Subject Re: How to override persistence.xml properties
Date Mon, 02 May 2011 14:24:00 GMT
Hi Rick,

Good point, I'm now passing all the sys properties in explicity and it
works fine.

	 Properties props = new Properties();
	 props.setProperty("openjpa.Log", "log4j");
          props.putAll(System.getProperties());
	EntityManagerFactory factory =
Persistence.createEntityManagerFactory("su3", props);


Thanks!

Joel
