[Mapserver-users] Problem with Mapplet

[AMC Story]

Hi,

I'm new to MapServer, but have managed to get the demo up and running and am 
currently trying to get the mapplet working too.  I've followed the 
instructions in the HOWTO, and it would appear that the applet is accessed.  
However, while the rest of the interface looks fine, I get a grey box instead 
of my map.  Also, I'm now getting a MSIE warning box that simply 
says "mapplet  ", and when I move the mouse around the screen you can see a 
message in the status bar of the browser that says "exception: 
java.lang.NullPointerException".  

I thought originally that the file paths could be wrong (I'm running the 
demo_init and the java files from my public_html directory on my local machine 
and the other files from my scripts directory, which has worked until now, but 
might be a problem...?).  

If anyone has any idea what I might be doing wrong I'd really appreciate it.

Thanks
Ali Story
