Error loading custom component on 11g- Log4JLogger does not implement Log

user12302540Jun 18 2013

Hello experts,

I am migrating 10GR UCM running on Windows onto 11g Linux/WLS environment. The WLS and the WCC components start good but when I enable a custom component, the UCM application fails to start. This component uses Log4J Logger along with commons-logging

Looks like it’s more of the class loader issue and conflict of Log4J on server/application Jars. I tried all troubleshooting steps but no luck. I have placed all the jars and property files (log4j-1.2.14.jar, commons-logging-1.1.1.jar, wllog4j.jar, log4j.properties, commons-logging.properties) under domain/lib to be picked up on the classpath. Also I compiled the custom component with new Idcserver.jar and commons-logging-1.1.1.jar.

Any help would be greatly appreciated!

Here's the error stack from the server:

provides checkoutandopeninnative:11gR1-1.0.0 feature(s)

'DynamicConverter' component, version '2012_07_20 (rev 23659) 11.1.6.13', provides DCFilterCallbacks:2.0 feature(s)
