WSDL authentication in NWDS 7.0.14

Hi SDN,

In Webdynpro, I am consuming WSDL generated in XI System. During consumption in the webdynpro, I need to mention the XI userid and password i.e., authenticate the XI system to consume and execute the WSDL.

request._setUser(XIUsername);

request._setPassword(XIPassword);

This methods are available only in NWDS 7.0.0 and not in higher versions say 7.0.14. How to set authentication in higher versions. If anybody have done it..please share...

Thanks & Regards,
