/**
 * This is the root interface of the exception hierarchy defined
 * for the Connector architecture.
 * 
 * The ResourceException provides the following information:
 * <UL>
 *   <LI> A resource adapter vendor specific string describing the error.
 *        This string is a standard Java exception message and is available
 *        through getMessage() method.
 *   <LI> resource adapter vendor specific error code.
 *   <LI> reference to another exception. Often a resource exception
 *        will be result of a lower level problem. If appropriate, this
 *        lower level exception can be linked to the ResourceException.
 *        Note, this has been deprecated in favor of J2SE release 1.4 exception
 *        chaining facility.
