To provide internationalized AJAX components you need to do the following:
* Set the charset of the page to an encoding that is supported by your target languages. I tend to use UTF-8 because it covers the most languages. The following meta declaration in a HTML/JSP page will set the content type:
<m-eta http-equiv=""Content-Type"" content=""text/html; charset=UTF-8"">
* On the server-side component set the character encoding using the HttpServletRequest.setCharacterEncoding() method. Before you access the localized parameter using the HttpServletRequest.getParameter() call. In the case of UTF this would be request.setCharactherEncoding(""UTF-8"");.
A server-side component returning AJAX responses needs to set the encoding of the response to the same encoding used in the page.
response.getWriter().write("" <response>invalid </response>"");
For more information on using AJAX with Java Enterprise Edition technologies see AJAX and Internationalization and for developing multi-lingual applications see Developing Multilingual Web Applications Using JavaServer Pages Technology.
Some of the Google examples you cite don’t use XML at all. Do I have to use XML and/or XSLT in an Ajax application?
