Therefore, I shall post here my problem to check that I am doing things rightly. I have a jboss instance, which is currently shared by numerous applications. I mean, various applications are deployed there, most of which we cannot touch or control. Our application is an EAR which includes two modules: an EJB and a WAR. app.ear | |\ |  myEjb.jar \   myWar.war myEjb.jar uses a class let's call it myClass.class (inside app.ear/lib) whose name is shared by other applications running in this JBoss instance. Therefore, I thought that a classloading file like <classloading xmlns="urn:jboss:classloading:1.0"           name="app.ear"           domain="app.ear:loader=app.ear"           parent-domain="DefaultDomain"           export-all="NON_EMPTY"           import-all="true"           parent-first="false"/> would be enough to make sure the classes that both the EJB and the WAR use are the ones inside app.ear. I also added two class loading files for the EJB and the WAR. They are like these: <classloading xmlns="urn:jboss:classloading:1.0"           name="myEjb.ejb"           domain="myEjb.ejb"           parent-domain="app.ear:loader=app.ear"           export-all="NON_EMPTY"           import-all="true"           parent-first="false"/> <classloading xmlns="urn:jboss:classloading:1.0"           name="myWar.war"           domain="myWar.war"           parent-domain="app.ear:loader=app.ear"           export-all="NON_EMPTY"           import-all="true"           parent-first="false"/> But this configuration is not guaranteeing that the actual myClass that the EJB is loading is the one inside the app.ear/lib directory. I don't want to set the parent-domain to "ignored" since there are lots of libraries in the common/lib directory that my application needs (spring, hibernate...) Is there something I should do differently?
