我的代码:

< textarea id =preview-form-commentname =preview-form-comment> $ {fn:escapeXml(param.preview-form-comment)}< / textarea>

好吧,简单的方法:
你的servlet定义了:
String comment = request.getParameter(preview-form-comment);
request.setAttribute(anydata,comment);
并在您的textarea中写入:
< textarea id =preview-form-commentname =preview-form-comment> $ {anydata}< / textarea>
运行:)祝你好运
