Hi,
DTO's.. its nothing much.. just create a POJO's with what ever attribuetes
you want to have.
for eg:
class Block {
private String blockNo;
private String location;
// public setter and getter method.
}
In you action class.. you populate each of these objects for the each row
you get from the DB. and add this bean to a list, so you get a list of
objects you want to display in page.., then add this list to the request and
in the jsp just iterate and display
eg:
<logic:iterate id="block" name="blocks" type="com.mycomapny.dpo.Block">
<bean:write name="block" property="blockNo"/>
</logic:iterate>
Thanks & Regards,
Nuwan

Hi,
The loop is wrong, your are overwriteing the same form bean, and also
what
i
would suggest is create a DTO for this and populate the DTO and add
create
a
list of those DTO's, and set it to the from or request from there you can
get the list and can easily iterate this list

Nuwan.

please help me in finding worng..
Action Class
-----------------------------------------------------------------------------
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception
{
DynaValidatorForm block = null;
try // try start
{
ds = getDataSource(request);
conn = ds.getConnection();
stmt = conn.createStatement();
String query = "SELECT UNIQUE B.BLOCKID AS BLOCKID, B.SHORTDESCRIPTION
AS
BLOCKSHORTDESCRIPTION, B.DESCRIPTION AS DESCRIPTION, B.ADDRESS AS
LOCATION,
B.PHONE AS PHONENO, B.COLLEGEID AS COLLEGEID, C.SHORTDESCRIPTION AS
COLLEGESHORTDESCRIPTION FROM BLOCKS B, COLLEGES C ORDER BY
B.SHORTDESCRIPTION";
rs = stmt.executeQuery(query);
blocks = new ArrayList();
if(rs.next())
{
do
{
block = (DynaValidatorForm)form;
block.set("id",rs.getString("BLOCKID"));
block.set("shortDesc",rs.getString("BLOCKSHORTDESCRIPTION"));
block.set("desc",rs.getString("DESCRIPTION"));
block.set("location",rs.getString("LOCATION"));
block.set("phoneNo",rs.getString("PHONENO"));
block.set("collegeShortDesc",rs.getString("COLLEGESHORTDESCRIPTION"));
block.set("college",rs.getString("COLLEGEID"));
blocks.add(block);
}while(rs.next());
}else
{
return mapping.findForward("noCollegeSetup");
}
}}catch(SQLException e)
{
e.printStackTrace();
return mapping.findForward("sqlException");
}catch(Exception e)
{
e.printStackTrace();
return mapping.findForward("exception");
}finally
{
if(conn!=null)
conn.close();
}
request.setAttribute("BLOCKS", blocks);
return mapping.findForward("continue");
}
-----------------------------------------------------------------------------
this is my jsp
-----------------------------------------------------------------------------
<logic:iterate id="blocks" name="BLOCKS">
<tr>
<td class="centersubheading1"><bean:write name="blocks"
property="shortDesc"/></td>
<td class="centersubheading1"><bean:write name="blocks"
property="location"/></td>
<td class="centersubheading1"><bean:write name="blocks"
property="phoneNo"/></td>
<td class="centersubheading1"><bean:write name="blocks"
property="collegeShortDesc"/></td>
<td class="centersubheading1"> 'blocksModify.do?id=<bean:write
name="blocks" property="id" '><bean:message key="label.modify"/> </td>
</tr>
</logic:iterate>
-----------------------------------------------------------------------------
Hi,
Are you resetting the property correctly in your action class?
Using,
PropertyUtils.setSimpleProperty(form, "obj", List);?

Mano
