webMethods Log4j2 async disruptor 3.x issue

AnnavaramReddy_S · May 17, 2022, 9:45am

What product/components do you use and which version/fix level?

webMethods Integration Server 10.5

What are trying to achieve? Please describe in detail.

Planning to use the log4j2 async logging , I tried to configure and create the service . But facing the error as mentioned below .

Added the Jar file (disruptor-3.4.2.jar):

Tried adding in Package/packageName/code/jars
and also tried adding in the Integration Server/instances/default/lib/jars but no luck

log4j.xml file :

<?xml version="1.0" encoding="UTF-8"?> {"level":"%p","time":"%d{ISO8601}","thread":"%t","file":"%F","applicationData":%m}%n

<Loggers>
		
	<AsyncLogger additivity="false" level="Info" name="InfoLogger">
			<AppenderRef ref="Log4jDemo"/>
	</AsyncLogger>
	<AsyncLogger additivity="false" level="Error" name="ErrorLogger">
		<AppenderRef ref="Log4jDemo"/>
	</AsyncLogger>
		
</Loggers>

Do you get any error messages? Please provide a full error message screenshot and log file.

You need to move your jar to a sub-folder called static in your package and then restart the IS.
Otherwise the jar is loaded by a private class loader that is only accessible from the package itself.
Hence, why log4j can’t find the factory class.

Hi John,

Thank you for your reply.
I tried by moving the jar file to static folder but getting the same issue.

I can see that the jar file is added to class path as shown in the below screen print . but the issue continue to occur

John_Carter4 · May 17, 2022, 12:32pm

Are there any errors in the log file relating to the jar ?
I checked the jar and it is 1.8 compatible, so that’s okay.
thinking…
Only thing I can think of is to verify the log4j minimum version required by disruptor and check that 10.5 is compliant. Also can you post your log4j.xml file, the above copy is displayed strangely.
regards
John.

Hi Jhon,

Attached the log4j.xml file for your reference

Thank you

John_Carter4 · May 19, 2022, 7:46am

Did you find any related errors in your log files when starting the server?
either
<SAG_HOME>/profiles/IS_default/logs/wrapper.log
<SAG_HOME>/IntegrationServer/instances/default/logs/server.log

Also did you check the log4j minimum version required by disruptor and the version of log4j in wm 10.5 ?

regards,
John.
