Clarification needed on SSL protocol

[Vasudevan Comandur]

Hi,

    I am using HTMLUnit stack to connect to some websites. It was an HTTPS
    session. Some times the SSL handshake goes through successfully but many
    times the SSL handshake fails.

     When I looked into the wireshark trace, what I found is the following:

    Client - Client Hello on SSLv2 protocol with the list of cipher suites
sent.

    Server - Alert code 0 on TLSV1 protocol

     Client - Alert Code 10 on TLSV1 protocol

      The app gets SSL peer not authenticated exception.

     Is there any reason why it fails?. But I did not see this behaviour
with the real
      browser (FF)?. How this can be fixed from the client side?

      THanks in advance for the reply.

Regards
 Vasu
