Class TransactionException


  • public class TransactionException
    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 Java Card runtime environment-owned instances of TransactionException.

    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.
