Log4JLogger does implement Log (in this version at least). Perhaps you
have an older version of commons logging lurking around somewhere in the
classpath?

Subject: Re: Properties instead of config file
Since that subject came up. It would also be nice to pass a URL for
configuration (like in log4j). We had that need in our project and
created a small hack but would be great if that was part of the official
version.

Hi
To set the config filename now on ehas to use
th emethod setConfigFilename on org.apache.jcs.JCS
It would be nice if there would be a second method
on the JCS object which would allow it, to pass a
Properties object instead of a filename. The problem
which occurred in our web application is the following:
we need to parse the cache.ccf and set the paths for
the file-cache on the startup of the servlet container.
in this case we need to write the cache.ccf after setting
the paths to the file cache and pass then the filename
of it with setConfigFilename to JCS. under some circumstances
JCS now can't read the file (maybe it isn't written entirely?)
and JCS gets a NullPointerException:
java.lang.NullPointerException

at org.apache.jcs.JCS.getInstance(JCS.java:103)
So if there's a way to pass the Properties object without writing
it down to disk this would be great.
Maybe we can implement this in JCS, but we're not yet committer to
the JCS project. What do the committers think about it?
