Answer 1

You can do this in several ways :

1) You can use renderRequest.setAttribute("my-array", array);

2) You can put your data into a session

request.getPortletSession().setAttribute("my-array", array);

In the second case don't forget to delete your element from the session when you don't need it any more.
