Hi
I have tried to implement the zoom-box facility of mapplet.
I have a virtual directory (IIS 5.0) set up to C:\MapServer\Project1 (on
Windows 2000)
I unzipped mapplet.zip to C:\MapServer\Project1\java\mapplet\
and followed all the steps of
1) inserted
<SCRIPT LANGUAGE="JavaScript">
function mapplet_apply(name, minx, miny, maxx, maxy, redraw) {
document.mapserv.imgbox.value = minx + " " + miny + " " + maxx + " " +
maxy;
document.mapserv.imgxy.value = minx + " " + miny;
}
function mapplet_error(message) {
alert(message);
}
</SCRIPT>
into the <HEAD></HEAD>
2) changing the form header to <form name="mapserv" method=GET
action="[program]">
3) putting in
<input type="hidden" name="imgxy" value="299.5 299.5">
<input type="hidden" name="imgbox" value="-1 -1 -1 -1">
4) swopping <INPUT NAME="img" TYPE="image" SRC="[img]" width="600"
height="600" border=1> for
<applet codebase="/java/mapplet" code="mapplet.class" width="600"
height="600" name="mapplet" MAYSCRIPT>
<param name="image" value="http://[host][img]">
</applet>
Unfortunately when I tried to open the page, the image was now just a grey
area covering 600x600 and no zoom box could be generated by dragging the
mouse.
I decided to wrap the applet code to
<object width="600" height="600"
classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i5
86.cab#Version=1,4,0,0"
standby="Please wait">
<applet codebase="/java/mapplet" code="mapplet.class" width="600"
height="600" name="mapplet" MAYSCRIPT>
<param name="image" value="http://[host][img]">
</applet>
</object>
in order to install JRE1.4 but once it downloaded, it corrupted the browser
(IE6) and asked me to debug the browser.
I then took out the <OBJECT> wrapper, (and the browser worked again) but now
it puts a red 'X' in the map image and says "Loading Java Applet failed...."
Is there anything that I am doing wrong.
Regards
Kevin
