What, if anything, talked about on Day 1 of JavaOne 2008 was of any import to Java developers?
Another year, another JavaOne.
It's always great to see so many old friends again.
This year seems to be continuing the attendance growth trend of the last couple of year so that's a good sign. Also, I've been able to find enough actually interesting and useful talks to keep from going back to sleep and that's an even better sign. In particular, this is starting to show how the "Java community" is growing up and outwards to encompass more than just the same old things.
Here's my list of the key things from Day 1:
What a joke. JavaFX was announced with great fanfare at last year's JavaOne and yet what has actually been released in a year? Nothing of value. Just more hoopla and blah blah blah. Way too little, way too late. Especially now that Adobe has started opening up Flash and friends.
JAX-RS: RESTful services in Java
Yes, REST is here to stay. JAX-RS is the attempt to standardize how to build RESTful services in Java. Basically, the approach is to use a number of new bits of library (such as the URI builder that makes working with URIs actually not a completely bug-inducing nightmare) and a bunch of new annotations.
There are already at least a few implementations out in the wild including the "Jersey" reference implementation and one for the Restlet framework.
The JAX-RS (aka JSR-311) draft specification has just been released for public review -- check it out and send in your comments.
Is there anybody left out there in Java-land that hasn't yet gotten the memo that concurrency is a big issue today and is becoming a huge issue moving forward?
Brian Goetz's talk, Let's Resync: What's New for Concurrency on the Java Platform, Standard Edition, was primarly about one key way to solve a number of problems was very well attended and people should check it out online.
Basically, coming in Java v7 is an addition to the java.util.concurrent library which adds a lot of support for building Fork-Join style concurrency solutions. For those who can't wait, check out Doug Lea's existing implementation that is part of his util.concurrent library.
Java v7 looks to have some nice features that both allow for very general Fork-Join solutions as well as things like the ParallelArray class which makes it ridiculously easy to concurrently process arrays of information. Joe Bob says: Check it out.
