这是smartupload上的例子，代码如下：

<%@ page language="java" import="com.jspsmart.upload.*"%>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload" />

<HTML>
<BODY BGCOLOR="white">


<%

// Variables
int count=0;

// Initialization
mySmartUpload.initialize(pageContext);

// Upload
mySmartUpload.upload();

// Select each file
for (int i=0;i<mySmartUpload.getFiles().getCount();i++){

// Retreive the current file
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i);
//com.jspsmart.upload.Request myRequest = mySmartUpload.getRequest();
// Save it only if this file exists
out.println("Request = " + request.getParameter("temp")+ "<BR>");
if (!myFile.isMissing()) {

// Save the files with its original names in a virtual path of the web server

// myFile.saveAs("/upload/" + myFile.getFileName(), mySmartUpload.SAVE_VIRTUAL);

// sample with a physical path
// myFile.saveAs("c:\\temp\\" + myFile.getFileName(), mySmartUpload.SAVE_PHYSICAL);

// Display the properties of the current file

out.println("FieldName = " + myFile.getFieldName() + "<BR>");
out.println("Size = " + myFile.getSize() + "<BR>");
out.println("FileName = " + myFile.getFileName() + "<BR>");
out.println("FileExt = " + myFile.getFileExt() + "<BR>");
out.println("FilePathName = " + myFile.getFilePathName() + "<BR>");
out.println("ContentType = " + myFile.getContentType() + "<BR>");
out.println("ContentDisp = " + myFile.getContentDisp() + "<BR>");
out.println("TypeMIME = " + myFile.getTypeMIME() + "<BR>");
out.println("SubTypeMIME = " + myFile.getSubTypeMIME() + "<BR>");
myFile.saveAs("/home/web/www/test01/" + myFile.getFileName());
count ++;

}

}

// Display the number of files which could be uploaded
out.println("<BR>" + mySmartUpload.getFiles().getCount() + " files could be uploaded.<BR>");

// Display the number of files uploaded
out.println(count + " file(s) uploaded.");

你的代码！
SmartUpload File can't be saved (1120）
SmartUpload File can't be saved (1120） 上传文件重命名，文件保存出错。。请各位大虾指点啊。。
SmartUpload,jsp重命名上传的文件提示文件无法保存（File can't be saved (1120).）解决思路
SmartUpload smart = new SmartUpload() ; smart.initialize(pageContext) ; // 初始化上传操作 smart.upload() ; // 上传准备 String name = smart.getRequest().getParameter("uname") ; smart.save("/upload"); // 文件保
jspsmartupload上传出现com.jspsmart.upload.SmartUploadException: File can't be saved (1120).
出现这个错误的原因可能是自己访问地址的ip有问题 输出你的ip地址看看是不是0.0.0.0.0.0.0.1这个是ipv6表示的本机地址对应的ipv4就是127.0.0.1. 这个地址在重命名文件的时候会出现错误所以我们可以将其改成其他的ip地址 可以尝试换成自己局域网的ip地址或是自己的本机的ip地址即路径 不再是http://localhost:8080/myupload/myuploa
The file cannot be saved and it may beprotected. 共享文件没有写入权限问题解决
背景 通过samba共享的ubuntu文件，在WINDOWS端打开后无法写入。 查看文件权限 原文件的权限是644 更改为 664后还是不能写入；再次更改为 666生效。 至此，让我们先暂时仔细总结下文件的权限问题，之前都是三七二十一，chmod 777 file.txt。 参考 1. 文件权限 2. linux系统的用户和用户组 3. 文件权限的划分 从结果来看，通过samba共享ubuntu中的文件，此时的身份是其他用户。 有一个问题是我当时配置samba共享时选择的是~/share目录，该目录下tou
