I got a solution for my question.
we can use Implicit Objects of the Unified Expression Language .

I used in JSTL.

<c:forEach var="lhsSrcMap" varStatus="status" items="${lhsListMap}">  
   <c:set var="tileLhsSrcMap" value="lhsSrcMap" scope="request"/>
   <tiles:insert page="/jsp/common/lhsListing.jsp" >  

   </tiles:insert>
</c:forEach>  

<c:forEach var="fieldRec" varStatus="status" items="${tileLhsSrcMap.value['LIST']['SRC_DTL_MAPS_LIST']['FIELD_LIST']}" > 

//something  

</c:forEach>

or use

<c:forEach var="fieldRec" varStatus="status" items="${requestScope.tileLhsSrcMap.value['LIST']['SRC_DTL_MAPS_LIST']['FIELD_LIST']}" > 

//something  

</c:forEach>
