java.lang.LinkageError: loader constraint violation

612367Dec 6 2007 — edited Dec 7 2007

I am using ToplinkEssentials as a persistence provider in a J2SE desktop application. I've encountered the following error.

java.lang.LinkageError: loader constraint violation: loader (instance of sun/misc/Launcher$AppClassLoader) previously initiated loading for a different type with name "expendituretracking/Employee"

I have unsuccessfully searched for a clue as to what is causing this problem. Any help is appreciated.
