Do ABAP developers have to learn Java?
No. Since with SAP Web Application Server there is no technology or feature that would be undoable with ABAP, there is no immediate need to learn Java. With BSP, there is also a sufficient technology for Web based development. In fact we think that in the foreseeable future any kind of applications can also be done with ABAP. However, in the future SAP may come up with more Java based technologies and applications, which may not be available on the ABAP side. These then would need the knowledge of the Java language and technologies.
