Error 404 - the requested resource is not available

Question

I'm very new to Java, I'm attempting to create a very simple Rest API to return a string via a GET method. I've been through countless tutorials, but each time I get the above error using my project

url - http://localhost:8080/orchestrator/api/service/status

I'm using the ApplicationConfig.java - ApplicationPath file to denote the mapping:

@javax.ws.rs.ApplicationPath("/api")
public class ApplicationConfig extends Application {

@Override
public Set<Class<?>> getClasses() {
    Set<Class<?>> resources = new java.util.HashSet<>();
    addRestResourceClasses(resources);
    return resources;
}

/**
 * Do not modify addRestResourceClasses() method.
 * It is automatically populated with
 * all resources defined in the project.
 * If required, comment out calling this method in getClasses().
 */
private void addRestResourceClasses(Set<Class<?>> resources) {
    resources.add(com.orchestrator.Services.class);
} }

Using Netbeans 12.6 with Tomcat via XAMPP v3.3.0; I have a web.xml but apparently I don't need it as I'm using the ApplicationConfig.java, but I'll post the one I made.

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>.com.sun.jerysey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>com.orchestrator.Services</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

Services.java

@Path("/service")
public class Services {

@Context
private UriInfo context;

public Services() {
}

@Path("/status")
@GET
@Produces(MediaType.TEXT_PLAIN)
public String getHtml() {
    //TODO return proper representation object
    return "connected";
}
}

Project Structure: image of folder structure

What am I missing to return the "connected" text, I've also tried using postman as well to return, same result.

Regards

the web.xml is the second code block in the main post. Further exploring has shown that my project is deploying to tomcat -> work -> Catalina -> localhost. Shouldn't this be in webapps? — Locksley, Jan 06 '22 at 18:57

Looks like you're calling a wrong route.

Your applicationPath begins /api and not /orchestrator/api

You can try with this route http://localhost:8080/api/service/status

Unfortunately, this doesn't work using http://localhost:8080/api/service/status - browser returns - Message The requested resource [/api/service/status] is not available; The origin server did not find a current representation for the target resource or is not willing to disclose that one exists. – Locksley Jan 06 '22 at 06:07
What was returned when you try to reach http://localhost:8080 – Hassan Liasu Jan 06 '22 at 06:42
It returns the Tomcat main page; XAMPP also confirms it's running Tomcat on 8005, 8080 – Locksley Jan 06 '22 at 06:49
