I don't think this subject is really on topic for the tomcat list...
import javax.net.ssl.*;
import java.net.*;
public class HTTPTest
{
public static void main (String args[])
{
try
{
URLConnection myConnection =
(new URL("https://somesite.somedomain.com/";)).openConnection ();
System.out.println (myConnection.getInputStream().available());
}
catch (Exception exception)
{
System.out.println (exception.getMessage());
}
}
}
Try the following guys, and tell us what happens.
Maybe you might want to email me direct since this is a tomcat list, not a
java list.
