Programming struts tags usage

struts tags usage
using arraylist and maps
define in your action

List  urlName = new ArrayList();

for (Iterator i = st.iterator();  i.hasNext();) {

String str = (String)i.next();

uniqueSet.add(str.substring(0, str.indexOf(".")));

String  kstr = str.substring(0, str.indexOf("."));

Map surlName = new  HashMap();

surlName.put("url", sysUrlMap.get(kstr));

surlName.put("name", sysNameMap.get(kstr));

urlName.add(surlName);

}

session.setAttribute("uniqueSysSet", uniqueSet);

session.setAttribute("urlNameList", urlName);

in your jsp retrieve the object and use logic iterate to loop over list containing maps

<%

List urlName = (List)  session.getAttribute("urlNameList");

pageContext.setAttribute("listurlname", urlName);

%>

<logic:iterate id="urlnamelist"  name="listurlname">

<td><a href='<bean:write  name="urlnamelist" property="url" />' target="leftFrame"><bean:write  name="urlnamelist" property="name" /></a></td>

</logic:iterate>
