Here's a simple, useful example.
<cfscript>
function bhimginfo(imgfile){
jFileIn = createObject("java","java.io.File").init(imgfile);
ImageInfo = StructNew();
ImageObject =
createObject("java","javax.imageio.ImageIO").read(jFileIn);
imageFile = CreateObject("java", "java.io.File");
imageFile.init(imgfile);
sizeb = imageFile.length();
sizekb = numberformat(sizeb / 1024, "999999999.99");
sizemb = numberformat(sizekb / 1024, "99999999.99");
bhImageInfo = StructNew();
bhImageInfo.ImgWidth = ImageObject.getWidth();
bhImageInfo.ImgHeight = ImageObject.getHeight();
bhImageInfo.SizeB = sizeb;
bhImageInfo.SizeKB = sizekb;
bhImageInfo.SizeMB = sizemb;
}
</cfscript>
It will return image width, height, filesize (in bytes, kilobytes, and
megabytes)

Ben,
I've instantiated java before using cf but its not been all that simple.
What would be a good example of a simple but very useful java instantiation
suitable for a tutorial?
