Roland, Thank you! The only problem is that i don't always have access to the classes directory on shared hosting. Would it work to place ImageInfo.class in a mapped directory? In the custom tag path? Somewhere else? Is there a way to set Java class paths via the Service Factory, like you can set DSNs? Newbie questions, but that's where i am today!

Drop the ImageInfo.class file in your \CFusionMX\wwwroot\WEB-INF\classes directory, then drop the ImageInfo.cfc wherever you want. You can get the information as follows: <CFSCRIPT> ii = createObject("component", "ImageInfo"); stProperties = ii.getImageInfo("c:\tese.gif"); </CFSCRIPT> <CFDUMP VAR="#stProperties#"> Hope this helps!

I'd have to sit with it for a few days to distill the essential functions from this class, see how they work, and try and implement them via CF. But it seems it should work. I've also found the same technique used in PHP and VB examples, read the first few bytes and extract the height and width information from the header. In any case, i think it would be very useful to refine this for CF, as it's probably the most commonly needed use of Java in CF. :) nando -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of PC Carraway Sent: Wednesday, September 01, 2004 4:30 PM To: [EMAIL PROTECTED] Subject: Re: [CFCDev] Using a Java class in CF to get image width and heig ht Nando I'm still on the lookout for an SWF solution. Good luck if you find one before me.
