override the persistence unit provider property

[hypnosat7]

Hello,

  I've add a provider property in my jndi.properties file to avoid using openjpa provider:
# override properties of the "educaPU" persistence unit
educaPU.provider = org.eclipse.persistence.jpa.PersistenceProvider
educaPU.jta-data-source = educaDatabase
educaPU.non-jta-data-source = educaDatabase
educaPU.eclipselink.target-database = org.eclipse.persistence.platform.database.HSQLPlatform
educaPU.eclipselink.ddl-generation = drop-and-create-tables
educaPU.eclipselink.ddl-generation.output-mode = both


But I still see OpenJPA as a provider:
INFO - PersistenceUnit(name=educaPU, provider=org.apache.openjpa.persistence.PersistenceProviderImpl)


So how can I do to enforce the use of eclipselink ?
Thanks

The overrides go directly to the <persistence-unit>/<properties>  
element.

There are standard system properties for setting provider,  
datasources, and transaction type if you do not wish to specify them  
in the persistence.xml.

  - javax.persistence.provider
  - javax.persistence.transactionType
  - javax.persistence.jtaDataSource
  - javax.persistence.nonJtaDataSource


I wouldn't worry about setting the datasource names.  In most cases we  
can figure that out automatically.

I'm using an embedded openejb, can I set the "javax.persistence.provider" property in a file ? in the jndi.properties it doesn't work.
Thanks.
