How to pass an object through html:link

[Raaja Gotluru]

Hi,

I am using struts 1.3. And i have a situation where I want to pass a bean object through html:link.

My code is:

<logic:iterate id="po" name="poList">
	<tr>
		<td align="center"><bean:write name="po" property="ponumber" />
		</td>
		<td align="center"><bean:write name="po" property="category" /></td>
		<td align="center"><bean:write name="po" property="itemname" />
		</td>
		<td align="center"><bean:write name="po" property="description" />
		</td>
		<td align="center"><bean:write name="po" property="uomaterial" />
		</td>
		<td align="center"><bean:write name="po" property="quantity" />
		</td>
		<td align="center"><bean:write name="po" property="rate" /></td>
		<td align="center"><bean:write name="po" property="totalamt" /></td>
		<td align="center"><bean:write name="po" property="podate" /></td>
		<td align="center"><bean:write name="po" property="vendorName" />
		</td>
		<% java.util.HashMap<Object,Object> params = new java.util.HashMap<Object,Object>();
		         params.put(po, po);
		         session.setAttribute("parameters", params);
		%>
		<td align="center"><html:link action="/modifyPo.do" paramId="po"
				paramName="po">Modify</html:link></td>
		<bean:define id="poid" name="po" property="poid" />
		<td align="center"><html:link action="/deletePo.do" paramId="poid" paramName="poid">Delete</html:link></td>
                               <!-- or -->
                                <!-- <td align="center"><html:link action="/deletePo.do" name="parameters">Delete</html:link></td>-->
	</tr>
</logic:iterate>	

Action:

 HttpSession session = request.getSession();
         //	java.util.HashMap<String, PurchaseOrderBean> hm =(java.util.HashMap<String, PurchaseOrderBean>) session.getAttribute("parameters");
//	java.util.Map<String, PurchaseOrderBean> poBean = (java.util.Map)request.getParameter("parameters");
			
	DynaValidatorForm frm = (DynaValidatorForm)form;
//	PurchaseOrderBean pOrder = (PurchaseOrderBean)hm.get("po");
	PurchaseOrderBean pOrder = (PurchaseOrderBean)request.getAttribute("po");
	BeanUtils.copyProperties(frm, pOrder);

If I use HashMap to pass the bean I am getting only the latest one.
If I use paramId and paramName then I am getting null values.

How to solve it.

Thanking you.

i think you need pass it with pagecontext .try it instead of session
