下面是upload.jsp
<%@ page language="java" contentType="text/html; charset=GBK"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK" />
<title>使用List上传多个文件</title>
<SCRIPT type="text/javascript">
function addComponent()
{
var uploadHTML=document.createElement("<input type='file' name='upload'/>");
document.getElementById("fi").appendChild(uploadHTML);
uploadHTML=document.createElement("<p/>");
document.getElementById("fi").appendChild(uploadHTML);
}
</SCRIPT>
</head>
<body>
<s:fielderror />
<form onsubmit="return true;" action="upload.action" method="post"
enctype="multipart/form-data">
<input type="button" onclick="addComponent();" value="添加文件" />
<span id="fi"> <input type='file' name='upload' />
<p />
</span>
<input type="submit" value="上传" />
</form>
</body>
</html>
下面是UploadAction.java package lee;

import java.util.*;
import java.io.*;
import com.opensymphony.xwork2.ActionSupport;
public class UploadAction extends ActionSupport
{
private String title;
private List<File> upload;
private List<String> uploadContentType;
private List<String> uploadFileName;
private String savePath;
public void setSavePath(String value)
{
this.savePath = value;
}
private String getSavePath() throws Exception
{
return ServletActionContext.getRequest().getRealPath(savePath);
}
public void setTitle(String title) {
this.title = title;
}
public void setUpload(List<File> upload) {
this.upload = upload;
}
public void setUploadContentType(List<String> uploadContentType) {
this.uploadContentType = uploadContentType;
}
public void setUploadFileName(List<String> uploadFileName) {
this.uploadFileName = uploadFileName;
}
public String getTitle() {
return (this.title);
}
public List<File> getUpload() {
return (this.upload);
}
public List<String> getUploadContentType() {
return (this.uploadContentType);
}
public List<String> getUploadFileName() {
return (this.uploadFileName);
}
@Override
public String execute() throws Exception
{
List<File> files = getUpload();
for (int i = 0 ; i < files.size() ; i++)
{
FileOutputStream fos = new FileOutputStream(getSavePath() + "\\" + getUploadFileName().get(i));
FileInputStream fis = new FileInputStream(files.get(i));
byte[] buffer = new byte[1024];
int len = 0;
while ((len = fis.read(buffer)) > 0)
{
fos.write(buffer , 0 , len);
}
}
return SUCCESS;
}
}
下面是struts.xml <?xml version="1.0" encoding="UTF-8"?>

把upLoad属性类型改成File[]试试

不是STRUTS的问题,
是JS不太规范, 改成下面这样就行了 
function addComponent()
{
var uploadHTML=document.createElement("input");
uploadHTML.name="fileList";
uploadHTML.type="file";
document.getElementById("fi").appendChild(uploadHTML);
uploadHTML=document.createElement("br");
document.getElementById("fi").appendChild(uploadHTML);
}

action中属性问题 应该采用数组来接收upload!
