forEach not working

I'm adding a forEach statement in the index.jsp page and it's not working. I'm using netbeans and item.product.description line is highlighted and the error/warning is "Multiple Breakpoints". I'm not sure what Multiple Breakpoints mean.





web.xml

It means something about the breakpoints you've configured so you can do debugging in Netbeans. It doesn't mean anything about your code at all. Did the message actually prevent you from running that code, or did you just not try when you saw the message?

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
