I'm running a program on a WebSphere Liberty 21.0.0.11 with logging from logback 1.2.11. I have a log output folder specified in my server.xml as: <jndiEntry jndiName="logging/logPath" value="${server.output.dir}/logs"/> In the logback.xml I read this entry with the line: <insertFromJNDI env-entry-name="logging/logPath" as="logPath"/> This worked in the old logback versions However in the new version of logback this name is not allowed as the name now must start with "java:". So when I tried to change the line to: <insertFromJNDI env-entry-name="java:comp/env/logging/logPath" as="logPath"/> I get 14:37:59,720 |-ERROR in ch.qos.logback.classic.joran.action.InsertFromJNDIAction - Failed to lookup JNDI env-entry [java:comp/env/stibam/logPath] javax.naming.NamingException: CWNEN1000E: Is there an error in my reading out of that JNDI variable?
