Looking at your 2nd link, will *jboss-deployment-structure.xml* file solve my problem, by preventing automatic dependencies from being added? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/614506#614506] Start a new discussion in JBoss AS7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]

As I already mentioned here http://community.jboss.org/message/615408#615408 http://community.jboss.org/message/615408#615408 dependency exclusions seem to work somewhat strangely. I've got an ear with lib directory and four wars MANIFEST.MF Class-Path entries in these wars reference libraries from the ear lib directory Then I've got jboss-deployment-structure.xml <jboss-deployment-structure>   <ear-subdeployments-isolated>true</ear-subdeployments-isolated>   <deployment>     <exclusions>       <module name="org.hibernate" />       <module name="org.hibernate.validator" />     </exclusions>   </deployment> </jboss-deployment-structure> Which doesn't seem to behave like I would expect. I can see that with these exclusions the behavior changes a little (when compared with no exclusions at all), but server's hibernate stuff is still being used. I had to add a sub-deployment entry with the same exclusions for each war to get closer to the expected state. Is is a normal behavior? It looks a quite strange to me, I'd expect setting these exclusions at deployment level would affect the whole ear but it doesn't seem so. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/615428#615428] Start a new discussion in JBoss AS7 Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
