Just following up on something Mark has mentioned offline re: adding some more support for MDC through XMLLayout, and Chainsaw. I wanted to run some things by the group. Sorry if this is a bit long.
The first thing that needs to happen is to modify the log4j.dtd file to incorporate the MDC structure info. I'm no XML expert, but here's my first guess at an example format : <log4j:MDC> <MDC key="MyKey1" value="MyValue2"/> <MDC key="MyKey2" value="MyValue2"/> ....... </log4j:MDC> If anyone has any comments, speak up now! :) After we're set on the format, it'll be (as Mark said) a snap to modify XMLLayout to include MDC, and then I think just a fraction more effort to modify Chainsaw's XMLFileHandler to digest(!) the MDC info back from XML into something Chainsaw handles. Lastly, the PatternParser class needs to provide a format for outputing ALL the MDC key/value pairs if no extra %X option is added. Now, since the MDC is basically a Hashtable, would anyone object to the format of the output via the PatternParser being just the Hashtable.toString()?. cheers, Paul Smith --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
