Hi,
I try to build a Java SE application based on OSGi 4.2(+). I have read a lot of blogs, documentation, tutorials but it seems, that (almost) all of them point to server side contexts. I have the aries + eclipselink bundles in my classpath. I added a bundle that has dependencies to the eclipselink bundles and the exposes a service providing the PersistenceProvider. So to say, it is my jpa persistence provider bundle. Further bundles provide each one or several DataSourceFactories (for each database platform, connection-type respective (e.g. mysql, derby.client, derby.embedded, and so on). As third part there is a persistence bundle, containing the Meta-Persistence header in MANIFEST.MF and a persistence.xml and several entity classes. The same bundle registers a service exposing a datasource obtained from on of the DataSourceFactory services (e.g. mysql) containing the connection information for database access. These bundles are started at start-level 3 and auto-start set to true. The aries jpa-container bundle is started on level 2 with auto-start = true. For Testing I added a fragment bundle to the persistence bundle that tracks EntityManagerFactory Service. This service runs ok but obtaining an EntityManager from the EntityManagerFactory results in an exception (see the following stack trace). Because I do not know JEE technology, I do not understand, where the problem lies. Can anyone give me a hint? Thank you Christian persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence";
