[jboss-user] [Installation, Configuration & Deployment] - Why loading the class in EJB jar rather than the one in war

Hi everyone, This question is about the class loader config in JBoss. I am currently deploying a EJB jar and a war in JBoss 4.0.3SP1. They are mdb.jar and app.war and are placed in the server/default/deploy folder separately. In the mdb.jar, I have a ClassA.class, i.e. mdb |_ ClassA.class (version 1) |_ META-INF In the app.war, I also have a ClassA.class but it contains some system out in this version, i.e. app |_ WEB-INF | |_ classes | |_ClassA.class (version 2 w/ system out) |_ ... When I startup my JBoss, I don't know why the web application uses the ClassA in the mdb.jar which has no system out? My Question is: 1. Do the jar and the war share a common class loader ? 2. After I've read the doc about JBoss setting, I config the jboss-web.xml in the app.war as follow but the problem still exists. <jboss-web> | <class-loading java2ClassLoadingCompliance="false"> | <loader-repository> | com.cherrypicks:loader=chs.war | <loader-repository-config>java2ParentDelegation=false</loader-repository-config> | </loader-repository> | </class-loading> | </jboss-web> Even though I redeploy the app.war, it still loads the ClassA in mdb.jar. Can anybody explain it ? My jboss tomcat setting is like below.. <attribute name="Java2ClassLoadingCompliance">false</attribute> | <attribute name="UseJBossWebLoader">false</attribute> 3. I want different deployments use their own classes in jar/war and don't let them to use the classes (with same name) in other deployment, i.e. separate class loader. How can I do that ?
