Problems using https protocol to connect to open a web site

Question

Hi,
I am trying to connect to a web site from my java programme. When I try connecting using htpp protocol, I am able to open the web page then I am giving the username,password to login into that web site..its working fine.
But, When I try connecting using https protocol connection, I am not getting the page opened and after some time I am getting below error
Exception in thread "main" org.apache.xmlrpc.XmlRpcException: I/O error while communicating with HTTP server: Connection timed out: connect
     at org.apache.xmlrpc.client.XmlRpcCommonsTransport.writeRequest(XmlRpcCommonsTransport.java:244)

     at com.wipro.bugc.Test1.main(Test1.java:124)
Caused by: java.net.ConnectException: Connection timed out: connect
Can anyone please suggest or give sample code to work with https web sites in java.
I will have to use only https protocol to open any browser as my server only opens the web pages using https protocol
Thanks in advance
