Hello, I would like to run multiple instances of tomcat services. In fact one by web site to avoid to disturb other developments on separate web site. I am using IIS and I am wondering how to configure server.xml, wrapper.properties files and IIS to be able to run the complete configuration. When I am using one instance of tomcat it works properly but when I try to start two, the IIS web site says that he didn't receive any response from tomcat. I am pretty sure that the HTTP port has to be different but I am using 2 differents IP address and then why is it necessary to specify the different ports maybe have you some examples of configuration, it will be helpfull. Thank you very much Frédéric Vanclef
