About the Applications

At Credit Europe Bank two tools are used, which are created with JavaFX.

The first one is an internal tool used by the developer team to define and setup certain procedures which are used within the applications and for their deployment. This tool is fully created in JavaFX, and was at the same time a research project to gain confidence in the power of Java and JavaFX to build a user interface application.

Based on the knowledge gained from the development of the developer tool, the decision was made to use JavaFX as the foundation to migrate an old application. This resulted in a new internal tool, used by the banking team and in the call centers. The screens of the old Swing application are integrated into this new tool, and are gradually transformed into React views. JavaFX components bind everything together and provide the main layout, menus, login screens, etc. The React views are integrated into this application with JxBrowser, a Chromium web browser that is fully integrated as a JavaFX component. For the call center team, the call manager was also integrated in this app, so they have all their tools available in one screen.
