- Service Timeout : Add service timeout to mzs schema (DeliveryRequest
/ Config), application.yaml, convert service timeout from spring
environment to Config, and merge service timeouts in Configs.
- Handling of Asynchronous DeliveryRequestStatus: Move "Applying
Response Sinks" from backend into dedicated component
"MsgResponseSinkHub" and integrate SinkHub into MzsService (apply
sinks to asynchronous responses).
- Remove line breaks in SignatureVerifier's log statements.
- Revise documentation of parameters in application.yaml.

Reason: MoaZSException (and: its builder) were used to collect
intermediary results while stepping through the delivery request
backend. These results were needed to generate meaningful responses
towards the sender application in case of error. However, the builder
sprawled over too many interfaces (e.g. DeliveryRequestBackend and
TNVZHelper) and it became difficult to understand from where
intermediary results originated.
Solution: Put MoaZSException on diet:
- Remove all DeliveryAnswer fields from MoaZSException and refactor
code base to ensure that the removed fields get sourced by other
means.
- Remove Builder since amount of parameters is manageable.
Refactor DeliveryRequestBackend:
- Instead of passing down the builder and using MoaZSException as the
only source for intermediary results, we collect available results
at the outermost stack frame (DeliveryRequestBackend.accept) and
only retrieve results via exception if those results appear
somewhere down the stack frame (E.g. PredviceNoteSent). We collect
available results with the "fallbackAnswerBuilder" and switch to the
msg client response, once received.
Refactor MsgResponseBackend:
- Handle cases (response missing, binary response missing) properly.
- Integrate changes from MsgResponse.generateError()
Refactor TVNZHelper:
- Remove MoaZSExceptionBuilder from all interfaces.
Refactor MsgResponse.generateError:
- Change interface such that it's more intuitive.
- Implement NotificationResponse.generateError.
- Implement RequestStatusResponse.generateError.
Others:
- Replace all invocations against MoaZSException.Builder.

- Fix typo in SafeResponseToFileSink.
- MoaZSException: Simplify constructor by replacing lots of arguments
with the builder instance.
- Fix minor codesmells (unused imports, superfluous braces).

- Add zuse2app.wsdl contract.
- Add MsgResponse as an type-agnostic view for DeliveryRequestStatus
and DeliveryNotification messages. Reason: Both DeliveryNotification
and DeliveryRequestStatus messages have similar fields and need to
be treated similarly (e.g.: receive from msg service, store to
repository, verify signature, store to file...). In order to prevent
duplicated code, the wrapper interface provides a type-agnostic view
onto these messages for depending components to operate on.
- Add MsgResponseHandler interface; decides how to process
MsgResponse. Also implement this handler with a multi-threaded
single-node implementation.
- Add MsgResponseSink interface; decides how to archive MsgResponse.
- Implement and test SafeResponseToFileSink.
Change Identifier for MsgResponses:
- Before, DeliveryRequestStatus and DeliveryNotifications had their
own repositories. Now, both types are stored in the same repository
(the MsgResponse repository) to streamline the handling of
MsgResponses. We need to change the identification of MsgReponses,
otherwise the identifiers (AppDeliveryID) clash.
- MsgResponses are not identified by:
<AppDeliveryId>+<typeSpecificSuffix>
- Rewrite StoreSOAPInterceptor to accommodate fact that, both
DeliveryRequestStatus and DeliveryNotification messages have
different IDs upon storage / retrieval.
Restructure packages and components as follows:
- client: All components that are involved when consuming a web service.
- process: "fabric" of MoaZS; contains business logic that
orchestrates back-end tasks of MoaZS's operational services, e.g.:
by processing a delivery request.
- service: Implementation of MoaZS's front-end services.
Refactoring:
- MoaZSException: Remove unused fields. Before: Store mzsrequest,
tnvzresult, msgrequest and msgresult as members. Now: Only keep the
fields that are needed later, e.g for generating a
msg:DeliveryRequestStatus element. Add copy constructor to Builder.
- Put storage of byte[] into a dedicated "BinaryRepository". Reason:
This was useful in a former design. Now it's not really needed
anymore.
- Put "create Endpoint" code into EndpointFactory. Reason: Eliminate
duplicated code when configuring a service.
Testing:
- Activate Stacktraces in surefire.

