how to create a keystore

Hello,

I have received a public key from a client. I want to test one webservice (HTTPS) call through SOAPUI.
I created one empty keystore using the keytool IUI and I have then imported the clients pubilc key in that keystore(using same keutool IUI).

Now I am configuring the keystore I generated in my SOAPUI (version 3.0.1) ssl settings.
But while configuring the key store details, I am getting below error.

"Thu May 13 02:16:15 PDT 2010:ERROR:An error occured [Can't build keystore: [No certificates belong to the private-key]], see error log for details
"

Can any one please help me resolving this issue.
Do I need to configure client private key also in my keystore. Or am I doing anything wrong during keystore
generation process?

Please suggest.
