[jboss-user] [JNDI and Naming] - Reference cannot be cast to DataSource w/ standalone app client

Steve Maring [http://community.jboss.org/people/stevemaring] created the discussion "Reference cannot be cast to DataSource w/ standalone app client" To view the discussion, visit: http://community.jboss.org/message/627473#627473 -------------------------------------------------------------- I am trying to unit test some JPA2 DAO classes I wrote using Maven.  The persistence.xml looks like this: <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0"     xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">     <persistence-unit name="lifesmartEntityManager" transaction-type="RESOURCE_LOCAL">         <provider>org.hibernate.ejb.HibernatePersistence</provider>         <non-jta-data-source>*MyDS*</non-jta-data-source>         <properties>             <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />             <property name="hibernate.show-sql" value="true" />         </properties>     </persistence-unit> </persistence> I have deployed the DataSource to a running instance of AS 6.1.0.Final and confirmed that the global JNDIView has: +- *MyDS* (class: javax.sql.DataSource) When I try to run my tests, which rely on Hibernate EntityManager to lookup and associate the DataSource with the persistence-unit, I get: 08:05:12,185 ERROR [DatasourceConnectionProvider] Could not find datasource: *MyDS* *java.lang.ClassCastException: javax.naming.Reference cannot be cast to javax.sql.DataSource*         at org.hibernate.connection.DatasourceConnectionProvider.configure(DatasourceConnectionProvider.java:75)         at org.hibernate.connection.ConnectionProviderFactory.newConnectionProvider(ConnectionProviderFactory.java:143)         at org.hibernate.ejb.InjectionSettingsFactory.createConnectionProvider(InjectionSettingsFactory.java:51)         at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:91)         at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2833)         at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2829)         at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1840)         at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:902)         at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:57)         at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48) I am certain that it is not truly a naming problem, because when I change the name to something bogus in the persistence.xml and run the test again, the error is different: 08:25:34,525 ERROR [DatasourceConnectionProvider] Could not find datasource: *YourDS* javax.naming.NameNotFoundException: *YourDS* not bound         at org.jnp.server.NamingServer.getBinding(NamingServer.java:771) Some have suggested this is really a classpath issue and I have started adding standalone remote client oriented libs in a bit of a shotgun approach.  So far, nothing has helped.  My test classpath, at this point, contains these declared artifacts, and the dependencies declared in their poms: slf4j-log4j12 testng jnp-client jboss-remoting jbosssx-client jboss-security-spi hibernate-validator jboss-logging jboss-ejb3-vfs-spi jboss-ejb3-core jboss-kernel jboss-dependency jboss-classloading-vfs jboss-classloading jboss-classloader jboss-service-binding-core jboss-metadata-client jboss-transaction-api_1.1_spec jboss-jmx jboss-integration jboss-vfs jboss-reflect jboss-common-core jboss-serialization hibernate-jpa-2.0-api hibernate-entitymanager I am, perhaps, still missing an artifact? -Steve Maring Tampa, FL -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/627473#627473] Start a new discussion in JNDI and Naming at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
