JSTL if-else sample with c:out

This is my memo. We can write JSP with using c:choose and c:when, c:otherwise behave as if-else syntax. This example inclues c:forEach and sql:query also. Getting some data from database with sql:query, and show them with c:forEach loop and change display strings after checking some data in c:choose section.

<sql:query var="rs" dataSource="jdbc/DS">
  SELECT ID,ACSII_NAME as ANAME, DISP_NAME as DNAME FROM PERSON ORDER BY ID;
</sql:query>
<c:forEach var="row" items="${rs.rows}"><tr>
  <td>${row.id}"</td>
    <c:choose>
      <c:when test="${row.dname != null && row.dname != ''}">
        <td><c:out value="${row.dname}" /></td>
      </c:when>
      <c:otherwise>
        <td><c:out value="${row.aname}" /></td>
      </c:otherwise>
    </c:choose>
</tr></c:forEach>
