Log Rotation Fails on Windows if Using JNDI
by Scott Dudley 04 Nov '11

I just discovered that log rotation fails on Windows if using ContextJNDISelector. I've tried both FixedWindowRollingPolicy and TimeBasedRollingPolicy with the same outcome. If I disable JNDI, I lose the contextName but rotation occurs as expected. Here's the error I get: 12:22:36,006 |-INFO in c.q.l.co.rolling.helper.RenameUtil - Renaming file [c:\telmast6\soft\apache-tomcat-6.0.24\logs\debug.log] to [c:\telmast6\soft\apache-tomcat-6.0.24\logs\debug1.log] 12:22:36,006 |-WARN in c.q.l.co.rolling.helper.RenameUtil - Failed to rename file [c:\telmast6\soft\apache-tomcat-6.0.24\logs\debug.log] to [c:\telmast6\soft\apache-tomcat-6.0.24\logs\debug1.log]. 12:22:36,006 |-WARN in c.q.l.co.rolling.helper.RenameUtil - Please consider leaving the [file] option of RollingFileAppender empty. 12:22:36,006 |-WARN in c.q.l.co.rolling.helper.RenameUtil - See also http://logback.qos.ch/codes.html#renamingError And here is my logback.xml file: <configuration scan="true" scanPeriod="30 seconds"> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${catalina.home}/logs/debug.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <fileNamePattern>${catalina.home}/logs/debug%i.log</fileNamePattern> <minIndex>1</minIndex> <maxIndex>5</maxIndex> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <maxFileSize>25MB</maxFileSize> </triggeringPolicy> <encoder> <pattern>%d{MM/dd HH:mm:ss.SSS}|%thread|%X{sessionUserName}|%-5level|%X{debugLevel}|%logger{36}|%replace(%msg){'\n', '~~~'}|%contextName%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="FILE" /> </root> </configuration> The logback and slf4j resources must be loaded by the servlet container classloader (multiple reasons) and this is also desirable as we want to funnel all logging into a single file however, we also need to know which application generated the call - er go our use of JNDI (MDC wouldn't work). By the way, this is a Windows-only issue. Works splendidly on Linux. Thanks. -- Scott Dudley Senior Developer Telesoft Corp. | 1661 E. Camelback Rd., Suite 300 | Phoenix, AZ, 85016

AbstractMethodError in LogbackMDCAdapter
by Raccoonwao 04 Nov '11

04 Nov '11

Hi all, I am using logback 0.9.9 with activemq 5.5.1. Right after startup, the application always encounters an AbstractMethodException in LogbackMDCAdapter, which is firstly triggered by PooledTaskRunner (line 45). A snippet is provided as: public static void main(String[] args) { MDCAdapter l = StaticMDCBinder.SINGLETON.getMDCA(); Map m = l.getCopyOfContextMap(); // <-- got excpetion System.out.println("np error"); // never come to this line } Seems that the concrete class LogbackMDCAdapter implements MDCAdapter without implementing the defined method getCopyOfContextMap(). Any clues? Thanks, Hei

Date instead of timestamp in dbappender
by Jordan Blay 03 Nov '11

Is there a way in dbappender, that timestamp field in logging_event will be a real date instead of int? -- View this message in context: http://old.nabble.com/Date-instead-of-timestamp-in-dbappender-tp32774133p32… Sent from the Logback User mailing list archive at Nabble.com.
