Hi Puybaret,

Thanks for the reply and suggestion, sorry for giving you so much trouble. [:(]

Yes, i have read your reply and you have place another thread post which has the same problem as me do for running a source project with Eclipse[Here ].I have read that post also. [:)]

Finally i can run the source project in my computer. [:))]

I am using the
-Djava.ext.dirs="${workspace_loc:SweetHome3D}/lib";"${workspace_loc:SweetHome3D}/lib/windows"

as the vm argument and it works fine.

But when i try with another vm argument
-Djava.library.path="${workspace_loc:SweetHome3D}\lib\window"

the same old problem still occurred which the program can't find the native library in java.library.path. Any idea? [:-/]

Regards
