Subject Re: log4jResource setting in GBean: ApplicationLog4jConfigurationGBean
Date Tue, 09 Jun 2009 08:19:36 GMT

Thanks david.

 I moved folder META-INF/log4j.properties to WEB-INF/classes/, and then
modify deployment plan with :
<dep:attribute
name="log4jResource">META-INF/log4j.properties</dep:attribute>

It works oz it's in the classpath now.
