I had the same problem and I think I know why J Solaris does interrupt IO blocked thread which then causes the OutputStreamAppender to catch the IOException in line 218 (version 0.9.24). I actually run version 0.9.18 but this part has not change so I guess it will behave the same way. If we look at http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4385444 InterruptedIOException should not be required by platform specification (sol) And log4j https://issues.apache.org/bugzilla/show_bug.cgi?id=44157 InterruptedIOException ignored by log4j I think it should be solved the same why } catch (InterruptedIOException iioe){ //give the thread a changes to act on interruption and then carry on Thread.currentThread().interrupt(); } catch (IOException ioe) { // as soon as an exception occurs, move to non-started state // and add a single ErrorStatus to the SM. this.started = false; addStatus(new ErrorStatus("IO failure in appender", this, ioe)); } I could not find the jira entry mentioned in this thread therefore I write it here J BTY the jvm option -XX:-UseVMInterruptibleIO does prevent the interruption by solaris but that's only a workaround and not solving the problem ;) Cheers Andy

hi all, i have migrated to logback to be able to change the log levels dynamically. i'm testing it now with calssfish 3.01 and somehow it is not working when i change the levels in logback.xml there nothing happens. by deploying from netbeans i get the following: |-INFO in ch.qos.logback.classic.turbo.ReconfigureOnChangeFilter@11bfee0 - Will scan for changes in [[C:\Dokumente und Einstellungen\user_Home\Eigene Dateien\NetBeansProjects\WS-LDAP\build\web\WEB-INF\classes\logback.xml]] every 15 seconds. but when i change the levels in this file nothing happens Any help will be appreciated Hugirat -- إِنَّ الَّذِينَ يُحِبُّونَ أَنْ تَشِيعَ الْفَاحِشَةُ فِي الَّذِينَ آمَنُوا لَهُمْ عَذَابٌ أَلِيمٌ فِي الدُّنْيَا وَالآخِرَةِ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لا تَعْلَمُونَ My public key please use it when you contact me: هذا مفتاحي العام الرجاء أستخدامه عند الإتصال بي: 09BA B710 4B98 ECDA 8C0A 6CB1 2E1E CF88 6A12 F2C3

Class not found exception for LoggingEventVO
by MDerr＠nycm.com 13 Jan '12

13 Jan '12

I have an application client set up to send a logging message over a bus using a logback JMSQueueAppender. Logback version is 0.9.24 and slf4j version is 1.6.1. This is running on a Websphere 7.0 server in Rational Application Developer 7.5. I've tested the bus and queue with a simple text message using the RAD Universal Test Client and that works fine, so at least the foundation is solid. When I log a message to the message queue, I wind up with the following stack trace under a wide variety of attempts: [8/11/10 14:44:16:223 EDT] 0000002b SystemOut O Exception CWSIA0122E: An exception occurred deserializing a message, exception: java.lang.ClassNotFoundException: ch.qos.logback.classic.spi.LoggingEventVO.

use of java.io.File in logback / Android
by Robert Schmid 08 Jul '11

08 Jul '11

I am about to implement an appender that I can use on Android. I'm guessing it won't be much more difficult than doing the same from log4j. The primary problem is that we can't really use java.io.File to access the file system. Android has its own File access API. I believe that this will be as simple as extending RollingFileAppender and overriding methods as needed to swap out the File access apis. Can anybody spot the flaw in my thinking? Are there other pitfalls I need to worry about?

using logback in an API w/o impacting other applications
by Richard Sand 07 Jun '11

07 Jun '11

Hi all, In an API I had to write for a client to interface with an COTS application, I used log4j to bridge to the COTS application's log capability. To totally isolate the usage of log4j in the API I created a wrapper around a Logger with its own Hierarchy. I'm wondering if there is an analogous mechanism for accomplishing this in logback. public final class AgentLogger { public static Hierarchy heirarchy = new Hierarchy(new RootLogger(Level.TRACE)); private Logger wl = null; /** * Private constructor * * @param name */ private AgentLogger (String name) { wl = heirarchy.getLogger(name); wl.setAdditivity(false); } Any advice appreciated. Thanks!

Why DEBUG by default?
by Leonid Ilyevsky 29 Apr '11

29 Apr '11

When logback cannot find configuration file anywhere, it sets the default to send everything to standard output and the level is set to DEBUG. This creates a big problem in our production environment: super-verbose log that is even difficult to look at. My solution was to create a small wrapper using JoranConfigurator. This works great, and I can do whatever I need. However, here is the downside: my code is no longer ignorant of logback. Previously it was purely slf4j everywhere, but now every class is indirectly dependent on logback stuff (though it is limited to 2 lines in every java file). This defeats the purpose of slf4j as pure facade. Is there any better solution? Our problem is, we need to guarantee that no matter what happens in the logging layer, it should never go wild and produce all that debugging noise. ________________________________ This email, along with any attachments, is confidential and may be legally privileged or otherwise protected from disclosure.

DBAppender arguments
by Alphy 29 Apr '11

29 Apr '11

I am using DBAppender with Postgre as my DB. I created few fields arg0,arg1,arg2,arg3...arg8 to store my arguments separately in each fields. But I realised only arg0 .. arg3 is filled with argument values. But the arguments are added in formatted_message field. I looked into the code and realised only 4 fields are used for storing arguments and maximum length is 254. Is it possible to add more arguments and increase the max size . -- View this message in context: http://old.nabble.com/DBAppender-arguments-tp31502308p31502308.html Sent from the Logback User mailing list archive at Nabble.com.

Logback JMX Operations and Attributes
by LogbackUser 28 Apr '11

28 Apr '11

I am using glassfish 3.1 as my application server and I have enabled JMX by adding the <jmxConfigurator/> tag in the logback.xml. I am able to view the logback classic mbeans on jconsole but invoking operations like getLoggerLevel fails with an error - "Problem invoking getLoggerLevel : java.lang.IllegalStateException: WEB9031: WebappClassLoader unable to load resource[java.lang.Object], because it has not been started or was always stop...." Accessing the "LoggerList" attribute also does not give any output. Statuses attributes shows the status messages though. Is there anything I am missing in terms of configuration? -- View this message in context: http://old.nabble.com/Logback-JMX-Operations-and-Attributes-tp31423995p3142… Sent from the Logback User mailing list archive at Nabble.com.
