Um... a couple of questions.. 1. How can we have multiple configuration contexts active in the same JVM if the factory hold the configuration context int a static field?
Why would we need multiple configuration contexts for a single Axis2 instance? 2. DO you intend to deprecate methods such as
MessageContext.getConfigurationContext()?
MessageContext.getConfigurationContext() will return the correct ConfigurationContext. No plans to deprecate it at the moment. David
