Solution 1 - Jstl

This look like a duplicate of https://stackoverflow.com/questions/6219730/jstl-conditinal-check.

The error is having the && outside the expression. Instead use

<c:if test="${ISAJAX == 0 && ISDATE == 0}">

Solution 2 - Jstl

If you are using JSP 2.0 and above It will come with the EL support: so that you can write in plain english and use and with empty operators to write your test:

<c:if test="${(empty object_1.attribute_A) and (empty object_2.attribute_B)}">

Solution 3 - Jstl

Recommendation:

when you have more than one condition with and and or is better separate with () to avoid verification problems

<c:if test="${(not validID) and (addressIso == 'US' or addressIso == 'BR')}">

Solution 4 - Jstl

Just in case somebody needs to check the condition from session.Usage of or

<c:if test="${sessionScope['roleid'] == 1 || sessionScope['roleid'] == 4}">
