yesterday night at the JBoss User Group Munich, I gave a speech about REST & JAX-RS & JBoss RESTEasy with my colleague Stefan Tilkov and I enjoyed the description of REST in 5 steps made by Stefan. After that Stefan ended with the REST fundament and the JAX-RS specification, I continued with the presentation of the full certified and portable JAX-RS implementation from the JBoss community (JBoss RESTEasy) and after all we ended the night with pizza meal and beer.
Here is the slides of the REST & JAX-RS & JBoss RESTEasy speech (Warning: this is a 7.6 MB PDF)
