Thank you for your quick reply. My .ear file contains: bank-ejb.jar app-client.jar web-client.war aopexamplelib.aop My application.xml: | <?xml version="1.0" encoding="UTF-8"?> | <application xmlns="http://java.sun.com/xml/ns/j2ee" version="1.4" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com /xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd"> | <display-name>JBossDukesBank</display-name> | <description>Application description</description> | <module id="EjbModule_1184078196095"> | <ejb>bank-ejb.jar</ejb> | </module> | <module id="JavaClientModule_1184078196048"> | <java>app-client.jar</java> | </module> | <module id="WebModule_1184078196158"> | <web> | <web-uri>web-client.war</web-uri> | <context-root>bank</context-root> | </web> | </module> | <module> | <java>aopexamplelib.aop</java> | </module> | | <security-role> | <role-name>BankAdmin</role-name> | </security-role> | <security-role> | <role-name>BankCustomer</role-name> | </security-role> | </application> | So, I used ".aop" file to deploy. My aopexamplelib.aop file contains: com/sun/ebank/aop/SimpleInterceptors2.class META-INF/jboss-aop.xml The class I want to weave it is in "bank-ejb.jar", "com.sun.ebank.ejb.tx.TxControllerBean". My situation is: "injbossaop" example can be run perfectly. All configuration of JBoss has been done. When depolying my Duke's Bank application, no any error occurs. When running the application, only "MyServlets" has been woven. (Prints out debug msg). Any other beans have not been woven. (Doesn't print out debug msg). Pleas let me know if you need any other info. Thanks. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4062499#...
