Mzs Schema Changes:
- Formerly: The mzs:DeliveryNotificationType is a choice between
Success And Error; Change: Wrap choice in a sequence. Reason: msg
2.0.0 adds fields that fit best in this sequence. Adding new fields
to Success or Error duplicates code, whereas adding it to the base
type (which is MessageType) also affects mzs:DeliveryRequestStatus.
- Add msg:SenderDetails, ReceiverDetails, user, AdditionalFormat,
NotificationsPerformed; Reason: It was added to zusemsg 2.0.0.
|
|
MZS Schema Change:
- Add configuration for ForwardResponseToServiceSink
(add parameters in mzs:DeliveryRequest/Config)
- Add sink configuration in application.yaml, convert from Spring
Environment to ConfigType, and merge ConfigTypes.
- Validate sink configuration completeness.
Contract added:
- Add contract mzs2app.wsdl: This contract specifies how
mzs:DeliveryRequestStatus' and mzs:DeliveryNotifications are
forwarded to the sender application.
- Implement "ForwardResponseToService" Sink.
- Add and implement MsgResponse.sendToMzsClient() : This is a somewhat
unfortunate solution because, intuitively, sending should be done by
it's caller, the "ForwardResponseToService"-sink. However, this
solution prevents differences between msg:DeliveryRequestStatus and
msg:DeliveryNotification (and code that needs to handle differences,
i.e. sending) from sprawling outside of the respective MsgResponse
derivatives. We move the entire "send" process into MsgResponse to
prevent a hard-to-maintain "if type == notification then do x else
to y" construct in ForwardResponseToServiceSink. Otherwise,
introducing the MsgResponse wrapper was pointless.
|
|
- Fix in ConfigUtil: SaveResponseToFile boolean would override
LogResponse configuration (Copy Paste Error).
|
|
- MZS Schema Change: Add "MsgResponseSinks" element to
mzs:DeliveryRequest/Config that allows sender to configure how
MsgResponses should be archived.
- ConfigUtil: Interpret MsgResponseSink parameters from Spring
Environment and merge with ConfigType.
- MsgResponseBackend: Send responses to sinks according to
MsgResponseSinks in Config
- application.yaml: Add MsgResponseSinks parameter to configuration.
- Uncouple Sink implementations from java.util.function.Function,
because the sink interfaces are going to differ and there is no need
to unite them under one interface.
- Add and test LogResponseSink, which logs responses to it's logger.
- MsgResponse: Add JAXB getter for response. Reason: Can be passed to
marshaller.
|
|
|
|
- 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.

TnvzHelper Fixes
- Handle additional edge cases.
- Mzs:Schema Change: Eliminate PreAdviceNote redundancy by removing it
from mzs:DeliveryRequest/TnvzMetaData; PreadviceNote is already in
the Receiver element. Update TnvzHelper accordingly.
- Implement and integrate tnvz completeness check into
DeliveryRequestAugmenter to ensure that, after augmentation, tnvz
can be performed.
Refactor mzs:DeliveryRequest Validation:
- Before: Validating, merging and generatig ConfigType in ConfigUtil.
- Change: Need to add validation of DeliveryRequest (Reason: For
performing Tnvz Requests, the DeliveryRequest needs to be in a
consistent state).
- Problem: DeliveryRequest validation does not fit into ConfigUtil.
- Solution: Put validation of DeliveryRequest and Config into new
Component "MzsValidation".
|
|
- 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.
|
|
- Print a big scary warning message for everyone who enables "trustAll"
- Test TrustAll and LaxHostNameVerification
- Describe test case requirements and add key material needed to run
these test cases.
|
|
- Refactor: Get rid of MsgClient, because MsgClientFactory can do all the work.
- Add Connection Timeout and Request Timeout (Policies of HTTP Client)
to mzs:DeliveryRequest/Config and application.yaml.
- Update readme: Add JDK 12 Requirement
|
|
- Switch to java 12 for now. Reason: Bug [1] in JDK 11 (up to
jdk-11+28) impairs SSLHandshake ("Unsupported Operation Exception"),
but was fixed in Java 12.
- Set HTTP policy to infinite.
- Fix key/truststore path resolution
- Fix NPE in ConfigUtil.merge
- Rearrange application.yaml to include two config profiles (one with
and one without SSL for the msg client).
- Add key material for testcases (Note: expires: May 2 14:47:08 2020 GMT)
- Update MsgClient Testcases
[1] https://bugs.openjdk.java.net/browse/JDK-8214098

