Putting the final touches on NetBeans 6

A lot of people I know have already switched to the NetBeans 6 betas, getting early access to the array of new features in this version, even though it's not, you know, done yet. On a number of occasions over the last few months, I've been following a discussion on a forum or IRC chat, and the solution has been "oh, that's way better with NetBeans 6, just switch to that." And I don't recall too many cases where users have been burned by bugs in the milestones and betas, even though these releases are buggy and incomplete by their very nature.

So for everyone who's already switched to NetBeans 6, the announcement of Release Candidate 1 is surely a must-have. Those who've kept up with the betas have probably already downloaded it, and are anxiously awaiting the final release in the coming weeks.

And if you're not using NetBeans, take a look at version 6's "what's new" list and see if there's something there that wouldn't make your life a little easier. I'd been IDE-free for years before giving NetBeans a fresh look while developing a Glossitope widget earlier this year, and even though I expected not to like the visual GUI builder, I was surprised by how practical it is for building highly-customized, attractive GUIs. Given that NetBeans 6 adds Beans Binding, Swing Application Framework, and integrated profiler support... oh yeah, I've already downloaded RC1. Even if you're not a GUI developer (and odds are you're not), there's much here to like.

It will be particularly interesting to see if NetBeans can make inroads into the Ruby community by filling the need for a comprehensive Ruby IDE. But that's speculation for another blog...


Also in Java Today,
an interactive graphic on SDN's Mobile Service Architecture (MSA Overview) page offers an interactive graphic showing the JSRs that go into making up JSR-248, the Mobile Service Architecture umbrella specification. Clicking on any of the JSRs takes you to the SDN page with resources for that JSR. The block diagram shows how the various layers of the spec relate to one another, and how the JSRs are organized by function: security and commerce, graphics, communication, personal information, and application connectivity.

Steve Roy has posted version 1.1 of his MRJ Adapter for accessing Mac-specific Java functionality. "MRJ Adapter is partially a wrapper around some APIs provided by Apple and which are built into their various virtual machines. However, they have changed over time and some APIs were not always available, so MRJ Adapter provides a consistent API for the developer wanting to target the Mac. MRJ Adapter is an easier path for developers because it is easier to learn, leveraging concepts they already know, such as action listeners to handle menu items. It also shields the developer from the problems associated with compiling their code on other platforms when the APIs they need only exist on the Mac." MRJ Adapter is open-source and published under the Artistic License.


In today's Weblogs Bruno  Souza has a JUG-touring travelogue that combines Bagels, Airports and User Groups.
"What bagels, airport and missed planes have to do User Groups? For the past several weeks, I have been in such a crazy schedule of travels, visiting so may cities and User Groups, that they are all intermixed."

Harold Carr checks in with an encouraging set of
Metro Web Services / .NET 3.5 Plugfest Results.
"3 Sun development engineers were at Microsoft's Redmond campus last week to test interoperability between future releases of Metro Web Services and Windows Communication Foundation in .NET 3.5. Here are our latest results."

David Walend wonders
How big is that boolean[]?
"I won't bore you with the details, but we are computing a lot of solutions to a problem in advance, and looking up the answer in a big multidimensional boolean array. For this particular puzzle, the size and accuracy of the problem we can solve depends on how big a monster boolean array we can pack into memory."


In today's Forums,
fsa3 poses an
ERM Question.
"I'm sort of new to ERM, and want to verify I'm on the right page. I have 2 classes I'm trying to setup the mapping for, Program and ProgramDetails for which a Program can have a list of details. I'm having trouble deciding how to define the primary key for program details object. From a pure DB perspective I would have a 2 part key (ProgramID and a Seq No). I'm not sure how to lay that out using JPA and then have to show that only 1 part of the key has the relationship/FK."

goeh is working through a race condition in
EJBTimerService and rescheduling on server startup.
"I have a problem with the EJB Timer Service in v2-b58g. When the server has been down for a while and expiration time for single-action timers has passed, it tries to reschedule them when the server starts again. But the problem is that the rescheduling happens to early in the startup process. My @Timeout method uses JPA to persist objects, but from what I can see JPA has not yet been initialized. This results in exception."

Almost as if to beg an RTFM, lobrien9 asks about
Drag and Drop? "Can someone tell me if it is possible to implement dragging and dragging of objects in a java app? I'm sure it is but I was hoping someone could let me know if it's in Swing or AWT?"
