple CATALINA_BASE options in the setenv.bat in C:\ApacheTomcat\apache-tomcat-6.0.26\bin ? This doesn't work: set "CATALINA_BASE=%C:\Catalina_Base1%;%C:\Catalina_Base2%;%C:\Catalina_Base3%"
