How to code this if structure in JSTL?

can we code the following if condi开发者_StackOverflowtion inside the <c:if test="${}> ?

if((myFlag == true) && (flag1 != null || flag2 != null || flag3 != null))

---

Sure:

<c:if test="${myFlag and (not empty flag1 or not empty flag2 or not empty flag3)}">

PS: Using a null-test to decide a flag instead of true/false is bad style and should be avoided, if possible.

<c:if test="${myFlag && (flag1 != null || flag2 != null || flag3 != null)}">

Simple, isn't it?
