 Constructs a new servlet exception when the servlet 
 needs to throw an exception and include a message
 about the "root cause" exception that interfered with its
 normal operation.  The exception's message is based on the localized
 message of the underlying exception.

 This method calls the getLocalizedMessage method
 on the Throwable exception to get a localized exception
 message. When subclassing ServletException, 
 this method can be overridden to create an exception message 
 designed for a specific locale.

 
 Parameters:rootCause  the Throwable exception
     that interfered with the servlet's
    normal operation, making the servlet exception
    necessary
