Java Day Tokyo Trip Report

Guest Author

Java Day Tokyo 2014 was held on May 22nd. Organized by Oracle Japan, it is the largest Java developer event in the country. Indeed it is really a replacement to JavaOne Japan. This was another highly successful year for the event with a fully sold out venue packed with youthful, energetic developers. Speakers included Steve Chin, Stuart Marks, Simon Ritter, Nandini Ramani, Cameron Purdy and Yoshio Terada. Topics included Java SE, Java EE and JavaFX.

Cameron Purdy, Vice President of Development at Oracle responsible for Java EE, shared the Java EE 8 road-map during the opening keynote. You can download video of the keynote here.

Following the keynote, I reviewed Java EE 7 and went into more details on Java EE 8 possibilities during my session titled "JavaEE.Next(): Java EE 7, 8, and Beyond". The sizable room was completely packed for the session. At the beginning of the session, I asked the audience whether they wanted to hear more about Java EE 7 or more about Java EE 8. To my pleasant surprise, the audience indicated that they knew about Java EE 7 and wanted to know more about Java EE 8. I talked about possibilities such as HTTP 2/Servlet 4, Server-Sent Events (SSE), a new standard action-oriented web framework, security simplification, multitenancy, REST management/monitoring, CDI 2, platform-wide CDI alignment, more pruning, JCache, configuration, JMS.next() and Java SE 8 alignment. The slides for the talk are here:

I also presented my talk aligning Java EE 7 with the HTML 5/JavaScript Rich Client landscape. I use AngularJS for my demo but the concepts can apply to any JavaScript (or even native mobile) front-end. This session was a full house with standing room only. The slide deck for the talk is posted below:

The demo code is posted on GitHub: https://github.com/m-reza-rahman/javaee-javascript. Do give me a shout if you need help getting the demo up and running but it should be very straightforward.

Besides my sessions, there were a good number of other Java EE related sessions including from Japanese Java EE evangelist Yoshio Terada (naturally he delivered his talks in Japanese). One of the most interesting of these was a talk titled "Move from J2EE to Java EE" by Hirofumi Iwasaki of Rakuten. For those who don't know what Rakuten is, it is one of the largest e-commerce platforms in the world (by volume) based in Japan. Hirofumi-san made the case for transitioning to Java EE from J2EE and avoiding non-standard frameworks. He blogged about his talk here. His slide deck is embedded below:

He is doing a similar talk at JavaOne 2014 titled "Java EE 6 Adoption in One of the World’s Largest Online Financial Systems".

At the end of the day, we had an "Ask the Experts" panel. I was on the panel along with Steve, Stuart, Simon and David. There was some lively discussion around Java EE, GlassFish and WebLogic that the audience seemed to really appreciate. I too enjoyed the panel.

Fortunately, the trip to Japan wasn't all work and no fun. I was largely expecting to just check out the vibrant Tokyo nightlife, but it turned out I had more free time than I was expecting. As a result, I got to do a whirlwind tour of sights like the Imperial Palace, Senso-ji/Asakusa, Meiji Shrine, Tokyo Skytree, Kabuki-za (I got to check out Kabuki - the legendary Japanese traditional opera), Shinjuku, the insane Tokyo Metro, the dazzling Shibuya Crossing, Tokyo Central Railway Station and a few others. Perhaps next time I'll aim for more of the nightlife such as the Robot Restaurant, Sumo wresting and Japanese heavy metal (yes, there is such a thing). All in all, Japan was a mystifying mix of centuries old traditions and ultramodern fixtures. Just check out the pictures I took below, you'll see what I mean:

I also got to do something I was really looking forward to - check out the Mount Fuji area (some of those pictures are in the album too). Unfortunately, the official climbing season is July though August, denying me the opportunity to ascend one of the most iconic mountains on the planet. Technically I could have attempted it renting the proper gear but it would have probably been a little foolhardy considering I would have been alone and I am not in the kind of shape I once used to be in. Oh well - I guess it's good to have some things to do later in life, perhaps with my wife Nicole once we are at a stage where we can seriously think about doing this sort of thing again (and hopefully can still afford it :-)).

I definitely enjoyed Java Day Tokyo and hope to be part of the event next year again!
