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.

Direct instances of this exception class are not bound to any context and can be passed between contexts without any restrictions. Objects created and returned by the methods of this class are owned by the caller. In particular, a call to the Throwable.toString() returns a String instance bound to the owner context of the caller.

See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.

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 caller 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.
 
Constructor Summary
SystemException(short reason)
          Constructs a SystemException.
 
Method Summary

Field Detail

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 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 caller context. See Runtime Environment Specification, Java Card Platform, Connected Edition, chapter 6 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.

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.

Constant Field Values
Constructor Detail

SystemException

public SystemException(short reason)
Constructs a SystemException.

Parameters:
reason - the reason for the exception
Method Detail

throwIt

public static void throwIt(short reason)
                    throws SystemException
Deprecated. Deprecated for extended applets and web applications on the Connected Edition of the Java Card 3 Platform. Use constructor instead.

Throws a new instance of SystemException with the specified reason.

Note that a new instance is thrown upon each call to this method.

This method is for backward compatibility with Java Card 2.x and for interoperability of classic applet applications with the Java Card 3 Classic edition.

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