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.
|
|
- 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

- 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.)
|
|
- Refactor MsgClient: Not a Singleton anymore. Use MsgClientFactory to
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.
|
|
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.
