This section describes how Sun Java System Web Server 7.0 determines the character encoding for the servlet request and the servlet response. For information about encodings, see http://java.sun.com/j2se/1.5.0/docs/guide/intl/encoding.doc.html.
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 Element.
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 Element.
When processing a servlet response, the server uses the following order of precedence, first to last, to determine the response character encoding:
The ServletResponse.setContentType () method or the ServletResponse.setLocale () method.
The default encoding, which is ISO-8859–1.
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, 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 Element
