Why is Java not enabled for the PDK? It's already running on all WebOS devices and making an interface for this would be so simple/easy. Any plans for this?

Hmm i thought unwiredben said WebOs don't have Java Support
but if it does it would make sense to include it.

Many of the services on the WebOS devices use Java to run.

Well then one would guess they would at least support it
if they use it.

Yes PDK should support Java, especially to run old-school Java ME (mobile) games.

Also would this also bring an advantage over Google and iPhone ?
I don't think they have Java support, i know that android is like
java but not compatible or something like that.

No, no, no. And furthermore: No. Jave ME is the devil.

I would say NO to Java ME as well... seriously why would you want to??

While webOS may be using Java in the current release to implement some internal services, this is an implementation detail and is subject to change in the future. Java isn't part of our strategy for application support.

You're thinking Java applets, which fell by the wayside around 2000. Java has found a place on the server side of some enterprise systems, but has been a pretty big failure in the mobile space and in the desktop browser. I appreciate some of the more elegant points of the language, but I'm happy to see Palm isn't pushing it for webOS apps.

Just read the Wiki about Java Applets and it seems javascript is a suitable alternative
for Java Applet well learned something new today :)

Java Applets are not dead, you should update your sources, it is true they have a bad start but nowadays they run quite well. I will let you take a look at two examples:

This one is a well known game:

http://www.minecraft.net/

This one is a game a guy made for a game competition:

http://www.digitalphoton.net/AAOA/AAOA.html

The two work like charm on Windows, Linux and Mac, and even a lot better in performance than flash games.

Now, there are also examples of games made in Java for the android platform which runs well too:

http://replicaisland.net/

In conclusion, Java itself is not a problem.

I work using Java for applets and webstart applications.

Super excited about node.js coming to webOS. For those who haven't been properly introduced, check this out:

Just a quick note for everyone who likes working with Java:

Oracle has released an embedded version of the Java SE, and it seems that Java 7 is also supported, not only Java 6

There are some requirements (Linux kernel version...etc) but I think WebOS 3.0 may be sufficient.

The most important thing is that it runs headful programs as well (Swing / AWT).

This is a huge step ahead of the Palm-included Java 5 (from the stone age)

Here is the link for download:
http://www.oracle.com/technetwork/java/ ... ml#sysreqs

When I receive my HP Touchpad in 2 weeks, I will definitely try to install this.

If the Oracle version runs properly on my HP Touchpad/WebOS 3, I will be quite happy, since I need my Java desktop applications to run on this.

Side note: The Oracle Embedded SE 7 will likely run on MeeGo based ARM devices as well.

For display, this version of Java requires X11. We don't supply that by default on webOS, but there is a version of the server that can be installed from Preware that's developed by the WebOS Internals team.

Josh Marinacci has been playing with some Java code, running on top of SDL on webOS:
