[ http://jira.qos.ch/browse/LBCORE-46?page=com.atlassian.jira.plugin.system.is... ] Ceki Gulcu commented on LBCORE-46: ---------------------------------- Hello Mark, The problem is caused by : java.lang.ClassNotFoundException: com.ziesemer.test.TestAppender As I understand it, the class loader for your WAR is a child of the EAR class loader. However, logback will attempts to use the same class loader that loaded the LoggingContext, i.e. the EAR class laoder, which cannot see com.ziesemer.test.TestAppender in your war file. Placing com.ziesemer.test.TestAppender in the EAR will solve the problem. You should also place logback.xml in the EAR file. The above should work as long as you have only one WAR file in the EAR.
DynamicClassLoadingException trying to use customAppender ---------------------------------------------------------
Key: LBCORE-46 URL: http://jira.qos.ch/browse/LBCORE-46 Project: logback-core Issue Type: Bug Components: Joran Affects Versions: unspecified Environment: Operating System: All Platform: All Reporter: Mark A. Ziesemer Assignee: Logback dev list Attachments: LogBackCNFE.txt
I'm trying to use a custom Appender with Logback under a WebSphere 6.1 application, but am failing upon Logback configuration with a ch.qos.logback.core.util.DynamicClassLoadingException, caused by a java.lang.ClassNotFoundException . A search on this mailing list for "DynamicClassLoadingException" returned 0 results, and neither the documentation nor Google were of any further help. Here's my setup: EAR: - logback-classic-0.9.9.jar - logback-core-0.9.9.jar - slf4j-api-1.5.0.jar - ... WAR (configured to PARENT_LAST): - logback.xml - com.ziesemer.test.TestAppender I will attach the stack trace / STDOUT, as it is a bit lengthy (141 lines).
