Hi Lionel

Well I wouldn't really call it a "hack". The author, Pierre-Yves 
Gibello, has put a *lot* of work into it and has chosen to give it away 
for nothing. And it's not just IDB that uses it either - for a while 
Cloudscape used to ship it as well (I don't know if they still do or 
not though).

Could be. I *think* I've heard rumours that RMI can be slower than 
CORBA (anyone out there know for sure?), but I wouldn't have thought it 
would dominate over the normal overheads of networking. 

If RmiJdbc needs improving, say to improve the granularity of row 
fetches, well it *is* open source...

When I used to make my living from selling IDB the target market was 
very definitely embedded and out of the box demo applications. That's 
very much what IBM WebSphere, JRun and many others used it for. 

But really, how you "market" a product makes no difference to the 
product itself. A database server is just an embedded database with a 
networking front end. Internally, IDB doesn't care whether connections 
come over the network or from the same JVM. It'll apply the same 
locking and synchronization methods regardless.

IDB+RmiJdbc is conceptually no different from any other database with a 
networked driver. It's just that Pierre-Yves has managed to come up 
with a very simple way to network almost any embedded database.

Why not just try RmiJdbc out? You never know - you might be pleasantly 
surpised!

Regards

Pete
