Revision 1.1  2004/04/05 16:31:42  pelle
Created new ServiceBuilder class for creating services. A service is an identity that has a seperate service URL and Service Public Key.

Revision 1.10  2004/04/02 16:58:54  pelle
Updated Asset and Asset Builder with semi fully featured functionality.
It now has Issuer, Service etc.

Revision 1.9  2004/01/05 23:47:09  pelle
Create new Document classification "order", which is really just inherint in the new
package layout.
Got rid of much of the inheritance that was lying around and thought a bit further about the format of the exchange orders.

Revision 1.8  2004/01/03 20:36:25  pelle
Renamed HeldTransfer to Exchange
Dropped valuetime from the request objects.
Doesnt yet compile. New commit to follow soon.

Revision 1.7  2003/12/19 18:02:35  pelle
Revamped a lot of exception handling throughout the framework, it has been simplified in most places:
- For most cases the main exception to worry about now is InvalidNamedObjectException.
- Most lowerlevel exception that cant be handled meaningful are now wrapped in the LowLevelException, a
  runtime exception.
- Source and Store patterns each now have their own exceptions that generalizes the various physical
  exceptions that can happen in that area.

Revision 1.6  2003/11/22 00:22:28  pelle
All unit tests in commons, id and xmlsec now work.
AssetController now successfully processes payments in the unit test.
Payment Web App has working form that creates a TransferOrder presents it to the signer
and forwards it to AssetControlServlet. (Which throws an XML Parser Exception) I think the XMLReaderServlet is bust.

Revision 1.5  2003/11/21 04:43:04  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).

Revision 1.4  2003/11/12 23:47:04  pelle
Much work done in creating good test environment.
PaymentReceiverTest works, but needs a abit more work in its environment to succeed testing.

Revision 1.3  2003/11/10 17:42:07  pelle
The AssetController interface has been more or less finalized.
CurrencyController fully implemented
AssetControlClient implementes a remote client for communicating with AssetControllers

Revision 1.2  2003/11/09 03:26:47  pelle
More house keeping and shuffling about mainly pay

Revision 1.1  2003/11/08 01:39:58  pelle
WARNING this rev is majorly unstable and will almost certainly not compile.
More major refactoring in neuclear-pay.
Got rid of neuclear-ledger like features of pay such as Account and Issuer.
Accounts have been replaced by Identity from neuclear-id
Issuer is now Asset which is a subclass of Identity
AssetController supports more than one Asset. Which is important for most non ecurrency implementations.
TransferOrder/Receipt and its Exchange companions are now SignedNamedObjects. Thus to create them you must use
their matching TransferOrder/ReceiptBuilder classes.
PaymentProcessor has been renamed CurrencyController. I will extract a superclass later to be named AbstractLedgerController
which will handle all neuclear-ledger based AssetControllers.

Revision 1.3  2003/11/06 23:47:43  pelle
Major Refactoring of CurrencyController.
Factored out AssetController to be new abstract parent class together with most of its support classes.
Created (Half way) AssetControlClient, which can perform transactions on external AssetControllers via NeuClear.
Created the first attempt at the ExchangeAgent. This will need use of the AssetControlClient.
SOAPTools was changed to return a stream. This is required by the VerifyingReader in NeuClear.

Revision 1.2  2003/10/25 00:38:43  pelle
Fixed SmtpSender it now sends the messages.
Refactored CommandLineSigner. Now it simply signs files read from command line. However new class IdentityCreator
is subclassed and creates new Identities. You can subclass CommandLineSigner to create your own variants.
Several problems with configuration. Trying to solve at the moment. Updated PicoContainer to beta-2

Revision 1.1  2003/10/03 23:48:29  pelle
Did various security related updates in the pay package with regards to immutability of fields etc.
AssetControllerReceiver should now be operational. Real testing needs to be done including in particular setting the
private key of the Receiver.
A new class TransferGlobals contains usefull settings for making life easier in the other contract based classes.
TransferContract the signed contract is functional and has a matching TransferRequestBuilder class for programmatically creating
TransferRequests for signing.
TransferReceiptBuilder has been created for use by Transfer processors. It is used in the AssetControllerReceiver.
