Thank you Hans,
that trick will do for some of the sorting problems I have. By the way
bought your book and have toasted a lot of bread since ;). My JSP bible.
Xtags has a built in sort function. Might sorting be considered in future
releases of jstl?
And one more for the weekend, what would be the best way to get a total sum
of N numbers from a xml query (jstl of course)?
Thanks,
