You can put that array list to either the sesion or request by calling setAttribute() method, like this:

request.setAttribute("arrName", arrObj);

Or

session.setAttribute("arrName", arrObj);

In your jsp page scriptlet, you can simply call request.getAttribute("arrName") or session.getAttribute("arrName") to get that array. Mind the type casting also.

If you use the core JSTL, you can loop through the array like this:

<c:forEach items="${arrName}" var="tmp">
...
</c:forEach>
