[logback-user] Can logging configuration files be separated when using ContextJNDISelector?

[ceki]

Hi Ville,

It has been 3 full years since I've looked at
JNDIBasedContextDiscriminator [1]. Looking at it again it lools like
JNDIBasedContextDiscriminator code supposes that ContextJNDISelector
has been previously installed and that there is only a single
configuraton file for all applications. Have you installed
ContextJNDISelector?

Note that SiftingAppender could propbably fulfill the requirements of
your use case with only a single logback configuration file without
installing ContextJNDISelector. However, for that to work
JNDIBasedContextDiscriminator would need to be (renamed and) modified
to retreive its discriminating value directly from JNDI, something
which is not hard to do.

HTH,
