SSL Client does not return certificate

[Joe Wong]

Hello,

I use keytool to import the client certificate into a keystore file. In
the program, I used

System.setProperty("javax.net.ssl.keyStore", "myclient.ks");
System.setProperty("javax.net.ssl.keyStorePassword", "password");

To specify the client server.

When connecting to my test SSL server, which is implemented in Python,
It reports the error:

SSL3_GET_CLIENT_CERTIFICATE, 'peer did not return a cerficiate'

How can I program my client to send the correct certifcate to the server?

Best regards,

- Joe
