[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: Referenced datasource not found with JBoss 5.0 (Beta4)

I think what "depryf" is trying to do is, define a resource-ref named "app-specific/datasource" for the "java:/app/datasource" datasource and then use java:comp/env/app-specific/datasource as the jndi-name for looking up the datasource. depryf, Going by the exception stacktrace, i guess this is what is happening: anonymous wrote : | at $Proxy109.getDbColumnInfo(Unknown Source) | at com.imsweb.seerdms.shared.util.PropertyMappingsUtils.initialize(PropertyMappingsUtils.jav | a:139) | at com.imsweb.seerdms.shared.util.PropertyMappingsUtils.initialize(PropertyMappingsUtils.jav | a:111) | at com.imsweb.seerdms.web.shared.configuration.ConfigurationServlet.init(ConfigurationServle | t.java:158) | at javax.servlet.GenericServlet.init(GenericServlet.java:212) anonymous wrote : at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:629) | at javax.naming.InitialContext.lookup(InitialContext.java:392) | at com.imsweb.seerdms.shared.api.ServiceLocator.lookup(ServiceLocator.java:631) | at com.imsweb.seerdms.shared.api.ServiceLocator.getConnection(ServiceLocator.java:597) | at com.imsweb.seerdms.app.shared.dao.hibernate.HibernateCommonDataDAO.getDbColumnInfo(Hibern | ateCommonDataDAO.java:97) You have a resource-ref defined in your web component, in which you have a startup servlet. This startup servlet will then have access to the java:comp/env/app-specific/datasource datasource. Based on the exception stacktrace, i can see that in the init method of your startup servlet you are looking up an EJB and invoking an method on the EJB. The EJB then (i guess through a DAO) tries to lookup the datasource using java:comp/env/app-specific/datasource jndi-name. This is not going to work because, the EJB has its own java:comp/env namespace. Since you have specified the resource-ref for your web component and not the EJB component, the java:comp/env namespace will be empty for the EJB and hence the lookup fails. Just to verify this, you can lookup the datasource "java:comp/env/app-specific/datasource" directly in the init method of the startup servlet. I believe you should be able to successfully get the datasource. If you want the datasource to be available at java:comp/env namespace of the EJB, then you will have to define a resource-ref through the ejb-jar.xml and jboss.xml for the EJB.
