Hi, I'm running a Web Service client on JBoss 4.0.5 and JBossWS1.0.4GA. The Web service I'm trying to consume requires mutual SSL authentication. I have created keytore, with the private key, the certificate in it. I also added the Web service provider's certificate to this keystore as a trusted certificate. I have configured my server.xml file to include the following: <Connector port="8443" address="${jboss.bind.address}" | maxThreads="100" strategy="ms" maxHttpHeaderSize="8192" | emptySessionPath="true" | scheme="https" secure="true" clientAuth="false" | keystoreFile="${jboss.server.home.dir}/conf/jboss.keystore" | keystoreType="jks" | keystorePass="password" sslProtocol = "TLS" /> But I guess this is not good enough (I don't feel that way either). So when I called the service, the error message said that my request did not present a certificate. How do I configure my Web service client, or write some code, to make sure that my web service request (to a https URL) will present a client certificate? I saw that you could specify user ID and password in the <service-ref> tag if you are using basic authentication. But I need certificate-based authentication and couldn't find an example. SOAP signing doesn't help me either because the Web service provider expects the certificate to be presented during the SSL handshake. Thanks!
