I take your word for it - as I said in another mail, I haven't seen the = 9i driver work on an 8i database myself, and frankly, I have no trust in = the general viability of such a combo. So it'd be great if you can come = up with an 8i-capable OracleLobHandler! (possibly in the Spring 1.1 = timeframe) Maybe we can simply auto-detect the Oracle driver version through = introspection in a single unified OracleLobHandler implementation. = AFAIK, the difference is that the 8i driver didn't have the notion of = temporary LOBs; the Oracle BLOB and CLOB implementation classes = themselves should be compatible. So there's a chance for some code = reuse. Juergen -----Original Message----- From: spr...@li...

Subject: Re: [Springframework-developer] Ready for 1.0 RC1 No, I have personal experience that using the 9i classes12 against an 8i = database has weird (bad) results. As I mentioned in a subsequent message, I do have working code for the=20 8i driver (figured out at great pain :-) ), and can produce a lobhandler = for that. Given the fact that database migration is such a pain, a lot=20 of people are still using 8i, so it's probably worth it for me to do it.
