[ http://jira.qos.ch/browse/LBCLASSIC-120?page=com.atlassian.jira.plugin.syste... ] Pavol Juhos commented on LBCLASSIC-120: --------------------------------------- Unfortunately I was unable to reproduce the error outside of our application. After some restructuring of logging bundles the error went away. Feel free to suspend this issue until someone can reproduce the error in a reliable way.
Joran configuration not working in OSGi environment ---------------------------------------------------
Key: LBCLASSIC-120 URL: http://jira.qos.ch/browse/LBCLASSIC-120 Project: logback-classic Issue Type: Bug Components: joran Affects Versions: 0.9.15 Environment: OSGi Service Platform Release 4 Reporter: Pavol Juhos Assignee: Ceki Gulcu
When running in OSGi environment, JoranConfigurator throws a ClassCastException when trying to parse the Logback XML configuration file. The problem seems to be caused by OSGi-unfriendly JAXP parser discovery mechanism as suggested by Dieter Wimberger in his blog post -- http://wimpi.coalevo.net/2008/04/hack-how-to-use-logback.html "[...] JAXP discovery mechanism assume visibility of the parser through the context ClassLoader of the actual thread, which may cause some troubles." Observed exception stack trace: Failed to auto configure default logger context Reported exception: ch.qos.logback.core.joran.spi.JoranException: Parser configuration error occured at ch.qos.logback.core.joran.event.SaxEventRecorder.recordEvents(SaxEventRecorder.java:63) at ch.qos.logback.core.joran.GenericConfigurator.doConfigure(GenericConfigurator.java:105) at ch.qos.logback.core.joran.GenericConfigurator.doConfigure(GenericConfigurator.java:76) at ch.qos.logback.core.joran.GenericConfigurator.doConfigure(GenericConfigurator.java:40) at ch.qos.logback.classic.util.ContextInitializer.configureByResource(ContextInitializer.java:47) at ch.qos.logback.classic.util.ContextInitializer.autoConfig(ContextInitializer.java:108) at org.slf4j.impl.StaticLoggerBinder.init(StaticLoggerBinder.java:85) at org.slf4j.impl.StaticLoggerBinder.<clinit>(StaticLoggerBinder.java:56) at org.slf4j.LoggerFactory.getSingleton(LoggerFactory.java:189) at org.slf4j.LoggerFactory.bind(LoggerFactory.java:112) at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:105) at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:235) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:208) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:221) at com.foo.bar.server.config.Configuration.<clinit>(Configuration.java:244) at com.foo.bar.server.ServerBundleActivator.start(ServerBundleActivator.java:39) at org.apache.felix.framework.util.SecureAction.startActivator(SecureAction.java:589) at org.apache.felix.framework.Felix._startBundle(Felix.java:1671) at org.apache.felix.framework.Felix.startBundle(Felix.java:1588) at org.apache.felix.framework.Felix.setFrameworkStartLevel(Felix.java:1180) at org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:265) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.ClassCastException: org.apache.xerces.jaxp.SAXParserFactoryImpl at javax.xml.parsers.SAXParserFactory.newInstance(Unknown Source) at ch.qos.logback.core.joran.event.SaxEventRecorder.recordEvents(SaxEventRecorder.java:56) ... 21 more
