What I would like to avoid is specifying a page directive at the beginning of every JSP.
As I understand, without the following line, the default for the Content-Type for the page will be set to "text/html;charset=ISO-8859-1".
<%@ page contentType="text/html; charset=UTF-8" %>
Is there a configuration option that does the same thing without having to explicitly set the charset for every single JSP file in an application?
You can add the following to web.xml
