Besides that @DataSourceDefinition, I do have a PersistenceUnit java:global/ClientesDS But I get: DEPLOYMENTS MISSING DEPENDENCIES: Deployment "persistence.unit:unitName=test.war#clientes" is missing the following dependencies: Dependency "jboss.jca:name=global/ClientesDS,service=DataSourceBinding" (should be in state "Create", but is actually in state "** NOT FOUND Depends on 'jboss.jca:name=global/ClientesDS,service=DataSourceBinding' **") DEPLOYMENTS IN ERROR: Deployment "jboss.jca:name=global/ClientesDS,service=DataSourceBinding" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.jca:name=global/ClientesDS,service=DataSourceBinding' ** And earlier in server.log I see INFO [org.jboss.resource.connectionmanager.ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=internal/test/test/ClienteDAO/ClientesDS' to JNDI name 'java:internal/test/test/ClienteDAO/ClientesDS' []s, Fernando Lozano ---- Original Message ---- From: fernando(a)lozano.eti.br To: "User development" Sent: Ter, Out 11, 2011, 19:34 PM Subject: [jboss-user] @DataSource not registed on the correct JNDI locaton 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
