Js Array from java List

Question

I got to create an Array list this...
new Array('Requerimiento', '89', 'Esto es un requerimiento\nOtra l�nea', 'Producci�n', '90', 'Hola\nHola', 'Release', '91', '<BR>'));
exactly like this from a java List.. so i got to replace 'Requerimiento' for ((myObj)list.get(0)).getName(), replace '98' for ((myObj)list.get(0)).getId(). replace 'Esto es un requerimiento\nOtra l�nea' for ((myObj)list.get(0)).getDesc() and then the same cyclye but for position 1 in the list.
The array is dynamic so i can has as elements as the list has so i have no idea what to do and did this...
     var taskTypes = new String();
                     List taskTypeList = timeKeeping.getValidTaskTypes(from, to);
     for(int x = 0, i = 0; x < taskTypeList.size(); x += 3, i++) {
          TaskType tt = (TaskType) taskTypeList.get(i);
     %>
if(i + 1 == taskTypeList.size()) {
     taskTypes.concat("<%= tt.getName() %>" + ',' + "<%= tt.getId() %>" + ',' + "<%= tt.getName() %>");
} else {
     taskTypes.concat("<%= tt.getName() %>" + ',' + "<%= tt.getId() %>" + ',' + "<%= tt.getName() %>" + ',');
<%
%>but it doesn't work out...
help plz ! Thanks a lot.

Answer 1

String.concat() does not add the string to the string, it returns a new string combining the 2, so you'd have to do this:
taskTypes = taskTypes.concat("<%= tt.getName() %>" + ',' + "<%= tt.getId() %>" + ',' + "<%= tt.getName() %>");
But, you need to be writing JavaScript... (I assume it's an array of arrays...)
var aArray = new Array();
<%
List taskTypeList = timeKeeping.getValidTaskTypes(from, to);
for(int x = 0, i = 0; x < taskTypeList.size(); x += 3, i++) {
   TaskType tt = (TaskType) taskTypeList.get(i);
%>
aArray[aArray.length] = new Array('<%= tt.getName() %>', '<%= tt.getId() %>', '<%= tt.getName() %>' ... );
<% } %>
