how to check a 'set' variable in Struts tag/JSTL

[lixin chu <li...@yahoo.com>]

hi,
how to check a 'set' variable using JSTL or Struts
tags ? 

for example, I have a variable called 'Roles' which is
a Set. In a JSP, I want to check if
'Admin'/'Guest'/'User' is in the Set. How do I do this
? Could not find a suitable tag to handle this.

thanks
li xin

Unfortunately I haven't found a tag in JSTL or Struts that does this (I 
think there should be one in JSTL though - also a contains for Lists). 
My guess is there is probably a gneric one out there that someone 
created. If not, time to make one and share:)
