Java Web Start Critiqued: Is It Now 'Production Quality'?
In a recent article on JavaLobby,
scalemania asks When Will Java Web Start be Production Quality? The article starts out with a folksy portrayal of what Java Web Start (JWS) offers:
Java Web Start (JWS) has always had great potential. With this deployment platform I can reach users such as mom-and-pops who would otherwise have to call their son (me) when they need to download and install something from the internet. Mom-and-pops are not that interested in computers but they know how to write an email and click a link on a webpage. To start a JWS application all they have to do is click a link on a webpage. While the application is being launched it is also cached locally. It can be started offline and updates are detected and installed automatically.
That's all good. As is the fact that Java Web Start peruses the user's system, installing Java SE if needed, and detecting whether extra permissions are needed (in which case, the user is presented with a security dialog).
What's wrong with JWS, in
scalemania's view, is poor documentation and the bugginess of central features, along with "strange" implementations of some features.
scalemania's revisit to Java Web Start was the recent release of JDK 6 Update 18, which James Sugrue covered in a recent JavaLobby post. Among the highlights of this release is support for Windows 7.
scalemania notes that important problems in the updated Java Web Start are listed as being fixed. This includes issue 6888118 - JNLP Extension Installer is never invoked when uninstalling appliction, an issue
scalemania reported himself:
Uninstalling a JWS application on windows is supposedly simple. The user navigates to the same place in the windows Control Panel where native applications are uninstalled, finds the JWS application and hits "uninstall". Unfortunately JWS has been broken and would only uninstall some parts of the application – in some cases leaving the user with a system that would complain again and again that the remaining pieces of the application was crashing.
So, when will Java Web Start be "production quality"? Actually, the bugs addressed in JavaSE 6 update 18 appear to represent a significant portion of the most critical bugs on
I'm happy that many critical bugs have been addressed but some of them are regression bugs. So with these fixed, what has been broken now? Alright thats a bit pessimistic, I really want to use JWS and I hope update 18 will turn out to have production quality! :)

Jim Weaver reports on JavaFX Layout Secrets with Amy Fowler (video):
Amy Fowler is the Sun engineer tasked with creating JavaFX layout functionality. As noted in the slide below from her presentation at the Silicon Valley JUG, Amy cites a few applications and notes that they each have profoundly different user interfaces. Upcoming versions of JavaFX must have the ability to express UIs that, for example, have a traditional Swing appearance and behavior, as well as highly graphical and fluid 2D and 3D UIs that users are coming to expect...
