Sun Is Porting Java To the iPhone
krquet notes an InfoWorld article on Sun's plans for the iPhone. After studying Apple's newly released SDK docs for 24 hours, Sun decided it was feasible to develop a JVM, based on Java Micro Edition, for both the iPhone and the iTouch. An analyst is quoted: "I think going forward, with the SDK, it takes out of Apple's control which applications are 'right' for the iPhone." The article doesn't speculate on how Apple might to react to such a loss of control. "Apple had not shown interest in enabling Java to run on the iPhone, but Sun plans to step in and do the job itself... The free JVM would be made available via Apple's App Store marketplace for third-party applications."
Sure, possibly security or performance. More likely, NIH.
For one thing, if iPhone developers choose to just use Java, then the applications could run on other phones relatively easily.
For Swing apps, isn't that Apple's fault? They did the JVM port to OSX, after all... they had the power to make the JVM merge the Swing menu with the Apple menu using OS hooks.
Instead, they chose to have it display at the top of each application like Windows and most XWindows GUIs.

Java ME is already part of the default platform for DVB/ATSC (European / N American cableTV clients), most mobile phones, and Blu-Ray (so all HD videodiscs). When it's on the iPhone, JME will get high visibility as a development platform (DVB/ATSC/BD-J and even most mobile phone development is nearly all done by a small niche of developers).
The same JME applets will run on any of those devices. In fact, the Java classloader lets any running Java program load a class from any other Java device connected by the network, load it and run it (safely) locally.
I wonder whether having lots of developers targeting a very featureful terminal that can be used as a "universal remote" for all these personal devices will finally offer some good applications for Java's ability to transmit the same objects around all the devices. Like the GUI objects installed in each device being available on any other device, to control the "home" device in familiar terms. Or any other of these.
And if that "mobile objects" platform does indeed come of age, will even Sun's "JavaSpaces" finally have a use for its far-out platform?
Will all of Sun's "useless" Java platforms from the past decade+ eventually be recognized as "visionary"?

Well, they're not all that bad. It's mostly smaller projects, like PCGen that are the worst offenders, and some more widely used ones like Azureus never really got good Mac interfaces. For example, when you make the Azuerus window smaller, instead of adding a scrollbar it just covers stuff up bit by bit. So you can make it small, but if you want all of the statistics to be available you have to leave it at a fairly large size. Azureus's interface is the main reason that everyone I know has switched to Transmission.
And I don't want to sound all negative, because there are plenty of good Java based programs on Mac. For example, Lux does a great job with the interface (maybe because it started on Mac and was ported the other way), but I'm still worried. The prospect of hundreds of developers jumping on the iPhone thinking "I already know Java, so I don't have to learn anything new" seems like it could end badly. I guess we'll have to wait and see what happens, if Sun does go through with this.
Agreed that Java is preferred to Flash.

Java is a decent language. The library support is fantastic. With Sun opening up Java, its time to reconsider the use of a VM to draw our desktops. Certainly Java is preferred to Mono
Still, there is a certain amount of Java-biased derision echoing about slashdot. Perhaps those issues need to be addressed before advocating the embracing of Java. Yet it is a decent language, one of the best of the curly bracket languages
May I recommend doxygen for your documenting needs. Does what javadoc can do + more (can create 'call graphs', works on several languages, and outputs to html, pdf, manpages, rtf etc etc). It is truly an impressive piece of software.
Lack of planning on your part does not constitute an emergency on mine.
Apple has every right to lock in the iPhone, yes, but that doesn't mean we have to go along with them.
.NET, Silverlight, Moonlight, it's all the same vigorous viral ecosystem.
As for Silverlight... no thanks. Microsoft has proven that their 'no sandbox' security model is completely unworkable so many times that it amazes me that anyone would consider taking yet another spin on the wheel. ActiveX,
sorry but you are wrong.
if you have a java application and want the menu bar to appear at the top of the desktop (like all other OS X apps), then simply invoke the jvm/java app and pass the following system property as a JVM arg:
-Dcom.apple.macos.useScreenMenuBar=true
as described here
its not that complicated....
