Metro webservices security on Eclipse

Hi,

I want to learn Metro webservices security using Eclipse and Tomcat 7. I have done this on Nebeans. But I face problem on Eclipse because I do not know where and how should I configure X509 certificates, UsernameToken etc. For ws-profile, I generate wsdl using Netbeans and copy it in Eclipse project. But I do not know where other security settings should be confgured.

Thanks
