Re: Logging with 1.0dev

[Simon Pepping <sp...@leverkruid.nl>]

Will,

I am answering you on fop-user.

See xml-fop/src/private-resources for an example of how to configure
logging with SimpleLog (org.apache.commons.logging.impl.SimpleLog). If
you want to selectively change the log level for some loggers, you
will have to dig in the code for the logger names. Often they are the
package or class name.

Regards, Simon
