[logback-user] Current version of logback can't read my JNDI entry

[Hendrik Stichweh]

Hello Ceki,

thank you for your answer! I tried your examples but no luck. Actually now
I think the error that is given to me mentions that any entry starting with
"java:*" will be not read. The message is in german but I translated it:

ERROR in ch.qos.logback.classic.joran.action.InsertFromJNDIAction - Failed
to lookup JNDI env-entry [java:global/stibam] javax.naming.NamingException:
CWNEN1000E: A JNDI operation for a java:comp/env- Names cannot be executed
because the current thread is not associated with a Java EE (Java
Enterprise Edition) application component. This condition can occur when
the JNDI client using the java:comp/env name is not in the thread of a
server application request. Ensure that a Java EE application does not
perform JNDI operations on java:comp/env names in static code blocks or in
threads created by that application. Such code is not necessarily executed
in a server application request thread and is therefore not supported by
JNDI operations on java:comp/env names.

As a workaround, to not having to use JNDI, I just used the actual filepath
in the logback.xml as:
<File>"${server.output.dir}logs/log-output.log</File>

Which solves the first problem but now logback doesn't seem to be able to
acces the file (if i copy and paste the filepath from the log output
following I can open that file with explorer):. If I start my program I get
the following log output.

23:16:12,543 |-INFO in

I guess this has more to do with my project setup now.
