Re: [logback-user] Logback suddenly stopped logging

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

Class not found exception for LoggingEventVO

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?

JDK14Appender for logback: Anybody written one?
by Thorbjørn Ravn Andersen 18 Apr '11

18 Apr '11

Hi. I have a situation where I have a Java EE 6 web profile application which currently means that it needs to run in Glassfish 3.0.1. The appropriate way to log under Glassfish 3.0.1 is using java.util.logging which works well with slfj4-jdk14-whatever but where the _configuration_ of the logging system inside Glassfish sucks in new and exciting ways, which I have decided not to use. Hence I have figured out that what would work fine for us would be to embed logback in our application, use our usual logback configuration files which filter out those things we dont need anyway, and then let logback just end up dumping the log statements actually to be logged to java.util.logging. In other words, I need a JDK14Appender for logback. Has anyone written such a beast? It is not part of the standard logback distribution L Thanks /Thorbjørn

Are included files scanned
by Rosarin Jolly Roy 12 Feb '11

12 Feb '11

I have a top-level config file logback.xml and another file logback-included.xml. If I set the scan=true in the logback.xml file, will the included file also be scanned for changes? Is scan=true applicable for <included> tag as well? I find that the scanning doesn't happen, when I change the included file. Should I do anything special? --- logback.xml --- <configuration scan="true"> <include file="logback-included.xml" /> </configuration> --- logback-included.xml --- <included scan="true"> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>mylog.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>mylog.log.%d{yyyy-MM-dd}</FileNamePattern> </rollingPolicy> <encoder> <pattern>%date %level [%thread] %logger{15} %msg%n</pattern> </encoder> </appender> <root> <level value="DEBUG" /> <appender-ref ref="FILE" /> </root> </included> _________________________________________________________________ Hotmail has tools for the New Busy.

KnowledgeKnowledgeSession.startProcess() thread safe ?
by TheMax-2 26 Nov '10

26 Nov '10

Hello, I wrote a micro benchmark in order to test the performance of Drools Flow 5.1.0 in single and multi-threaded environments. And I noticed that, when 2 threads call startProcess() at the same time (Intel Core 2 Duo CPU), the returned process instance IDs are the same. I checked the code and it seems there is no locking mechanism in the org.drools.process.instance.impl.DefaultProcessInstanceManager class for the id creation. Is this a bug or am I missing something ? Thanks -- View this message in context: http://old.nabble.com/KnowledgeKnowledgeSession.startProcess%28%29-thread-s… Sent from the Logback User mailing list archive at Nabble.com.

Elongated system startup-time because of Logback configuration
by nikhil diwan 25 Nov '10

25 Nov '10

Hi, I have a startup_batch file in which I make a call to JAVA application which is responsible for starting up my application with SWT window which displays system running information. Issue is the elongated start up time for application, as I executes my batch file, it stops for a while (as if it's doing nothing) though I know that in background batch file is loooking for logback.grrovy or logback.xml file in the classpath then configures it, but meanwhile my SWT window is not even started and I need to wait for around 45-50 Secs whenever I restart my application. As I can't afford delay in application start so I am looking for some workaround to reduce this logback configuration time by my application everytime. Any helps/inputs/thoughts are welcome. ~Thanks Nikhil
