use maven spring and jersey in an web rest service project? - spring

Question

I have a Java application and it uses maven, jersey, spring and other libraries for that.
I use this tutorial github.com/erkobridee/restful-bookmarks-jerseyspring/tree/master/src/main
as guide for my project.
pom.xml is as follows:

I can't post an image from my project structure. My index.html is in src/main/webapp/index.html
When i call the url http://localhost/decon-fm-5/index.html in my browser, than called an 404 status error.
Why? What is the problem?
I can call my ApplicationController action in my browser with url http://localhost/deconFM_V5/app/login
package de.decon.v5.core.controller;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("/app")
public class ApplicationController
{
#GET
#Path("/login")
#Produces(MediaType.APPLICATION_JSON)
public String application()
{
String loginForm = "{\"form\" : {\"name\" : \"login\"}}";
return loginForm;
}
}
Thank much for yours help

Answer 1

you are mapping all reqeust to jersy spring servlet it will look for a mapping for index.html in your Rest Endpoint if not found it will give 404. Ideally you should map /api/** or something for your Rest Endpoint .
Eg:
http://localhost/decon-fm-5/api/v1/resourcename/id
make the following change
<servlet-mapping>
<servlet-name>decon-fm-5</servlet-name>
<url-pattern>/api</url-pattern>
</servlet-mapping>
