#38589 — Examples of SSL/TLS implementation

Hi,

I am looking for good examples of SSL/TLS implementation in Java.  I
can find plenty using HTTPS, but this is a propratory protocol.  I
just need to connect to a TLS server socket and check certificates
etc.  Then just send and receive data.

More specifically I am confused about how to use SSLSocketFactory.
When should the getDefault() method be used and when to use the
createSocket() methods.

http://www.vajhoej.dk/arne/articles/socket2.html#sslcli
http://www.vajhoej.dk/arne/articles/socket4.html#sslcli

have an example (the SSL part is the same for the two).

Thanks.  How can I change this to only accept the particular
(specified) certificates?

The checkServerTrusted has access to the certificate and
can throw a CertificateException if it does not like what it sees.
