I have an use case to fuel the classloading discussion...
An app running in OSGI environment:
The application runs in a thread which classpath is isolated from other
resources such as PC classes, bootstrap configuration file (.properties,
jdoconfig.xml or persistence.xml), jdo implementation and jdbc drivers.
So the classpath is organized as:
System classpath
jdo.jar (CP 0)
Application classes (CP 1) - jdo classes loading delegated to CP 0
bootstrap configuration file in (CP 2)
jdo implementation in (CP 3) - jdo classes loading delegated to CP 0
jdbc drivers in (CP 4)
Pseudo code:
//current thread classloader is CP1
Map props = CP2.load bootstrap file();
props.put("org.jpox.primaryClassLoader",CP4);
PersistenceManagerFactory pmf =
JDOHelper.getPersistenceManagerFactory(props,CP2);
