I have a form in HTML where I collect user input and store it as an object in JavaScript. Here is how I am creating the object:
var dataObject = {
Name: getName(),
Age : getAge()
}
Now, I want to send this object using Ajax to a backend Java Class (not a servlet). Here's my attempt:
$.ajax({
url: 'ServerResource',
type: 'POST',
dataType :'json',
data: dataObject,
success: function(response) {
alert('Data sent successfully!');
},
error: function(){
alert('Error occurred while sending data');
}});
However, when I try to run this code, I encounter a 404 Error stating 'Resource not found'. Any insights on why this issue might be arising? My goal is to pass data from client-side JavaScript to server-side Java for further processing. Also, please note that I am testing this on Internet Explorer (IE).
Additional Info:
Here is a snippet of my ServerResource.java:
public class ServerResource extends HttpServlet {
private static final long serialVersionUID = 1L;
public ServerResource(String dataObject) {
// TODO Auto-generated constructor stub
System.out.println(dataObject);
System.out.println("Inside Server Resource!");
}
}
