Calling HTTPS webservice while JBoss act as a client

I would like to call webservice from my application which is deployed on JBoss eap.
My webservice enabled two way ssl, so JBoss will act as client and I have to config jboss server to send certificate to webservice.
Right now I have config certificate on http connector section which has keystore and truststore. and also import certificate of webservice to truststore and cacert file

But handshake_fail was always occur.
after I enabled debug ssl in jboss. It seems jboss does not pick any certificate to webservice.

Do I have to config anything else?
Any solution or idea would be appreciate.
