 * $Log: AbstractLedgerTest.java,v $
 * Revision 1.1  2004/03/22 23:20:51  pelle
 * Working on Hibernate Implementation.
 *
 * Revision 1.2  2004/03/22 21:59:38  pelle
 * SimpleLedger now passes all unit tests
 * <p/>
 * Revision 1.1  2004/03/22 20:08:24  pelle
 * Added simple ledger for unit testing and in memory use
 * <p/>
 * Revision 1.12  2004/03/22 17:33:02  pelle
 * Added a verified transfer to neuclear-ledger.
 * Added InsufficientFundsException to be thrown if transfer isnt verified.
 * HeldTransfers also are now verified.
 * <p/>
 * Revision 1.11  2004/03/21 00:48:36  pelle
 * The problem with Enveloped signatures has now been fixed. It was a problem in the way transforms work. I have bandaided it, but in the future if better support for transforms need to be made, we need to rethink it a bit. Perhaps using the new crypto channel's in neuclear-commons.
 * <p/>
 * Revision 1.10  2004/01/02 23:18:35  pelle
 * Added StatementFactory pattern and refactored the ledger to use it.
 * <p/>
 * Revision 1.9  2003/12/31 00:39:05  pelle
 * Added Drivers for handling different Database dialects in the entity model.
 * Added BookBrowser pattern to ledger, simplifying the statement writing process.
 * <p/>
 * Revision 1.8  2003/12/26 22:50:52  pelle
 * Mainly fixes to SQLLedger to support the schema generated by the new EntityModel
 * <p/>
 * Revision 1.7  2003/12/24 00:24:33  pelle
 * Created a kind of poor man's version of ofbiz.org's EntityEngine. It doesnt use xml to configure it, but code.
 * Should mainly be used to create tables. Can also insert rows, but hasnt been thoroughly tested.
 * At some point I will improve that part and add some kind of smart querying engine to it. Similar to EntityEngine. But I dont
 * need that myself right now.
 * SQLLedger now uses this to create its tables. It is not fully working yet, but will be shortly.
 * <p/>
 * Revision 1.6  2003/12/03 23:21:43  pelle
 * Got rid of ofbiz support. Way over the top for our use.
 * <p/>
 * Revision 1.5  2003/11/21 04:43:21  pelle
 * EncryptedFileStore now works. It uses the PBECipher with DES3 afair.
 * Otherwise You will Finaliate.
 * Anything that can be final has been made final throughout everyting. We've used IDEA's Inspector tool to find all instance of variables that could be final.
 * This should hopefully make everything more stable (and secure).
 * <p/>
 * Revision 1.4  2003/11/11 21:17:32  pelle
 * Further vital reshuffling.
 * org.neudist.crypto.* and org.neudist.utils.* have been moved to respective areas under org.neuclear.commons
 * org.neuclear.signers.* as well as org.neuclear.passphraseagents have been moved under org.neuclear.commons.crypto as well.
 * Did a bit of work on the Canonicalizer and changed a few other minor bits.
 * <p/>
 * Revision 1.3  2003/10/29 21:15:13  pelle
 * Refactored the whole signing process. Now we have an interface called Signer which is the old SignerStore.
 * To use it you pass a byte array and an alias. The sign method then returns the signature.
 * If a Signer needs a passphrase it uses a PassPhraseAgent to present a dialogue box, read it from a command line etc.
 * This new Signer pattern allows us to use secure signing hardware such as N-Cipher in the future for server applications as well
 * as SmartCards for end user applications.
 * <p/>
 * Revision 1.2  2003/10/28 23:43:15  pelle
 * The GuiDialogAgent now works. It simply presents itself as a simple modal dialog box asking for a passphrase.
 * The two Signer implementations both use it for the passphrase.
 * <p/>
 * Revision 1.1.1.1  2003/09/20 23:16:21  pelle
 * First revision of neuclear-ledger in /cvsroot/neuclear
 * Older versions can be found /cvsroot/neuclear
 * <p/>
 * Revision 1.15  2003/08/08 23:05:12  pelle
 * Updated to use PicoContainer.
 * This will be made more elegant as we go along.
 * <p/>
 * Revision 1.14  2003/08/06 19:16:32  pelle
 * Updated various missing items.
 * <p/>
 * Revision 1.13  2003/08/06 16:41:22  pelle
 * Fixed a few implementation bugs with regards to the Held Transactions
 * <p/>
 * Revision 1.12  2003/08/01 21:59:47  pelle
 * More changes to the way helds are managed.
 * <p/>
 * Revision 1.11  2003/07/30 16:27:55  pelle
 * Final fixes for unit tests.
 * Renamed implementHeld() => complete()
 * Had to override reverse() to make complete work.
 * Note: had to "fix" a unit test to make SimpleLedger pass
 * I dont have time to fix it at the moment. I suspect its simple.
 * <p/>
 * Revision 1.10  2003/07/29 22:57:50  pelle
 * New version with refactored support for HeldTransactions.
 * Please note that this causes a sql exception when adding held_item rows.
 * <p/>
 * Revision 1.9  2003/07/28 21:29:15  pelle
 * Changed a few things in the LedgerFactory.
 * Still not quite there yet.
 * <p/>
 * Revision 1.8  2003/07/23 17:19:26  pelle
 * Ledgers now have a required display name.
 * <p/>
 * Revision 1.7  2003/07/21 19:43:39  pelle
 * Moved the Revisioning tests into the main AbstractLedgerTest.
 * Fixed the getTransactionTime method in SQLLedger.
 * <p/>
 * Revision 1.6  2003/07/21 18:35:15  pelle
 * Completed Exception handling refactoring
 * <p/>
 * Revision 1.5  2003/07/21 17:47:37  pelle
 * Held transactions now work in SQL
 * <p/>
 * Revision 1.4  2003/07/18 20:27:39  pelle
 * *** empty log message ***
 * <p/>
 * Revision 1.3  2003/07/17 22:33:57  pelle
 * Fixed various problems. Lets see how we do. I waiting for the autoincrement to work on the entries.
 * <p/>
 * Revision 1.2  2003/07/16 18:08:49  pelle
 * Adding the first parts of sql support.
 * <p/>
 * Revision 1.1  2003/01/25 19:14:47  pelle
 * The ridiculously simple SimpleLedger now passes initial test.
 * I've split the Transaction Class into two sub classes and made Transaction  abstract.
 * The two new Transaction Classes reflect the state of the Transaction and their methods reflect this.
