Statement stmt=conn.createStatement();
String sql = "select * from users where username='" + username + "'";

ResultSet rs=stmt.executeQuery( sql );
if( rs.next() ){
session.setAttribute("login","ok"); //验证通过之后，跳转到后续页面
session.setAttribute("uname",username);

}else
out.println("错误的用户名和密码"); //验证未通过，显示错误信息
out.println("<a href=index.html>返回</a>");
}catch(Exception ee){
ee.printStackTrace();
}
}else{
out.println("请先登录！"); //验证未通过，显示错误信息
out.println("<a href=index.html>返回</a>");
}
%>
</body>
</html>

程序就运行到Class.forName("oracle.jdbc.driver.OracleDriver");

提示错误：java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

请问是什么原因

我在工程配置properties->Java Build Path->Libraries包含了classes.zip驱动包
