Nope. "items" should evaluate to a collection.
In JSTL it would be something like the below code to solve your
problem (I haven't tested it, Just wrote it on top of my head)

<c:if test="${creditApplicationListDto.businessLine}">
   <bean:message key="label.bln"/>
   <c:set var="found" value="true"/>
</c:if>
<c:if test="${creditApplicationListDto.businessCard}">
   <c:choose>
      <c:when test="${found}">
        ,&nbsp;<bean:message key="label.bcard"/>
      </c:when>
      <c:otherwise>
        <bean:message key="label.bcard"/>
        <c:set var="found" value="true"/>
      </c:otherwise>
   </c:choose>
</c:if>
<c:if test="${creditApplicationListDto.securedCard}">
   <c:choose>
      <c:when test="${found}">
        ,&nbsp;<bean:message key="label.seccard"/>
      </c:when>
      <c:otherwise>
        <bean:message key="label.seccard"/>
        <c:set var="found" value="true"/>
      </c:otherwise>
   </c:choose>
</c:if>
<c:if test="${creditApplicationListDto.equipmentExpress}">
   <c:choose>
      <c:when test="${found}">
        ,&nbsp;<bean:message key="label.equipExpress"/>
      </c:when>
      <c:otherwise>
        <bean:message key="label.equipExpress"/>
        <c:set var="found" value="true"/>
      </c:otherwise>
   </c:choose>
</c:if>


Look how large the chunk of code is. Better way of doing it is by
having some sort of an utility method or using a tag as "Jim"
suggested
