How to manage the Rhapsody process from within a JavaFX application

Question & Answer

Question

How do I properly terminate the IBM Rational Rhapsody process from within a JavaFX application?

Cause

You have observed that the Rhapsody process does not terminate when:

Closing the JavaFX application via its window close button
Using the Rhapsody API method IRPApplication.quit()

Answer

You should call both IRPApplication.quit() and RhapsodyAppServer.CloseSession() methods to properly terminate the Rhapsody process and the RhapsodyAppServer session.

You can also use the JavaFX EventHandler interface so that the above methods are called when the "X" close button is clicked in the window user interface.




package application;



import com.telelogic.rhapsody.core.IRPApplication;

import com.telelogic.rhapsody.core.RhapsodyAppServer;



import javafx.application.Application;

import javafx.event.EventHandler;

import javafx.scene.Scene;

import javafx.scene.layout.BorderPane;

import javafx.stage.Stage;

import javafx.stage.WindowEvent;





public class Main extends Application {



	IRPApplication app = null;



	@Override

	public void start(Stage primaryStage) {

		try {

			// create Rhapsody session and IRPApplication object

			app = RhapsodyAppServer.createRhapsodyApplication();



			BorderPane root = new BorderPane();

			Scene scene = new Scene(root,400,400);

			scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());

			primaryStage.setScene(scene);

			if (app != null) {

				primaryStage.setTitle("Connected to Rhapsody (" + app.getBuildNo() + ")");

			}

			primaryStage.show();

			

			// Window OnClose event

			primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {

				public void handle(WindowEvent we) {

					// close the Rhapsody application object

					app.quit();

					// terminate the Rhapsody session

					RhapsodyAppServer.CloseSession();



		        }

			});

		}

		catch(Exception e) {

			e.printStackTrace();

		}

	}



	public static void main(String[] args) {

		// launch the JavaFX Application object

		launch(args);

	}

}
