It looks that a DeploymentUnit(DU) contains multiple DeploymentContext(DC) and each DC is linked to only one DU . Considering the deployment as | A.sar(DC1) | -->B.sar(DC2) | ---------->C.ear(DC3) | ---------->D.ear(DC4) | --->E.ear(DC5) | ---------->G.war(DC6) | ----------->H.war(DC7) | ---->I.jar(EJB) (DC8) | And all the DC's for a Tree which is represented by DU , this is logical relationship . Is this how it goes ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989646#...
