How can we return a JSON object from a Java Servlet

Question

Is there any way to return a JSON object from a Java Servlet?

Answer 1

response.setContentType("application/json");
// Get the printwriter object from response to write the required json object to the output stream      
PrintWriter out = response.getWriter();
// Assuming your json object is **jsonObject**, perform the following, it will return your json object  
out.print(jsonObject);
out.flush();
