The client jar contains two classes AxisClient and SSLAxisClient. As the current SOAP interface can only be accessed through ssl the SSLAxisClient should be used. To configure the client edit the .properties file in the jar (e.g. to set up a http proxy).
To establish a connection to the service just create a instance of the SSLAxisClient by calling SSLAxisClient client = SSLAxisClient.getInstance();. All commands can then be called on this client.
