AngularJS AJAX call to a servlet in JAVA

Question

My class in the project is under a package com.project.controller and the name of the servlet class is UpdateDatabaseController. The corresponding code of the web.xml is,

<servlet>
    <servlet-name>UpdateDatabaseController</servlet-name>
    <servlet-class>com.project.controller.UpdateDatabaseController</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>UpdateDatabaseController</servlet-name>
    <url-pattern>/UpdateDB</url-pattern>
  </servlet-mapping>

In the html page, I have a button that is calling a function, updateDatabase(). And the code of the script is:

$scope.updateDatabase = function(){
        $http.get('/UpdateDB').success(function(data) {
            alert("Controller hit");
        });
    };

Whenever I hit the button, the error in the browser log is displayed, that : "NetworkError: 404 Not Found - http://localhost:8080/UpdateDB"

I want that on my button click, the POST method of the servlet class is invoked. But the error is fixed in the browser log. I am unable to solve this situation.

you miss ProjectName in ur URL localhost:8080/ProjectName/UpdateDB — Ahmed Adel

I got it correct. But suppose I want to call a particular method in the servlet, shall I append the name of the method behind the URL? — Prateek

$scope.updateDatabase = function(){
        $http.get('http://localhost/YourProject/UpdateDB').success(function(data) {
            alert("Controller hit");
        });
    };

I had the same problem, and fixed it by adding http:// in front of the link.
