Play Framework JPA postgres

Question

Hello, I’m learning to work with Play! framework and I am having difficulty integrating my application with the Postgres bank, using Hibernate. The application does not use persistence, the bank is working because if I use a standard connection no error occurs. I tried several types of config and many already trigger errors before even accessing the creation of the connection. The most current config is:

application.config:

datasource="jdbc:postgresql://user:password@localhost:5432/db"
datasource.driver=org.postgresql.Driver
datasource.jndiName=defaultPersistence
datasource.schema=dev

persistence.xml:

property name="hibernate.hbm2ddl.auto" value="create-drop"
            property name="hibernate.connection.driver_class" value="org.postgresql.Driver" 
            property name="hibernate.connection.url" value="jdbc:postgresql://localhost:5432/sys_dev" 
            property name="hibernate.default_schema" value="dev" 
            property name="hibernate.connection.username" value="postgres" 
            property name="hibernate.connection.password" value="sql" 
            property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL9Dialect" 
            property name="hibernate.show_sql" value="true" 
            property name="hibernate.current_session_context_class" value="thread" 
            property name="hibernate.transaction.factory_class" value="org.hibernate.transaction.JDBCTransactionFactory"
