I am using the version 1.17 of Jersey, Tomcat 8 over Eclipse Mars.2, JDK 7. It's a project that used to work fine one year ago, after import the project as a Maven project, configure the Java Build Path, clean it, update it, build it and deploy it in Tomcat when I try to access to the app to the index.jsp for example, I receive an error 404. Tomcat is working because I can see the main page and access to the status (where I see that my war is deployed)

I have the feeling that my Servlet is not working properly.

This is my web.xml

package pfc.virtualshopws.endpoint;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

// Plain old Java Object it does not extend as class or implements 
// an interface

// The class registers its methods for the HTTP GET request using the @GET annotation. 
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML. 

// The browser requests per default the HTML MIME type.

//Sets the path to base URL + /hello
@Path("/hello")
public class HelloEndPoint {

  // This method is called if HTML is request
  @GET
  @Produces(MediaType.TEXT_HTML)
  public String sayHtmlHello() {
    return "<html> " + "<title>" + "Hello Jersey" + "</title>"
        + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> ";
  }

}

I tried to access to http://localhost:8085/virtualShopWS/api/rest/ (it should show the welcome file index.jsp) or access to http://localhost:8085/virtualShopWS/api/rest/hello to see the "Hello Jersey" in both cases I received an 404 error.

Thank you in advance :)

  • Not sure, but try `@Path("api/rest/hello")` instead. Also, the `` only applies when no servlet mapping matches, so `.../api/rest/` will not automatically translate to `.../api/rest/index.jsp`. – Andreas Nov 29 '16 at 08:43
  • I tried both solutions but It's not working, I checked with a colleague from work He told me that probably It's because Tomcat it's not configured properly for running with Eclipse in my project – Danychi Nov 29 '16 at 13:10
  • Solved by myself, the problem was more stupid that what I thought, a few days ago the pom.xml was giving me this error "web.xml is missing and is set to true" I found this solution http://stackoverflow.com/questions/31835033/web-xml-is-missing-and-failonmissingwebxml-is-set-to-true but this solution created the webapp folder inside my folder resources, I just moved this folder outside with the folder "java" and "resources" now the pom.xml is finding propely the web.xml. – Danychi Nov 29 '16 at 19:16
