Hello,
here is my first draft of a VFS2 Provider which allows you to store files
as Blobs in a Database. I have the problem here, that I need to set the
actual database connection. I decided to only support the DataSource
interface.
I tried to set it via the FS-Options, so you can have multiple filesystems
attached to multiple databases. However this does only work with some
specific simple types, but not generally with Objects. I guess this is a
consequence of the configuration serialisation, but I wonder what can I do
instead?
Currently I added the DataSource as a parameter to the constructor of the
Provider class. This works somewhat, but forces me to have multiple scheme
when I want to access multiple databases.
I plan to support a JNDI variant, where the DataSource is requested from
(String) JNDI name via FS-Options, But this does not work in all
Deployment scenarios, so I really search for the most prefered method to
inject resources. Anybody has an Idea?
