I've figured out the Java image part:
<cfset jpg = ImageNew(foo)>
<cfimage action="write" source="#jpg#" destination="test.jpg" overwrite="yes">
This works.
But the fact that the two jars seem to conflict with one another throws a real
spanner into the works... Is there any way I could separate them and have both
present in CF?

Stefan
