Hi there, According to my understanding of http://javahowto.blogspot.com/2010/04/datasourcedefinition-examples-in-ja... and http://java.sun.com/javaee/6/docs/api/javax/annotation/sql/DataSourceDefi... The following annotation, which is part of a no-interface SLSB defined inside a test.war package: @DataSourceDefinition( name="java:global/ClientesDS", className="org.hsqldb.jdbcDriver", url="jdbc:hsqldb:file:/tmp/data/cliente", user="sa", password="") Should register "java:global/ClientesDS" on the application server JNDI three. But when I deploy under JBoss AS 6.1.0.Final, the DataSource is registed as "java:internal/test/test/ClienteDAO/ClientesDS" Am I wrong or is JBoss AS violating the spec? []s, Fernando Lozano
