Hi, Javier Thank you very much. My problem is that I have hundreds types, and the line of the log file should be populated from the values of the vo fields. So, I want to implement a custom Appender and a Layout, and the Appender could dynamically switch to different log file according to the vo type. So, could you give me some suggestions?
