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:

 <display:table name="paramsArr" cellspacing="0" cellpadding="0" requestURI="" id="paramsArr" pagesize="40" class="table">
            <display:column property="name" escapeXml="true" sortable="true" titleKey="downloadParameterForm.name" style="width: 25%"/>
            <display:column titleKey="downloadParameterForm.value" style="width: 30%">
                <html:text  property="valueArr" size="29" maxlength="30"/>
            </display:column>
            <display:column titleKey="downloadParameterForm.insert" style="width: 15%; padding-left: 15px" media="html">
                <html:multibox property="insert" >
                <c:set var="index" value="${index+1}"/>
            </display:column>
        </display:table>

Backend :

 String[] paramCons = Constants.PARAM_NAMES;
        List paramsArr = new ArrayList();
        String[] result = new String[paramCons.length];
        String[] noValue = new String[paramCons.length];
 
        for(int i=0; i<paramCons.length; i++){
            ParameterDto paramDto = new ParameterDto();
            paramDto.setName(paramCons[i]);
            paramDto.setValueArr(noValue);
            if(paramCons[i].equals("MERCHANT") && (parameterForm.getStallId()!=null && !parameterForm.getStallId().equals(""))){
                Stall stall = stallMgr.getStall(new Long(parameterForm.getStallId()));
                paramDto.setName("MERCHANT");
                result[i] =  stall.getStallId(); // this is stallId, eg: 1234778
                paramDto.setValueArr(result);
            }
            paramsArr.add(paramDto);
        }
 

** 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:table name="paramsArr" cellspacing="0" cellpadding="0" requestURI="" id="paramsArr" pagesize="40" class="table">
<display:column property="name" escapeXml="true" sortable="true" titleKey="downloadParameterForm.name" style="width: 25%"/>
<display:column titleKey="downloadParameterForm.value" style="width: 30%" >
<html:text property="valueArr" size="29" maxlength="30" value="${paramsArr.value}" />
<c:set var="valueIndex" value="${valueIndex+1}"/>
</display:column>
<display:column titleKey="downloadParameterForm.insert" style="width: 15%; padding-left: 15px" media="html">
<html:multibox property="insert"><c:out value="${index}"/></html:multibox>
<c:set var="index" value="${index+1}"/>
</display:column>
</display:table>
