Just a quick question.

I'm much more familiar with the Java environment, so still learning the CF way.

Is there a way to get the classid value of the Java object that gets created by 
coldfusion? This will help me to dump the TransDAO classid when displaying the 
transid value. If the classid is the same, then it will prove the singleton 
implementation.

Tks
Andre
