Re: InstantDB: image data type


Interesting. I tried a little program to read in a small gif, store it in
the database and then get it back and put it in a file. When I used
InstantDB's native driver this worked fine, but just like you, when I tested
using the RmiJdbc driver I got some corruption (oddly enough the top of the
gif was fine and the bottom half was displaced to the right by about 50% - I
don't know enough about gifs to know what this means though).

I've copied Pierre-Yves Gibello on this, just in case this is a known
problem. If I get a chance, I'll look into this further.
