Currently ejb-jar.xml files in seam examples (1.0.1 GA) use just "<ejb-jar>". How about adding full, standard-compliant declaration? <ejb-jar 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" | version="3.0"> (I had problems with the existing ejb-jar.xmls in IntelliJ IDEA. Of course the IDE should work with the current files, and I complained in their JIRA, too. OTOH the full declaration is cleaner, isn't it?)
