public class SystemException extends CardRuntimeException
SystemException
represents aJCSystem
class related exception. It is also thrown by thejavacard.framework.Applet.register()
methods and by theAID
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 thejavacard.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 themakeTransient..()
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.- See Also:
- Constant Field Values
-
NO_TRANSIENT_SPACE
public static final short NO_TRANSIENT_SPACE
This reason code is used by themakeTransient..()
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 thejavacard.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.- See Also:
- 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.- See Also:
