JPA and then?
Posted on September 17, 2010
Some tests with JPA (EclipseLink as implementation) were not successful. I need a persistence.xml file to define different persistence contexts, but what is if I need a new context at runtime? I have to provide such an xml file, but how I can merge the new one with the already existing file without restarting the core system? It’s not nice to define all classes within the xml too, so I have closed this chapter.
I have found another interesting approach: Apache Cayenne. It seems to meet the requirements, especially the use of events during insert/update/commits etc. would allow me to integrate the ACS component of PhOSCo. So I’m thinking about a migration to this framework. Maybe I only can get some ideas from there or the complete framework. I will see.
