Get Exchange server certificate file   

Hi,Sir

Since one of my customer exchange setting is SSL Enabled.
I am a Java Client, So If I want to get public folder content throught http
I have to use https, and on Java client side,It will import the certificate
when user want to use https.

So , On exchange server side, I open IIS manager, and right click on the node 
Default site to create certificate.however,it only create a temp text file.
and tell me to send that file to CA Authroite to create *.pfx or *.ssl file.

I am not sure, it is my step wrong, or what should I do?
how to get certificate file from exchange server to access public folder 
throught HTTPS

Thanks
