<s:property value="currentPageHotelList[#stat.index].room0"/> //this works ,
i want room0 make dynamic ( like room0 to room4)
<s:iterator begin="0" end="5" >
<s:set var="roomindex" value="'room'+top"></s:set> //this gives room0
,room1 ,room2 etc...
<s:property value="currentPageHotelList[#stat.index].%{#roomindex}"/> //

so currentPageHotelList[#stat.index] gives a Map?
if ur using an iterator u can just do
<s:iterator value="list" var="map"> <-- of course u can use "top" as well
but l like giving it a name
<s:property value="map[#roomindex]"/>
</s:iterator>

try:
invoke the [get] method on map:
<s:property value="currentPageHotelList[#stat.index].get(#roomindex)"/>
or
reference property on map:
<s:property value="currentPageHotelList[#stat.index].(#roomindex)"/>
or
iterator on values of map:
<s:iterator value="currentPageHotelList[#stat.index].values" var="item">
<s:property value="#item"/>
</s:iterator>
or
iterator on keys of map:
<s:iterator value="currentPageHotelList[#stat.index].keys" var="itemKey">
<s:property value="currentPageHotelList[#stat.index].get(#itemKey)"/>
</s:iterator>
