Java question

[Cay Horstmann]

I am trying to find out how to run Java GUI applications on the OLPC. I
installed Java by downloading and executing

jre-6u3-linux-i586-rpm.bin

It works--if I ssh -X into the machine from a Linux box, I can
successfully run Java Web Start applications such as

/usr/java/jre1.6.0_03/bin/javaws http://www.horstmann.com/violet/violet.jnlp

But when I try the same from the terminal activity, I just get a screen
filled with "Java Application Window" (which would normally appear as
the title decoration of the main window).

Similarly, when I place a JAR file onto the OLPC (such as
ResourceTest.jar from Core Java vol. 1 ch. 10), it runs beautifully when
I ssh -X into the machine, but when I execute it on the machine itself,
I get a blank screen.

I suppose this has something to do with the window manager on the OLPC.
Is there any way to overcome this?

Thanks,

Cay
