An example of a Template Method that handles "rollback on exception" in Java

ExecuteSomething.java

new RollbackOnExceptionAction(new JtaTransactionService())
    .executeInTransaction(new Closure() {
        @Override
        public void execute(Object... arguments) {
            // cast arguments
            // perform action
            // throw exception if there's a problem
        }
    });

RollbackOnExceptionAction.java

public class RollbackOnExceptionAction implements ExecuteInTransaction {
    private final TransactionService transactionService;

    public RollbackOnExceptionAction(TransactionService transactionService) {
        this.transactionService = transactionService;
    }

    @Override
    public void executeInTransaction(Closure closure) {
        try {
            transactionService.beginTransaction();
            closure.invoke();
            transactionService.commit();
        }
        catch (Exception signalRollback) {
            transactionService.rollback();
        }
    }
}
