Is there an empty keyword in Struts 2 (like in JSP)?
For example in JSP I write:
<c:if test="${empty var}">
Thanks

A:
Just test for null.
And to acheive the same effect than the JSTL empty keyword with strings (which means "null or empty"), you need two checks (yes it is tiresome):
<s:if test="foo != null && foo != ''">

Yeah this is what I'm doing now, but it's not the same check "empty" does. For example an array with no elements should be empty, a blank string like " " too, etc. Thanks though.
