Do i need an Apache/Tomcat server for a code program that needs the client to establish connection with the server & depending on what user does thereafter ,it updates the desktop of the client periodically i.e sends new desktop images to the client...now am i in need of an Apache/Tomcat server installation, if i want to run this code from the same system .... :confused:

you need apache/tomcat to host the jsp page you want to run. if you're not running jsp, you need whatever server installed on the server machine to host the type of page you're running. you do not need the server installed on the client machine that you are requesting the page from. you do need, however, to reference some of the same libraries, so that you can commit web requests from your application.
