there is no conditions like if else in jstl instead of that jstl provides following 

<c:choose>
  <c:when test="${condition1}">
    ...
  </c:when>
  <c:when test="${condition2}">
    ...
  </c:when>
  <c:otherwise>
    ...
  </c:otherwise>
</c:choose>

JSTL comes with <c:choose>, <c:when> and <c:otherwise> tags to implement if-then-else type logic within JSPs. Check out JSTL Core Choose Tag for a basic example.

<c:choose>
    <c:when test="${a boolean expr}">
      <!-- // do something -->
    </c:when>
    <c:when test="${another boolean expr}">
      <!-- // do something else -->
    </c:when>
    <c:otherwise>
      <!-- // do this when nothing else is true -->
    </c:otherwise>
</c:choose>

The JSTL, surprisingly, is documented, and has an official tutorial. Google is your best friend.

You're looking for c:choose, c:when and c:otherwise:

<c:choose>
    <c:when test="${status.message == 'Access Denied'}">
        ...
    </c:when>
    <c:otherwise>
        ...
    </c:otherwise>
</c:choose>
