# Class GSSException

org.ietf.jgss.GSSException

All Implemented Interfaces:
  `Serializable`

public class GSSException extends Exception
This exception is thrown whenever a GSS-API error occurs, including any mechanism specific error. It may contain both the major and the minor GSS-API status codes. Major error codes are those defined at the GSS-API level in this class. Minor error codes are mechanism specific error codes that can provide additional information. The underlying mechanism implementation is responsible for setting appropriate minor status codes when throwing this exception. Aside from delivering the numeric error codes to the caller, this class performs the mapping from their numeric values to textual representations.
