I am sending an arrayList from a java file to a .jsp file

In order to receive that array I used the following code

var words = 
        [
            <c:forEach begin="0" items="${requestScope.WordList}" var = "word">
                word,
             </c:forEach>
        ];

however it is not working .. any Idea of how to do it ?

it is not working is too generalized, please be more specific! – Noob UnChained Apr 21 at 16:16

I don't think it is good practice to build JSON arrays this way. Just use a 3rd party library to do that. This kind of approach can create a lot of problems. – ubik Apr 21 at 16:28

Possible fix (Bad fix): 

var words = 
    [
        <c:forEach items="${requestScope.WordList}" var="word" 
         varStatus="status">
          "${word}"<c:if test="${not status.last}">,</c:if>
        </c:forEach>
    ];

OR

Convert the Java ArrayList to JSON String, and use JSON.parse() to get Javascript object.

As the type of word probably is string you will have to put quotes around ${word}. I.e. put "${word}", in the c:forEach. A secound problem would be, that you will have a comma at the end of the array definition. – user1983983 Apr 21 at 16:37

Edited the code! – Noob UnChained Apr 21 at 17:10
Comma at the end is fine with most browsers – Kyle Apr 21 at 17:11
Don't forget to escape the word string – Kyle Apr 21 at 17:12
