Jackrabbit expects a particular Oracle driver
Hi all.
I'm testing Jackrabbit 1.4 with Oracle, and I'm having a little problem.
In OracleFileSystem.init(), there's a call to initialize oracle.sql.BLOB. The problem is that I'm
not using the standard Oracle driver, and it doesn't provide that class.
There are a few solutions to this that I can take care of in my app, but I think Jackrabbit should
not fail just because you're not using the driver it expects to. The bigger problem is that it
shouldn't expect a particular driver.
WDYT?
Regards,
Esteban Franqueiro

Done.
I'll try to make this changes as soon as I can finish with my current work.

sounds good. do you want to create to create a related jira issue?

You're right. Maybe we can create a new class for Oracle 10+, Make it inherit from DbFileSystem, and
override the createSchema(), and table space related methods, which are the ones that need special
handling. Furthermore, we could refactor the current OracleFileSystem and break it into two clases,
one of them to keep the current behavior and a new one to keep the common code (which we could
rename to OracleBaseFileSystem or similar, for the reason you said). Then we make the
Oracle10FileSystem inherit from the latter.
WDYT?

Yes, I thought of that aswell. However, just renaming the existing
class is probably not an option since it would break backward
compatibility.
What do you suggest? Any other good ideas?

Maybe we should rename this class as Oracle9FileSystem or Oracle101FileSystem, or something similar,
and provide another impl that works with newer versions and doesn't depend on that class?
Thanks!

in an ideal world we'd only need one DbFileSystem and
DbPersistenceManager implementation
in jackrabbit ;) however, certain (more or less subtle)
vendor-specific differences/features
needed to be addressed in specialized subclasses.
OracleFileSystem is just an example of this. the oracle jdbc drivers
prior to version 10.?
only exposed Blob support through vendor specific classes, hence the
oracle.sql.BLOB
reference.
