In Windows: If you have java 1.4, Java Web Start has it's own menu under start-programs. file-preferences, advanced tab, check 'show java console'. You can also hit the 'clear folder' button from there to remove Chainsaw from your web start cache so it has to be downloaded again.
If you have java 1.5, go to control panel, java. On the 'Advanced' tab, expand the 'java console' link and select 'show console'. To clear your app cache, go to the general tab, then select settings, the 'view applications' button, select 'log4j chainsaw v2' and hit the 'remove selected application' button. MDC is mapped diagnostic context - a way to associate name/value pairs with a thread that are logged with every log event - used for example when you are logging a server-side app and want to associate the user initiating the process with the logging events for that process. search your code for MDC. On Linux, you probably have to find the javaws app and run it, and find the console option and check it.
