Answer 1

For display tag there is not required any configuration in web.xml

display tag is used for pagination sorting in your grid data

there is put only more three jar (1)displaytag-1.2,(2)displaytag-export-poi-1.2,(3)displaytag-portlet-1.2

and write tag lib in your jsp page like:

   <%@ taglib uri="http://displaytag.sf.net" prefix="display"%>    

your code for griding:

        <display:table name="sessionScope.yourListname" pagesize="5" sort="list" cellspacing="10" cellpadding="5">

            <display:column property="var1" title="Title1" sortable="true" />  
            <display:column property="var2" title="Title2" sortable="true" />  
            <display:column property="var3" title="Title3" sortable="true"  />  

        </display:table>
