-----------------------------
Hi,
I am also hitting the same ClassCastException issue while trying to run the
log4j2 in WebLogic application server. Here is what I have done:
- if I put the api and core jars into DOMAIN_HOME/lib (equivalent to adding the
jars into server classpath) things run okay.
- if I put the api and core jars into
WL_HOME/server/lib/mbeantypes/3rdpartyjars, then this classcast exception is
thrown:
java.lang.ClassCastException:

With code snippet:
import org.apache.logging.log4j.core.LoggerContext;
import org.apache.logging.log4j.LogManager;
...
...
public final class MyAuditProviderImpl implements AuditProvider, AuditChannel{
...
...
public void initialize(ProviderMBean mbean, SecurityServices services){
...
...
LoggerContext ctx = null;
Configuration config = null;
Map mp = null;
ctx = (LoggerContext) LogManager.getContext(false);
mp = config.getAppenders();
System.out.println("***<MyAudit Provider o/p follows> Before logger
re-configuration:");
System.out.println("\tAppenders:" + mp.keySet());
...
...
}
}
- with least hope to solve this issue, I also merged the two jars carefully
(making sure MANIFEST.MF has all the entries) into single one but still same
issue.
Hope this helps in someway to identify what is going wrong.
I am ready to test to collect any additional data for debugging.
Thanks
