A different extension folder

Is there a way to define or add a different extension directory (other then <JRE>\lib\ext) in a way that the extension class loader will automatically load the JARs in that directory?
(I am trying to avoid writing a custom class loader)

Thanks!

-extdirs <directories>

thats for compiling, am not aware of an option for the vm.

YOu should be able to use URLClassLoader instead of writing your own loader.
Would just need to pass it a list of all jar files in the directory.

I know about the URLClassLoader, but I am trying to find a simpler way...
For now, I found a very nice (and working) property that is called java.ext.dirs. I can control the extention directory by passing it to the execution line with a -D option.
But this is not good for what I need. I want it to be modfied at runtime (just like using my own the URLClassLoader).
Now I am trying to change this property at runtime, but I guess that this wont work since the class loading architecture does not probe the extention folders (for my knowledge...) during runtime.
