I've done Spring and log4j within an .aar file. I've also got multiple
.aars running independently with their own log4j and Spring setups.
Things I had to do were:
1. Make sure log4j.jar is not in the axis2/WEB-INF/lib folder.
2. Set the axis 2 logger to non log4j logging and remove the axis2
log4j.properties from the axis2/WEB-INF/classes folder.
3. I configure log4j in the init method of my skeleton classes, as you
can be sure at that point that the correct classloader is available - I
think the Spring init phase is using a different classloader to the one
you need.
4. If I'm using either Ibatis or Hibernate inside the .aar I have to
explode it to the services folder - otherwise you get resource not
found exceptions for the mapping files.
A snippet from my skeleton init() methods:
Properties props = new Properties();
props.load(
DataHubAuthenticationServiceSkeleton.class.getClassLoader().getResourceAsStream(
"log4j.properties"));
PropertyConfigurator.configure( props);

This link has details about Axis2 class loading behaviour.

Hi
Eric,
In your code, Spring ClassPathXmlApplicationContext uses a classloader
taken from service.getClassLoader() but log4j doesn't.
Try the same classloader given to Spring for the log4j,
ClassLoader classLoader =
service.getClassLoader();
URL url = "" style="font-weight: bold;">classLoader.getResource("config_ws/log4j.xml");
Hope this helps.

Hi Upul,
Thanks for responding. The below is correct.My .aar looks like the
following:
.aar
|_com
|_config_ws
| |_applicationContext.xml
| |_log4j.xml
|_META-INF
The below code for my springinit.java works fine for the loading the
applicationContext, but I think that axis has a problem with loading the
log4j as it can't recognize the directory structure in the aar. Is
there a
similar call to the getSystemResource that can locate within the
classpath?
thanks,
Eric
