I have two instances of Tomcat running on my server. I'm in the process of getting them to run as Windows Services (using the services.bat file in the bin - making sure the two service names are unique) and i'm getting stuck getting the second instance to work as it should (first one is fine). I'm getting the apache 404 error on the second instance when I browse to it. If I stop that windows service and start it up using "catalina start" from the command line, it works as it should. I know the service runs tomcat.exe - but i'm assuming catalina start runs the catalina.bat file? Does "catalina start" do anything additional to running the tomcat.exe file? If so, how do I start it up that way via a service? Thanks in advance!
