|Sahoo and I delivered OSGi-enabled Java EE Applications using GlassFish and Eclipse Hands-on Lab at Eclipse Con 2011 earlier this week. The conference had an excellent line up of sessions, speakers, receptions and I wanted to engage but could attend only one day. The keynote on the third day titled "The Java Renaissance" was jointly delivered by Mark Reinhold, Chief Architect of the Java Platform group at Oracle and John Duimovich, Java CTO at IBM. Read more coverage of the keynote and Oracle's participation here.|
The hands-on built a simple User Registration and Authorization application and showed different combinations of OSGi and Java EE development and deployment in GlassFish. The first step was to to deploy a simple OSGi service and client in GlassFish. Then the OSGi client was replaced by a Web Application Bundle (aka hybrid application) which used @OSGiService for dynamic discovery, bind, inject, and track the OSGi service (more details in TOTD #154). Then the service bundle was replaced by a JavaEE application using EJB and JPA. There were detailed instructions (PDF) to go through all the exercises. The screencast #38 (video) walks you through building the entire application, the video inlined here too:
About 35 attendees were able to make progress after the spotty Internet connection started working. The 5 USB sticks provided by Eclipse Con turned out pretty handy to pre-load all the software requisites. We shared a zip of our ".m2" directories and "m2eclipse-\*" plugins directory for the folks with no Internet. The high point for me was when one of the attendees finished the entire lab in a little over an hour and left. That also helped us assess the quality of document which we tried to make pretty self explanatory. We found one missing instruction from the document and have already fixed it. Overall, about 60% of the attendees completed the lab and rest of them left with partial setup and instructions. Let us know if you attended the lab and found it useful.
Many thanks to Doug and Ankush, the Student Assistants assigned by EclipseCon for our labs, to help attendees keep chugging along!
I was also "lucky" to win a BlackBerry 9670 smartphone + remote stereo bluetooth gateway + international charger + headset. The RIM folks told me that this worth $700 but Amzon sells the raw phone for $19.99. The total cost comes out way under $100 even after including all the accessories. Anyway this device runs only on Sprint so of no use to me. Are you interested in purchasing ? :-)
The reception in the evening (typically the best part) was great and gave me a chance to socialize with several folks. Here are some pictures captured from the event:
