How to use CustomSQLDBReceiver: 1. create a $userhome/.chainsaw/plugins folder 2. copy your jdbc driver to the plugins folder 3. the Chainsaw downloads page links to an 'inportant distribution notes' link for more info about extended features - go there and follow the instructions for what you're trying to do (db extensions) 4. create a chainsaw xml config file containing a customsqldbreceiver section 4a. make sure to follow the directions in the class javadoc for the receiver for setting up the 'sql' param (read: all fields must be aliased!!) 5. change Chainsaw's 'automatic configuration url' to the URL of the chainsaw xml config file (view-show application wide preferences menu) 7. you may need to check the 'ok to remove security manager' checkbox as well (on the same prefs screen) 8. restart Chainsaw
You should have a receiver defined in the receivers panel. If you don't, you haven't got the URL entered correctly in the application-wide prefs screen, or the chainsaw XML config isn't defining the receiver configuration correctly (see an example of a receiver config on the Welcome tab's 'view example receiver configuration' button). If you can't figure this out, turn on your java console, pre-configuration Chainsaw logging goes there. If you don't get a new tab containing your db's events, examine Chainsaw's own logging in the chainsaw-log tab - it should explain what the problem is. If you still have problems, feel free to email the list.

The receiver essentially requires you to define aliases from your columns to fixed columns the receiver is going to use to run the query. It also supports an IDField param, which is assumed to be an auto-incrementing int, which will allow you to 'tail' the events from the database when running the query multiple times (if the refreshMillis param is defined).
