How do you extract data from ArrayList of Maps and the classical Iterator?

Question

Hello guys.
I ran into this great doozie when I was coding this project I am working on. I have created a randomized question pool for a test so that no two tests with the same ID are alike. I grab a resultset from the DB and push the values through a randomizer. After that, then I stick a Map of the entire object into an ArrayList. Each object is then one complete question. So I have X objects (questions) in the ArrayList then (this is determined by a value in the DB in the test table).
I have the following code setup:
Map m = (Map)i.next();
          Iterator keys = m.keySet().iterator();
          while (keys.hasNext())
               key = keys.next();
               value = (String)m.get(key);
The key - data pair always comes out in the same order. What I am trying to do is populate a test (form values) for this. Is there a way that I can do this in JSP? The key map is 100% new to me.
I want to put the test into a table layout. the typical HTML boiler plate stuff is a cinch, but how would I get the information into a textfield? I can print out the key value pairs, but I guess I get lost in the logic when trying to get these to print in a specific order. Any help you can provide would be highly appreciated.
Kind Regards,
Josh

You can use the JSTL c:forEach tag for that.
