The problem is, ActionServlet seems to have modified the request, so in my closeAccount.jsp, i cannot retrieve the accountId parameter: request.getAttribute("accountId") returns null.

Is it possible that the accountId is saved in session scope instead of
request scope?
You need to specify the scope if you want to save it in "request" scope:
<action path="/closeAccount"
type="org.apache.struts.actions.ForwardAction"
parameter="/closeAccount.jsp" scope="request"/>

Posted by Robert Taylor <rt...@mulework.com>.
The accountId value is in the query string of the request and therefore must
be retrieved like:
String accountIdValue = request.getParameter("accountId");
