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!
Thanks in advance!
