Jersey 3 with CDI Weld 4 instead of HK2

I have a small JAX-RS (Jersey 3.0.1) API running in a standalone Jetty 11 but want to use Weld 4.0.0 instead of HK2. The Jetty bootstraps the Weld context properly (Jetty module ci-decorate was installed as described in the Weld documentation)

WELD-ENV-001212: Jetty CdiDecoratingListener support detected, CDI injection will be available in Listeners, Servlets and Filters.

When it comes to call the API endpoint an exception occurs:

WARNING: The following warnings have been detected: WARNING: Unknown HK2 failure detected:

My dependencies in the pom.xml look as follows:

        <dependency>
            <groupId>org.jboss.weld.servlet</groupId>
            <artifactId>weld-servlet-core</artifactId>
            <version>4.0.0.Final</version>
        </dependency>
        <dependency>
            <groupId>jakarta.servlet</groupId>
            <artifactId>jakarta.servlet-api</artifactId>
            <version>5.0.0</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>jakarta.ws.rs</groupId>
            <artifactId>jakarta.ws.rs-api</artifactId>
            <version>3.0.0</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.containers</groupId>
            <artifactId>jersey-container-servlet</artifactId>
            <version>3.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.inject</groupId>
            <artifactId>jersey-hk2</artifactId>
            <version>3.0.1</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.ext.cdi</groupId>
            <artifactId>jersey-weld2-se</artifactId>
            <version>3.0.1</version>
        </dependency>

For the Weld context there exists an empty beans.xml in folder webapp/WEB-INF/beans.xml declared with bean-discovery-mode="all". The JAX-RS endpoint class is shown next:

import de.test.weld.service.AddressRepository;
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;

@Path("address")
public class AddressApi {

    @Inject
    private AddressRepository addressRepository;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String getAddress() {
        return "{\"street\": \"" + addressRepository.getStreet(0) + "\", \"postcode\":  \"" +
                addressRepository.getPostcode(0) + "\", \"city\": \"" + addressRepository.getCity(0) + "\"}";
    }
}

The bean AddressRepositoryImpl which I want to inject is annotated with @jakarta.inject.Singleton.

I would appreciate any hint so it works with CDI Weld.

Solution

  • The problem was the wrong dependency

    <dependency>
   <groupId>org.glassfish.jersey.ext.cdi</groupId>
   <artifactId>jersey-weld2-se</artifactId>
   <version>3.0.1</version>
</dependency>

    which exists only for non-JEE environments, i.e. Java Standard Edition (SE) or non-webapps.

    Then the following dependency was still missing:

     <dependency>
     <groupId>org.glassfish.jersey.ext.cdi</groupId>
     <artifactId>jersey-cdi1x</artifactId>
     <version>3.0.1</version>
 </dependency>
