JSTL forEach

[Bob Rivers]

Hi,

I'm new to JSTL, and I'm trying to understand the forEach interator.

Looking through the example provided (jstl-standard-examples.war)

<c:forEach var="customer" items="${customers}">
<cut value="${customer}"/><br>
</c:forEach>

The output is someting like this:

[1] Richard, Maurice 05/15/1935 123 Chemin Royal Montreal Canada
[2] Mikita, Stan 12/25/1947 45 Fisher Blvd Chicago USA (320)876-9784

Ok, no problem. customers is a Vector of customer objects.

How do I get a specific value of the vector? Let's say that I want to
print only the birthdate? Or, what if I want to put each value inside
a table colunm (ex.: <td>name</td><td>birthdate</td>...).

TIA,

Bob

Presumably each member of the customers collection is an object that
has accessor methods for its properties. That being the case, you code
something like this to get the two table cells you mention above:

<td><cut value="${customer.name}"/></td><td><cut
value="${customer.birthdate}"/></td>

The accessor methods "getName" and "getBirthdate" of the customer
object will be called.

But dates a best used with <fmt> than a <cut>

But dates a best used with <fmt> than a <cut>

Agreed, that gives you control over just how the date will appear on
the web page.
