Maybe someone more familiar with JCA will chime in, but as far as JBoss
Logging I don't believe there are any listeners or callbacks. If you're
going to use JBoss Logging you might as well just use a Logger rather
than the ManagedConnection.getLogWriter(). You'd have more control over
the configuration that way.

Hi all,
we implemented a resource adapter which makes use of the PrintWriter
instance injected to
the managed connection factory for error logging/tracing purposes. By
searching for a way to
enable/disable tracing during runtime we found out that the JCA
container of jboss-as-7.1.0.CR1
just injects a System.out printer during deployment time. If I this
isn't right, please correct me.
The JCA (1.5) spec says the following:
"An application server manages the association of a log writer with a
ManagedConnectionFactory. When a ManagedConnectionFactory instance is
created, the log writer is initially null and logging is disabled.
Associating a log
writer with a ManagedConnectionFactory instance enables logging and
tracing
for the ManagedConnectionFactory instance."
This is exactly the behaviour that we would like to have :-)
In our opinion it would be a better idea to write to a specific JBoss
logger rather than to System.out.
I checked out the sources from github and locally tested with a
PrintWriter wrapper subclass which
prints out to a org.jboss.logging.Logger instance if trace is enabled
for that particular logger.
It would be also nice if we could get notified about log level changes
so that we could reset
the ManagedConnection.logWriter back to null if tracing gets disabled.
If so, the log writer could be
null checked within the RA implementation so that the trace code (e.g.
message formatting) doesn't
need to be executed if trace is disabled...
Is there a kind of callback mechanism implemented in jboss logging?
What's your opinion about a suitable solution? Do you have any proposals?
Best regards
Christian
