Thank you for the course. I'll review the videos and course material to solidify my understanding. This was a lot of difficult material, but with your patience and presentation efforts I think we can all have some understanding of how to use these programming concepts/tools. Thanks for the great effort and patience with all our questions. You gave great answers to a host of varying questions. All of this will be useful to us as we continue to practice programming enterprise applications

I really liked the course, it was fast and gave me a quick overview of what is possible even when I was unable to do all homeworks during course which I will finish later. I think Sang is a greate teacher and this course has exceptional labs so you can really practice what you learnt!

Thanks a lot for all the services from jpassion.com. I am glad to be a member of jpassion. I feel that out of all the available online servies, this is the most economical and more interative and more java oriented.

I attended the Spring and Hibernate Code Camp and my experience and learning there has helped me get a very clear and concrete understanding of these frameworks. The camp's blend of lecture and coding sessions was a very effective methodology and the resources Sang put together for the hands-on coding sessions helped us get up-and-running from the first session itself. The practical exercises are very well laid out and the way he directed us on using the tools and technologies very clearly illustrated the core concepts and features of these technologies.

I've attended the 5-day Spring framework and Hibernate codecamp last week and I never thought it would be such fun. I enjoyed each day of the codecamp. Sang Shin is highly knowledgeable and takes pain in explaining difficult concept till we get it. I highly recommend the codecamp for anyone. I look forward to taking more codecamps from him.
