U are right, It is RAD 6.0. I tried to select the server to run my application. There are 2 options Server and Server Project.
I am adding my WEB project to the Server and when I am starting it, it says that the runtime environment is not configured and gives the path of my installation directory.. and says the server is already started..I
There's only one server. Go to the J2EE perspective, right click the server and start it. You can add your application to the server by right clicking the server and adding the application or right clicking the project and selecting "run on server." I'm not sure if either of these works for war files or if you need an ear though.
