how do I check the size of the collection

[Jayaraman Dorai <ja...@Wellogic.com>]

I have a collection which I want to iterate in the jsp page. If the collections size is 0, I want to display a message no elements in the collection. Is there any struts tag for this.
 
 
Thanks

The bean:size tag can do this. 

http://jakarta.apache.org/struts/doc-1.0.2/struts-bean.html#size

You can then apply logic:equals to the result.

Though, I usually wrap collections in a helper object that can do things
like this for you.
