(object based) & I have to open and close the connection for every request.
Is there any way to re-use the http connection without closing the connection & Is it possible to maintain session
in this applet-servlet communication.
thanks in advance

The answer is: yes, you can mainiant the connection open. But I would not recommend this because mainianing an open connection for every client might need a many resources on yur server. I imagine that you want to keep the connection open so that the server could notify the client about some events. A simmillar behaviour can be obtained by periodically polling the server for new events.

thanks Mircea Crisan
I want to use persistent connection only because
the no. of Users of my application are less & number of
request's by each User are more, so how can I use a
persistent between applet & servlet, please help

URL url_base = getCodeBase();
String strHost = url_base.getHost();
String strPath = url_base.getPath();
int inPort = url_base.getPort();
URL ServletURL = new URL("http://"+strHost+":"+inPort+strPath+"servlet/ServletServer");
