We're Gonna Take On The World
Can the Java Plug-In compete?
It's a strange day for Desktop Java developers when AjaxWorld is publishing an article about using Swing for your client-side technology, while the Java sites are asking whether the Java Plug-In is even viable.
Having walked away from the ever-brittle Ajax market to develop his own Java-based RIA product, Marvin reports that many developers reject it out-of-hand because it depends on the Java plug-in:
This has been a major disappointment to say the least. I knew that applets had developed a stigma over the years, but I didn't realize how pronounced the distaste for the plug-in had become. The negativity and skepticism within the Java community itself is so overwhelming that any hope for wide acceptance of the plug-in seems impossible. The funny thing is that all the developers I have talked with would like the plug-in to become widely accepted, but in order for it to become widely accepted, it would have to be used, however, most website developers are hesitant to use it, because, well, it's not widely accepted.
So how does the plug-in gain traction? In a follow-up post, he says that a scatter-shot appeal to hobbyists and other amateurs won't make the Java Plug-In viable:
So how about you? What would convince you that you could deploy a business application that depended on the Java Plug-In?
Ironically, we're calling attention to this discussion on the same day that our Java Today section also has an article from AjaxWorld (of all places!) about Developing Rich Client Applications Using Swing, in which Mauro Carniel makes the case for Swing (in an applet or as a Web Start-deployed application) as the front end to a multi-tier enterprise application. He lays out the needed data binding and data retrieval tiers needed to connect an enterprise backend to a Swing GUI, and discusses many Swing-based sets of graphic components, including JGoodies, JIDE, OpenSwing, and more. A promised follow-up article will look at IDE support for Swing client-side development.
Also in Java Today... Elliotte Rusty Harold thought he new the well-worn
java.lang.Math class really well. "Imagine my surprise, then, when I recently happened to be reading its Javadoc for possibly the first time in half a decade and realized that the class had almost doubled in size with 20 new methods I'd never heard of. Obviously it was time to take another look. Java 5 added 10 new methods to java.lang.Math and Java 6 added another 10." In Java's New Math, Part 1: Real Numbers, Elliotte focuses on "the more purely mathematical functions provided, such as
The SDN interviews Joshua Bloch about the second edition of Effective Java in More Effective Java With Google's Joshua Bloch. In it, he talks about the folly of premature optimization, writing your own libraries instead of using what's already out there, strange things in Java and undesirable side-effects of signed bytes and of autoboxing, Java's complexity budget, the future of Java, and more.
Back in the Forums,
haihovu has a practical question about applets in JApplet instantiation outside of EDT. "Hi all, I have recently been stuck with a problem with one of my application which is an applet. The problem was encountered when I attempted to use the Substance look and feel (https://substance.dev.java.net/), whose author is very adamant about adhering to Swing's rule of creating components inside EDT (event dispatching thread) only, and will throw exceptions if this rule is violated."
Finally, BD-J developer
elbob is challenged by
Changing Titles and Catch MainMenu call. "I'm using several titles for my BD-J app to show something like "Menu" on the player display when I'n in the Main Menu and show time info when playing clips. Also I can then easily use the Play button in my menu title which is interactive. It seems to be very important to stop a running player before switching to a playlist with autostart! If it is not stopped WinDVD crashes. (haven't tested on other players) I can control everything nicely by receiving ServiceContextEvents. When I get a PresentationTerminatedEvent I just stop my player. The problem starts when I try to access my Menu or a Title via Title search or Disc Menu Button. This makes the player crash again because I don't get the terminated event. Is there a way to receive the DiscMenu call so I can react to it?"
In today's Weblogs, Carla Mott covers
GlassFish V3 logging changes. "Logging in GlassFish V3 has undergone some changes to leverage the logging utility in JDK. This blogs reviews where we are with those changes in Prelude and how to use what is there."
Masoud Kalali keeps it concise with a
One pager review of GlassFish version 3 features. "If you are looking for a simple one page overview of GlassFish version 3 this entry is for you."
Finally, Terrence Barr offers an ME perspective on new client-side SE technologies in Java SE 6 update 10 released. "Admittedly, at first sight this has little to do with mobile and embedded Java - but bear with me.Java SE 6 update 10 is big news because it essentially recalibrates the Java runtime and desktop Java."
