This document discusses OSGi specifications for JNDI and JDBC services. It describes how the JNDI Services Specification handles lookup of InitialContextFactory and ObjectFactory services and supports legacy JNDI implementations. It also outlines the JDBC Services Specification for publishing DataSourceFactory services and creating connections. Finally, it mentions a Derby bundle that provides a DataSourceFactory for the Derby database.

1. Gemini Naming

2. OSGi JNDI Services Specification Specifies a service-based approach to provding JNDI services Handles services coming up and down Supports legacy services e.g. Existing LDAP, COS, RMI, DNS services are supported

3. Singletons for ObjectFactoryBuilder and InitialContextFactoryBuilder to allow overriding Allows use of standard JNDI API Careful: “Lifecycle mismatch” Special handling of URLs URL-based way of looking up OSGi services

4. JNDIContextManager org.osgi.service.jndi.JNDIContextManager service newInitialContext()/newInitialContext(Map)

5. newDirectoryContext()/newDirectoryContext(Map) Search for matching InitialContextFactory services and return a wrapped version of them

6. If no appropriate InitialContextFactory found, search for appropriate InitialContextFactoryFactoryBuilder services.

7. JNDIProviderAdmin Conversion between references and objects

8. org.osgi.service.jndi.JNDIProviderAdmin service getObjectInstance() methods Search for ObjectFactory services the are appropriate
