Resteasy | REST and JAXRS - RESTEasy is a JBoss | Telnet library

I'm currently creating an application in Quarkus, using Kotlin. I'm trying to create a simple users endpoint using RestEasy, Panache, and Hibernate. My challenge right now is that exception handling is not correctly done. I want to display a correct and understandable message to the user when the request isn't valid.

This is my UserResource for the createUser POST request:

I created a reactive resteasy service with Quarkus and Mutiny. In POST method I insert object in my PostgreSQL table and get an Uni< id > in return. I need to set this id as part of my Response class which contains f.ex. "id", "errorCode", "errorString" and other variables, but I struggle as id comes as Uni object and I don't know how to extract id from it.

Create method:

I have a microservice in Quarkus which implementing CQRS/Event sourcing using AxonIq Framework. I Already made it using Spring boot and everythings it's ok. I would like to migrate it in Quarkus but I have error during maven compilation probably because the Ioc. When CDI try to create the service I think he can inject Axon CommandGateway and QueryGateway.

I am tring to convert my .jar project into a native image since I need to run it in a device where Java is not supported. For that I installed GraalVM and all the required dependencies, and the native-image build works perfectly (or at least, seems to, as it doesn't give out any errors during the proccess).

The command that I'm using for the build is:

/usr/lib/jvm/graalvm/bin/native-image -jar MyApp.jar MyApp --enable-http --enable-https --no-fallback -H:+ReportExceptionStackTraces

The problem is, when I try to run the native file, I get an exception saying that the log4j class could not be found, and thus I have no application logs during execution:

I'm running Keycloak 15.0.2 in docker (jboss/keycloak:15.0.2) and use Identity Brokering with an external OpenId Connect Identity Provider

When a login is initialized on keycloak the browser is redirected to the external IDP. After authenticated there the browser is redirected to keycloaks broker endpoint /broker/oidc/endpoint?code=xxx

But then Keycloak throws a Exception caused by

Caused by: java.security.NoSuchAlgorithmException: HMACSHA256 Signature not available

Has someone an idea why this is happening? Should this HMACSHA256 algorithm not already be part of the JRE in the docker-container?

Full stacktrace

I've added few attributes for each client in keycloak, and now I need to update the existing client attribute to new value without deleting the client.

I'm attempting to add ActiveMQ Artemis' REST interface to my Docker container, and for that I have been following the official guide. I generate a artemis-rest.war file and move it into my /opt/artemis/web folder. Now when I navigate to http://localhost:8161/artemis-rest/queues/queue_name, I get a 404. When I try to navigate to other resources listed in the /opt/artemis/web like /console/ or /artemis-plugin/ I get at least some sort of a response.

My folder structure looks like this:

I am trying to use the RestResponse object from org.jboss.resteasy.reactive on the return of my application resources since the javax.ws.rs.core.Response doesn't provide the generic type.

I am getting the error when I call this endpoint:

On a JEE project running on Wildfly 15, I am trying to configure the logs to be in json format. Replicating what I have done dozens of times for some more recent Spring Boot projects, I am adding net.logstash.logback:logstash-logback-encoder:6.6 as a runtimeOnly dependency, as I plan to have a logback.xml config file.

When building my application and running the test, adding this dependency makes some tests fail : some controllers are not able to serialize LocalDateTime anymore.
