Tutorials

The schedule may change/shift due to illness or conference attendance.

The easiest way to go through most of the examples unless stated otherwise is to use JDK 8. Newer JDKs are missing some WS related libraries, which need to be supplied extra, and there are common version issues. Examples tested in Eclipse IDE 2023-12 for Enterprise Java and Web Developers. Bring your own laptop with required SW installed, if possible, and connect using ethernet - eduroam credentials should work.
