If you package your application as described in Packaging ULC-based applications in XD, your application will be enabled for production mode. The following procedure enables you to run your application as a server from a development image:
MyUlcApp class>>registerInUlcSystem UlcSystem registerApplicationNamed: 'MySample' withStartupClass: MyUlcView
Your image is now ready to accept new connections from multiple UI Engine components.
UIEngine\bin\ulcUI.exe -url ulc://localhost:4444/MySample
If connecting to the application from another machine, replace localhost with the IP address of the machine running the application. As appropriate, replace 4444 with the server port assigned earlier.
If your application does not run for any reason, ensure that the Debug option is enabled on the ULC->Debug menu. Retry the previous sequence and watch the System Transcript window for error messages.
