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

Using:
- macOS Sonoma 14.6
- gson 2.11.0
- curl 8.9.1
- WildFly Distribution – 33.0.0.Final
- Jakarta EE 10.0.0 & 11.0.0-M4
- JDK 21.0.2
- Kotlin 2.0.0
- Mojarra 4.1.0
TIA.

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”:

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 32.0.0. 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();
}
}
