Harald, I just realized that the XmlResponseWriter you referrred to is from
trinidad jars; We are actually having a centralized valve at tomcat level
that does the redirection.
We would want that piece of code to be independent of any dependencies on
any of the UI frameworks.
Is it possible to write some thing like:
final boolean isPartialRequest =
"true".equals(req.getHeader("Tr-XHR-Message"));
response.setContentType("text/xml");
PrintWriterout = response.getWriter();
if (isPartialRequest) {
out.println("<?xml version=\"1.0\"?>");
out.println("<?Tr-XHR-Response-Type ?>\n");
out.println("<redirect>");
out.println("</pageURL>");
out.println("</redirect>");
out.close();
}else {
response.sendRedirect(pageURL);
}
Thanks and Regards,
Samba
