use*_*341 5 jsp servlets jdeveloper utf-8 character-encoding
当我试图在我的 JSP 页面中显示中文字符时，它会显示垃圾字符。
我做错了什么？
我在顶部的 JSP 中包含了以下行，即使是现在，问题也没有得到解决：

在这里，问题在于CDATA. 在 Servlet 中，我们用于iso-8859-1以 xml 格式发送 xml 响应。当我们尝试使用 时UTF-8，未生成 xml 格式的响应。因此，我们不是将 xml 响应从 servlet 发送到 jsp，而是以 html 格式发送该响应并在 jsp 页面上显示为 html 响应。这有助于解决我的问题。
sb.append("<option value="+org.getOrgId()+">"+dislayName+"</option>");
response.setContentType("text/html;charset=UTF-8");
response.setHeader("Cache-Control", "no-cache");
response.getWriter().write(sb.toString());
$('#orgId').html("<option value=\'-1\'>------------ Select Organization ------------</option>"+xmlResponse);
