Help with <c:forEach> and HashMap

[Luis Pedro]

Dear all,
I've an HashMap of type model <String, HahsMap>. The second HashMap
is of type <String, Object>.

I'm trying to iterate in this HashMap in my jsp page and things
like:
<c:forEach var="element" items="${model.products.product}">
<cut value="${element.name}"/>

and

<c:forEach var="element" items="${model.products.provider}">
<cut value="${element.name}"/>

But I want to access to product and provider simultaneously.
I tried
<c:forEach var="element" items="${model.products}">
<cut value="${element.product.name}"/>
<cut value="${element.provider.name}"/>

But this does not work:
javax.el.PropertyNotFoundException: Property 'product' not found on
type java.util.HashMap$Entry

Any idea on how to solve this?

Thanks very much in advance for your time.

Best regards,

Luis

Looks like you are getting objects of type HashMap.Entry in 'element'
variable. You may have to use key and value (from Entry type) in some
way to get at what you want.

Hi there,
Thanks very much for the help. Great link. Anyway, just wanted to
share my solution.
Instread of the HashMap <String, HahsMap> with a second HashMap
of type <String, Object> I decided to just create a HashMap <Object,
Object> and then:
<table border=1>

<tr>
<c:forEach items="${model}" var="element">
<tr>
<td>${element.value.name}</td>
<td>${element.key.name}</td>
</tr>
</c:forEach>
</tr>
</table>

Hope it helps someone.

Best regards,

Luis
