Regd Last Logon of User Logged onto portal

Hi Experts,

I am new to Enterprise Portal developments. I have a requirement like to display the last logon date and time of a person logged onto the portal.

The Last Logon date and time ought to be displayed in the portal masthead. I already tried a few methods in doing it but it was not successful.

In my coding I used getUserFactory() method to get the user data, but the compiler is throwing a compiling exception. I have included the com.sap.security.api.jar file. (Development is done in NWDS)

Still its showing error. Is there anything I am missing in the above method. Is there any easier method than the above ??

Thanks in Advance. Your help will be highly appreciated!!

Regards
