1.0 release date?
by Ari Meyer 07 Sep '10

07 Sep '10

Hi, We'd like to switch from log4j to logback, but can't use beta releases. logback has been in development for over 4 years now -- any idea when we'll see a 1.0 release? Thanks, Ari

No output received in eclipse plugin
by Joshua White 03 Sep '10

03 Sep '10

Hello, I am using the following: logback eclipse plugin ver 1.1.0 logback 0.9.24 In my log files I receive a message indicating the logback is sending output to port 4321: 11:08:48,791 |-INFO in ch.qos.logback.classic.joran.action.ConsolePluginAction - Sending LoggingEvents to the plugin using port 4321 I don't receive anything in the eclipse plugin which is listening to the same port. I saw an entry on stackoverflow from March indicating that the plugin expected logback version 0.9.9. Is this still an open issue or do I have another problem? Thanks, Joshua

TRACE vs. DEBUG
by oss＠mrab.de 02 Sep '10

02 Sep '10

Hi all, I'm using LOGBack for some months now figured out something strange with the log levels: In the Level class the int values for TRACE and DEBUG are different, but the Integers are both set to the int value of the DEBUG level. The filters in JaninoEventEvaluator use the Integers (which are equal) so "level==DEBUG" matches both DEBUG and TRACE messages. Here is some code from logback-classic (0.9.24) ch.qos.logback.classic.Level: ////////////////////////////////////////////////////////////////// public static final int DEBUG_INT = 10000; public static final int TRACE_INT = 5000; public static final Integer DEBUG_INTEGER = new Integer(DEBUG_INT); public static final Integer TRACE_INTEGER = new Integer(DEBUG_INT); ////////////////////////////////////////////////////////////////// Is that a feature or a copy and paste bug? Any information is appreciated. Cheers, Melchior

bug - Log4j XMLLayout does not encode data
by David Balažic 31 Aug '10

31 Aug '10

Hi! It seems the Log4j XMLLayout * does not properly XML encode data it puts into the output XML. Example: 116 buf.append("\" thread=\""); 117 buf.append(event.getThreadName()); 118 buf.append("\">\r\n"); The thread name can be any string, so it can include characters like <>"/'& etc... That would break the XML. * http://logback.qos.ch/xref/ch/qos/logback/classic/log4j/XMLLayout.html same in the logback 0.9.24 David Balažic Software Engineer ComTrade HERMES SoftLab a ComTrade company HERMES SoftLab d.o.o.

by David Balažic 31 Aug '10

31 Aug '10

Hi! http://logback.qos.ch/manual/appenders.html The properties of DBAppender are not described. What exists besides connectionSource? Is there a way to turn off logging line numbers and other caller data? (performance!) Regards, David Balažic

Multiple JVMs writing to a single log file
by Becker, Thomas 27 Aug '10

27 Aug '10

I had a question about multiple JVMs writing to a single logfile. I'm aware of the "prudent" setting on FileAppender and that its purpose is to allow this. But we have noticed that we are getting the expected behavior without turning prudent mode on. That is, we are seeing the output of both processes interleaved in the single file even with prudent=false. So my question is, are we just getting lucky? Is this due to the platform we're running on (Linux) and will it break on Windows? Honestly we are probably going to switch to logging to separate files per application instance, I was just curious as to why this is working and what would be different ifwe enabled prudent mode.

not finding property file import from WEB-INF/classes/logback.xml
by Dennis Halladay 24 Aug '10

24 Aug '10

I am using logback in a Tomcat 6/Spring application. Most of our property files are under WEB-INF. I am getting the following error trying to import a property file. 11:25:41,110 |-INFO in ch.qos.logback.classic.LoggerContext[default] - Found resource [logback.xml] at [file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat%206.0/we bapps/PharmaServices/WEB-INF/classes/logback.xml] 11:25:41,449 |-INFO in ch.qos.logback.classic.joran.action.ConfigurationAction - debug attribute not set 11:25:41,453 |-ERROR in ch.qos.logback.core.joran.action.PropertyAction - Could not read properties file [../jdbc.properties]. java.io.FileNotFoundException: ..\jdbc.properties (The system cannot find the file specified) logback.xml contains: <configuration> <property file="../jdbc.properties" /> Any suggestions? What happens once I jar up the contents of classes and move to the lib directory? Thanks, -Dennis

smtpappender buffer size
by Chris Cheshire 19 Aug '10

19 Aug '10

I just upgraded from 0.9.17 to 0.9.24 and now my SMTPAppender is dysfunctional. Previously it had a BufferSize option that I had set to 1 so that I could send out a single email per error. Now I get the error and 255 of it's closest debug, info, and warn friends even though the appender is only triggered by error messages. This makes for error emails that are ludicrously long and contain 99% chaff. I need to be able to configure the SMTPAppender to be able to have a buffer size of 1. How do I do this with the latest configuration model? I looked at the docs for the evaluator, and I am unclear if this is what I have to use, and even how to use it. Help! Chris

FileAppender#setBufferedIO
by Lars Fischer 15 Aug '10

15 Aug '10

Hello, I would like to switch from Log4J to Logback. The old system extended Log4J FileAppender and used a method "setBufferedIO". The Logback FileAppender has no such a method. Does it no longer buffer? Regards, Lars
