We have a few applications that output images using the cfcontent tag with
no dramas, but are developing a function that uses ZXing to create a
barcode that we’re having trouble outputting and returns the error message
“missing format”. The code snippet is:
<cfset format=createObject(‘java’,‘com.google.zxing.BarcodeFormat’)>
<cfset
writer=createObject(‘java’,‘com.google.zxing.oned.Code128Writer’).init()>
<cfset
matrix=createObject(‘java’,‘com.google.zxing.client.j2se.MatrixToImageWriter’)>
<cfset barcode=writer.encode(“1234”,format.CODE_128,75,75)>
Full stack trace is:

Any ideas what the “missing format” might mean and what we might do to get
this script to spit out an image?
Thanks… Simon
