就出现这样的错误
jspsmart\upload\SmartUpload.java:319: '[' expected
byte abyte0[] = new byte;请各位高手解释一下,帮我改一下,谢谢
或者谁已经有可以下载中文名字的方法
给我讲一下,

这样都可以吗?

}去年写的你查考下吧我记得中文名没问题,另外这个不好用,推荐用apache的io
com.util.DownLoadFile dlf = new com.util.DownLoadFile();
dlf.initialize(getServletConfig(),request,response);
dlf.downloadFile(文件);
