Actually the rules are still not clear. Section 5 and 12 contradict each other. The EE6 RI, JBossAS6 and TomEE and WAS did behave like in section 5 (1 BDA per ee-module) whereas Weld-2 behaves like in section 12.

There is no merging, thus an app can contain three types of archives :Non bean archives,Implicit bean archives,Explicit bean archives.  Antoine Sabot-Durand Le 1 mai 2015 à 23:03, Emily Jiang <emijiang6(a)googlemail.com&gt; a écrit : I have a question on bean archives. For the jars under web-inf\lib, are they individual bean archives or they should be merged   with web-inf\classes files and use the beans.xml under web-inf\ to form one bean archive? If they are merged together to form one bean archive, what will happen if they have their own beans.xml under Meta-inf dir? Below is the what spec says, but it does not mention the jar under web-inf\lib. The spec should make this situation clear. In the CDI1.2 spec: When determining which archives are bean archives, the container must consider: • Library jars, EJB jars or application client jars • The WEB-INF/classes directory of a war • Directories in the JVM classpath The container is not required to support application client jar bean archives. A Java EE container is required by the Java EE specification to support Java EE modules. Other containers may or may not provide support for war, EJB jar or rar bean archives. The beans.xml file must be named: • META-INF/beans.xml , or, • in a war, WEB-INF/beans.xml or WEB-INF/classes/META-INF/beans.xml. -- Thanks Emily ================= Emily Jiang ejiang(a)apache.org _______________________________________________ cdi-dev mailing list cdi-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/cdi-dev Note that for all code provided on this list, the provider licenses the code under the Apache License, Version 2 (http://www.apache.org/licenses/LICENSE-2.0.html).
