Accessing elements from an arraylist

[Mel Calvin]

Hi,

I have a LinkedHashMap that contains ArrayLists. Something like this:

    ArrayList list = new ArrayList();
    ArrayList list2 = new ArrayList();
    LinkedHashMap<Integer, ArrayList> map = new LinkedHashMap<Integer, ArrayList>();
    list.add(0, "list1 row1");
    list.add(1, "list1 row2");
    list.add(2, "list1 row3");
    list2.add(0, "list2 row1");
    list2.add(1, "list2 row2");
    list2.add(2, "list2 row3");
    map.put(0, list);
    map.put(1, list2);

How can I iterate over the elements in the arrays in the map in a JSP page?
Do I need to use the nested or logic tag? Can anyone show me an example of how to print out e.g. "list1 row1"?

Thanks.

ArrayList list = new ArrayList();
ArrayList list2 = new ArrayList();
LinkedHashMap<Integer, ArrayList> map = new LinkedHashMap<Integer, ArrayList>();
list.add(0, "list1 row1");
list.add(1, "list1 row2");
list.add(2, "list1 row3");
list2.add(0, "list2 row1");
list2.add(1, "list2 row2");
list2.add(2, "list2 row3");
map.put(0, list);
map.put(1, list2);
request.getSession().setAttribute("Map",map);
%>
<logic:iterate id="map1" name="Map" indexId="index" >
<table>
<tr>
<logic:iterate id="list1" name="map1" property="value">
<table><tr><td><bean:write name="list1"/></td></tr></table>

</logic:iterate>
</tr>
</table>
</logic:iterate>

Yes that is working, thanks. However that will print both arrays, I found out that to print only one of them can be done with:

  <logic:equal name="map" property="key" value="0">
    <bean:write name="list" /><br>
  </logic:equal>

A problem with this code is that it will print out the whole list. How would you retrieve/print out e.g. the first elements of all arraylists in one iteration and then the second elements etc?

hey i got the same problem today .
try this if you can use jstl:

<logic:iterate id="sourceList" name="${returnList[0]}">

[Mel Calvin]

ok, sourceList is the id of what?

regards.
