LogLevel controls the amount of information logged. There are 7 log levels:
0 - logging disabled
1 - configuration
2 - severe error
3 - warning
4 - throwing exception
5 - performance
6 - information
7 - debug
The oracle.portal.log.Logger interface defines methods that map to these 7

levels. These methods are included for backwards compatibility and data

Answer 1

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye
