LoggingEvent's argument array (Object[]) is not populated by constructor nor Logger
by Robert Christian 07 Jul '07

07 Jul '07

Hello, I need access to the logged Object[], which should be populated in the LoggingEvent as argumentArray. Unfortunately (a) Logger does not populate this via the setter method, and (b) the LoggingEvent constructor swallows this. I think this may be a bug. Regards, Rob

Logback Oracle problem.
by Søren Davidsen 23 Jun '07

23 Jun '07

Hi List, I am using logback 0.9.7, and having problems with getting logged into an Oracle database using the DBAppender. I am using c3p0 as a datasource like this, and the tables are created as per the provided .sql files from the distribution: <appender name="DATABASE" class="ch.qos.logback.classic.db.DBAppender"> <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource"> <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource"> <driverClass>oracle.jdbc.OracleDriver</driverClass> <jdbcUrl>jdbc:oracle:thin:@xxx:yy:ZZ</jdbcUrl> <user>ppppp</user> <password>qqqqqq</password> <param name="acquireRetryAttempts" value="1" /> <param name="acquireIncrement" value="1" /> <param name="minPoolSize" value="1" /> <param name="maxPoolSize" value="2" /> <param name="maxConnectionAge" value="600" /> </dataSource> </connectionSource> </appender> It works very sporadic, only some log-statements are put into the database (I have not yet found any pattern in which), and exceptions are never put into logging_event_exceptions Is there something I need to do or something else I'm missing? Thanks, Soren

Q: Howto force flush before exiting
by Jason Buberel 20 Jun '07

20 Jun '07

Here is the behavior I currently observe: I am using an SMTPAppender to delivery logging messages to my Inbox. By default, the SMTPAppender implementation that comes with Logback will trigger the sending of an email (including all accumulated messages) upon receipt of an ERROR level logging message. As a result of the default behavior, you can end up in a situation where you generate 100 INFO level messages to the SMTPAppender and when your application exits, no email will have been sent. Those 100 INFO-level logging messages will be discarded. Here is the behavior I would like to achieve: I would like to implement an EventEvaluator or TriggerPolicy that would force the email to be sent at time of exit or termination. I know that overriding finalize() is not a reliable method of doing this, as there is no guarantee that the VM will actually call it. I did try using hivemodule's Discardable interface in a subclass of SMTPAppender, which I use elsewhere in my application, but ran into problems with class loaders and the like. Any suggestions on the best way to achieve this - guaranteed flush/send of the email message if there are any unsent events in the queue? -jason -- View this message in context: http://www.nabble.com/Q%3A-Howto-force-flush-before-exiting-tf3953809.html#… Sent from the Logback User mailing list archive at Nabble.com.

maven jetty logback
by Kevin S. Clarke 20 Jun '07

20 Jun '07

Hi, I want to use logback with the maven-jetty plugin but I don't seem to be able to find the right place to put the logback.xml file. I've read the jetty app by itself looks in the $JETTY_HOME/resources folder but $project/src/resources doesn't seem to work for the plugin. Any ideas? Thanks, Kevin
