[Java-2.5] No Persistence provider for EntityManager named defaultPersistenceUnit

[Johan Dahlberg]

I am starting with a new project at work and this time I am starting with 2.5 instead of 2.4. I have set up a small project that is supposed to use JPA. But when I'm trying to inject JPAApi to my controller I get this error:

No Persistence provider for EntityManager named defaultPersistenceUnit

 I have the default conf file from the "play-java-intro" template. Modified with the following:

db {

  default {

    driver=com.mysql.jdbc.Driver

    url="jdbc:mysql://localhost/dbname"

    username="root"

    password="secret"

    jndiName=DefaultDS

    logSql=true

  }

}

jpa.default=defaultPersistenceUnit

and conf/META_INF/persistence.xml:

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"

             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"

             version="2.1">

    <persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">

        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>

        <non-jta-data-source>DefaultDS</non-jta-data-source>

        <properties>

            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect"/>

        </properties>

    </persistence-unit>

</persistence>

build.sbt dependencies:

libraryDependencies ++= Seq(

  javaCore,

  javaJdbc,

  javaJpa.exclude("org.hibernate.javax.persistence", "hibernate-jpa-2.0-api"),

  javaWs,

  "mysql" % "mysql-connector-java" % "5.1.38",

  "org.hibernate" % "hibernate-entitymanager" % "5.1.0.Final",

  "org.hibernate" % "hibernate-java8" % "5.1.0.Final",

  "org.hibernate.javax.persistence" % "hibernate-jpa-2.1-api" % "1.0.0.Final"

)

I haven't had any problems with JPA in 2.4 so this feels weird. I don't do anything with JPA except injecting JPAApi.

I think you just mistyped META-INF (it's a dash, not an underscore). It looks to me that it's just not picking up persistence.xml.

Ah, thanks. I double checked everything except that.