- 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.

- Interpret `ISignatureVerificationService` response properly (by
following security layer spec [1] and moaspss handbook [2]).
- Add config flag `moa.spss.is-manifest-check-active`
- Change SignatureVerifier Interface: Remove @return boolean, just
throw an exception when a validation error occurs. Reason: In case
the signature cannot be validated, the application always needs the
reason for the validation error, which requires the verifier to
throw an exception. In turn, the only valid return value for
`verify()` becomes `true`, which can be omitted at that point.
- Add testcase for verifying a valid enveloped xml signature
- Remove Certificates that are not needed.

Fixing "ASN.1 creation error: iaik.asn1.CodingException: Length: Too
large ASN.1 object: 109"
- Set fallback value ('jks') for system property
'javax.net.ssl.keyStoreType' and 'javax.net.ssl.trustStoreType'. If
system property is not defined, MoaSigConfig falls back to value
from spring environment. Reason: Without this property explicitly
set to JKS, the inclusion of eaaf-components-moa-sig-lib breaks the
HTTP client builder and the ASN.1 creation error arises. See [1] for
explanation.
- Why fall back: Allows a user to configure these parameters via
command line, but gives meaningful defaults in case of absent
command line properties. Furthermore, these parameters can be configured via
application.yaml or .properties.
Others:
- Set fallback value for system property
'moa.spss.server.configuration'. If system property is not defined,
fall back to value from spring environment. Reason: Allows a user to
configure these parameters via command line while providing
meaningful defaults in case of absent command line properties.
- Add switch 'moa.spss.is-active' to enable / disable signature verification.
- Change log levels of at.gv.* and iaik.* packages to INFO
- Add default certstore (copied from EAAF Components).
- Add mzs root certificate to cert- and truststore.
- Update readme's installation requirements and guide.
Refactor:
- Extract public interface of SignatureVerification class.
- Rename trustprofile folder.
[1] Why eaaf-components-moa-sig-lib breaks HTTP client:
- Including eaaf-components-moa-sig-lib includes IAIK's jca/jce and
xsect, which in turn injects the iaik provider for cryptographic
operations and its own key store (iaik.pkcs.pkcs12.PKCS12KeyStore).
- The Apache HTTP client builder will ask for a
java.base/javax.net.ssl.SSLSocketFactory because it creates an SSL
context, even if the connection runs without SSL.
- Somewhere down the stack, this will trigger the TrustStoreManager to
hand over the systems default trust store (a JKS file) to IAIK's
PKCS12KeyStore. This happens if the type properties of the trust
stores are not set.
- Oracle relaxed a precondition of this trust store (somewhere in
between Java 8 and 11) in the TrustStoreManager: Formerly, the trust
store was a JKS object. Now, the trust store can be both a JKS and a
PKCS12 object. The TrustStoreManager expects the key store to handle
both types, and Oracle's keystore does. However, IAIK's key store
cannot handle a JKS object, but since eaaf-components-moa-sig-lib
was included, the IAIK key store comes first.
- PKCS12KeyStore expects a PKCS12 file but receives a JKS file ->
Parser Error.

