AngularJS and Java Servlet does not work
Question
I found a piece of code to use AngularJS with Java Servlet.
The problem is that when I run the application it tell me that the 'AtpPlayers' page it does not exists and, of course, it does not fill my table.
I was trying in JBOSS server and json-simple-1.1.1.jar library.
What is doing wrong?
The servlet is here:
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/AtpPlayers")
public class AtpPlayers extends HttpServlet {
private static final long serialVersionUID = 1L;
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("application/json;charset=UTF-8");
try {
PrintWriter out = response.getWriter();
out.println("[{\"name\": \"Nadal, Rafael (ESP)\", \"email\": \"nadalrafael@gmail.com\", \"rank\": \"1\"},"
+ "{\"name\": \"Djokovic, Novak (SRB)\", \"email\": \"djokovicnovak@gmail.com\", \"rank\": \"2\"},"
+ "{\"name\": \"Federer, Roger (SUI)\", \"email\": \"federerroger@gmail.com\", \"rank\": \"3\"},"
+ "{\"name\": \"Wawrinka, Stan (SUI)\", \"email\": \"wawrinkastan@gmail.com\", \"rank\": \"4\"},"
+ "{\"name\": \"Ferrer, David (ESP)\", \"email\": \"ferrerdavid@gmail.com\", \"rank\": \"5\"}]");
} catch (Exception e) {
System.out.println(e);
}
}
}
The HTML & JS code is that:
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.8/angular.min.js"></script>
</head>
<body ng-app="ATP_PLAYERS">
<div ng-controller="atpController">
<h5>Loading ATP players from a Servlet</h5>
<table>
<thead>
<tr>
<th>Rank</th>
<th>Name</th>
<th>E-mail</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in atp">
<td>{{item.rank}}</td>
<td>{{item.name}}</td>
<td>{{item.email}}</td>
</tr>
</tbody>
</table>
</div>
<script language="javascript" type="text/javascript">
angular.module('ATP_PLAYERS', [])
.controller('atpController', function ($scope, $http) {
$http.get('http://localhost:8080/AngularGET/AtpPlayers').then(function (data, status, headers, config) {
$scope.atp = data;
alert('OK');
}, function (data, status, headers, config) {
alert('NU');
});
});
</script>
</body>
</html>

I found the problem:
$http.get('http://localhost:8080/AngularGET/AtpPlayers').then(function (data, status, headers, config) {
$scope.atp = data;
alert('OK');
}, function (data, status, headers, config) {
alert('NU');
});
replaced with:
$http.get('http://localhost:8080/AngularGET/AtpPlayers').then(function (response) {
$scope.atp = response.data;
alert('OK');
}, function (response) {
alert('NU');
});
I don't knows why the guy which write the original code was typed "function (data, status, headers, config)"...
