Yes this question is cf related. I'm using cf 4.5 on win2k workstation.
I tested the printgif.java file in the java 2 print api documentation.
Worked fine from my workstation to a network printer. using this code I
wrote a cfx custom tag to do the same (print gif files from the cf server
to a network printer). when i run the cfx tag it executes correctly but
does not print ?? I setup a listener for the print job and it says that
the job completes correctly ??? What am I missing ??
My question -: if java code executes correctly why doesn't the same code
work rolled up in a cfx tag? I have played with security issues for the cf
service (logon) and the printer (access) with no luck.
The stipped down code I'm using is below. The cfx tag is called like this
<cfx_gifPrint file="c:\myfile.gif" debug="yes">
Any ideas greatly appreciated.
