Migration from Swing to the web with Vaadin
ProCountor's migration started in 2013 from a Java Applet version of the application built in 2003. In the project it was decided early on to re-use as much as possible of the existing code-base and maintain interoperability between the Swing implementation (earlier AWT) by hiding the components themselves from the development team under an abstraction layer of generic UI components. The current Vaadin based solution then wrote implementations for the components that replaced the Swing implementations and by reusing 100% of the existing back-end.
"When Apple dropped support for their own JVM, we had to start supporting a Swing version of our app as well. The abstraction layer made it a natural choice for us to do the same with Vaadin, knowing that the API was so similar to both Swing and AWT. And that's what we did. Quite successfully I might add."
- Lauri Lehtonen, CTO
Procountor evaluated a few different frameworks and approaches before going with Vaadin. Their main criteria were that they wanted a full Java solution, for which reason the main competitor ZK lost. Vaadin also offered hands-on help with a proof of concept and later on on-demand help. Reusing a lot of the existing code also played a large role in going with Vaadin. The solution also leverages Vaadin Charts and Vaadin TestBench for testing the application. Taking into account the vastness of the application and developing an existing version in parallell, going from desktop to web in 2 years is a large accomplishment.
