Hi,
In my application, I have 2 processes running and there are 3 webapps war files
which get deployed in tomcat version 9.0.60. Out of these 3 war files, one war
file is internal to my application while other 2 are coming as final artifacts
from artifiactory.
My war uses a custom logger and custom ContextSelector, however other 2 wars
from artifactory uses standard logger and standard ContextSelector.
I have defined below system property as a static block in custom logger,
however for some unknown reason when my war gets deployed this log4j jars don't
find this property and leads to ClassCastException
"java.lang.ClassCastException:
org.apache.logging.log4j.core.selector.ContextSelector cannot be cast to
logger.log4j2.CustomLog4j2ContextSelector". To fix this I have placed
'log4j2.component.properties' file on log4j jars class path, but with this fix,
following harmless error get logged for other 2 wars
"java.lang.ClassCastException: Cannot cast
logger.log4j2.CustomLog4j2ContextSelector to
org.apache.logging.log4j.core.selector.ContextSelector".
I am looking for help to come up with a solution where, when my war gets
deployed then custom logger context "logger.log4j2.CustomLog4j2ContextSelector"
should be used while when other 2 wars get deployed then
"org.apache.logging.log4j.core.selector.ContextSelector" should be used. Please
let me know if you have any idea on this.
static {
System.setProperty("Log4jContextSelector",
"logger.log4j2.CustomLog4j2ContextSelector");
}
Content of file 'log4j2.component.properties' ->
Log4jContextSelector=logger.log4j2.CustomLog4j2ContextSelector
