JSTL foreach question (vector in a hashmap)

[Seamus Loftus]

Hello all,
I am trying to get a nested vector out of a hashmap. The problem is that the JSTL line returns a object and not the vector I need. Is there a way to convert this?

Here is a code snippet:
<c:forEach var='hashitem' items='${queryFormBean.hash}'>
<c:set var="hashsubitem" value="${hashitem.key}"/>
<c:forEach var='vectval' items='${hashsubitem}'>
- <c ut value='${vectval}'/>, <c ut value='${hashitem.value}'/><BR>
</c:forEach>
</c:forEach>

Later,
Seamus

The EL is interpretive. It will "return" whatever the object really is.

Secondly, in the following lines;

<c:set var="hashsubitem" value="${hashitem.key}"/>
<c:forEach var='vectval' items='${hashsubitem}'>

you are setting hashsubitem from the key of the Map.Entry instance and then attempting to iterate over that. Is the vector really the key of your Map? Or did you mean to iterate over the value?

If so, the line should be:

<c:set var="hashsubitem" value="${hashitem.[B]value[/B]}"/>
