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.

Since:

1.4

Constructor Detail

GSSException

public GSSException(int majorCode)

Creates a GSSException object with a specified major code.

Parameters:

majorCode - the The GSS error code for the problem causing this exception to be thrown.

---

GSSException

public GSSException(int majorCode,
                    int minorCode,
                    String minorString)

Creates a GSSException object with the specified major code, minor code, and minor code textual explanation. This constructor is to be used when the exception is originating from the underlying mechanism level. It allows the setting of both the GSS code and the mechanism code.

Parameters:

majorCode - the GSS error code for the problem causing this exception to be thrown.

minorCode - the mechanism level error code for the problem causing this exception to be thrown.

minorString - the textual explanation of the mechanism error code.

Method Detail

int the GSS-API level major error code causing this exception

See Also:

getMajorString(), getMinor(), getMinorString()

---

getMinor

public int getMinor()

Returns the mechanism level error code for the problem causing this exception to be thrown. The minor code is set by the underlying mechanism.

getMinorString(), setMinor(int, java.lang.String)

---

getMajorString

public String getMajorString()

Returns a string explaining the GSS-API level major error code in this exception.

Returns:

String explanation string for the major error code
