hi. this is okay; it is not an error at all. note that these items are being logged at DEBUG level. the config library is checking in a bunch of places for config information, and logging at DEBUG where it has failed to find it. but there are now lots of different places config information can live. not finding it in any one particular place is not a problem. (maybe we shouldn't log the stack trace, because it freaks people out to see stack traces even in DEBUG logs?)

anything that users should consider an error will be logged by c3p0/mchange-commons-java at some level above INFO. logging can be quite verbose at DEBUG log levels. If these messages are bothersome to you, just edit your logging config so that the logger com.mchange.v2.log.MLog logs at INFO and above.

Thanks for the prompt response.

I have turned off the message in log4j in this way:

<logger name="com.mchange.v2">
    <level value="info"/>
</logger>
