RAP for Java Developers

The Rich Ajax Platform (RAP) is an Eclipse Java technology for building rich browser-based applications. It enables developers to reuse their existing Java and Eclipse know-how and provides means for sharing code between web- and desktop-applications. This course teaches you everything you need to use RAP for developing web applications.

Using course material designed by the RAP project leaders and committers, the people who literally developed the technology, this course accelerates your adoption of this powerful platform. Our veteran Eclipse developers, with years of product development experience, teach you everything you need to develop RAP-based web applications. Along the way they are able to provide insights, best practices and context to help you to start your own development efforts and keep on track.

Course participants incrementally develop a full RAP application from scratch in a series of hands-on focused sessions. Keeping a small class format (max. 6-8 participants) ensures that you'll gain a broad understanding of Eclipse RAP and get plenty of individual support from our experts.

Duration: 4 days
