How to determine current search path?

[Rick Mann]

For debugging purposes, is there a way to determine what class directories
and jar files will be searched, and in what order, for a given context? I'm
happy to insert code into a servlet or JSP to dump this information, but I
want to be sure of the actual search path, considering all environment
variable settings, class loader settings, etc.

Is this possible? Is there a Java class that contains this information to
which I can make this query?

TIA,
