Write an class extending Struts'
Actionclass. This class pulls the data from Database as aList. Pass this data as request attribute,request.setAttribute("myList", list). Return "success".In your
struts-config.xml, map thisActionclass to a JSP on "success". The request will be forwarded to the JSP.In the JSP, get the list from request by
request.getAttribute("myList"). Iterate through the list and print theList.
You need to study this: http://struts.apache.org/1.x/userGuide/index.html

I am using a HashMap to store the data from a row . Then i am adding this HashMap to an ArrayList . How to iterate the ArrayList Of HashMaps in my jsp page using <logic:iterate > ??
(Edit: Just noticed this is a 2 year old question)
Don't use the struts tags unless you NEED to. This can be accomplished with jstl/el. So on your Action class you would have something like this:
List<Map<?, ?>> listOfHashMaps = new ArrayList<Map<?, ?>>();
request.setAttribute("listOfHashMaps", listOfHashMaps);
In your jsp:
<c:forEach var="hashMap" items="listOfHashMaps">
${hashMap[someInteger]} <%-- To get the value associated with 'key' --%>
</c:forEach>
You can also access the keys/values with:
${hashMap.key}
${hashMap.value}
Respectively.
