Could not find resource for path in JAX-RS with RESTEasy

Question

I created a maven project with archetype as maven-archetype-webapp, and then for exposing my application as a rest webservice i'm using RestEasy, however after implementin the rest application i'm unable to acces the URL created by me. Please guide me in what i'm doing incorrectly. Thanks for reading the question.

My UserManagementController is as below :

package com.restimplement.btl.pl.controller;

import javax.ws.rs.DefaultValue;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Response;

import com.restimplement.btl.pl.dao.UserDao;

@Path(value="/UserManagement")
public class UserManagementController {

    @GET
    @Path("/{pathParameter}")
    public Response getAllUsers( @PathParam("pathParameter") String pathParameter,
            @DefaultValue("Nothing to say") @QueryParam("queryParameter") String queryParameter)
    {
        UserDao userdao = new UserDao();
        System.out.println("able to visit  user add");
        String response = "details from: "+userdao.findObject();
        return Response.status(200).entity(response).build();
    }

}

My MyRestWS.java is as below :

package com.restimplement.btl.pl.controller;

import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.core.Application;

public class MyRestWS extends Application{

    private Set

The `web.xml` is not required in servlet 3.x environments

In a Servlet 3.x environment (like WildFly 8.x), the web.xml deployment descriptor is not mandatory and you may not need it in a simple application.

You could remove it and configure your maven-war-plugin to ignore the missing web.xml file by setting failOnMissingWebXml configuration property to false in your pom.xml file:


    ...
    
        org.apache.maven.plugins
        maven-war-plugin
        3.0.0
        
            false
        
    
    ...

Fixing your `Application` subclass

Change your Application subclass to be like:

@ApplicationPath("btlservice")
public class MyRestWS extends Application {

    @Override
    public Set> getClasses() {
        HashSet> set = new HashSet>();
        set.add(UserManagementController.class);
        return set;
    }
}

The getClasses() method returns a set of root resource, provider and feature classes. The default life-cycle for resource class instances is per-request. The default life-cycle for providers (registered directly or via a feature) is singleton.

The @ApplicationPath annotation can be used to annotate the custom Application subclass and define the base application URI for all JAX-RS resources configured in the application. With it you don't need to declare a servlet in the web.xml deployment descriptor.

For more details on the Application class, this answer can be insightful.

Requesting your endpoint

Finnally, request your endpoint that should be available in the following URL:

http://[server]:[port]/[context]/btlservice/UserManagement/[path-parameter]
