Drops due to absence of jtaDataSource method inLocalContainerEntityManagerFactoryBean
Ficex:

	1. switch to New Spring-orm 3.1.4.RELEASE for better jtaDataSOurce support
	2. clean-up logger output
	3. catch TransactionRequesedException (seems to be EclipseLink issue)

TODO: switch to Hibernate JPA Provider
Transaction tweaks to Service layer
Switch toi Hibernate
