Hi, Is there any progress on this? I think it is still a problem in jboss 5 beta 4. If you use the 2.0 dtd for your ejb-jar.xml file: - <?xml version="1.0" encoding="UTF-8"?> | <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd"> | <ejb-jar> | ... | all ejb 3 beans in the jar are ignored. Vice versa, if you use the ejb 3 schema for your ejb-jar.xml file: - <?xml version="1.0" encoding="UTF-8"?> | <ejb-jar version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"> | ... | all ejb 2 beans are ignored Is it a mandatory to put different ejb versions in different ejb modules?
