Most blogs have my improvements under the main example, just look inside the
comments section.
It should not error out I tested the code here before I post it.
What Denny was talking about is we found 4 different ways to compile java
source into usable classes which then can be used as objects by coldfusion.
The main tranfer method used so far is a classloader (any Bootstrap will do)
which loads a dynamic
class into a object at runtime.
But not this Bootstrap
<cfdump var="#createObject("java", "com.sun.jdi.Bootstrap
").virtualMachineManager()#">
I have no idea what addVirtualMachine will do inside the context of
coldfusion.
sun.tools has a lot crazy stuff.
