extends CardRuntimeException

TransactionException represents an exception in the transaction subsystem. The methods referred to in this class are in the JCSystem class.

The JCSystem class and the transaction facility throw JCRE owned instances of TransactionException.

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) 2.1 Specification for details.
