Class SystemException

java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.RuntimeException
javacard.framework.CardRuntimeException
javacard.framework.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.

    • 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.

    • 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:

    • 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:

    • 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:

    • 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.

      See Also:

    • 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.
