All, I'm pleased to share my unpolished hslogger4j library, available now from the project homepage[1] or HackageDB. "Hslogger4j provides handlers for hslogger (John Goerzen's Haskell logging framework) that are compatible with log4j's XMLLayout. In particular log messages created by the handlers can be published directly to the GUI-based log viewer Chainsaw v2." The motivation behind the library is to leverage tools developed for the widely used Apache logging framework log4j. In my case I've been monitoring my hslogger[2] logs in real time using the GUI-based Log viewer Chainsaw v2[3]. The library also includes some optional supporting Java files (most importantly a jar) necessary to use Chainsaw with the richer hslogger levels. The README should clarify usage. Thank you, Bjorn Buckwalter [1] http://hslogger4j.googlecode.com [2] http://software.complete.org/hslogger [3] http://logging.apache.org/chainsaw
