Using Display tag library - sorting and Paging

Question

I have generated a grid using this tag library which has number of in built features. Out of which on is grid sorting and pagination. But this sorts the grid in one page only, not complete grid. Does any one have solution for this? I am trying to get the source code which does this. If any one has solution then please help me..
Thanks!

In this case you have to do external sorting insted of defalutsorting provided by dispaly Tag Library. find sample code for External Sorting.
Follow the Steps:
<display:table name="testList" {color:#ff0000}sort="external"{color} defaultsort="1" id="empTable">
<display:column property="id" title="ID" sortable="true" {color:#ff0000}sortName="id"{color} />
<display:column property="firstName" sortable="true" title="First Name" />
<display:column property="lastName" sortable="true" title="Last Name" />
<display:column property="address" sortable="true" title="Email Address"/>
</display:table>
To determine the request parameter name for column(like ID) sorting you can do :
String studenid = request.getParameter((new ParamEncoder("empTable")).encodeParameterName(TableTagParameters.PARAMETER_SORT))
fire a query in DAO Class using request parameter to get sorted list and map a resultset to table.
