Struts Action返回xml

struts中的action如何返回xml，google之，so easy！

在struts.xml中配置

<action name="chart" class="chartAction">
    <result name="xmlMessage" type="plainText"></result>
</action>

哦，原来result中name和type是这样的，那么action怎么写呢？？

public void test() throws IOException{
    HttpServletResponse response = ServletActionContext.getResponse();
    PrintWriter out = response.getWriter();
    response.setContentType("text/xml;charset=UTF-8");
    //返回xml
    out.write(xml);
}

OK，测试一下吧...
