Unused private methods in DB.java

[alcarraz]

Just by chance, I just spotted these 4 unused private methods in DB class, well two are used by just by the other two, should we remove them? Or make them protected if they have some use?

jPOS-EE/modules/dbsupport/src/main/java/org/jpos/ee/DB.java

Lines 191 to 249 in 8c47d70

	private void configureProperties(Configuration cfg) throws IOException
	{
	String propFile = System.getProperty("DB_PROPERTIES", "cfg/db.properties");
	Properties dbProps = loadProperties(propFile);

	{
	cfg.addProperties(dbProps);
	}
	}

configureProperties seems to be for putting db properties in a Hibernate Configuration while the other seem to be for obtaining properties from a hibernate configuration, they have been there for 8 years, since commit dd9aa78
