Struts2无法上传Word文件，加上application/msword还是不行

Struts2无法上传Word文件 网上粗略的搜了下 加上application/msword还是不行



<action name="UploadAction_*" class="action.UploadAction"

			method="{1}">

			 <interceptor-ref name="fileUpload">

                  <param name="allowedTypes">

                    image/jpg,application/msword

                  </param>

                </interceptor-ref>

		</action>

这里是上传


public String uploadEssays() {

		System.out.println("upaction uploadEssays%%%%%%%%%%%%%%%%%%%%%%%%%%");

		ServletContext sc = ServletActionContext.getServletContext();

		String path = sc.getRealPath("/files/");

		System.out.println(path+"%%%%%%%%%%%%%%%%%%");

		try {

			for (int i = 0; i < file.length; i++) {

				

				//realname

				System.out.println("-----" + file[i].getName());

				System.out.println("-----" + fileFileName[i]);

				String essayname=fileFileName[i];	

				

				// use dateString as save filename

				String dateString = new Date().getTime() + "";

				String filename =  dateString+".doc";



				InputStream in = new FileInputStream(file[i]);

				OutputStream out = new FileOutputStream(path+"/"+filename);

				int len = -1;

				byte[] b = new byte[1024];

				while ((len = in.read(b)) != -1) {

					out.write(b, 0, len);

					out.flush();

				}

				in.close();

				out.close();

				

				saveEssay(essayname, filename);

				

			}

		} catch (Exception e) {

			e.printStackTrace();

		}

		return "toListEssays";

	}


如果上传WORD就会出现这样的错误

严重: Could not find a Content-Type for file. Verify that a valid file was submitted.

先把：
<param name="allowedTypes">
image/jpg,application/msword
</param>


砍了 不限制 上传文件类型 看是否能正常上传

然后在缩小范围

如果是word，
java.lang.NullPointerException
at action.UploadAction.uploadEssays(UploadAction.java:141)
也就是这句话
for (int i = 0; i < file.length; i++) {

file是空的
会是页面上的错误么？
页面是这样写的
<form name="uploadForm" action="UploadAction_uploadEssays.action"
method="post" enctype="multipart/form-data">

<input type="file" name="file" />
