How to find whether HashMap is empty/null in JSTL?

Question

I have something like this in my controller:

model.attribute("hiringManagerMap",hiringManagerMap);

I am accessing this hiringManagerMap in my jsp and displaying the string values in option.

I need to display that field only when the Map is not null.

I tried doing <c:if test=${!hiringManagerMap['empty']}>. But, it doesn't work. It does not work even when the Map isn't empty.

Please help!!

Solution

Try this <c:if test="${not empty hiringManagerMap}">. It should check for both null and empty. Please read this for more details if you need to check other collections or maps for being empty.
