Servlet hangs out when web app. first loads

Question

I was trying to prepare a servlet which is loaded when the web application first starts on the server. It was loaded when I try the project but it hung out and the first page on the site had never shown; it seems like it is loading the the first page, but it isn't. What is wrong?

Answer 1

Sorry I am a new comer and confused about the situation. I think you mean applets can directly communicate
with servlets directly. I want to connect two applets each other through sockets and I want the servlet to
provide the connection each other. Is it possible?It sounds like you haven't grasped the way servlets work.
Webapps work through a series of transactions. The browser sends a request to the server which is typically a web URL, but may contain some form data. If the URL is directed to a servlet the server then invokes that servlet's doGet or doPost method which does some processing, sends a response back to the browser and then exits.
The servlet doesn't run continuously. It must either create a response of forward the request to another servlet or JSP and exit without undue delay.
If an applet wants to communicate with a webapp it sends an http request of it's own, which may well be handled by a servlet (probably not the one that created the applet page). It's a separate request.
On the server side separate requests are only connected through "session data". Your servlet can store some data in a Session object which can be retrieved by subsequent transactions from the same browser.
