The pre provided answers did not help me in my case when I try to run my server in eclipse and it gives me a class not found exception

Question

This is my web.xml file:

<?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"
version="3.1">
<display-name>Book Service</display-name>
<servlet>
<servlet-name>book_service</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>bookservice</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>book_service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>

This is my class file:

package bookservice;

import java.util.ArrayList;
import java.util.List;

public class Books {
    private static ArrayList<Book> books = new ArrayList<>();
    static {
        books.add(new Book(1, "The Outliers", 500));
        books.add(new Book(2, "World Is Flat", 550));
    }
    public static List<Book> getBooks() {
        return books;
    }
}

I used these jar files included in the image: 1

When I run my server I'm getting a 404 - Not Found error. Also there is an class not found exception in the console.

I copied all jar files to WEB-INF/lib. I switched location in server properties and double clicked on server and change server locations to "Use tomcat installation". I changed the web.xml according to the following link's solution

2 But any of these solutions didn't help me. How to handle this issue

Hint: just "trying" solutions is probably not going to work. You need to 1) **understand** the cause(s) of problem, then 2) **diagnose** your particular instance of the problem to figure out which of the possible causes applies to you. Then **and only then** should you try to apply a relevant solution. — Stephen C, Apr 29 '18 at 05:09
Hint 2: Telling us *"I tried all of the solutions and they don't work"* won't help us. It doesn't tell us which solutions you tried, whether they were applicable, whether you applied them **properly** and ... whether they made any difference. It also doesn't help us find out what the real problem is. — Stephen C, Apr 29 '18 at 05:12
Hint 3: The evidence suggests that your actual problem is precisely this one: https://stackoverflow.com/a/22023981/139985. Read it carefully, and compare it with what you are doing. — Stephen C, Apr 29 '18 at 05:16
