編碼問題
JSP:

FromBean:

InputForm input = (InputForm) form;// TODO Auto-generated method stub

return mapping.findForward( "forward ");
}
}
我在JSP的文本框輸入簡體中文，繁體中文，提交請求后顯示都是亂碼，請高手處理!
[解决办法]
你又没有进行编码处理，建议采用 POST 请求提交表单，这样比较好解决。
在 Action 中需要转码
String data = new String(input.getData().getBytes( "iso-8859-1 "), "big5 ");
建议配置一个过滤器，否则的话比较麻烦。
若是采用缺省的 GET 请求的话，需要改 URI 编码（改 Tomcat 的 server.xml）、提交时的字符编码，还且在接收参数时还要解码，挺烦的。
