Hi everybody, My previous post contained configuration info for a build error I'm getting, but incorrectly pointed to the error that was the problem. After working another couple hours, I have the following config on JBoss 4.0.5GA,jboss-aop 1.5.2GA, and JBossCache 1.4.1GA. Pojo class @org.jboss.cache.aop.annotation.PojoCacheable public class ChatSubscriber implements java.io.Serializable { private TopicConnection topicConnection; private TopicSession topicSession; private Topic topic; private TopicSubscriber receiver; @org.jboss.cache.aop.annotation.Transient String message; etc.} jboss-aop.xml <aop> | <prepare expr="field(* @org.jboss.cache.aop.AopMarker->*)" /> | <prepare expr="field(* $instanceof{(a)org.jboss.cache.aop.InstanceOfAopMarker}-&gt;*)&quot; /> | <prepare expr="field(* @org.jboss.cache.aop.annotation.PojoCacheable->*)" /> | <prepare expr="field(* $instanceof{(a)org.jboss.cache.aop.annotation.InstanceOfPojoCacheable}-&gt;*)&quot; /> | </aop> build.xml <aopc compilerclasspathref="classpath" verbose="true"> | <classpath path="${cache.classes.dir}"/> | <src path="${cache.classes.dir}"/> <!-- --> | <include name="**/ChatSubscriber.class"/> | <aoppath path="META-INF/jboss-aop.xml"/> | <aopclasspath path="${cache.classes.dir}"/> | </aopc> and when I run aopc, I get the following error: [aopc] [debug] Passed in instrumentor: null [aopc] [debug] Defaulting instrumentor to: org.jboss.aop.instrument.ClassicInstrumentor [aopc] [debug] jboss.aop.class.path: C:\Zen_chat\ChatSample\server\Chat\lib\WEB-INF\classes [aopc] [debug] Looking for aspects in: oracle.otnsamples.oc4jjms.ChatItem [aopc] [debug] Looking for aspects in: oracle.otnsamples.oc4jjms.ChatPublisher [aopc] [debug] Looking for aspects in: oracle.otnsamples.oc4jjms.ChatSubscriber [aopc] [debug] Looking for aspects in: oracle.otnsamples.oc4jjms.GetMessage [aopc] [debug] Looking for aspects in: oracle.otnsamples.oc4jjms.SendMessage [aopc] [debug] jboss.aop.search.classpath: 'null' true [aopc] [debug] jboss.aop.path: C:\Zen_chat\ChatSample\server\Chat\META-INF\jboss-aop.xml [aopc] jboss.aop.path[0]: C:\Zen_chat\ChatSample\server\Chat\META-INF\jboss-aop.xml [aopc] [deploying] file:/C:/Zen_chat/ChatSample/server/Chat/META-INF/jboss-aop.xml [aopc] [trying to transform] oracle.otnsamples.oc4jjms.ChatSubscriber [aopc] [debug] There are no caller pointcuts!
