(1) Is there any place that I can get a documentation with the necessary steps to do this? Maybe a book or a tutorial? I have got some information about individual steps in the internet, but I dont know how to put all the parts together!? (2) When you say that I should use Tomcat, are you suggesting that I should transform my JApplet in Servelet? Or I can also use the Tomcat for dealing with JApplets?
"If you really want to send the output of your applet to the webserver which originally served the applet to the client's browser, you can make a POST request using HttpUrlConnection to your webserver and send the data as the payload of that request. Note that there has to be something running on the webserver that can handle the request with the student's data in it. Whatever it is that responds to that request will have to be written by you in Java (Tomcat is a popular Servlet container) or another language like PHP. That code must understand the content of the request from your Applet and do something meaningful with it - probably save it in a database."
I hope that I am not bothering you with dummy questions, but it seems that I am a kind of lost. Thank you again!
