ConnectException when using <consolePlugin/>
by Paul Nyheim 18 Nov '08

18 Nov '08

Hi. For my JUnit tests, I have configured a logback-test.xml file with only a <consolePlugin/> entry. (debug=false) However, when I run the tests on the build-server, I get the following printed to System.out: 09:02:23,596 |-ERROR in ch.qos.logback.classic.net.SocketAppender[null] - Could not connect to remote logback server at [localhost]. We will try again later. java.net.ConnectException: Connection refused: connect at java.net.ConnectException: Connection refused: connect at at java.net.PlainSocketImpl.socketConnect(Native Method) at at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) I realize that this message is part of logbacks internal status, however it would be nice to have the option to disable this message which pollutes the build-log on the build-server. Maybe by specifying an attribute like this: <consolePlugin silent="true"/> where the underlying Socketappender will be silent if it is not able to connect to the host and port. Regards, Paul Nyheim

DynamicClassLoadingException - How does class loading in logback works?
by Jenny 13 Nov '08

13 Nov '08

Hi, I'm sorry for the earlier posts, my keyboard enter key was malfunctioning. I'm using weblogic 10, and deployed my application as EAR. My custom appender is located in the WEB-INF/lib. I am getting this ClassNotFoundException. app.ear - web1.war - WEB-INF/lib customAppenderPackage.jar So I've tried the following but still it can't find it: - deploying customAppenderPackage.jar as a shared library - putting in APP-INF/lib/customAppenderPackage.jar - adding in the MANIFEST Class-Path - adding as "library-ref" in weblogic.xml and weblogic-application.xml The only one that worked is when I moved the customAppenderPackage.jar in my weblogic server domain library directory. But I don't want this... I want it to be inside my EAR package. Any ideas how to solve this? How does class loading in logback works? Caused by: ch.qos.logback.core.util.DynamicClassLoadingException: Failed to instantiate type com.mycompany.CustomeAppender at at ch.qos.logback.core.util.OptionHelper.instantiateByClassName(OptionHelper.java:45) at at ch.qos.logback.core.util.OptionHelper.instantiateByClassName(OptionHelper.java:23) at at ch.qos.logback.core.joran.action.AppenderAction.begin(AppenderAction.java:50) at ... 51 common frames omitted Caused by: java.lang.ClassNotFoundException: com.mycompany.CustomeAppender at at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at at java.security.AccessController.doPrivileged(Native Method) at at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at at java.lang.ClassLoader.loadClass(ClassLoader.java:306)

Re: [logback-user] Dropping class package name using
by Silvano Maffeis 13 Nov '08

Hi Ceki Currently I'm setting "1" but I would prefer the package names to be completely removed. I was also somehow expecting that "0" would do the trick. Actually I implemented this myself into logback 0.9.9 but I did it in a hacky manner. Good to know that this will be supported in 0.9.12, thanks! Regards, Silvano

How do I get a list of configured loggers?
by Gunnar Hillert 12 Nov '08

12 Nov '08

How do I get a list of configured loggers (In logback.xml) programmatically? e.g. I have the following loggers configured in my logback.xml file: ... <logger name="org.springframework.security"> <level value="DEBUG"/> </logger> <logger name="org.apache.struts"> <level value="INFO"/> </logger> ... How do I get those loggers? (E.g. I like to dynamically inspect and change my setup loggers at runtime) I was able to do this easily in Log4J but I seem to have issues doing so in logback. I thought I could do: LoggerContext lc = ((ch.qos.logback.classic.Logger)LOGGER).getLoggerContext(); List<String> strList = new ArrayList<String>(); Iterator<ch.qos.logback.classic.Logger> it = lc.getLoggerList().iterator(); while(it.hasNext()) { Logger log = it.next(); strList.add(log.getName()); } But this basically adds hundreds of loggers but I only want the ones I have configured in my logback.xml file. What do I miss here? Thanks a lot!

Dropping class package name using PatternLayout
by Silvano Maffeis 12 Nov '08

12 Nov '08

Hi. Is it possible to completely remove the Java package name of a logged class using PatternLayout? Meaning, instead of something like 13:09:30 [main] DEBUG c.q.logback.demo.ContextListener - Classload hashcode is 13995234 I would simply like to see 13:09:30 [main] DEBUG ContextListener - Classload hashcode is 13995234 Regards, Silvano

Appender and zipping file
by Greg Flex 12 Nov '08

12 Nov '08

Hi Guys, I'm using the RollingOverAppender with the TimeBasedRollingPolicy that also automatically zips the file. However when running it for, say, 24 hours with rolling policy of one hour only 23 files get zipped. The same applies if rolling policy is set to a minute; the last file never gets zipped. Anyway I just want to find out if there is a way to tell the RollingoverAppender that the very last file also needs to be zipped even if the full hour hasn't passed yet. Thanks for any info. Greg.

Setting log filename during runtime
by Jenny 07 Nov '08

07 Nov '08

Hello, How can i set the log filename set during the init() of my StartupServlet. I tried using MDC but it's not working for me. What happens is the file is not created. Instead a file with name "%exp{logFileName}" is created on my web server's bin directory. In my StartupServlet, I have this init method that calls MDC.put(). public void init() throws ServletException { MDC.put("logFileName", "c:\\testlogs\\test.log"); Logger log = LoggerFactory.getLogger(StartupServlet.class); log.info("This should be logged"); } In my logback.xml, I have a MDC.get(). <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <append>true</append> <expression name="logFileName">MDC.get("logFileName")</expression> <file>%exp{logFileName}</file> ... I'm new with logback, thanks in advance for your help! I'm trying to follow Ceki's example in his blog http://ceki.blogspot.com/2006/10/repated-configuration-with-joran.html thanks, jenny

Hi there, Has anybody had a chance to look at http://jira.qos.ch/browse/LBCLASSIC-78and http://jira.qos.ch/browse/LBCLASSIC-79 ? They don't seem to be overly complex issues and it would be great to have them fixed in the next logback release. JL

Logback configuration
by Natan Cox 06 Nov '08

06 Nov '08

Hi all, Is there a way to specify the file substitution propery as something configurable? So I would not do <configuration> <substitutionProperty file="variables1.properties" /> but <configuration> <substitutionProperty file="*${logback.properties}*" /> where in Java I would have to specify something like java Main -Dlogback.properties=c:/project/Main/main.properties to be able to run my application? Typically I want to have one configuration file, but sometimes I use multiple files to be able to turn on/off certain functionalities. I'm also thinking of moving the logback properties into my application properties file (not sure yet). This configuration option would allow me to achieve this. Thanks, Natan
