multipart / form-data和java.lang.NoClassDefFoundError：java.rmi.server.UID是一个受限制的类 [英] multipart/form-data and java.lang.NoClassDefFoundError: java.rmi.server.UID is a restricted class

问题描述

 < form method =postaction =addBook.do？ reqCode = submitenctype =multipart / form-data> 
< input type =filename =myfile/> 
< / form> 
  

当我提交时，我收到了这个错误

  java.lang.NoClassDefFoundError：java.rmi.server.UID是一个受限制的类。有关更多详细信息，请参阅Google App Engine开发人员指南。

我使用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。就跟jsp一样，我得到了那个错误。任何帮助将不胜感激。

解决方案

我想你的答案在这里： http://code.google.com/appengine/kb/java.html#fileforms

I'm having this jsp page.

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

When I submit, I got this error

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

I'm using struts-1.2.9.jar , common-io-1.3.2.jar and common-file-upload-1.2.1.jar

I didn't even write code for the controller. Just with the jsp, I got that error. Any help will be greatly appreciated.
