Re: How to use Request Factory with JPA Hibernate and PostgreSQL ?

Hmm ok.. so whats the provider?
Found this org.hibernate.ejb.HibernatePersistence one.

I updated the provider and put my class (Worker.java) in the persistence.xml but Iam still get an exception:
When i create the EntityManagerFactory, ReflectiveServiceLayer.invoke(Method domainMethod, Object... args) throws an exception (InvocationTargetException).

So far, i couldnt find any tutorial to get this working.
So any help is much appreciated.

Regards


Thats my current persistence.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<persistence 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_1_0.xsd" version="1.0">

    <persistence-unit name="transactions-optional" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <class>de.mash.server.Worker</class>
   
        <properties>
            <property name="jdbc.driver" value="org.postgresql.Driver" />
            <property name="jdbc.url" value="jdbc:postgresql://localhost:5432/dev_mash" />
            <property name="jdbc.user" value="postgres" />
            <property name="jdbc.password" value="m4nu3l" />
            <property name="show_sql">true</property>
            <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
            <property name="connection.pool_size" value="10" />
            <property name="current_session_context_class" value="thread" />
        </properties>
   
    </persistence-unit>
</persistence>

Heres what i get from the console:

If you want to use Hibernate I guess the persistence provider is wrong. Looks like its the one of EclipseLink.
