No "indexed" access ala Struts?

["David M. Karr" <dm...@earthlink.net>]

I don't think this is available in the EL, but I'll ask just to make sure.

Struts property references allow you to specify array indices, like
"arrayIndexed[3]", when you have a method in your bean like this:

     public int getArrayIndexed(int index) {
       return (arrayName[index]);
     }

This is in addition to the more conventional references like "array[3]", with a
corresponding bean method of this:

    public int[] getArray() {
        return (this.arrayName);
    }

JSTL can deal with the latter, allowing a reference like "array[3]".  I don't
believe it will handle the former in any way.  Is that correct?  I've tried
some experiments and gone through the EL syntax, and I don't see anything like
this.

This is correct.  We considered the feature, but it wasn't a priority, and
nobody presented a compelling need for it.  In JSP 2.0, you could
accommodate it with a function; it could also always be added in a future
version of JSP.
