I wasn't looking in the JSTL spec, once I looked there I found an example I could extrapolate from. Thanks for pointing me in the right direction David. BTW your example was exactly what I needed also, so thanks again.

If you're using "logic-el", then you might as well use the JSTL, which is more suited for this. Note that your sample code differs slightly from what you said in english, but this should be close enough for you. If you want to reverse the test, change "empty" to "not empty". Note that this code hasn't been compiled. <c:choose> <c:when test="${empty param.body}"> Do something. </c:when> <c:otherwise> Do something else. </c:otherwise> </c:choose> I suggest you read the JSTL specification. -- =================================================================== David M.
