[eclipselink-users] Overwrite session manager settings

["Philipp Kursawe" <phil.kursawe@xxxxxxxxx>]

Is it possible to overwrite the settings made in the persistence.xml when  
creating the EntityManager using an EntityManagerFactory.create(Map)?
It seems like that the properties I am handing in are not valued.

Is it in any other way possible to set certain persistence.xml values from  
within the program? I mean I cannot seriously be asked to put login  
credentials inside a JAR?
I would like the user to configure those values and feed them to  
EclipseLink programmatically not from the persistence.xml.

Thanks for your help!
Phil
