 * Unit test for 4921329 ("default-charset" attribute of <parameter-encoding>
 * in sun-web.xml is ignored).
 *
 * This client invokes a JSP which retrieves the request charset, which must
 * correspond to the value of the default-charset attribute of the
 * parameter-encoding element in this web module's sun-web.xml.
 *
 * The JSP sets the response charset to be the same as the request charset.
 *
 * This client then checks to see if the response charset matches the value
 * of the default-charset attribute. The test fails if there is no match.
