If you're using Struts 2 use the webwork Iteration tags
<ww:iterator /> Iterates over a collection.
<ww:generator /> Generates iterators.
<ww:append /> Appends several iterators.
<ww:subset /> Gets a subset of an iterator.
<ww:merge /> Merges several iterators into one.
<ww:sort /> Sorts an iterator

Subject: Possible to iterate through a java.util.Set using Struts 1?
>
> Hi everyone!
>
> I've just started learning Struts (1) and this is my current problem:
> I have a java.util.Set which is saved in the current session and I'm trying
> to use Struts for checking if it's not empty and in that case iterating
> through it (from a JSP). This is the beginning of that code:
>
> <logic:notEmpty scope = "session" name = "skillsFound">
> <logic:iterate collection = "skillsFound" id= "thisSkill" scope
> = "session">
>
> When I try stepping through the code, the logic:notEmpty tag is handled just
> fine, but when I get to the logic:iterate tag I get this exception:
>
> javax.servlet.jsp.JspException: Cannot create iterator for this collection
>
> Does anyone know if it's possible to iterate through a Set using Struts (1
> and not 2) in any way?
>
> I could always make it work by writing a scriptlet and iterate through it
> the regular Java way, but I'm trying to use as much Struts as possible since
> I'm doing a thesis where one of the issues is what the benefits of Struts
> are. (And besides, I've read that using scriptlets is "bad style" nowadays.)

> So if anybody knows a Struts solution to this, I'd be very grateful!
