I have just bootstrap an Intellij JAX-RS project, but when trying to run I got an 404 to the "/api/hello-world" provided by the boilerplate code.
The HelloServlet works correctly on Tomcat 10, so I thing it may be something in the configs that Intellij may have not got me covered and I have no clues on how to fix it!
I tried to add the servlet section to web.xml (at the end of code blocks), but IDE complaints: "'com.example.demo.HelloApplication' is not assignable to 'javax.servlet.Servlet,jakarta.servlet.Servlet'"
I got curious because I am not using "javax" but "jakarta":
Application:
package com.example.demo;
import jakarta.ws.rs.ApplicationPath;
import jakarta.ws.rs.core.Application;
@ApplicationPath("/api")
public class HelloApplication extends Application {}
Resource:
package com.example.demo;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
@Path("/hello-world")
public class HelloResource {
@GET
@Produces("text/plain")
public String hello() {
return "Hello, World!";
}
}
Servlet (Working)
package com.example.demo;
import java.io.*;
import jakarta.servlet.http.*;
import jakarta.servlet.annotation.*;
@WebServlet(name = "helloServlet", value = "/hello-servlet")
public class HelloServlet extends HttpServlet {
private String message;
public void init() {
message = "Hello World!";
}
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
response.setContentType("text/html");
// Hello
PrintWriter out = response.getWriter();
out.println("<html><body>");
out.println("<h1>" + message + "</h1>");
out.println("</body></html>");
}
public void destroy() {
}
}

I tried the same project in javax (Tomcat 9) but the same happened, so no where to go from here.
