Follow Sun's guidelines from the SDK documentation:

See if this little app. gives you any ideas.

Note that early VM's (both MS 1.1.4 and Symantec 1.1.5)
render this text backwards, but since it is Swing based,
that problem is avoided.)

I just tried it using IE 6.0026 and..
Java(TM) Plug-in: version 1.5.0
Using JRE version 1.5.0-beta Java HotSpot(TM) Client VM

It seems to work fine here.

Are you using beta or the RC release?

I'm using 1.5.0, not the preliminary versions. Do I need an additional
download for the Swing part?

(scratches head) No, it is all standard Java API Swing classes.
The code is directly below the launcher.

You can get the unformatted source here.
<http://www.physci.org/codes/display.jsp?fmt=raw&fl=/codes/eg/JArabicInUnicode.java>

It should work in Java 1.2+. theoretically, ..checks in
the on-line compiler, no, the call to JFrame.EXIT_ON_CLOSE
on line 69 makes it 1.3+.

I would like to here from other beta and RC users of 1.5.

A couple of things missing from your report steve..

a) did you visit the page, or are you just repeating
what Mickey reported?

b) If you visited and got that exception, what exact Java/OS
are you running? (See the properties applet..
