JBOX - Java problem - move button

[Pierre RELLA]

I use Jbox (windowsNT) for zoom.
When i draw a rectangle in the map i have the Applet JAVA error like:
"netscape.javascriptJSException: Failure to evalue
setbox_handler("jBox,311.0,72.0,403.0,116.0);
 at sun.plugin.javascript.ocx.JSObject.eva(Unknown Source)
 at evalThread.run(Unknown Source)
box=true, drag=false"
When i submit the execution on the HTML page i have the Zoom done. What
don't work in Java?

I want to have a button to move in the map and i don't know how make?

Best regards
