When MicroProfile LRA coordinator and participants run on different Docker containers, it is needed to define a custom URI for each participant.
Otherwise the LRA coordinator tries to call participant compensate/complete APIs by referring them with "localhost" based URI.
Is it possible, on WildFly environment, to define a custom URI for a participant? And ingeneral is it possible to define a how participants can register with any LRA?...
ANSWERAnswered 2022-Apr-12 at 12:03
By default, the participant endpoints are derived from the caller information provided in the JAX-RS
UriInfo class. This class contains the base URI of the caller of the participant. The idea is that coordinator should be able to call the participant on the same URI as the original request to the participant came in.
I've created a simple docker image https://hub.docker.com/repository/docker/xstefank/uriinfo-wildfly which will on path
/uriinfo/ping return the the base URI that will be used for participant URLs.
Calling this locally gives you -
Base URI is http://localhost:8080/uriinfo/ which is expected called from the local machine. Deploying this image to OpenShift/Kubernetes and exposing a route for this application gives you
Base URI is http://uriinfo-wildfly-testing.6923.rh-us-east-1.openshiftapps.com/uriinfo/. And finally, calling it from a different pod deployed in the same project gives you
Base URI is http://uriinfo-wildfly:8080/uriinfo/ which corresponds to the actual calls:
Quarkus' Kafka-Streams extension provides a convenient way to start a pipeline. Necessary configuration options for the stream application, e.g.,
quarkus.kafka-streams.bootstrap-servers=localhost:9092 must be inserted in the
application.properties file for the encompassing project.
Quarkus also provides a pass-through option for a finer configuration. The documentation states:
All the properties within the kafka-streams namespace are passed through as-is to the Kafka Streams engine. Changing their values requires a rebuild of the application.
With that, we can for example pass-through a custom timestamp extractor (or any other configuration property that related to the streams configuration)...

You can just pass it using standard configuration for consumers and producers, prefixed with kafka-streams:
I'm just starting to explore openliberty, so maybe there is something trivial I did not see.

For the time being (see environment info in the question)
mvn liberty:dev throws an error if
maven.compiler.target is used together with
maven.compiler.release even if the version numbers are aligned. So you either have to use
If you are working in a maven-multi-module project where the above properties were defined in parent modules you can workaround this issue by overriding the properties appropriately.
i'm currently upgrading from Wildfly 20 to Wildfly 26. The
standalone.xml doesn't start, because of an Injection of
MetricRegistry and the newly missing
microprofile.metrics-smallrye-extension (already described under: MicroProfile Metrics do not show custom metrics on Wildfly 25).
But if i start the
standalone-microprofile.xml or add the extensions (see CLI-commands below), i ran into the same error.
Maybe the Keycloak-Integration-Workaround is conflicting. The Wildfly-internal OIDC adapter is actualy not working in bearer-only-mode. So i installed the current keycloak-client (
keycloak-oidc-wildfly-adapter-16.1.1) an the workaround (see as last code-template).

Oh i spend a couple of hours to get rid of this problem.. but only minutes after writing this post, i found the "bad guy".
The Microprofile Version 3.3 (on Wildfly 20) ignored annotations (like
@Timed) at interface-methods. The new Version 4.1 (Wildfly 26) regards them..
pretty easy, afterwards :)
If you have more than one WAR deployed on your Wildfly and one of them is using the public API of an other one, then you'll run into problems with hot-deployments.
I assume, in my case it occurs because i have placed the
Timed-annotation at the implementation-class and not at the interface, that is used as ResteasyClient-proxy. Every time i deploy the depending WAR after the rest-api-defining WAR, i got an exception:
no metric mapped.
A redeployment of the rest-api-defining WAR fixes this issue :)

