Question

I get this error when I try to save a simple Item to my H2 db:

"javax.persistence.PersistenceException: The default EbeanServer has not been defined ? This is normally set via the ebean.datasource.default property. Otherwise it should be registered programatically via registerServer()"

my play application.conf file

 # Database configuration
    # ~~~~~
    # You can declare as many datasources as you want.
    # By convention, the default datasource is named `efault
    db.default.driver=org.h2.Driver
    db.default.url="jdbc:h2:mem:play"
    db.default.jndiName=DefaultDS
    db.default.user=sa
    db.default.password=""

    # JPA configuration
    # ~~~~~
    # You can declare as many Ebean servers as you want.
    # By convention, the default server is named `default`
   jpa.default=defaultPersistenceUnit  
   ebean.datasource.default=DefaultDS
   ebean.default="models.*"

To use a JNDI DataSource you need to set:

ebean.datasource.factory=jndi

And datasource.default as the JNDI DataSource name. You can additionally override ebean.datasource.jndi.prefix which defaults to java:comp/env/jdbc/.
