Tim,
I had a whole bunch of bother with this on RH7.2.
In the end I switched the JRE to Sun j2re 1.4.1_02 as you did and with the
help of a java blokie I know eventually created this.
<cfscript>
imageObject = CreateObject("java", "javax.imageio.ImageIO");
fileObject = CreateObject("java", "java.io.File");
fileObject.init(newfile);
thisImage = imageObject.read( fileobject );
width = thisImage.getWidth();
height = thisImage.getHeight();
</cfscript>
I suspect that I could cut out the java.io.File bit, by using a JavaCast to
pass the file name directly into imageObject as a string, but the above
works, so why fix something thats not broken.
Hope that helps
Regards
Stephen
