Eclipse RAP is a framework to write Web application based on a Java API. This API is based on SWT, and allows to run existing SWT/RCP application as web applications from the same code base. With RAP 3.2 (Oxygen), there is a integration of e4 available and supported by the project team that allows to run Eclipse 4 applications in a web browser.
In this talk, we give a brief RAP introduction and show how to start developing RAP with a focus on Eclipse 4 applications. We will talk about the current state of the e4 integration, and show some best practices that we learned from our own projects. Finally we talk about the future direction and the latest contributions to the project.
