accesss to indexed variable in bean

Hello All,

I'm trying to use JSTL to access and indexed property on a bean.

The bean accessor looks like:

public List getRecord(int index) {

and my JSP looks like this:

<c:forEach items="${requestScope.dataBean.record[0]}" var="record">

However, this doesn't work, complaining that:

Unable to find a value for "record" in object of class "DataBean" using operator "."

Can anyone help me?

Myself, I've never much cared for indexed properties, so I've always used a slightly different pattern which is known to be EL-friendly.

Rather than an indexed property, I usually have a discrete property that returns an array (or List, or Map, or whatever collection) and use the array indexing mechanism on the returned collection.

For example:

which can be used in the EL as

In your example, it looks like each of your indexed properties is a List, so you could define an accessor such as:

and use it in your page as:
