SSL Socket error - java.net.SocketException: Socket closed

[shan]

My Java client program connects to a server (running IPlanet) and
performs login/logout every 5 minutes. When the webserver is restarted
I get the following exception.
The program uses SSL and com.sun.ssl.* is the SSL provider.
IS there anything I should do to re-initialize the sockets/etc.
When the client program is stopped and started again everything is
fine...

The following is the code segment where the exception is occuring....

run()
{
while (serverUp)
{
.....
....
try{
HttpsURLConnection vbg =
(HttpsURLConnection)url.openConnection();
vbg.setDoInput(true);
vbg.setDoOutput(true);
vbg.setUseCaches(false);
vbg.setAllowUserInteraction(false);
vbg.setFollowRedirects(false);
vbg.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
// exception occurs in vbg.getOutputStream()
DataOutputStream post = new
DataOutputStream(vbg.getOutputStream());

....
....
sleep(5*60*1000); // 5 minutes in milliseconds
}
catch (exception e)
{
e.printStackTrce();
}
}
}

Any help is very much appreciated.

This is quite normal (even without SSL).
There's no way for handling that, except reestablishing (reopening) the connection
in the catch block. The problem ist to hold the State of the client (reauthorization,etc.).

About Socket - recycling I can't tell you something. For clients,
that doesn't make some sense, I suppose.
