AFAIK there isn't one. You have to write the middleware layer yourself. I wrote a simple one using Indy10. Since Delphi 2009, DataSnap has been based on Indy anyway.

I've never tried it in Lazarus but the source code is available so you can try to port it

Actually I'm just asking, I'm not planning to use DataSnap even in Delphi, and even once.
Why NOT?
There are lots of database server like:
mySQL,
Firebird,
msSQL,
Oracle
etc.,

So, why bother using that, while we can make fast, using those servers
3tier?
1. Application Development
Using Lazarus Free Pascal  Language
2. Database Server
mySQL (linux/windows)
Lazarus Free Pascal Win Forms with mySQL Server (linux/windows)
3. Clients
Lazarus Free Pascal Win Forms with mySQL connection (linux/windows)


thanks

btw, I've read your post before asking this

I haven't used it myself, but some Delphi programmers I know were quite happy with it.
