Question

I am writing a servlet, where I have to process the user data. But since processing the data takes time, I need to send response that user and data is valid, before I process the data. Is there a way I can first send the response, and then process the data. Something like,

response.send();
processData();

Thanks

Answer 1

Put the processData in a different thread. ex:

if(!processOn){
    processOn = true;
    new Thread(){
        public void run(){
            processData();
        }
    }.start();
}
response.send();

Where proccessOn is a session/static boolean that is used not to relaunch the process twice.
