<%Iterator itr;%>
<% List data=(List)request.getAttribute("data");%>
I use servlet as my engine to proceed my sql statement.

select * from a natural left join b natural left join c natural left join d where dept='Marketing'
and then i use
List dataList = new ArrayList();
and add data from database into my datalist.
