Appendix A
Internationalization IssuesThis appendix covers internationalization as it applies to the following:
ServletsThis section describes how the Sun ONE Web Server determines the character encoding for the servlet request and the servlet response.
For encodings you can use, see:
http://java.sun.com/j2se/1.4/docs/guide/intl/encoding.doc.html
Servlet Request
When processing the servlet request, the server uses the following order of precedence, first to last, to determine the character encoding for the request parameters:
- The ServletRequest.setCharacterEncoding() method.
- A hidden field in the form, if specified using the form-hint-field attribute of the parameter-encoding element in the sun-web.xml file. For more information about this element, see "parameter-encoding."
- The character encoding specified in the default-charset attribute of the parameter-encoding element in the sun-web.xml file. For more information about this element, see "parameter-encoding."
- The default encoding, which is ISO-8859-1.
Servlet Response
When processing a servlet response, the server uses the following order of precedence, first to last, to determine the response character encoding:
To specify the character encoding that should be set in the Content-type header of the response if the response locale is set using the ServletResponse.setLocale method, you can use the locale-charset-map under the locale-charset-info element in the sun-web.xml file. For more information about this element, see "locale-charset-info."
JSPsA JSP page uses a character encoding. For encodings you can use, see:
http://java.sun.com/j2se/1.4/docs/guide/intl/encoding.doc.html
The encoding can be described explicitly using the pageEncoding attribute of the page directive. The character encoding defaults to the encoding indicated in the contentType attribute of the page directive if it is given, or to ISO-8859-1.
