Which version of WSAD do you use? In WSAD 5 it's possible to exchange soap messages over SSL. You have to contact the SSL Port (usually Port 9443) of the WSAD test server. A Java client will not connect to the test server because it hasn't been certificated and I don't know how to do this. Any help is appreciated. Regards, Stephan Lachenmaier
You can secure a SOAP message exchange by either securing the connection with SSL or the individual messages by applying WS-Security. A detailed explantion is not possible here. So I would rather point you to the freely downloadable sample chapter Web Services Security on J2EE Security for Servlets, EJBs and Web Services.
