jBox Java applet

Hi Rich,
Thanks for correcting me the way I have specified the archive. I have
changed the code base to "c:/Inetpub/wwwroot/MapServer/java/jBox"
And archive to "jBoxPNG.jar.
But after hitting the "initialize" button, when I looked at the
generated source code , I found that the path to the png map image
generated by Mapserver was incorrect. Previously,I had put the code for
displaying the map image as:
<param name="image" value="http://[host][img]">
But my image was in heep://localhost/MapServer/Docs/tmp folder.
So I changed that line to:
<param name="image" value="http://[host]/MapServer/Docs/[img]"
But the problem is, when mapserver put the value for [img], it creates
it as: " \tmp\ITASCA11011353302004.png"
Therefore I'm getting the value for the map image in the source as:
<param name="image"
value="http://localhost/MapServer/Docs/\tmp\ITASCA11011353302004.png">
But I'm not getting the way so that the mapserver could correctly get
the path to the image.
An after doing all these changes, I neither see the map in the browser
not the java consol error. So, I'm not sure whether the java applet is
being called and executed or not.
If someone could point to the mistake I'm doing, please help me with
this..
Thank you,

Looks like there are problems with your codebase and archive
parameters. You have:
codebase="java\jBox"
archive="jBoxPNG.jar,png.jar"
The way you have codebase, the 'java' directory will not be found. I
assume that 'mapserver' is an IIS virtual directory, so try:
'codebase=/mapserver/java/jbox'
Forward slashes, not back slashes, as this is a URI, not a DOS path.
I'm a little unclear on the specification of two jar files in the
archive parameter. Is that legal? Where'd you come up with that? And
you have the .jar files in /mapserver/java/jbox/ not a subdirectory,
right?
You might want to start with GIFs and the standard jBox, rather than
jBoxPNG which requries the sixlegs library. If you're using the Sun
Java VM, you don't need six-legs anyway.
I am cc'ing the mapserver-users list as others may spot something that I
missed.
