For starters, your Java code in ajaxTest.jsp is incorrect and won't compile. What did you want it to do?

As for the array, you can't do it like that. You can either return a delimited string which you can split using split() (and, hey presto, you have an array!), or use JSON or XML and parse the response.

PS. I've changed the thread title to give the problem a better description.
