Course Outline
This Java Web Services course provides a thorough guide to the design and implementation of RESTful web services using Java. We take students from the fundamental concepts of the REST architectural style and its embodiment in existing web standards, all the way through the creation and testing of a REST service. The course also illustrates how the decades-old HTTP protocol can in fact elegantly address a variety of "enterprise scale" issues, including high concurrency and atomic transactions.

Here are some reviews of the training vendor.
This course was very, very interesting due to the instructor. He was simple, gave good examples and made a few jokes. Also, being only 5 participants was a bonus for us as we were able to share our experiences in a timely manner.

I think there is too much material to cover in one session. It's a lot of information to absorb all at once.

The only thing I would add...if you know you don't have many participants, hands on practice would be great. I would like to have had more time applying what i learned in a diagram. Once I got back to my office...i didn't know how to move a shape and associated text together. I also would like to know where I can see all the shapes offered by visio instead of searching for the shape and not knowing what to call it?

The instructor was excellent. I was pleasantly surprised by how interesting she made a potentially dry subject appear. Non-stop, great snacks provided all day from ham/egg bagels for breakfast, muffins, Valentines chocolate, chips, popcorn, gumball machine, coffee, juices etc etc. Perfect location for me as it was 2 blocks from my office.

I had no problem with the instructor's technigues, methods or delivery of the course material. He made what was otherwise fairly dry material as interesting as he possible and augmented it with practical examples that the class could relate to. The training facility and staff were also comendable, however what can't be overlooked is the IT infrastructure. During the exam the problems with latency were so bad that it affected my ability to concentrate on the material. Prior to the exam I completed 2 practice exams on paper in 35 & 37 minutes respectively. Doing the exam online it took over 1.5 hrs because it would take between 30 & 60 sec to refresh the page and show the next question. At times when I attempted to go back and review quesgtions I had marked I found my original answer wasn't recorded & I'd have to answer the question a second time. By the end of 70 min I was so digruntled I couldn't wait to finish regardless of the end result. It may not seem fair to evaluate the favility in this manner, but as a student the outcome is the ultimate measurement of a training favility.
