Oracle Technology Network: Java Workshop

It’s time for another workshop from Oracle. As usual, I receive a workshop invitation from Oracle:

Modern Enterprise Java Development

Dear Ashrufzz,

You are invited to attend the Oracle Technology Network (OTN) Java Workshop, a free, hands-on workshop that will focus on Java EE 6 and designed to enrich the development experience of enterprise Java developers.

  • Gain a better understanding of Oracle WebLogic Server’s capabilities and a glimpse into Java EE 7 and cloud enablement
  • Dive into the different layers of a typical Java EE Web application and learn how to implement them using the latest Java EE features
  • Learn how the latest Java EE 6 features provide a modern, lightweight Java development experience
  • Gain insight into why scaling web applications is challenging and learn some tips and tricks on how to deal with the issues involved
  • Hear about the integration of Coherence and Oracle WebLogic Server and Oracle GlassFish Server and the native capabilities of each servers for HTTP session state management
  • Learn how to configure and use powerful Eclipse plug-ins to develop, build, and deploy with Maven and Hudson for continuous build integration
  • Learn how to develop a simple Java console-based application to access, update and remove simple types of information from a Coherence-clustered cache

I arrived at Oracle’s HQ in Level 23, The Garden. I guess they are cutting down on cost so the only goodies I get is an Oracle folder, a few sheets of paper and an Oracle Linux CD. It’s okay with me since it’s kind of annoying to bring along my laptop back-pack along with a bunch of goodies especially when you take the train to come to MidValley.

The first session was presented by Cipto Wibowo Herlianto, OFM Solution Consultant-ASEAN. He is based in Singapore and I believe he is an Indonesian by the way his name is spelled. There was supposed to be another speaker but he came in late therefore Cipto had to cover for him.

Cipto’s topic was “Developer Experience with WebLogic Server and the Cloud” where he explained about Oracle WebLogic product regarding its features and many more things.

For me, the Oracle WebLogic is a fantastic tool to administer an enterprise application for a big scale environment. Of course the learning curve would be a bit steep especially for those who had never handled any big enterprise application before. For those who do, the features can be really helpful.

Cipto also showed the audience a hands-on view of how to deploy 2 applications where one is the new version and side by side replacing the old version with a new one without compromising the uptime of the application. A feature where high availability application demands most.

My knowledge in Java is quite limited so I couldn’t really understand what Java EE6 can do or could not do.

The second speaker is Chuk-Munn Lee where he talked about “Exploring Java EE 6”.

I really admire Mr. Chuk-Mun Lee because of his vast knowledge on Java. He was also unafraid to tell the audience the truth about Oracle and Sun (He claim he was from Sun) in terms of the product strength and weaknesses. Among some notes I’ve managed to collect:

  • GlassFish Server V3 – Is free and most probably the most advanced web server application in the market
  • JRuby – Is faster than the original Ruby
  • WebXML – Format everybody loves to hate
  • The use of annotation “” – If you have source code
  • The use of XML – If you don’t have source code/file
  • Multitenancy in Java EE 7
  • Scaling application in thread – requires a lot of CPU
  • Some overview of JRockit and how it can be used to manage application

I’ve never heard of GlassFish before eventhough one of the application my company is selling is using Tomcat and Jetty and based on Spring Framework. I think it’s time for my company to focus on Java instead of PHP. It was also the first time I’ve head of Maven and Hudson so it was an eye opener for me too.






Some of the materials being presentated was way beyond my IT knowledge so I had to pick up my pace on it using Wikipedia while during the talk. Again, I was fascinated by the dashboard showed by Mr Chuk together with his hands-on demonstration. How I wish I had the skills that he has. It was then time for lunch:

I could still remember the lunch I had during my last visit. It was fabolous. This time around, we were only served with packed lunch. Oh well, that’ll do.

The afternoon session was the “hands-on” approach. My laptop was running at peak performance causing my CPU fan to work extra hard. I was left with only 13GB of hard disk space (Total capacity-160GB) on my aging laptop. How I wish my company could provide me with an upgrade to my nearly 3 year old laptop eversince my own laptop died on me because of overheating I supposed.

Check out my laptop which barely meet the minimum laptop requirement:

General requirements Software requirements My Laptop

There were 2 hands-on lab:

  1. Oracle WebLogic Server Development with Eclipse, maven and Hudson
  2. A Step-By-Step Guide to Oracle Coherence

I only managed to finish the 1st lab. By the time I was finished, it’s already time to leave.

Looking forward to another event (please invite me again ok?).

Thank you Oracle.
