Re: Strange error using code to set up JDBC logger

Hello,

I'm having the same problem and wonder if there is a complete example of 
how to configure a JDBC Appender programmatically.

I'm too getting the exception "Arguments given for element JDBC are 
invalid: field 'connectionSource' has invalid value 'null'".

Thanks
Martin
