Import Certificates for Web Services Protected by SSL
If you make calls to web services that are protected through Secure Sockets Layer (SSL), then you must export the certificate from the web server hosting the web service and import it into the Java keystore on the computer that's running Publisher.
These steps shouldn't be required if the server certificate is linked to some certificate authority (such as Verisign). But if the Web service server is using a self-generated certificate (for example, in a testing environment), then these steps are required.
