FISL is the biggest open source
conference in Latin America and had about 7000 participants in the FISL 12 that concluded
earlier this week. This was my third consecutive year (2010
and 2009)
and as every year the conference was packed with lectures, workshops,
demonstrations, booths, presentations, and lot more. |
Anil Gaur, VP of Java EE Platform and GlassFish, gave a presentation on
"Oracle GlassFish Server: A flexibly, light-weight, and
production-ready Java EE 6". There were about 100 attendees in the
theatre-style seating. The talk gave a great overview of the
explosive growth happening in the GlassFish community on all fronts. It
also gave an overview of how GlassFish is the first platform to provide
clustering and high-availability for Java EE 6 applications with
full commercial support
from Oracle. The 2-instance session failover demo that I started to
show in the talk did not work completely and my digging is still going
on but here is a basic analysis so far.
- The GlassFish High Availability depends on GMS which further relies on UDP
Multicast (more details
here). I've shown this demo on my previous machine (a Macbook)
multiple times and in different configurations of with or without an IP
address. But multicast is enabled by default on Macs. However Natty
Narwhal does not seem to be configured that way, at least by default.
And so even though I could create a cluster, the application with HA
enabled could not be deployed.
- The GlassFish
3.1 Certification Matrix
provides a complete list of supported platform and Ubutnu 10.10, not
11.04 (demo machine), is listed as a supported developer platform.
There might be bugs in this newest release of Ubuntu or how Grizzly
picks a network interface for binding when there is no bind interface
address setup and the default interface (eth0) is not connected.
More details on how this will eventually get fixed in a later blog.
Other than that I gave two presentations on "The Java EE 7 Platform:
Developing for the Cloud" and "Running your Java EE 6 Applications in
the Cloud: and the slides are now available:
There were about 60+ attendees for the 9am talk on Java EE 7. Check out
more details about the evolution of Java EE 7 at
javaee-spec.java.net.
All the component JSRs have their independent pages as well with the
format: <component>-spec.java.net where <component> is
"jpa", "ejb", "servlet" and "jsf".
The second preso turned out a lot more fun than originally planned with
the two surprise co-speakers - "Javali" and "Code Monkey". The audience
seem to enjoy the interesting conversation as part of the talk,
pictures below. There is usual engaging with the community, talking to
folks at the booth, explaining
Oracle's
open source strategy, and customer visits.

Spotlight podcast #36 where Anil Gaur talks about GlassFish 3.1.
There were several other talks given by Oracle employees covering JDK
7, NetBeans, OpenJDK, MySQL and other
open source offerings.
