No. What we have to do is to re-bundle them with the required 
information. Or may be we can define a property file where you can put 
statr levels externally as well. WDYT?

Up to now the convention was to use the prefix org.wso2.carbon followed 
by the artifact ID. So for axis2 it is org.wso2.carbon.axis2. I guess 
this is same as what spring is doing except for the fact that they are 
using both artifactId and the groupId.

Thanks,
Ruwan
