No. You could use an array of String or ArrayList of Integer, whatever.
The logic:iterate will look slightly different though.
> Question2 how do you set up the iterate tag to get both values?
You'll need to write them out using bean:write
If you have a collection of bean:
MyBean
String valueA;
String valueB;
(with getters and setters)
Then you can display them as follows:
(in your action)
//setup your collection
...
//then add to request
request.setAttribute("myCollectionOfMyBean", coll);
// then forward to your jsp
(in your jsp)
<logic:iterate id="itm" name="myCollectionOfMyBean">
<bean:write name="itm" property="valueA"/>
<bean:write name="itm" property="valueB"/>
</logic:iterate>
See, the logic:iterate sets up a scripting variable named 'itm' so that
the bean:write tag can use it to call getValueA() and getValueB().
