RE: ErrorHandler problem (was ODBCppender problem)

Having looked through the error handler logic, I'm not surprised that it
has been removed.  The unfortunate part about the implementation is that
it is one-way:  the existing appender(s) were zapped by the fallback
appenders, and no provision existed to recover automatically.  Fixing
this flaw would amount to a generalized fault-tolerance solution, which
tends to be a fair piece of work infrequently used.  As Curt states
below, in the long run it would be easier to build a custom appender
that provides the switchover logic transparently, since this could then
have the necessary triggers to provide recovery, replay, etc., which are
(of course) app-specific.

Cheers!

FallbackErrorHandler and ErrorHandler have been removed from log4j.  I 
had hoped to find a thread discussing the rationale for removing this 
feature, but was unsuccessful.  I believe that recommended alternative 
is to implement a custom Appender that implements your desired 
strategy.
