FileUpload in Weblogic Not Working

[Johann]

Something really strange is happening, using the file upload widget/
servlet combination works in hosted mode and in web mode over tomcat
but when I deploy the same in weblogic it sends the request, starts
uploading the file (The servlet is called) but then I get a 404 error,
someone has any idea of what could be the problem?

Thanks,

Johann

Ok, the problem was that a class "org/apache/commons/io/FileCleaner"
was missing but I didn't have the error page that I had specified
inside the web.xml so the 404 error was related to the error page.
