     }

    
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

Returns the exception that caused this servlet exception.
