JCertif 2011 University - Java EE 6 Hands-on Lab

Brazzaville is the largest and capital city of the Republic of the Congo and is the host of JCertif - the biggest Java community event in central Africa. Its a really long flight from San Francisco (about 22 hrs flight time) and takes you in the Southern Hemisphere. But the excitement in developers was every bit worth traveling. Also met this awesome guy in the flight working for World Health Organization who are consolidating their 100 disparate systems using Oracle CRM.

However I got the very first feel of Africa when I was stopped at the Congo-Brazzaville immigration for the yellow fever certificate. In spite of me clarifying multiple times that the visa is already stamped on my passport and I submitted my yellow fever vaccination certificate to the Congo consulate in the US, the immigration officer just kept repeating "phortee dhollar". The immigration office is no place to fight for your principles especially when you don't know the local language. So I cringed, paid $40, got a receipt, got a fake yellow fever certificate, and finally got out. The immigration officer was almost ready to inject the yellow fever vaccination to me which fortunately I avoided. But just as a travel tip, make sure to carry your vaccination card whenever you enter Central Africa in general. It does not matter whether you have the visa pre-stamped or not. Another fellow passenger was charged $10 because his vaccination fever was valid from a later date. Taking a taxi from the airport to the hotel was another challenge because of the local language. But the airport staff was very helpful and I finally reached the hotel safely.

Anyway, the first evening was spent in meet-and-greet the JCertif team. There were JUG leaders from Nigeria, Kinshasa, Togo, and other organizers. The expected attendees on that day were 70 and the actual were about 150 which posed a logistical challenge but they handled it gracefully.

Earlier today, about 50+ attendees got a 4-hr crash course in Building Web Applications using Java EE 6, NetBeans, and GlassFish. The workshop built a complete end-to-end application using Java Persistence API, Enterprise Java Beans, Contexts and Dependency Injection, Servlets, Java Server Faces, and other technologies. NetBeans wizard-drive approach and rapid deployment on GlassFish makes the entire process quite a breeze. Most of the attendees could complete the lab and then started helping other attendees as well.

The slides used in the workshop can be downloaded from here and the source code built during the lab can be downloaded here.
