Not anything new, but we can also increase the buffer size
<%@ page buffer="10kb" autoFlush="false" %><%@ taglib
uri="/WEB-INF/struts-bean.tld" prefix="bean" %><bean:define
id="emailStuff" toScope="request">
<html>
<body>
<h1><bean:write name="emailHeading"/></h1>
<p><bean:write name="emailBody"/></p>
</body>
</html>
</bean:define>
Also, if you define your action to extend IncludeAction, then by
having the path to template in the "parameter"
you could have the call to RequestDispatcher delegated to
IncludeAction like so :
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
// Set up attributes used by the template
request.setAttribute("emailHeading", "Test Heading");
request.setAttribute("emailBody", "This is some body text");
super.execute(mapping, form, request, response); // generate email
// Get the generated email from the request attribute
String emailStuff = (String)request.getAttribute("emailStuff");
// ...send the email
// forward to appropriate page
return mapping.findForward("success");
}
