Coldfusion - getting image dimensions


I'm running ColdFusion MX 6.1 on a RH server, and I would like to find a way to get an image's dimensions. I found the following example after trying google:

Code:
<cfobject type="JAVA" action="Create" name="tk" class="java.awt.Toolkit">
<cfobject type="JAVA" action="Create" name="img" class="java.awt.Image">
<cfscript>
    img = tk.getDefaultToolkit().getImage("/usr/local/apache2/htdocs/cheater.jpg");
    width = img.getWidth();
    height = img.getHeight();
</cfscript>
<cfoutput>#width#<br>#height#</cfoutput>
There was an error with that code, as some of the replies on that page mention. The suggested solution was to remove the parenthesis from tk.getDefaultToolkit(). I did so, and got the following error:

Element GETDEFAULTTOOLKIT is undefined in TK

Does anyone know what's causing this, or perhaps a better way to get at the images height and width?

An update: I tried using a cfdump to see the contents of the toolkit variable tk. This cfdump actually generated a "Java bean access" error. Googling that proved fruitless.

Did some more googling, and found the following custom tag for ColdFusion. Works excellently.
