That was exactly the solution I was looking for. All works as it should now. Kudos on a good tutorial and thanks again for the help!

If you call each one of those methods using separate <cfinvoke> calls then it won't work because you are using three different instances of the same CFC. Personally, I would do it all in <cfscript> like as follows. <cfscript> imageUtils = CreateObject("component", "yourCFChere"); imageUtils.load("filepath"); imageUtils.thumbnail(250); imageUtils.writeResult("resultpath"); </cfscript> Matt Liotta President & CEO Montara Software, Inc. http://www.montarasoftware.com/ V: 415-577-8070 F: 415-341-8906 P: [EMAIL PROTECTED] > -----Original Message----- > From: Chris Kief [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, July 24, 2002 6:13 PM > To: CF-Talk > Subject: RE: Image manipulation with CFMX and JAI > > One final question...do you have any code examples for invoking the cfc? > Since load, writeResult and thumbnail are distinct methods, it appeared > that you had to cfinvoke each one individually.
