Which part do you need help with specifically?
You did say you can pass parameters between JSPs.

Ya, i can get the value(i called it stall's id) from page A to page B. Then i need to place stallId in text box which in display table.

at jsp:

[CODE=html] <display:tabl e name="paramsArr " cellspacing="0" cellpadding="0" requestURI="" id="paramsArr" pagesize="40" class="table">
<display:colu mn property="name" escapeXml="true " sortable="true" titleKey="downl oadParameterFor m.name" style="width: 25%"/>
<display:colu mn titleKey="downl oadParameterFor m.value" style="width: 30%">
<html:text property="value Arr" size="29" maxlength="30"/>
</display:column>
<display:colu mn titleKey="downl oadParameterFor m.insert" style="width: 15%; padding-left: 15px" media="html">
<html:multibo x property="inser t" >
<c:set var="index" value="${index+ 1}"/>
</display:column>
</display:table>[/CODE]

Backend :

[CODE=java] String[] paramCons = Constants.PARAM _NAMES;
List paramsArr = new ArrayList();
String[] result = new String[paramCons.lengt h];
String[] noValue = new String[paramCons.lengt h];

for(int i=0; i<paramCons.len gth; i++){
ParameterDto paramDto = new ParameterDto();
paramDto.setNam e(paramCons[i]);
paramDto.setVal ueArr(noValue);
if(paramCons[i].equals("MERCHA NT") && (parameterForm. getStallId()!=n ull && !parameterForm. getStallId().eq uals(""))){
Stall stall = stallMgr.getSta ll(new Long(parameterF orm.getStallId( )));
paramDto.setNam e("MERCHANT") ;
result[i] = stall.getStallI d(); // this is stallId, eg: 1234778
paramDto.setVal ueArr(result);
}
paramsArr.add(p aramDto);
}
[/CODE]
** paramDto is a bean


I hope those codes will provide more explanation/understand to you....What i need to solve is display the stallId in the correct text box in display tag. Thank for reply.

I have make it already, anyway, thank you very much on reply!
Below is the solution, if anybody has same problem with me, can have look! :)
Backend code still remain, but change setValueArr( ) to setValue( ), which is set value as string, not string[] anymore.

But there is changes at jsp:
<c:set var="index" value ="0"/>
<c:set var="valueIndex " value="0"/>
<display:tabl e name="paramsArr " cellspacing="0" cellpadding="0" requestURI="" id="paramsArr" pagesize="40" class="table">
<display:colu mn property="name" escapeXml="true " sortable="true" titleKey="downl oadParameterFor m.name" style="width: 25%"/>
<display:colu mn titleKey="downl oadParameterFor m.value" style="width: 30%" >
<html:text property="value Arr" size="29" maxlength="30" value="${params Arr.value}" />
<c:set var="valueIndex " value="${valueI ndex+1}"/>
</display:column>
<display:colu mn titleKey="downl oadParameterFor m.insert" style="width: 15%; padding-left: 15px" media="html">
<html:multibo x property="inser t"><c:out value="${index} "/></html:multibox>
<c:set var="index" value="${index+ 1}"/>
</display:column>
</display:table>