- Verify signature via ISignatureVerificationService.
- Override System Property moa.spss.server.configuration via spring's
environment (Reason: can configure path to moa SPSS config file via
application.yaml & moa SPSS needs this parameter to find the config
file)
- Setup test configuration directory for moaspss in
src/main/resources/moa-spss
- Readme: Explain how to install moaspss' dependencies into local
repository.
|
|
- Reduce logger output of all contexts to ERROR and WARN Statements;
Moazs can log to INFO. Reason: Including moa-sig causes lots of
DEBUG / TRACE logging .
- Add Repository that points to file://${basedir}/repository.
- Add guide how to compile project (I dont check moa-sig depenendcies
into repository but explain how to retrieve dependencies manually in
readme.md.)

- 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.

make a client. Make request and config private fields.
- Add configuration parameters to application.yaml.
- Init SSL client auth testcase, but dont include in testsuite because
it aint working yet.

ConfigProfileGenerator:
- Cancel startup if default Config profile is incomplete.
- Add property flag
'verify-completeness-of-default-delivery-request-configuration',
which allows admin to disable completeness check. In that case, just
log a warning if the default profile is incomplete.
Augmenter:
- Ensure that after merging the config is complete (or throw an
exception otherwise).
- Refactor: Move ConfigProfileValidator from ConfigProfileGenerator to
dedicated "ConfigProfileValidator" class; Reason: Augmenter needs to
check completness of at-runtime-compiled configuration.
- Refactor: Rewrote code for better readability.
Others
- NPE Fix in ConfigProfileMerger: If FallbackConfigProfile/Server is
empty, use PrimaryProfile/Server.
|
|
Config Profile Integration:
- Merge generated Configs from ConfigProfileGenerator with the default
Config; Reason: Merging profile Configs with default Config asap
ensures that profile Configs are "as complete as possible" while
allowing profile Configs to "on-demand"-override values from the
default Config.
- Adapt Augmenter to work with Config profiles: Select a Config on the
basis of on msg:DeliveryRequest/Config/ProfileId, fall back to 'default'
Config.
- Schema change: Make ProfileID optional.
Refactoring:
- Move Config-merging code from Augmenter into dedicated
'ConfigProfileMerger' class.
- ConfigProfileGenerator: Clarify stream pipeline and comply with
coding standard w.r.t. constant members.
- Add Augmenter test cases for profile selection.
|
|
Augmenter
- Replace default Config Profile with map of Config Profiles. Now,
Augmenter can choose a config profile at runtime and augment it.
- Move Augmenter to sub package.
WIP
- Implement ConfigProfileGenerator, which retrieves Config profiles
from Spring Environment and returns an easy-to-use map with
profiles that is keyed with profile id's.
- Replace application.properties with application.yaml.
- Remove Augmenter test cases: They need to be adapted.
|
|
- Rewrite DeliveryRequestAugmenter to allow per-field-overriding of
configuration parameters and add test suite.
- Mzs schema change: Move DeliveryRequest/Server into
DeliveryRequest/Config; Reason: DeliveryRequest/Config contains all
parameters exclusively needed by moazs to execute the delivery
request. The msg's server url belongs to this set of parameters.
- WIP: Add prototype implementation of MsgClient and move MsgClient to
dedicated package.
- Refactor: move TnvzClient to dedicated package.
|
|
|
|
- Implement and test conversion from mzs:DeliveryRequest to
msg:DeliveryRequest with the "convert-pojos-by-hand"-strategy.
Reason: The chosen strategy benefits from JAXB's strong typing,
which is useful in this scenario: Differences between msg and mzs
are nuanced and easy to overlook. The chosen strategy is,
unfortunately, verbose and could become expensive to maintain.
- Update SameThreadDeliveryPipeline: Integrate tnvz query, conversion,
and msg query.
- Add MsgClient stub.
tnvz:
- Change TnvzClient stub interface.
- Implement mimetype mismatch check from tnvz Response.
- Put p:Identification from tnvz response into msg:DeliveryRequest.
MZS Schema changes:
- Replace DeliveryRequest/Sender/Person with CorporateBody (because
thats the only sender that is allowed by zusemsg) and add a
SenderProfile choice.
- Add ID Attribute to DeliveryRequest/Sender because
msg/DeliveryRequest/Sender/AbstractSenderPersonType also has an id
attribute.
- Remove PersonDataType because it's dead code.
|
|
|
|
Add Optional "Config" to MZS Schema:
- Add mzs:DeliveryRequest/Config Element with a
"PerformQueryPersonRequest" node
- The config element contains parameters that are interpreted by
moa-zs and not forwarded to the ZD
- The boolean PerformQueryPersonRequest tells moa-zs if moa-zs should
perform a QueryPersonRequest towards the TNVZ.
- If config is missing, moa-zs augments the delivery request with
parameters from the app's configuartion or the default configuartion
Other Changes:
- Validate and augment incoming requests with the
DeliveryPreprocessor.
- Add stub for TlnvzClient.
- Remove some leftover ObjectFactory imports (because of the builder
they are not needed anymore)
Fixes
- Fixed incorrect API usage of Messageformat.format: format string
needs an index.
pom.xml
- Add Hamcrest Dependency (for writing more expressive tests)
- Add copy constructor to JAXB Builder
Testing
- Test validation of incoming request
- Refactor testcases to improve readability
|
|
- Change app2mzs interface: output message from
app2mzs:DeliveryRequest was app2mzs:DeliveryResponse, now its
msg:DeliveryRequestStatus. Reason: ZD returns
msg:DeliveryRequestStatus which is signed. Moazs does not convert
msg:DeliveryRequestStatus into app2mzs:DeliveryResponse because the
conversion woudl break the signature.
- App2MzsService: Make beans final and inject them with constructor;
Refactor DeliveryRequestHandler into App2MZSService.
- DeliveryPipeline: Add Interface and a "SameThreadImplementation"
that executes the pipeline in the same threat and can be used in
single mode.
- DeliveryRepository: Augment interface for storing and retrieving
request status objects; Add in-memory-implementation for status objects.
- Utils: Add helper function for coalescing multiple values
|
|
- Deployer can choose which implementation to use (by activating
- corresponding profile)
- Add guava dependency
- Extract DeliveryRequestRepository to Interface
- Implement InMemory Repository using guava's cache

