Security Certification while testing request/response

Hi,

I am trying to configure the security parameters to access the secure webservices via SoapUI. Having said that, all the steps that are mentioned http://www.soapui.org/soapui-projects/ws-security.html are being followed but still I'm unable to access the secure facade. Just wanted to know if I'm missing something here? or do we have any alternative to resolve the issue?
