Coming back to this issue. I am going to make the JBossMetaData.getVersion() return the version of the schema, not the EJB version. There is an attribute (@XmlTransient) ejbVersion which returns the EJB spec version. It is currently set during EjbJar and JBoss metadata merge and in JBoss50Creator. If there needs to be a schema element or attribute to specify the EJB spec version in the JBoss descriptor or annotation then please open a Jira issue. Thanks.
