Re: [Axis2] DeploymentClassLoader

[Afkham Azeez <af...@gmail.com>]

Log4J is configured at the global level. Hence, you cannot have
different log4j configurations for your services. This is true even
for JavaEE applications deployed on application servers. The
configuration of logger etc. of the different applications has to be
carried out at a global level.
