Problems in testing Java Mapscript

[Rodrigo Del C. Andrade]

Gaia,

Risking stating the obvious or being annoying: are you sure those dlls 
are in the system (not user) PATH? Is their directory exported in the 
path or their parent directory? Have you rebooted windows after 
declaring it? I have seem similar errors on linux and all were related 
to environment variables. I have next to nil experience with MS4W, but 
thats were I would put my money on.
As Umberto said, what makes you suspect sde91.dll? Is there something in 
the logs you haven't sent?

Good luck.

Rodrigo
