I have problems: I have a GlassFish server configured in Eclipse. Now I need to add the project to its class path: I go to Run Configurations -> Glassfish -> "Glassfish 3.1.2 on localhost" (current server). Now, as you can see from the attached image, I cannot select any server, since there is no server in the drop-down menu.

I would like to select a server and then go to "Classpath" and add a project ... Can anyone help me?
It seems strange to me that when I launch my web application, it runs on this server ... So why can't I see it in Run Configuration?
Thanks to everyone who can help,
