Is is like this? :
<TD><%= arrayList.get(n) %></TD>

 

[Deepa]

I have added in arrayList like this

retArrayList.add(rs.getString(5));
log.debug("First name of terminated emp : " +
rs.getString(5));
retArrayList.add(rs.getString(6));
log.debug("Last name of terminated emp : " +
rs.getString(6));

say if there are 7 records then arrayList returning its size as 14 (7
for firstname and 7 for lastname). but according to me its size shod be
7.

This code is in Struts how to collect listobjects from actionclass,helper,DAo and get that list in jsp using struts tags
objuserDatalist = objLoginHelper.getUserDataList();
request.setAttribute(USER_DATALIST, objuserDatalist);

-<---objUserDataList = objLoginDAO.getUserDataList();<---objEmpList = (ArrayList) session.createQuery("from EmployPOJO where empStatus='A'").list();
---------------------------------------------------------------------------
request.setAttribute(USER_DATALIST, objuserDatalist);

<logic:notEmpty name="userDataList">
<logic:iterate name="userDataList" id="userlist">
<td> <bean:write name="userlist" property="empId"/></td>
<td> <bean:write name="userlist" property="empName"/></td>
<td> <bean:write name="userlist" property="empDesg"/></td>
<td> <bean:write name="userlist" property="empComp"/></td>
<td> <bean:write name="userlist" property="empLoc"/></td>
<td> <bean:write name="userlist" property="empMob"/></td>
<td> <bean:write name="userlist" property="empPhone"/></td>
<td> <bean:write name="userlist" property="empMail"/></td>


</tr>
</logic:iterate>

from jdbc or hibernate return List (with db data either using jdbc or hibernate)and set that list into request is best practice (or session ) like request.setAttribute("objList", objuserDatalist); and get list in jsp by using JSTL or EL expressions(like $list)

1. <C:IF test="${not empty names}">
2. <C:FOREACH var="objList" items="${objList}">

1. <C:OUT value="${objList.name}"></C:OUT>
2. <C:OUT value="${objList.id}"></C:OUT>
3. </C:FOREACH></C:IF>
