Wouldn't this be nice?
<c:join items='${employees}' delim=','/>

Maybe I'm alone but it seems like I'm often having to display what I'm
iterating over with forEach and usually I need something displayed
'between' each iteration, such as a comma after each name if iterating
over names.
Actually come to think of it, I'm being an idiot:) I'm so used to my Tag
where I pass in a collection and it basically does what you are doing
below.
I guess I was thinking of giving forEach too much power with something
like...
<c:forEach items='${collection}' property='someProperty'
append=', ' ignoreLast='true'/>
Which might be..
<c:forEach items='${employees}' property='lastName' append=', '
ignoreLast='true'/>
Which would spit out a comma separated list of lastNames from the
collection of Employee beans in employees.
Then again this is probably dumb to delegate that much to a forEach tag.
sorry been a long week and it aint over:)
