Question

                            ${test}
                             <c:forEach items=" ${test}" var="sharedType">
                                  ${sharedType}<br/>
                                 <c:if test="${sharedType == 2}" >
                                     <span class="tweet-button"></span>
                                 </c:if>
                                 <c:if test="${sharedType == 1}" >
                                     TEST
                                     <a href="#" class="fbshare-button">Share</a>
                                 </c:if>
                            </c:forEach>

The integer list is 1,2,3.
On my page, it show [1,2,3] for ${test}, and “[1” “2” “3” for ${sharedType} in 3 iterations. Looks like JSTL think it is a String separated by comma rather than a list.
The code to generate the list in java is:

List<Integer> test= new ArrayList<Integer>();
            test.add(1);
            test.add(2);
            test.add(3); 

I have been struggling with this for a while, can anyone help me with this? Thanks.

Just checked it in my app and so put it as an answer: try removing space from items=" ${test}". Otherwise, you’re executing equivalent of this java expression " " + testList. Obviously, the result is not a list.

and “[1” “2” “3” for ${sharedType} in 3 iterations
Most likely there was only one iteration and you’re seeing the result of test.toString() call.
