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.

我正在使用struts-1.2.9.jar，common-io-1.3.2.jar和common-file-upload-1.2.1.jar
我甚至没有为控制器编写代码。只是用jsp，我得到了那个错误。任何帮助将不胜感激。
