Class APDUException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

javacard.framework.CardRuntimeException

javacard.framework.APDUException

public class APDUException
extends CardRuntimeException

APDUException represents an APDU related exception.

The APDU class throws Java Card runtime environment-owned instances of APDUException.

Java Card runtime environment-owned instances of exception classes are temporary Java Card runtime environment Entry Point Objects and can be accessed from any applet context. References to these temporary objects cannot be stored in class variables or instance variables or array components. See Runtime Environment Specification, Java Card Platform, Classic Edition, section 6.2.1 for details.

Field Summary

Fields

Modifier and Type	Field	Description
static final short	BAD_LENGTH	This reason code is used by the APDU.setOutgoingLength() method to indicate APDUException.BAD_LENGTH if len is negative, or greater than 256 and the currently selected applet does not implement the javacardx.apdu.ExtendedLength interface, or if non BLOCK CHAINED data transfer is requested and len is greater than (IFSD-2), where IFSD is the Outgoing Block Size.
static final short	BUFFER_BOUNDS	This reason code is used by the APDU.sendBytes() method to indicate that the sum of buffer offset parameter and the byte length parameter exceeds the APDU buffer size.
static final short	ILLEGAL_USE	This APDUException reason code indicates that the method should not be invoked based on the current state of the APDU.
static final short	IO_ERROR	This reason code indicates that an unrecoverable error occurred in the I/O transmission layer.
static final short	NO_T0_GETRESPONSE	This reason code indicates that during T=0 protocol, the CAD did not return a GET RESPONSE command in response to a <61xx> response status to send additional data.
static final short	NO_T0_REISSUE	This reason code indicates that during T=0 protocol, the CAD did not reissue the same APDU command with the corrected length in response to a <6Cxx> response status to request command reissue with the specified length.
static final short	T1_IFD_ABORT	This reason code indicates that during T=1 protocol, the CAD returned an ABORT S-Block command and aborted the data transfer.

Field Details

ILLEGAL_USE

public static final short ILLEGAL_USE

This APDUException reason code indicates that the method should not be invoked based on the current state of the APDU.

• Constant Field Values

BUFFER_BOUNDS

public static final short BUFFER_BOUNDS

This reason code is used by the APDU.sendBytes() method to indicate that the sum of buffer offset parameter and the byte length parameter exceeds the APDU buffer size.

See Also:

• Constant Field Values

BAD_LENGTH

public static final short BAD_LENGTH

This reason code is used by the APDU.setOutgoingLength() method to indicate

• APDUException.BAD_LENGTH if len is negative, or greater than 256 and the currently selected applet does not implement the javacardx.apdu.ExtendedLength interface, or if non BLOCK CHAINED data transfer is requested and len is greater than (IFSD-2), where IFSD is the Outgoing Block Size. The -2 accounts for the status bytes in T=1.

See Also:

• Constant Field Values

IO_ERROR

public static final short IO_ERROR

This reason code indicates that an unrecoverable error occurred in the I/O transmission layer.

See Also:

• Constant Field Values

NO_T0_GETRESPONSE

public static final short NO_T0_GETRESPONSE

This reason code indicates that during T=0 protocol, the CAD did not return a GET RESPONSE command in response to a <61xx> response status to send additional data. The outgoing transfer has been aborted. No more data or status can be sent to the CAD in this Applet.process() method.

See Also:

• Constant Field Values

T1_IFD_ABORT

public static final short T1_IFD_ABORT

This reason code indicates that during T=1 protocol, the CAD returned an ABORT S-Block command and aborted the data transfer. The incoming or outgoing transfer has been aborted. No more data can be received from the CAD. No more data or status can be sent to the CAD in this Applet.process() method.

See Also:

• Constant Field Values

NO_T0_REISSUE

public static final short NO_T0_REISSUE

This reason code indicates that during T=0 protocol, the CAD did not reissue the same APDU command with the corrected length in response to a <6Cxx> response status to request command reissue with the specified length. The outgoing transfer has been aborted. No more data or status can be sent to the CAD in this Applet.process() method.

throwIt

public static void throwIt(short reason)

Throws the Java Card runtime environment-owned instance of APDUException with the specified reason.
