JAX-RS resource returns HTTP/1.1 404 Not Found after Jakarta migration

I've upgraded an 'old' (was working) EE Application with JSON which did work with 'javax'. Now on EE 10.x & Jakarta.

implementation("com.google.code.gson:gson:2.11.0")

Using:

import com.bewherewhen.ejb.UsersJSONEJB;

import jakarta.inject.Inject;
import jakarta.inject.Named;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
import jakarta.ws.rs.core.Response;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Named
@Path("/")
public class UsersJSONController {
    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("/get-all-users")
    public Response getAllUsersJSON() {
        LOGGER.info(">>>>> UsersJSONController getAllUsersJSON .....");

        String json = usersJSONEJB.getAllUsersJSON();
        LOGGER.info(">>>>> 1.6 UsersJSONEJB getAllUsersJSON = {}", json);

        return Response.ok(json, MediaType.APPLICATION_JSON).build();
    }
}

If I run 'curl' I get:

curl -v http://127.0.0.1:8080/get-all-users/
*   Trying 127.0.0.1:8080...
* Connected to 127.0.0.1 (127.0.0.1) port 8080

TIA.

Solution

  • I added 'ApplicationPath/ApplicationConfig' on 'javax':

    package com.bewherewhen.webservices;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("beWhereWhen")
public class ApplicationConfig extends Application {
    public ApplicationConfig() {
    }
}

    Run:

    curl -v http://localhost:8080/BeWhereWhen/beWhereWhen/get-all-users/

    Gives 'HTTP/1.1 200 OK":

    * Host localhost:8080 was resolved.
* IPv6: ::1
* IPv4: 127.0.0.1

    However unable to create a version for Jakarta EE 10/11:

    import jakarta.faces.application.Application;
import jakarta.ws.rs.ApplicationPath;

    Error with:

    error: ApplicationConfig is not abstract and does not override abstract method getValidatorIds() in Application

    Unable to deploy with "jakarta.ws.rs" on EE 10/11. Selected Methods to Implement on WildFly 33.0.0. Can any suggestion or examples?

    Fixed:

    import jakarta.ws.rs.ApplicationPath;
import jakarta.ws.rs.core.Application;
import java.util.Set;

@ApplicationPath("beWhereWhen")
public class ApplicationConfig extends Application {
    public ApplicationConfig() {
        // Default constructor
    }

    @Override
    public Set<Class<?>> getClasses() {
        // Return a non-null Set of resource and provider classes
        return Set.of(); // Replace with actual resource classes if any
    }

    //@Override
    public ActionListener getActionListener() {
        // Implement the method for the action listener
        return new MyActionListener(); // Replace with your actual listener implementation
    }

    // Define MyActionListener or replace with your actual implementation
    private static class MyActionListener implements ActionListener {
        @Override
        public void performSomeAction() {
            // Implement the action listener's functionality here
        }
    }

    // Define an interface if it's not already defined.
    // This is just an example. Replace it with the actual interface definition.
    private interface ActionListener {
        void performSomeAction();
    }
}
