how to set the logger?

[Gregan, Miroslav]

Hi,
 
I need to use FOP 0.94 embedded, in a big project composed by different 
Eclipse's plug-ins where 2 of them define an org.apache.commons.logging.Log 
library, which causes me the following error:
 
Invalid class loader hierarchy. You have more than one version of 
'org.apache.commons.logging.Log' visible, which is not allowed.

Is there a way how to set the logger manually like it was done before in FOP 
0.20.5 by setting the Driver object?

Thank you.

Miro

More or less the same answer as another thread I just posted a reply  
in...
In short: currently, no. The loggers are static, class-based, and  
cannot be overridden. They are more meant for debug info during  
development.


OTOH, I don't believe we use any specific version of Commons logging,  
so maybe you could try to make FOP use the other version (or make the  
other plugins use the jar that is distributed with FOP) Have you  
already tried removing one version from the classpath?



Cheers