The problem here is that the API and SPI bundles that start with io.openliberty have not been publishing to DHE and maven as part of the Liberty publishing tasks that run when a new version is released. We are looking to have this resolved with 188.8.131.52 which is scheduled to be available tomorrow if we don't run into any additional snags and the io.openliberty publishing goes well.
I have a maven project with two modules : core and webapp. The webapp module is a war file to be deployed to wildfly. It has a dependency to the core module.
I can run

mvn wildfly:deploy in the webapp directory I get :

You are using Java 16 (as shown in the log file) with Maven. In this case, you should use TomEE in version 8.0.9 as this release contains important fixes regarding illegal reflective access (due to the use of Unsafe for proxy creation) in higher versions of Java. You find some details in https://issues.apache.org/jira/browse/TOMEE-3795
It looks like you are using a lower Java version for running your standalone TomEE deployment, which works as it isn't as restrictive as newer Java versions.
Side Note: Java 16 is end-of-life and you should better switch to Java 17.

ANSWERAnswered 2022-Feb-07 at 17:56
It looks like there was a bug filed for this, but it was fixed in WildFly 25. That said I do not see the reference in the default README.
That said it does require the
standalone-microprofile.xml. You can also add the subsystem with CLI to
standalone.xml and runt it that way as well. The following CLI commands will add the
microprofile-health-smallrye to any configuration you start with that does not already include the subsystem.

I changed other stuff except the Quarkus baseline, so I don't know for sure the update is the sole cause....
ANSWERAnswered 2022-Jan-18 at 15:51
This is not caused by the update, Quarkus 2.6.2.Final did not change anything regarding the fault tolerance stuff.
To facilitate negative testing, you can inject
CircuitBreakerMaintenance and reset all circuit breakers in the application using
resetAll (see https://smallrye.io/docs/smallrye-fault-tolerance/5.2.1/usage/extra.html#_circuit_breaker_maintenance).
Alternatively, there's a configuration property that disables all fault tolerance except fallbacks:
MP_Fault_Tolerance_NonFallback_Enabled (see https://download.eclipse.org/microprofile/microprofile-fault-tolerance-3.0/microprofile-fault-tolerance-spec-3.0.html#_disable_a_group_of_fault_tolerance_annotations_on_the_global_level).
I'm a C developer who needs to create a basic async REST server (synchronous version works fine) in Java using the Microprofile (Helidon MP) framework. Here is my strategy to do this:
The client should do the POST call and provide JSON objects that the POST endpoint will receive. Then, the POST Endpoint method will call a business logic that should do stuff with the received JSON objects. This logic must be run asynchronously. POST should immediately return 202 Accepted. The client should check for async task completion status using a GET request (simple pooling style).
Should POST return a URI that the GET call will use? How? This GET should also provide the percentage of the task completion if the task is in progress. Finally, if the business logic is done, the GET should return the result.
I have a little previous experience with async Java, but no experience with async in this Microprofile/Java EE/Jakarta or whatever it is. I tried several different approaches (AsyncResponse, CompletitionStatus, etc.) to write this code (async POST Method) but nothing seems to be working. The skeleton of the POST functions looks like this:...
ANSWERAnswered 2021-Dec-23 at 22:10
So, first things first. To run things asynchronously Jakarta EE has the annotation
@Asynchronous. So, create a CDI bean with
@RequestScoped, and put there your business method annotated with
@ApplicationScoped CDI annotation to your JAXRS service so you can inject ypur business bean.
Then, for monitoring the task, you have a couple of possibilities.
If you keep the state in a database you just make the
@GETmethod to check the state in the database. But I asume this is not your case.
If the first approach doesn't fit then you have to keep the state of the different inProgress tasks somehow. I would have another
@ApplicationScopedCDI bean for that. This would contain a
ConcurrentHashMap, with a
UUIDas the key, and as the value an Object of your own that contains the current state of any specific async job.
UUID has to be generated in the
@POST method, and sent as a parameter to the
@Asynchronous, method. This way the
@POST method can return the
UUID, which will be used then in the
@GET to request the state of the task (querying the
So the application-wide async tasks state holder should be something like this

You can use microprofile like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the microprofile component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
