I am sorry, I think I conveyed my need differently. I do not need a
decorator.
My need is to create columns from database.
My need is 4 static columns but rest all columns coming fro database.
So I have build 2 beans for that.
bean1 -- name, value from database.
Bean 2 - 4 static columns + arraylist of bean1
in request i store arraylist of bean2.
my jsp code is this
<display:table name="bean2" >
<display:column property="name" title="School Name" ></display:column>
<c:forEach var="cl" items="bean2.bean1">
<display:column title="${cl.title}" property="${cl.value}" />
</c:forEach>
<display:column property="allocatedAmt" format="{0,number,0,000.00} $"
title="Total Allocated $" ></display:column>
<display:column property="totalOfAllPrograms" format="{0,number,0,000.00}
$" title="Current Total $" ></display:column>
<display:column property="difference" format="{0,number,0,000.00} $"
title="Difference" ></display:column>
</display:table>
But with below code i get following error
Error looking up property "${cl.currYearExpenditure}" in object type bean2
So it is not gonig to bean1. it is looking for the object in bean2.
Any help will be appreciated.
Thanks and regards,
Jill.

Have you tried to use a Decorator?
It's very simple, eg:
1) You must to use the atribute decorator in a column, whit the class that
do the decoration: in my example is ExpedienteDecorator. In this class
you've differents methods, and you use them like a property in the colum,
eg, property="radioButton"
<display:table name="table" class="displaytag"
decorator="es.dap.ecsi.displaytag.decorator.ExpedienteDecorator">
<display:column style="width=4%;" media="html"
property="radioButton" title="SELECCIONAR PARA VER
CONTROL"></display:column>
2) In the Decorator class I've the method radioButton, that returns and
String whit code html generate dinamycally with a radio button that has a
javascript method with differents parameters for each row.
public String getRadioButton() {
//ExpedienteView is the actual table type, and you can
access to each row with getCurrentRowObject and after accest to their
fields
with the accessors methods.
ExpedienteView row= (ExpedienteView)getCurrentRowObject();
int campagna = row.getCampagna();
int expediente = row.getExpediente();
String control = row.getControl();
String result = "<input type=\"radio\" name=\"radio\"
id=\""+expediente+"\" onclick=\"actualizaDetalle("+expediente+");
parametrosExpedientes("+campagna+","+expediente+");\" />";
return result;
}
I hope that you had understood my explanation, sorry for my english.
