IIRC, Java will search class paths in order and uses the first match it finds. So, I'm thinking since CF starts up, loads the built-in POI jars, then eventually sees your app and loads the Jars again, albeit newer versions, then this new version is lower in the 'order' The disclaimer here is that I'm not a JAR head by trade :) I think you could add the Jar in the CFAdmin tool, restart CF, then check the JVM details and see if your JAR is higher in the order, it should be. Might need to add this JAR in the jam.config manually though. (I left that typo in, SpaceBalls! ) ok, jvm.config. EIther of these might affect the CF tags using POI though.
A classic post on adding Jars is below, though I'd start with http://carehart.org/cf411/ first :) http://blogs.adobe.com/cantrell/archives/2004/07/the_definitive.html HTH Douglas Knudsen douglasknud...@gmail.com On Sep 20, 2012, at 7:11 PM, Mike Staver <sta...@fimble.com> wrote: > I can't find any good documentation from Adobe yet on how to dynamically load > and then use jar files.
