Hi Violeta this property doesnt makes the scope of the resource prototype so we should still have a single instance. That said the JPA usage is a bit harder:
- you need to explicitely define the jta AND non jta datasource (otherwise we create the nonJta on the fly and it fails cause it is not lazy) - I skipped on master (7.x) lazy resource merge in tomcat jndi tree to avoid the first exception to be seen and tomcat to try to process them at startup. This then makes the remove() working as expected - the remove is intended to avoid to consider this virtual property as a real one in the "object factory".
