Commons Configuration problems

[jax <ja...@yahoo.com.sg>]

Hi, i am incorporating
org.apache.commons.configuration.* into my code (which
uses java.util.Properties) and i face two problems.

Prob 1:
I have a 

compositeconfiguration.add(new
PropertiesConfiguration("file path"));

which result in the printout of the following non
fatel error, "log4j: Error could not find value for
key log4j.appender.console.layout"

What is this message about? Does it lead to the next
error below?

Prob 2:
I have a 

Iterator itr = compositeconfiguration.getkeys();

which result in the following fatal error,
EMPTY_ORDER_ITERATOR


I have search the web and forums for interpretations
but could not find one, please advice.

Thanks,
jax

This message seems to indicate a problem with your log4j configuration. 
I am quite sure that it is not related to commons configuration.

I haven't seen this before either. Could you please provide your 
complete test code and a full exception trace? Thanks.
