Hello Christian,
I tried something that seems working but I'd like a confirmation that
I'm not writing a bomb-code :)
I separated my persistence bundle (META-INF/persistence.xml, Entity
classes,..) (db-common) from the blueprint.xml file.
I created a bundle database-mysql that only contains a blueprint file
for the mysql DB configuration (db-mysql), and I'm thinking of creating
a similar bundle with a blueprint.xml file for a derby DB configuration
(db-derby).
After that, I'd have to install one of those bundles (db-mysql or
db-derby) with my initial bundle (db-common) to make it work.
Right know, I tested this with the bundles db-mysql and db-common and it
seems working.
Is it an OSGi compliant implementation ?
Best regards,
Khadija

This is possible in two ways.
You can use the
http://www.osgi.org/javadoc/r4v42/org/osgi/service/jdbc/DataSourceFactory.html
sepcified in the OSGi spec if your drivers supports it.
If not then you can try this tutorial:

Basically the idea is to publish a DataSource as an OSGi service using
a separate blueprint file and using the service in your user bundle. This
way you can have the filter to reference the OSGi service in a config
of your user bundle. So you can switch db types.

Hello everyone,
I'd like to configure the database type (mysql, derby,..) from an
external configuration type. Is this possible using blueprint ?
