How does JSP save the last logon time of a user?

The Code is based on the access (favorite of a small website) library, for example, the date object uses java. SQL. date () type, Because java. util. date type is not allowed to be added to the DateTime type field: Author: tao

Import java. SQL .*;
Import java. text .*;
