Duan,
Thanks for the help.
Below is the stack trace of the java client i use:

I got this while i tried to connect with the sample servlet that comes with
tomcat. Is that enough?
Below is the snippet of the code i use:
URL url = new
URL("https://<myserver>:8443/servlets-examples/servlet/HelloWorldExample");
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn
.getOutputStream());
Where am i doing wrong? I guess the problem is with client(as you pointed
already) but unable to figure out the exact problem. The client and server
both are in the same system.
regds,
