我有一个rails应用程序,在开发模式下运行(带有sqlite数据库).该应用程序的目的是允许用户通过
Java客户端上载文件.
如果用户想要上传文件夹,则会以递归方式上传其中的所有文件.如果用户想要上传文件,则文件将正常上传.
这是我收到的错误：
IOError
in UploadedFilesController#new
closed stream

我不知道为什么会发生这种情况……客户端会在出现此错误之前上传大约15-30个文件(从文件夹到Java客户端).我正在运行Rails 2.0.2.我是否正在使用sqlite作为数据库在开发模式下运行这一事实？任何帮助将不胜感激 ！
多谢你们 ！
