/*
 * Unit test to ensure that <parameter-encoding> subelement of <sun-web-app>
 * takes precedence over <parameter-encoding> subelement of
 * <locale-charset-info>, which has been deprecated.
 *
 * In its sun-web.xml, this web module specifies two parameter-encoding
 * elements, each with a form-hint-field attribute: the value of the 
 * form-hint-field attribute of the <parameter-encoding> subelement of 
 * <sun-web-app> is 'sunWebAppFromHintField', whereas the value of the
 * form-hint-field attribute of the <parameter-encoding> subelement of
 * <locale-charset-info> is 'localeCharsetInfoFormHintField'.
 *
 * Client appends to the request URI two query parameters named after the
 * form-hint-field attributes. The two query parameters, which would normally
 * represent hidden form fields, specify different request charsets as their
 * values.
 *
 * Container is supposed to set the request encoding to the value of the query
 * parameter named 'sunWebAppFromHintField', which is supposed to take
 * precedence over the query parameter named 'localeCharsetInfoFormHintField'.
 *
 * JSP that is the target of the request retrieves the request encoding and
 * assigns it as the response encoding, which is checked by this client by
 * parsing the Content-Type response header.