- Merge TnvzClient and TnvzResultVerifier to TnvzHelper; TnvzHelper
now builds the QueryPersonRequest, sends it to the tnvz port and
evaluates the result.
- Publish some interfaces in Mzs2MsgConverter because they are needed
by TnvzHelper.
- Generalize MsgClientFactory to ClientFactory such that it can be
used to generate arbitrary SOAP clients (e.g. also for tnvz!).
Schema Changes to accomodate Tnvz's QueryPersonRequest:
- Add optional tnvz:AustrianAddressesOnly and optional TnvzMetaData to
mzs:mzs:DeliveryRequest.
Removed Unit Tests:
- Remove subset of SameThreadDeliveryPipeline testcases (mimetype
related) because its logic moved to TnvzHelper.

- Add Component to create SSLContexts with own Key- and trust store.
- Inject SSLContext into HTTP Client.
- Add EAAF-Components Core Dependency, which is needed by
SSLContextCreator (KeyStoreUtils).
Schema Changes in mzs:DeliveryRequest/Config:
- Got Rid of mzs:DeliveryRequest/Config/Server. In mzs 1.4.1,
Server replaces the result of zkopf query person request. Since this
zkopf interface does not exist anymore, Server was removed.
- Add ClientType, which holds all parameters needed to connect to a
service (Url, SSL params, a.o.).
Configuration:
- Add default parameters for SSL Clients in application.yaml.
- Merge default parameters into incoming mzs:DeliveryRequests.
MoaZSException Fixes:
- Remove "Extends throwable" from Builder.
- Add convenient shorthand init method (message, throwable).
Refactor:
- Put "determinePath" to FileUtils.
- Put string related utility functions into StringUtils.

- Ensure proper communication of errors between pipeline and mzs
service by converting MoaZSExceptions into DeliveryRequestStatus
messages.
- Revise MoaZSException: Add optional fields; those fields are a)
helpful to construct meaningful error messages and b) optional
because, depending on where an exception appears, either existent or
non-existent and thus optional. Add inner-class Builder.
- Integrate Signature Verification into pipeline and add Stub for
SignatureVerification.
- Move TNVZResponse's Mimetype check into dedicated class (Reason:
separate abstration layers).
- Update api changes in testcases.

- MZS cant reply with a msg:DeliveryRequestStatusType to a
mzs:DeliveryRequest. Reason: unmarshalling a
msg:DeliveryRequestStatusType with JAXB (after receiving the msg
reply) breaks the signature in msg:DeliveryRequestStatusType. Why?
Because JAXB marshalling tinkers with the namespaces and, as for the
current state of knowledge, we cannot configure the JAXB marshaller
to reconstruct a XML Document byte-by-byte such that a signature
that went through this process can be verified successfully (see [1]).
- For this reason, we revert back to mzs:DeliveryResponse and add new
fields / remove obsolete fields / capture all changes between zusemsg
1.5.3 and zusemsg 2.0.0.
- The easier solution would be to wrap and transmit signed data +
signature in a binary (base64) container, such that apache cxf and
other web service frameworks won't unmarshall them. This doesnt work
because zusemsg 2.0.0 is final.
app2mzs.xsd Changes in Detail :
- Add DeliverySystem, ZSDeliveryID and GZ to MessageType (MessageType
is the base type of DeliveryResponse.Success, -PartialSuccess, and
-Error); Reason: It was added to zusemsg 2.0.0.
- Add SignedDeliveryRequestStatus to MessageType. Reason: If msg
returns signed reply, this element contains the reply as byte[] such
that the signature does not break.
- Add optional PreadvicenoteSend to ErrorType (because it was added in
zusemsg 2.0.0)
- Remove MZSDeliveryID from every instance because this ID does not
exist anymore (moa zs does not maintain requests in a database).
- Remove DocumentReference from ErrorType as it was removed from
zusemsg 2.0.0.
- Remove DeliveryConfirmation as node in DeliveryNotificiationType
because it does not exist anymore in zusemsg 2.0.0;
DeliveryConfirmation is also obsolete because all msg' replies are
signed and need to be transferred to the sender application as a
byte[], which is done by SignedDeliveryRequestStatus node in
MessageType.
- Remove DeliveryStatement as node in DeliveryNotificiationType
because it does not exist anymore in zusemsg 2.0.0.
Other Changes
- Adapt codebase: MzsService returns mzs:DeliveryResponse.
- Implement conversion from msg:DeliveryRequestStatus to
mzs:DeliveryResponse.
- Add store / retrieve interface to DeliveryRepository that stores
signed delivery request statuses as byte[].
Temporary Changes
- Disable integration tests which have external dependencies.
