Action 

@Action(value="plupUploaduploads")
        public String upload() throws Exception {
                isMultipart = ServletFileUpload.isMultipartContent(getReq());
                System.out.println(getReq().getParameter("value"));
                ServletContext servletContext = getReq().getServletContext();
                String filePath = servletContext.getRealPath("/");
                System.out.println(filePath);
                System.out.println(this.file);
                System.out.println(this.fileName);
                System.out.println(this.contentType);
                File theFile = new File("c:\\",this.getFileName());  
                FileUtils.copyFile(file,theFile); 
        return SUCCESS;
    }

//getters and setters

i can see this on console according to print statements given.

o_17oq47949abc11n51pg11rnah06a.jpg
E:\Documents and Settings\Pluto\My Documents\NetBeansProjects\ShareApp\build\web\
c:\temp\upload__408094b5_13e30976641__7fea_00000003.tmp
null
null

is it the problem in my struts config? I am using annotations hence dont have struts.xml file. Or the problem is in plupload sending the file name, because when i retrived the name parameter i am getting some different name "o_17oq47949abc11n51pg11rnah06a.jpg" which is not the actual name. If so how can i get the original name?

Thanks and regards

我仍然不明白你为什么要使用所有这些插件来执行如此简单的操作。你需要AJAX upload吗？如果没有，您可以简单地使用<s:file /> 将一个或多个文件上传到 Action，并自动filesize检查filename和contenttype检测，只需在您的 Action 中声明三个具有相同前缀的变量：

动作代码：

private File fileUpload;
private String fileUploadContentType;
private String fileUploadFileName;
/* getters and setters */

JSP代码：

<s:file name="fileUpload" />

然后，您可以执行客户端（HTML5，使用 javascript）文件大小检查、服务器端文件大小检查，并设置服务器端整体多部分请求大小（在 Struts.xml 中，即使使用注释也应该具有）。

您可以在此处阅读详细信息：struts2 s:form 元素修剪 action 属性中的 s:url 参数

作为最后的建议：做一些简单的工作，然后开始定制/扩展它。

Solution:

Add fileupload interceoptor in struts.xml (< interceptor-ref name="fileUpload" />)

Add the following properties in the action class.

    private String[] fileFileName;

    private String[] fileContentType;

    private File[] file;

现在解决了。我设置unique_names : false了plupload选项。内容类型和文件名null在 struts 动作中。我使用getParameter("name");.
