EJB annotations ignored if classes are packaged as JBOSS modules ---------------------------------------------------------------- Key: WFLY-4386 URL: https://issues.jboss.org/browse/WFLY-4386 Project: WildFly Issue Type: Bug Components: Class Loading, EJB Affects Versions: JBoss AS7 7.1.1.Final Reporter: Tihomir Meščić Assignee: David Lloyd I have an EJB that writes something to the DB and I have a custom checked exception that is marked as @javax.ejb.ApplicationException(rollback=true), which means that when the exception is thrown, transaction should be rollbacked. {code:title=Test.java.java|borderStyle=solid} @ApplicationException(rollback=true) public class MyException extends Exception { {code} This exception is packaged in a separate JAR. When this JAR is included in the lib/ folder of the EAR with my EJB, everything works as expected (when the EJB throws MyException, the transaction is rollbacked). However, when this JAR is deployed as a JBOSS module (so, in jboss_folder/modules/... folder), and the EAR declares a dependency on this module (MANIFEST.MF -> Dependencies: ....) , then the transaction is NOT rollbacked. So the EJB container ignores the annotation. One workaround (that I don't really like) is to specify that this is an application exception in the jboss-ejb3.xml (then, the transaction will be rollbacked).
