logback.xml not working inside Ant task
by cowwoc 28 Aug '08

28 Aug '08

Hi, I've got a library that uses Logback through slf4j. When I invoke methods directly logging works just fine, but when I invoke Ant tasks that, in turn, invoke those methods logback.xml isn't being found and the default configuration is being used. I am at a loss as to what is different between the two configurations. When I run under Ant getClass().getResourceAsStream("/logback.xml") finds the file just fine, yet LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); StatusPrinter.print(lc); prints out: 05:08:51,098 |-INFO in ch.qos.logback.classic.BasicConfigurator@5b8ff6b8 - Setting up default configuration. How do I debug this problem further in order to figure out what is going wrong?

Different Log Levels For Different Appenders?
by Eric Faden 28 Aug '08

28 Aug '08

So suppose I set my root logger to error, but I want to have another logger operate at debug level. When I do that it makes that loggers level debug for all appenders. For example take the following <configuration> <appender name="*FILE*" .... </appender> <appender name="*STDOUT*" ... </appender> <logger name="mylogger"> <level value="debug" /> ** <appender-ref ref="FILE" />** </logger> <root> <level value="error" />* <appender-ref ref="STDOUT" />* </root> </configuration> In this example mylogger would output at debug level to BOTH STDOUT and FILE. Is it possible to only get mylogger to output at debug level to FILE and error to STDOUT? I realize that I can add a filter to the STDOUT appender to filter anything below ERROR, but I was curious if there was another way to do this, possibly cleaner? -Eric

Hi, I use this declaration in logback.xml with resin 3.1.6, logback 0.9.9, and slf4j 1.5.2 <configuration> <appender name="email" class="ch.qos.logback.classic.net.SMTPAppender"> <Subject>Error on Application</Subject> <SMTPHost>localhost</SMTPHost> <To>error(a)pippo.it</To> <From>error(a)pippo.it</From> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%ex</pattern> </layout> </appender> <root> <level value="error"/> <appender-ref ref="email"/> </root> </configuration> The emails for errors works but there are two problem : 1) In the Subject with my description is present all error message from stacktrace like this Subject : Error on Application java.lang.NullPointerException at it.dnshst.action.log.LoginAction.doAction(LoginAction.java:74) at it.dnshst.action.BaseAction.runAction(BaseAction.java:221) .....

Re: [logback-user] Why LGPL instead of Apache License?
by cowwoc 23 Aug '08

Ceki, What is the legal implication of using Logback through slf4j? Does this limit our obligations to slf4j's MIT license or does any aspect of logback's LGPL license pass through?

maven and logback
by Rusty Wright 20 Aug '08

20 Aug '08

Maven newbie here trying to convert my Eclipse project to Maven. I tried using the "version 99" of Commons Logging as documented here (so that I can use logback and slf4j instead): http://day-to-day-stuff.blogspot.com/2007/07/no-more-commons-logging.html which was just recently referenced on the logback mailing list. My pom.xml file starts out as below. Below that are the errors. So I don't understand why it's not working. And additionally in the errors part the initial "Downloading:" lines seem odd to me since they have the zapto url prepended to them. Help! Here's the top of the pom.xml file: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd" > <modelVersion>4.0.0</modelVersion> <groupId>people_locator</groupId> <artifactId>people_locator</artifactId> <packaging>war</packaging> <name>People Locator</name> <version>0.0.1-SNAPSHOT</version> <description /> <repositories> <repository> <id>Version99</id> <name>Version 99 Does Not Exist Maven repository</name> <layout>default</layout> <url>http://no-commons-logging.zapto.org/mvn2</url> </repository> </repositories> <dependencies>  <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>99.0-does-not-exist</version> </dependency>  <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging-api</artifactId> <version>99.0-does-not-exist</version> </dependency>  <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl104-over-slf4j</artifactId> <version>1.4.2</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>log4j-over-slf4j</artifactId> <version>1.5.2</version> </dependency>  <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.4.2</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>0.9.9</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.5</version> </dependency> (rest omitted) Here are the errors I get from doing a maven compile (in eclipse): [INFO] Scanning for projects...

