Hi,

Since you have already packaged the log4j jar file in your EAR, cloud you
try to use the configuration below :

<sys:import-package>!org.apache.log4j*</sys:import-package>

I seem to have a problem with the class loader due to classes' visibility.
My EAR had references to 3 external application utility jars and 1 reference
to log4j jar.
I deployed the jars and the log4j and then attempted to deploy the EAR. The
deployment complained with NoClassDefFoundError about a class in one of app
jars. I tried to use import-package statements in the plan , but it didn't
help.
So, I packaged all the jars (including the log4j) in the EAR, rebuilt the
EAR , and attempted another deploy.
It now finds my app jars, but still complain about a class in the log4j.
org.apache.log4j.BasicConfigurator: org.apache.log4j.BasicConfigurator
at
org.apache.openejb.assembler.classic.Assembler.createApplication(Assembler.java:835)
<sys:import-package>org.apache.log4j</sys:import-package>
I find v3.x very difficult to work with because of this (or what I believe
to be) OSGi restrictions.
Almost ready to give up and go back to 2.2!
PS I'm using log4j.1.2.14.jar
thanks for any help.
