The "code server" should be the machine where you run the DevMode, so if you run your browser on the same machine as the DevMode, it should just be "localhost" (only if you run DevMode on a machine and the browser on another one, or in a virtual machine, then you'll use the name of the machine running DevMode, so that the browser will be able to connect to it). The startupUrl should be the one of the Glassfish server. The "remote UI" is Eclipse itself: DevMode runs a distinct java application and either uses a Swing UI or connects to a "remote UI" (to tell you which URL to open, to output logs, etc.) When using the GPE, the "remote UI" is the "Development Mode" view in your Eclipse (where you can then stop the DevMode, refresh the server code, and see the logs).
So, in your Eclipse launch configuration, you should have: -startupUrl http://externalServer:8085/MyApp/MyApp.html → corresponds to the URL field in the GWT tab -noserver → because you unchecked "Run built-in server" in the Server tab -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" → the GPE adds it by default, do not change it (or remove it to use the Swing UI rather than using the integration within Eclipse) The GPE also adds -codeServerPort 9997 but that's not really important.
