You can debug an application that needs an enterprise server to run even without configuring and associating a server beforehand.
If your project is not associated with any of the existing servers, when you start debugging, the IDE offers to create a temporary server configured for your project type and use that to run the application. The server is deleted when you close the project or the IDE.
To always use a temporary server without a prompt, go to Window > Preferences > Micro Focus > Enterprise Server, and click Always for Automatically create temporary server.
To debug using a temporary enterprise server:
If you have not configured the IDE to create a temporary server automatically, you receive a message that a temporary server will be created. Otherwise, the IDE creates the temporary server without prompting you to confirm.
This creates a temporary server which is configured for your project type of project and searches for the project output files in the output directory specified in the project's properties. This also automatically associates the server with your project and starts it.
Closing the project or the IDE deletes the temporary server.
