I have uploaded my web services lecture slides. They are available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.5 license.

The lecture has been planned for 20 hours, with 10 hours of actual lecture and 10 hours of assignments. It starts with a few XML notions. Then, the general concepts of SOA are presented, before heading to the SOAP web services technologies, including BPEL. Finally, REST-style web services are introduced before the last lecture which is about AJAX applications and web services mashups.

You may find errors and weaknesses in the lectures, so please do not hesitate to contact me to discuss about it :-)
