I've been attempting to send objects from a Java Listener (not the JavaScript eventListener!) to a JavaScript application, but so far, I haven't had any success.
The specific requirement is that a JavaScript application running in the browser should request an object (such as an array) from a Listener upon launch, and the Listener should respond by providing the array. There are numerous ways to accomplish this task. What methods would be relatively secure and efficient?
Let's consider an example now. The JavaScript function can utilize jQuery to directly request the array from a JSON file (via HTTP GET request), and store its contents in a variable named 'data'. Here's how it can be done:
$.get("./myJSONfile.json", function( data ){
// Perform necessary operations
var myArray = data;
...
}
This can be achieved without involving any Servlet or Listener. How can I use a Listener to transfer the content of the JSON file to the JavaScript function?
