It's a RedHat 9 / Cold Fusion MX 6.1 server with Java 1.4.2., so:
http://java.sun.com/j2se/1.4.2/docs/api/javax/imageio/package-tree.html

It appears as though the code I'm testing attempts to use imageio:

calling template code:
objImageInfo=createObject("component","tmt_java_img");
stImageInfo=objImageInfo.getDimensions("MJK.gif");
writeoutput(stImageInfo.width&" x "&stImageInfo.height);

relevant line in 'tmt_java_img' component:
jBufferedImg=createObject("java","javax.imageio.ImageIO").read(jFile)

Being a newbie, I'm not sure what the best way is to install the
necessary package (I'm familiar with rpm and apt). Any pointers would
be appreciated.

Thanks for the help!
