Class SystemException

  • 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 Java Card runtime environment-owned instances of SystemException.

    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 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_USE
      This reason code is used to indicate that the requested function is not allowed.
      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.

      • ILLEGAL_VALUE

        public static final short ILLEGAL_VALUE
        This reason code is used to indicate that one or more input parameters is out of allowed bounds.

        Constant Field Values

      • NO_TRANSIENT_SPACE

        public static final 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.
        See Also:
        Constant Field Values

      • 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 Runtime Environment Specification, Java Card Platform, Classic Edition, section 6.2.1 for details.
        See Also:
        Constant Field Values

      • 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.
        See Also:
        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.

        Constant Field Values

      • ILLEGAL_USE

        public static final short ILLEGAL_USE
        This reason code is used to indicate that the requested function is not allowed. For example, JCSystem.requestObjectDeletion() method throws this exception if the object deletion mechanism is not implemented.

        Constant Field Values

      • SystemException

        public SystemException​(short reason)
        Constructs a SystemException. To conserve on resources use throwIt() to use the Java Card runtime environment-owned instance of this class.
        Parameters:
        reason - the reason for the exception

      • throwIt

        public static void throwIt​(short reason)
                    throws SystemException

        Parameters:
        reason - the reason for the exception
        Throws:
        SystemException - always
