[news.eclipse.newcomer] Re: run configuration and dlls

["Horváth, Csaba" <hcs33@xxxxxxxxxxxxxxxx>]

Hi,

You should use the java.library.path system property and set the directory
of your dll here. You can set it is the run configuration of your program >
Arguments > VM Arguments (-Djava.library.path=directory_of_dll).

By default an Eclipse run configuration starts your application from the
project directory (not from the src as you assumed). You can 'override' this
by setting the 'Working directory' at the same run configuration page as VM
arguments.

HTH,

Csaba
