I had to try TomEE

I had to try TomEE and I liked it (TomEE 1.5.2 plus).

I started of building a simpel model, then an ejb to end of with JAX-RS and JAX-WS.

I missed the @Stateless annotation on the dk/jarry/tomee/todo/ws/ToDoImpl.java class in the first run and it was a pain to find the error. Place to work on default values.

eclipse project in a zip file

I am thrilled to learn that TomEE have chosen CXF for both JAX-WS and JAX-RS.

Next on my ToDo list is using JPA to store data in Derby or MySQL.
