Re: FileNotFoundException when running JAR Application through jSwat

Do you normally run your program from a particular directory? That is,
if you launch it from c:\myproj and the data file is in
c:\myproj\data\user.dat, then your program is using a relative path to
find its data file.

But when launched from JSwat, your program will inherit the current
working directory of JSwat. So you launch JSwat from c:\jswat then your
program will look for c:\jswat\data\user.dat and not find the data file.

Or, it could be there's an element missing or mistyped in the classpath,
assuming your program uses the classpath to find the data file.
