Unable to use SLF4j's MDC with logback 0.9.7.
by Pascal Jacob 16 Sep '07

16 Sep '07

Hello dear logback commiters, I'm trying to use SLF4j MDC in my multithread program and i'm having the following error: SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder". SLF4J: See http://www.slf4j.org/codes.html#no_static_mdc_binder for further details. Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/impl/StaticMDCBinder at org.slf4j.MDC.<clinit>(MDC.java:70) at fr.mipih.jms.AsynchConsumer.<init>(AsynchConsumer.java:50) at fr.mipih.jms.AsynchConsumer.main(AsynchConsumer.java:182) I have the following jars in the classpath : slf4j-api-1.4.2.jar jcl104-over-slf4j-1.4.2.jar logback-classic-0.9.7.jar logback-core-0.9.7.jar I have check the content of the jars and in fact StaticMDCBinder is nowhere to be found (should be in logback-classic-0.9.7.jar as I understand it) I have checked the repository at http://svn.qos.ch/repos/logback/trunk and found that StaticMDCBinder was added in logback-classic\src\main\java\org\slf4j\impl back somewhere in may. I have no [easy] way to compile the new source code on my platform since logback use maven (don't have it, don't want to install it, don't want to learn how to use it). Isn't it time to release a 0.9.8 or something (why not a 1.0) so that slf4j's MDC (and other bug fixes) are available to the majority ? TIA. ZC.

Are there any plans for a logback OSGi bundle in the foreseeable future? ;-)

Re: Time & Size Based RollingPolicy?
by Valeriy Pikulskyy 29 Aug '07

29 Aug '07

Dirk, Wizard's 5th step allows to setup either Size or Time file rolling. Instead I am asking about having both options together: rolling basing on Time & Size (whatever first happens). Ideally I am looking for solution where custom TimeBasedRollingPolicy implementation would allow specifying the custom TriggeringPolicy (e.g. SizeBasedTriggeringPolicy). > > ------------------------------ > > From: dirk ooms <dirk(a)onesparrow.com> > > > Is there any implementation of Time & Size Based RollingPolicy ? > > yes, there is. these options can be selected in step 5 of following wizard: > http://wizardforge.org/pc?action=showVersion&id=72 >

Release of logback 0.9.8
by Ceki Gulcu 22 Aug '07

22 Aug '07

August 22th, 2007 - Release of logback 0.9.8 After several months of gestation, I am happy to announce the immediate availability of logback version 0.9.8. This version of logback synchronizes with SLF4J version 1.4.3. In particular, logback now natively supports SLF4J's MDC API introduced in SLF4J version 1.4.1. If you are using SLF4J version 1.4.1 or later please make sure upgrade to logback version 0.9.8 (or later). Fixed a number of documentation related bugs, in particular bug 90 reported by Luc Maisonobe and bug 88 reported by Sebastian Davids. It is now possible to include configuration file fragments (in XML) as a resource. Previously, it was only possible to include a file by specifying a path to a file or a URL. This feature was requested by Michael Newcomb in bug 89. Fixed caller data extraction problem as reported in bug 78 by Hans van der Meer. The LoggingEvent class' constructor now correctly takes into account the argument array passed by the user. This problem was reported in bug 85 by Robert Christian. You can download logback, including full source code, class files and documentation on our download page, shown below. http://logback.qos.ch/download.html You can receive logback related announcements by subscribing to the logback announce mailing list.

<include> does not search classpath
by Newcomb, Michael-P57487 09 Aug '07

09 Aug '07

Logback searches the classpath for logback.xml or logback-test.xml, but when using <include> there is no way to specify a resource to include (ie something in a jar file) that is on the classpath. <include> is limited to file (explicit file location) or a url (which doesn't allow just a file name). Please add another mechanism for <include> to search the classpath for the file to be included: <include resource="xxx.xml"/> Thanks, Michael

Some strange logback behaviour
by Nicholas Clare 09 Aug '07

09 Aug '07

Hi everyone, I've just switched to using logback for a project, that was using slf4j and jdk logging, but it's gotten a bit big for that. So far logback has been mostly great, except for a couple of small things. However, one major problem has recently come up, and I was hoping someone could help me. I'm using a few rolling file appenders, and everything works fine for a couple of days. However, after that, the current day's log seems to only keep the last line. Every time i 'more' the log, or something, it only has the most recent message, and if i run something like tail -f, it shows one line, and then never updates. The strangest part though, is that when it does eventually roll over, the backed up file (which seems to be called whatever-1970-01-01.log, but that's another issue :P ) seems to be complete. But that doesn't really help when you're trying to debug an issue in a live, running system. Thanks for the great product again, I just hope we can sort this out, so I can keep using it. Nick
