You can also do it like this
<%
Map map = new HashMap();
if(creditApplicationListDto.getBusinessLine()){ // assuming that you
make the "creditApplicationListDto" available as a scripting variable
map.put("label.bln", creditApplicationListDto.getBusinessLine());
}
if(creditApplicationListDto.getBusinessCard()){
map.put("label.bcard", creditApplicationListDto.getBusinessCard());
}
if(creditApplicationListDto.getSecuredCard()){
map.put("label.seccard", creditApplicationListDto.getSecuredCard());
}
if(creditApplicationListDto.getEquipExpress()){
map.put("label.equipExpress", creditApplicationListDto.getEquipExpress());
}
pageContext.setAttribute("map", map);
%>
<c:forEach items="${map.keySet}" var="key" varStatus="status">
<c:choose>
<c:when test="${not status.last}"><bean:write
message="${map[${key}]}"/>, </c:when>
<c:otherwise><bean:write message="${map[${key}]}"/></c:otherwise>
</c:choose>
</c:forEach>
All we did here is to create a collection which holds only the "true"
values. Note that you can do this in the DTO if you want to and expose
the collection through a getter
