The problem was solved when i had this line in my persistence.xml file : <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
And now it works. I think that i will write a little tutorial on this subject because it was really what i needed and didn't find. It is a lot of little things and i am on this "test" from last week and i solve it just after exposing my problem here !
