Constructor:
 public ServletException() 
 public ServletException(String message) 
    Constructs a new servlet exception with the specified message. The message can be written to the server log and/or displayed for the user.
    Parameters:
    message - a String specifying the text of the exception message
 public ServletException(Throwable rootCause) 
    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.

    Parameters:
    rootCause - the Throwable exception that interfered with the servlet's normal operation, making the servlet exception necessary
 public ServletException(String message,
    Throwable rootCause) 
    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, including a description message.
    Parameters:
    message - a String containing the text of the exception message
    rootCause - the Throwable exception that interfered with the servlet's normal operation, making this servlet exception necessary
