You can use c:when/c:otherwise.

Code:
<c:when test="${empty jobs}">
  No search result found.
</c:when>
<c:otherwise>
  <c:forEach var="current_outer" items="${list}">
      <tr>
          <td><c:out value="${job.title}" /></td>
      </tr>
  </c:forEach>
</c:otherwise>
You can also negate a test with "not". The following is equivalent to the above.

Code:
<c:when test="${not empty jobs}">
  <c:forEach var="current_outer" items="${list}">
      <tr>
          <td><c:out value="${job.title}" /></td>
      </tr>
  </c:forEach>
</c:when>
<c:otherwise>
  No search result found.
</c:otherwise>
