Important Installation Note:
The Java ME SDK 3.0 for Mac OS requires Java 1.6. You can download Java 1.6 from Apple’s update website or install it via the Mac OS “Software Update”. Next, be sure to verify Java 1.6 is set as the default runtime for Java applications in the Java Preferences (Applications->Utilities->Java Preferences).
For more info and a screen shot check out the Java ME SDK blog.

I’m running Mac OS X 10.4 and SoyLatte (http://landonf.bikemonkey.org/static/soylatte/) as Java SDK 1.6 has not been ported to Mac OS X 10.4 yet.
When I try to run Java ME SDK 3.0 for Mac OS I get the following error:
java.lang.UnsupportedClassVersionError: Bad version number in .class file
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:620)
at org.netbeans.JarClassLoader.doLoadClass(JarClassLoader.java:240)
…
it pretty much goes like this for another page or so.
Also, if I open a project I get ‘unresolved reference problem’, and the following suggestion:
Problem: The project uses the Java Platform called “CLDC Sun Java(TM) Micro Edition SDK 3.0 EA”, but this platform was not found.
Solution: Click Resolve and create new platform called “CLDC Sun Java(TM) Micro Edition SDK 3.0 EA”.
However, clicking on the resolve button doesn’t help as I don’t know how to set the platform to be anything else than 1.5 which I’m given by default and which is the latest Sun Java SDK that I have installed (note: SoyLatte java 1.6 is the preferred one in my Path).
Did anyone try running Java ME SDK 3.0 on Mac OS X 10.4? Did you encounter similar problems, and have you managed to solve them?
Thanks a lot,
Veljko

Veljko,
I saw the same errors initially when using Java 1.5. Only after upgrading to Apple’s Java 1.6 *AND* setting the Java Preferences to tell the system to use the 1.6 version did the Java ME SDK work.
I haven’t used SoyLatte yet – so I am guessing here – but first I’d make sure that SoyLatte is actually used as the runtime when starting the Java ME SDK. Have you set the JAVA_HOME and JAVA_SDK env variables? And where does /System/Library/Frameworks/JavaVMframework/Versions point to?
Cheers,

Hi,
Thanks for the reply. Unfortunately, I didn’t manage to get it running…
The soylatte is in /usr/local/soylatte16-i386-1.0.3 and I set my JAVA_HOME and JAVA_SDK to point to the same directory.
I created /System/Library/Frameworks/JavaVMframework/Versions/1.6.0/Home that points to /usr/local/soylatte16-i386-1.0.3 and /System/Library/Frameworks/JavaVMframework/Versions/Current and CurrentJDK point to that 1.6.0 directory.
When I call “java” from the command line I get the right version (1.6) but Java Preferences doesn’t allow me to set anything but 1.5 as the default, so that’s no way to go obviously. Is anyone aware of another way to make sure that Java ME SDK is indeed using JVM 1.6?
Cheers

Great! But I am surprised to see this coming earlier than the Linux version! Do we have an estimated release date for that?

The Linux version of the Java ME SDK 3.0 is coming. In the meantime you can use the WTK 2.5.2 version for Linux: http://java.sun.com/products/sjwtoolkit/download.html

Thanks Terrence, it’s what I am using already. Unfortunately it (and the Windows version as well) has a severe bug when receiving datagrams (http://forums.sun.com/thread.jspa?messageID=3050861�), which blocks the app for 5 seconds (in my case) per datagram. Multiple datagrams in a row = long block = unusable.
I still don’t understand why the Mac version should have precedence, but well, I’ll wait.
Thanks again and keep up the good work.

If you download Early Access from http://java.sun.com/javame now it works on jdk 1.5 and jdk 1.6 as well. Above mentioned problem has been fixed.

Thanks for this note/notice. Running nicely in Netbeans on my Mac.
One simple question – should the JavaFx Mobile device within this build work? I have my J2ME applications working, just cannot seem to get the Fx Mobile Compiles to run on the Mac Version.
Any suggestions?
Thanks in Advance

Are you trying the DefaultFXPhone1 or the DefaultFXTouchPhone1? What are the problems you are seeing?
01/28/2010 at 13:32
Simo
Hi currydt, how did you manage to get the J2ME 3.0 to show in NetBeans? I’m using NetBeans 6.8, there is no selection to add this SDK.

Unfortunately, the Java ME SDK 3.0 for Mac currently does not integrate with NetBeans on the Mac.

Can it be that J2ME SDK for Mac OS has been removed? I can only find the Windows version on the site linked.

Sorry for the slow reply. The link to the Mac version is still there, it’s just hidden a bit in the text. The link is: http://www.oracle.com/technetwork/java/javame/downloads/sdk30-mac-jsp-137878.html
