Could not access component for hint

[Cristina Ulivi]

Hi all. I've installed Tomcat 4.0.1& Cocoon 2.0.1 on a Windows 2000 o.s. It's all right, but now when I invoke the page "intrasl\flussi\upload.xsp" to upload a file I have the next error: Could not access component for hint: org\apache\cocoon\www\intrasl\flussi\upload_xsp   Someone of you can tell me why, please?   Thank you.   Cris