jcl-over-slf4 and hibernate3-maven-plugin bug
by Jonathan Dray 19 Aug '08

19 Aug '08

Hi, all I'm experiencing a FATAL ERROR message while trying to build my project with Maven. I'm using Appfuse 2.0.2 that comes with hibernate3-maven-plugin in version 2.1. By default, this plugin uses Apache commons-logging framework. I reported the bug, using hibernate plugin tracking software, and I'll find all the details there : http://jira.codehaus.org/browse/MHIBERNATE-81 Did someone get the same issue and already found a workaround or a patch ? Thank you Regards, Jonathan Dray

Logback Console Plugin - multiple loggers
by Peremský Jan 19 Aug '08

19 Aug '08

Hi, I'd like to use the logback console plugin to "harvest" log events from multiple loggers running on my localhost each logging into different log file. Every logger is configured with <consolePlugin /> as such using default port 4321. Logback View is cofigured to listen at this port too. The problem is: the Logback View displays some log events, but it is never sure from which logger and if any. Did I misunderstood the purpose of the Logback View? Is it only single input capable? Thx Jan

file appender help needed
by Chris Cheshire 18 Aug '08

18 Aug '08

I want to configure logback such that logs are written to the directory logs/yyyy/MM/dd/immigrator.log with the directory structure created each day. I have : <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>logs/%d{yyyy/MM/dd/}immigrator.log</FileNamePattern> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%-25(%date{HH:mm:ss.SSS} [%thread]) %-5level %logger{10} - %msg%n</Pattern> </layout> </appender> The first time the app is run, I see the following : 14:34:13,536 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Adding parent to RollingPolicy: FILE 14:34:13,543 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 14:34:13,544 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern logs/%d{yyyy/MM/dd/}immigrator.log for the active file 14:34:13,557 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - The date pattern is 'yyyy/MM/dd/' from file name pattern 'logs/%d{yyyy/MM/dd/}immigrator.log'. 14:34:13,557 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Roll-over at midnight. 14:34:13,563 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Generated a new name for RollingFileAppender: logs/2008/08/12/immigrator.log 14:34:13,563 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE] - Active log file name: logs/2008/08/12/immigrator.log 14:34:13,564 |-ERROR in ch.qos.logback.core.rolling.RollingFileAppender[FILE] - setFile(logs/2008/08/12/immigrator.log,true) call failed. java.io.FileNotFoundException: logs/2008/08/12/immigrator.log (No such file or directory) java.io.FileNotFoundException: logs/2008/08/12/immigrator.log (No such file or directory) at java.io.FileOutputStream.openAppend(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:177) at java.io.FileOutputStream.<init>(FileOutputStream.java:102) at ch.qos.logback.core.FileAppender.setFile(FileAppender.java:142) at ch.qos.logback.core.FileAppender.start(FileAppender.java:99) at ch.qos.logback.core.rolling.RollingFileAppender.start(RollingFileAppender.java:57) (stack trace truncated for brevity). This creates the directory structure properly, but the initial log file is not created. If I then run the app again, then a log file is created in the date-based directory. If I add a <File>logs/immigrator.log</File> element to the appender, then it creates the log file outside of the date structure and only rolls it at the end of the day. This is not what I want. I want all my log files automatically written to the "logs/yyyy/MM/dd/" directory only, not in a staging area then moved at the end of the day. I tried putting the pattern into the file element but I got a similar exception with logback trying to create the file name exactly as it was specified without expanding the date formats. I looked into using variable substitution but this requires me to set the log directory in the java code itself. I could do this by creating a ${log.dir} system property and having the app create the date based structure before anything else is done, but I don't want to have to do this in every system app I write (this is the route I went with log4j). It would be a lot easier if logback took over this part of things purely in the configuration. Is this possible? Chris

Buffered Appender?
by Eric Faden 18 Aug '08

18 Aug '08

I want the ability to buffer up the last N messages above some level and then release them all if it gets a message above another level. I know you can make a custom appender for Log4j for this, but is it possible in LogBack. As an example.... I have a class A with a function Test()..... Test has a couple Debug messages which I want to get buffered. If Test throws an Error level message I want the appender to dump the Debug messages and then the Error one. Is that possible? -Eric
