Ok, thanks to all the +1's. I've just started preparing for the change, and started off by thinking about the Test cases first.
Am I correct in thinking that the following is the process to add a test case for log4j & MDC?: * modify XMLLayoutTestCase, add another test method for MDC. * create an xmlLayout.MDC witness file with the expected text output * add the method name to the suite() That seems logical, so I'll be attempting that first, ensuring that the test fails and then start programming until the test works. cheers, Paul --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
