Tomcat error messages for JavaEE REST API

Question

I am trying to build a REST API using JavaEE and Apache Tomcat. I have some instructions on how to retrieve endpoint's message but it doesn't seem to be working for a reason I don't understand.

Java HelloWorld.java:

@Path("HelloWorldService")
public class HelloWorld {
    @GET
    @Path("/HelloWorld/{name}")
    @Produces(MediaType.TEXT_PLAIN)
    public String sayHelloWorld(@PathParam("name") String name) {
        return "Hello world from" + name;
    }

}

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <display-name>SCRM</display-name>
    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

When I build an open Tomcat to browser the URL has .war exploded artifact. But I am trying to hit the endpoint as follows:

http://localhost:8080/SCRM/rest/HelloWorldService/HelloWorld/mike

Errors:

Expected value:

Hello world from mike!

Is there any idea on what is going on?

Tools that I am using:

• Intellij IDEA Ultimate
• Java 11
• Jersey 1.19.4 .jars
• Apache Tomcat 9.0.581
