The reason why B is not found in A is b/c of the way we deploy deployers/ vs. deploy. ProfileService in AS, deploys different parts of AS libs in different phases. (1) bootstrap phase -- conf/bootstrap/ dir (2) deployers/ (3) deploy/ So, at the time your A class in deployers/a.jar is deployed, B class in deploy/b.jar is not yet deployed, hence no matching classloader. If you would lazy load A, only checking B when you know it's gonna be available, it would be OK. Different sub-systems set if differently. If you're asking about deployes/VDF, then the answer is DeployerWrapper class. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/555128#555128] Start a new discussion in JBoss Microcontainer at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
