Hi, I user jboss 5 and have problem with persistence.xml deploy . Persistence.xml uses OracleDS that is deployed, I can see it in jmx-console. I allways got this message : DEPLOYMENTS MISSING DEPENDENCIES: Deployment "persistence.unit:unitName=#ModuleAdmCbPersistence" is missing the following dependencies: Dependency "jboss.jca:name= java:/OracleDS ,service=DataSourceBinding" (should be in state "Create", but is actually in state "** NOT FOUND Depends on 'jboss.jca:name= java:/OracleDS ,service=DataSourceBinding' **") DEPLOYMENTS IN ERROR: Deployment "jboss.jca:name= java:/OracleDS ,service=DataSourceBinding" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.jca:name= java:/OracleDS ,service=DataSourceBinding' ** This is part of persistence.xml file <persistence-unit name="ModuleAdmCbPersistence" transaction-type="JTA"> org.hibernate.ejb.HibernatePersistence <jta-data-source> java:/OracleDS </jta-data-source> </persistence-unit> and this is oracle-ds.xml file <local-tx-datasource> <!-- The jndi name of the DataSource, it is prefixed with java:/ --> <!-- Datasources are not available outside the virtual machine --> <jndi-name>comp/env/jdbc/OracleDS</jndi-name> <connection-url>jdbc:oracle:thin:@localhost:1521:XE</connection-url> <!-- The driver class --> <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter </exception-sorter-class-name> <!-- The login and password --> <user-name>zlaja</user-name> zlaja! </local-tx-datasource> Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214946#...
