Answer 1

I faced the same problem (javax.ws.rs.NotFoundException: Could not find resource for full path ...). Based on this link, the steps to solve the issue are below:

1) Set the application class:

/**
 * Application class
 */
package com.abc.admin.services.config;

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

@ApplicationPath("/services") // the begining of the Webservice URL
public class WebConfig extends Application {
    private Set<Object> singletons = new HashSet<Object>();

    public WebConfig() {
        singletons.add(new UserResource());
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

2) Set the Resource class:

/**
 * Resource class
 */
package com.abc.admin.service;

import java.io.Serializable;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import com.abc.commons.ws.entity.UserWsPojo;

@Path("/user")
public class UserResource implements Serializable {

    private static final long serialVersionUID = 6766329501327292893L;

    @GET
    // there is a URL concatenation to access the method (.../services/user/getUser)
    @Path("/getUser") 
    @Produces(MediaType.APPLICATION_JSON)
    public UserWsPojo getUser(String id) {
        UserWsPojo uwp = new UserWsPojo();
        uwp.setName("Aayush");
        uwp.setSurname("Devmurari");
        return uwp;
    }
}

3) Set the web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>restContext</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
  <context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rest</param-value>
  </context-param>
  <servlet>
    <servlet-name>resteasy-servlet</servlet-name>
    <servlet-class>
        org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
    </servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.abc.admin.services.config.WebConfig</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>resteasy-servlet</servlet-name>
    <url-pattern>/rest/*</url-pattern> <!-- /* is not a comment, but part of the setting -->
  </servlet-mapping>
</web-app>

4) Test the configuration in a browser:

http://localhost:8080/restContext/rest/services/user/getUser
