The above tag is to check whether parameter name is null or not. If it is not null then it prints out the sentence and it prints nothing if the value is null.


< c:if test="${param.name ne null}">< /c:if>

A test shows that parameter name contains value of ${param.name} via "ne" operator

Above codes are working similarly with the previous codes. We just want to test JSP notation “ne” for not equal function as what “!=” does.


< c:if test="${not empty(param.name)}">< /c:if>



A test shows that parameter name contains value of ${param.name} via empty operator.
