java - multipart/form-data 和 java.lang.NoClassDefFoundError : java. rmi.server.UID 是受限制的类

Question

我有这个 jsp 页面。

<form method="post" action="addBook.do?reqCode=submit" enctype="multipart/form-data">
<input type="file" name="myfile" />
</form>

当我提交时，我收到此错误

java.lang.NoClassDefFoundError: java.rmi.server.UID is a restricted class. Please see the Google  App Engine developer's guide for more details.

at org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:310)
at org.apache.struts.upload.CommonsMultipartRequestHandler.handleRequest(CommonsMultipartRequestHandler.java:193)

我正在使用 struts-1.2.9.jar 、 common-io-1.3.2.jar 和 common-file-upload-1.2.1.jar

我什至没有为 Controller 编写代码。就用jsp，我得到了这个错误。任何帮助将不胜感激。
