I have been at JavaOne since 1996, its inaugural year. But this year I am on sabbatical in Vietnam, so I didn't get to enjoy the show.
However, through the miracle of the blogosphere, it is amazing how much information one can get without actually being present. In fact, maybe it's helpful to be outside the reality distortion field. Here is a summary from the Sage of Saigon.
I have been at JavaOne since 1996, its inaugural year. In 1996, JavaOne was
colocated with the Software Development conference, which has since fallen on
hard times and vanished. But at the time, half of the exhibitors were from SD,
and the other half from JavaOne. Weirdly enough, the JavaOne booths were all
yellow with a bit of red and blue, so it looked as if the SD half of the
exhibit hall represented the free world and the Java One half a totalitarian
regime. This year, JavaOne is again colocated with another conference, Oracle
OpenWorld, but I am on sabbatical in Vietnam, so I didn't get to enjoy the
However, through the miracle of the blogosphere, it is amazing how much
information one can get without actually being present. In fact, maybe it's

hinted, Java SE 7 will have
and be delivered in 2011. Java SE 8 is promised for 2012.
2. I didn't hear anything about Java EE 7, but that's ok—the EE 6 app
servers are just rolling out.
3. There were encouraging words about commitment to GlassFish and
3. The big surprise announcement is Java FX 2.0. A release is promised in
2011 with an ambitious roadmap . There
will be Java bindings to the API, which means you no longer have to use FX
Script. Now that's something that I have asked for ever since I first heard of
Java FX. (By the way, FX Script will not be developed further.) Also promised
are a rewrite of the media stack, a new accelerated graphics stack called Prism
that works outside the AWT, and a mechanism for rendering a scenegraph to HTML
5. All of this has been touted as “Swing 2.0”.
I am baffled by this, in particular, the timeline. We were told that it
would take until
mid-2012 to deliver the originally planned Java SE 7. Fair enough, but how
can Java FX 2.0, which seems at least as ambitious, come out so much more
quickly? Someone still has to work out some pretty basic details, such as how
is going to be done in a Java API. Multimedia has not been a strong point of
Java FX in the past; see for example
blog to get a feel for some of the issues. Prism sounds great, but it's not
something for which I could find any public information. And I don't begin to
understand the HTML 5 angle. Every time that I hear “rendering for
multiple display technologies", I run for the hills. Remember Java FX Mobile?
(By the way, that's now dead too.)
I very much want to see a modern client-side library for Java, and if
Fowler says that Swing isn't going to cut it, I'll look forward to Java FX
2.0. Provided, of course, it is available under GPL and, at least as of SE 8, a
part of the platform. But I am not getting the warm and fuzzy feeling that this
is going to happen without pain, or by 2011.
4. I was equally baffled by the
announcements. The quote that stuck in my mind was from Thomas Kurian:
“I would not underestimate our capability [of] delivering a new Java
platform [in this space]”.
Ok, count me among the under-estimators.
Yes, I get the point that there are 10x more feature phones than smart
phones. I have one of them. But I am not running a single Java app on it. I
wouldn't even know how to get one. (I tried once and was hit with some
outrageous data charge—thanks, Verizon.)
A while ago, I used a Blackberry. It had a bunch of fine apps, but those
weren't Java ME. Ok, not true. There was one Java ME app that I ran—a
terminal emulator. Very mainstream...
Right now, I use an Android. It has a bunch of great apps, but they aren't
Java ME either. In fact, I understand that Oracle has issues with that
I realize that elsewhere in the world, people do use Java ME apps, but it
really seems like fighting yesterday's battle. And if I did want to fight
yesterday's battle, I would promise to give feature phones the good 90% of what
smartphone users enjoy—apps that integrate with the calendar, messaging,
maps, and media on their phone (and, for that matter, Java-based calendar,
messaging, mapping, and media for those phones that don't have them—like
that feature phone that I no longer use since I got the Android.) I don't see
keep mobile Java alive. (And no, I didn't understand where WebKit comes into
So, here is what I conclude, from my vantage point as the Sage of Saigon:
- Java SE 7 and 8 will be delivered pretty much as planned
- GlassFish and NetBeans will stay viable choices for developers, at least
in the near term
- Something called Java FX 2.0 will materialize, but it will be late, not
have all promised features, and not be Swing 2.0. Eventually some viable
Swing replacement will emerge from the good parts. In the meantime, Swing
will be left to wither on the vine, and it will be a challenging time for
Java desktop developers until the dust settles.
- Java ME will continue to lag behind developer expectations
If I am wrong, I will really need to attend Java One 2011 to get a better
reading of what is happening.
