- Problem: Jaxb + JAVA >= 9 Runtime + Tomcat = ClassNotFoundException:
ContextFactory.
Reason: Apparently, jaxb uses the "wrong" classloader (the system
classloader via the thread classloader) and this classloader does
not know about jaxb api's and implementations at runtime since
oracle decided to move jaxb* out of JRE.
Solution: create a new thread, override the thread's "thread"
classloader with the "class" classloader and do all jaxb
interactions in that thread. See:
https://sjhannah.com/blog/2018/11/21/jaxb-hell-on-jdk-9/
- Move "run jaxb interactions in own thread with class class loader"
code into own component (JaxbClassNotFoundFix,
runInTheadWithClassClassLoader) and wrap ClientFactory and
Marshaller code into the "runInTheadWithClassClassLoader".
- Ensure that app can be deployed in a Tomcat container (by following
this guide: https://www.baeldung.com/spring-boot-war-tomcat-deploy)
|
|
- Reason: Now we can run integration tests without the need to set up
SSL reverse proxy with client certificates.
|
|
|
|
- See https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#build-tool-plugins-maven-packaging
|
|
- Also: Replace local repository with apps.egiz.gv.at/maven
- Update Readme and remove cumbersome "build via local repo" guide.

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.
|
|
- 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.
|
|
- EgovUtils were needed because of DomUtils. Replace it with eaaf
components' DomUtils.
- Add test case to ensure SoapUtils still works as intended. - Remove
unused import statement
|
|
Per default, integration tests are excluded from build. They can be
included with the `-P integration-test` argument.
- Pom: Add maven profile for integration tests.
- Rename integration tests (add `IT` prefix).
- Move Resources into IT* folders.
- Add MsgClientTest to test suite and add assertions to each test case.
|
|
- 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.

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.)
|
|
- 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.
|
|
- Add egovutils dependency (Reason: Need DomUtils to serialize /
unserialize Soap Message via DOMParser)
- Add Incerceptor to MsgClient / -Factory that stores the message
content byte-by-byte in the DeliveryRepository. The format is
required for successfully validating a DeliveryRequestStatus.
- Add SoapUtils, which interacts with byte[] Soap message.
- Add CXFMessageUtils, which interacts with CXF Messages from
interceptor chains.
- Refactor xsd namespaces: Move them out from the PrefixMapper and
into a dedicated class.
|
|
- Remove unused imports, commented code and copy-pasted code
|
|
- 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.

|
- Reason: Redefining mzs packages is not neccessary for zusemsg
related jaxb classes because zusemsg does not rely on mzs.
|
|
- Reason: Improves readability and makes import statetemens shorter
and more consistent
|
|
- App2MZS Server: Instead of generating a DeliveryRequestStatus/Error
Message, we throw an exception. This will generate a SoapFault
(including a 500 http status code), which is more appropriate.
- Fix possible NPE of deliveryRequest.getMetadata().getAppDeliveryID()
by moving appDeliveryID initialization into the TimeOutException catch block
- pom.xml: Remove hamcrest dependency, as not needed for now.
|

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

- Use Immutable-XJC from https://github.com/sabomichal/immutable-xjc
- Update existing JAXB-object manipulations to use the Builder
- Remove jaxbMarshallerTest (as it relies on mutable JAXB interfaces)
Reason for making JAXB objects immutable: I put JAXB objects in the
repository. Depending on the configuration, the repository can be a
simple hashmap; in that case I might end up sharing JAXB objects
between threads. Immutable shared object should make life a little
simpler.

- 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
