So many people came to JavaOne wrapup seminar held in Seoul, Korea on 8 July. It was organized as small scale(100 people expected) by Sun Korea, but I guess more than 200 people came in. I think it was so popular because this seminar covers most interesting topics in this year JavaOne - Java SE 6, Java EE 5, EJB3, Ajax and Scripting language.

My session was about "GlassFish, EJB 3.0 and Java Persistence API". Unfortunately time was short(40m) so I couldn't address the whole content in my presentation file. The presentation material covers more things than was metioned in the seminar. You can download it at the bottom.

Here is the abstract of my session.
