public class SystemException
extends CardRuntimeException

SystemException represents a JCSystem class related exception. It is also thrown by the javacard.framework.Applet.register() methods and by the AID class constructor.

These API classes throw JCRE owned instances of SystemException.

JCRE owned instances of exception classes are temporary JCRE 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 Java Card Runtime Environment (JCRE) Specification, section 6.2.1 for details.

Field Summary
static short ILLEGAL_AID
          This reason code is used by the javacard.framework.Applet.register() method to indicate that the input AID parameter is not a legal AID value.
static short ILLEGAL_TRANSIENT
          This reason code is used to indicate that the request to create a transient object is not allowed in the current applet context.
static short ILLEGAL_VALUE
          This reason code is used to indicate that one or more input parameters is out of allowed bounds.
static short NO_RESOURCE
          This reason code is used to indicate that there is insufficient resource in the Card for the request.
static short NO_TRANSIENT_SPACE
          This reason code is used by the makeTransient..() methods to indicate that no room is available in volatile memory for the requested object.
 
Constructor Summary
SystemException(short reason)
          Constructs a SystemException.

ILLEGAL_TRANSIENT

public static final short ILLEGAL_TRANSIENT
This reason code is used to indicate that the request to create a transient object is not allowed in the current applet context. See Java Card Runtime Environment (JCRE) Specification, section 6.2.1 for details.

ILLEGAL_AID

public static final short ILLEGAL_AID
This reason code is used by the javacard.framework.Applet.register() method to indicate that the input AID parameter is not a legal AID value.

Constant Field Values

NO_RESOURCE

public static final short NO_RESOURCE
This reason code is used to indicate that there is insufficient resource in the Card for the request.

For example, the Java Card Virtual Machine may throw this exception reason when there is insufficient heap space to create a new instance.

SystemException

public SystemException(short reason)
Constructs a SystemException. To conserve on resources use throwIt() to use the JCRE owned instance of this class.

throwIt

public static void throwIt(short reason)
