Display tags in the Spring Applications

[pradeep dahiya9]

Hi If any one has used the Display Tags with Spring .
Please help me ..
I am populating data in the form of HashMap as a Model.
How can I populate data in the Display Tags.


My Code for Data is :--

public class InventoryController implements Controller {
protected final Log logger=LogFactory.getLog(getClass());
private ProductManagerService productManager;

public void setProductManager(ProductManagerService productManager) {
this.productManager = productManager;
}
public ModelAndView handleRequest(HttpServletRequest Request,HttpServletResponse response)throws ServletException,IOException
{ String now=(new Date().toString());
logger.info("Returning hello view"+now);
Map myModel = new HashMap();
myModel.put("now", now);
myModel.put("products", this.productManager.getProducts());
return new ModelAndView("hello", "model", myModel);
}
}


For Displayig data i have code as :--

<h3>Products</h3>
<h2>Display Tag Start</h2>

<display:table name="products">
<display:column property="description" /><c:out value="${model.products.description}"/>
<display:column property="price"/><c:out value="${model.products.price}"/>
</display:table>

<h2>Display tag end </h2>

[ code][/code ] tags next time please.

I suggest you recheck the way Display Tag works.

1) Your definition is wrong, don't include the c:out stuff
2) the table name should be model.products

<display:table name="model.products">
  <display:column property="description" />
  <display:column property="price"/>
</display:table>

What does productManager.getProducts() return? See if you have data populating into the model.

Are you getting "Nothing found to display" message on your jsp or nothing at all?

Hello thanks for the reply,

I am geting the data from this productManager.getProducts()
in the form of hashMap.

I understand in the display tags we have to give the name of the colllection but it is not taking up..

Plz suggest me.

What does your HashMap look like? What is the key & the value?

<h2>Display Tag Start</h2>

<display:table name="prod" export="true" pagesize="1">
<display:column property="id" sortable="true"/>
<display:column property="description" />
<display:column property="price"/>
</display:table>
<h2>Display tag end </h2>
