RESTEasy 404 not found

i'm trying to create an API using RESTEasy, i've been looking for hours on differents topics but none could resolve my issues.

I spent one hour trying different url's, none worked, the project used to work when i was using jersey but the fact is that i'm on wildfly 10 so it's a bit complicated to deal without runtime (or maybe not but i already lost so much time configuring everything that i'm exhausted with such steps).

Here is my WEB.XML

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
    <display-name>api</display-name>
    <servlet>
        <description>JAX-RS Tools Generated - Do not modify</description>
        <servlet-name>RestEasy</servlet-name>
        <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
        <init-param>
            <param-name>api</param-name>
            <param-value>api</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>RestEasy</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

Here is my Application class

@ApplicationPath("/api")
public class JaxRSActivator extends Application {

    public JaxRSActivator() {
        // TODO Auto-generated constructor stub
        System.out.println("Je passe dans le constructeur de l'application");
    }

}

Here is an exposed service :

package api;

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import entities.ApiUser;

@Path("ApiUser")

    public class ApiUserAPI {

        @POST
        @Consumes(MediaType.APPLICATION_JSON)
        @Produces(MediaType.APPLICATION_JSON)
        public Response createUser(ApiUser user) {
            System.out.println("JE PASSE DANS LE POST");
            if (user.getUsername() == null && user.getPwd() == null)
                return Response.status(404).build();
            return Response.status(200).build();
        }

        @GET
        @Produces(MediaType.APPLICATION_JSON)
        public Response findUser() {
            System.out.println("JE PASSE DANS LE GET");
            return Response.status(200).build();
        }

    }

Here is the pom

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>3.0.2.Final</version>
    <scope>provided</scope>
</dependency>

<!-- https://mvnrepository.com/artifact/org.jboss.resteasy/resteasy-jackson-provider -->
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson-provider</artifactId>
    <version>3.0.19.Final</version>
</dependency>

I've been working 3 hours on this and i'm not even able to catch a GET. As far as i can remember on all topics i've been through, there were almost 10 differents possibles URL to send this request. I think i tried them all.

Could someone tell me what's wrong in it and eventually the url i should use to send this damn GET request ?

ThanksFully yours,

There are a few things you must pay attention to:

  1. In a container that implements the Servelt API 3.x, such as WildFly 10, you don't need the web.xml deployment descriptor when deploying a simple web application. In your situation, you can safely remove it. Keep the things simple to start.

  2. In your pom.xml, ensure you have the same version of all RESTEasy artifacts.

  3. Register the ApiUserAPI class in your JaxRSActivator class by using the following lines:

@Override
public Set<Class<?>> getClasses() {
    Set<Class<?>> classes = new HashSet<Class<?>>();
    classes.add(ApiUserAPI.class);
    return classes;
}
  1. The URL should be http://[host]:[port]/[context]/api/ApiUser.
