Im trying to exclude the classes that are only used internally(implementation details..) Using various versions of jboss-deployment-structure files I have been unable to archive this. So I have a rar containing a few jar files with my implementation and some dependencies. adapter.rar - common_v1.jar (contains a class named A) - adapter.jar (contains connection factories, mdb interfaces, activation spec and so on..) placed in packages below int_.nato.adapter.* -META-INF/ jboss-deployment-structure.xml I want my adapter to export the content of adapter.jar to modules using it, but not the other stuff in common_v1.jar.. I tried quite a few variations of the below without success.. jboss-deployment-structure.xml <jboss-deployment-structure>   <deployment>     <exports>                     <exclude path="/**"/>                     <include path=" int_/nato/adapter/"**/>   </exports>   </deployment>    </jboss-deployment-structure> The problem arrises when we try to use the adapter from a web application webapp.war -WEB-INF/lib/common_v2.jar(contains new version of class A and a class B) test.jsp in test.jsp I add <%= A.class.getCLassLoader()%> <%= A.class.getProtectionDomain().getCodeSource().getLocation()%> <%= B.class.getCLassLoader()%> <%= B.class.getProtectionDomain().getCodeSource().getLocation()%> *Now for A.class I get the class packaged insite the rar* *For the B.class I get the class packaged inside the war.* I also tried several variations of jboss-deployment-structure.xml to exclude the classes from import in the webapp (WEB-INF/jboss-deployment-structure.xml) doing so is not preffered as several applications are to be using the adapter..* * In production I end up with NoSuchMethodError since in version 2 of class A there are new methods used within the webapp, that does not exist in v1. Deploys by copying the rar and war to the deployments directory, and everythings works nicely if I just use the same version of common.jar, or just not include it in the webapp.. Any pointers will be appreciated. * * -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/790445#790445] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