- Connect to Redis server and implement RedisRepository
- Add redis dependencies (spring-boot-starter, jedis, apache commons
io). Latter dependencies are apparently needed and not included in
the sprint-boot-starter; See
https://github.com/spring-projects/spring-boot/issues/5718 and
https://www.concretepage.com/questions/599
- Connect DeliveryRequestHandler to RedisRepository
- Rewrote Marshalling: replace JaxbContext with spring-oxm
JaxbMarshaller
- Catch and log all exceptions in App2MZSService; Former: certain
exceptions would go unnoticed, e.g. ConnectionRefused

|
- Remove MZSDreq/Sender/ConfirmationAddress (because its already
Available in Sender/{WebserviceURL,EmailAddress})
- Simplify MZSDReq/Receiver (no actual schema change, just
refactoring)
- Remove XML Payload (because this delivery method does not exist in
zusemsg)
- Simplify Payload Schema and adapt it to zusemsg:Attachment
- Remove DayOfBirthType (because dead code)
- Metadata: replace mzs definition of metadata with reference to
msg:Metadata. Reason: Both interfaces work the exact same way so
there is no reason in not reusing the interface. Using the same
interface definitions does not affect the integration effort for app
developers, because the msg:metadata changed quite drastically and
app developers will need to integrate these changes anyways. The
changes in zusemsg:Metadata are so invasive that MOAZS cannot
prevent them from propagating into the app2mzs interfaces. A benefit
from reusing the msg:MetaData interface is that there will be less
types, less duplicate code, less repetition, and
therefore cleaner and easier to maintain.
