Hi!
I have a problem.
The situation is the following: i wrote an application which serialize on a file (dati.dat).
The application has this structur:
- pachage application
- package gui
- file dati.dat

I make the jar of my application wiht Eclipse (export->runnubla jar).

I put the jar e the dati.dat file in a folder on linux. When I opne it with double click on the jar the application doesn't find the dati.dat file.
The jar find dati.dat only when dati.dat is in the home directory.

If I ran the jar from the shell ther is no problem. the application find the dati.dat when it's in the same folder of the jar.

I've tried the following thing:

giving then

for the path's file but the problem is still here.


Printing to screen the path, I saw that the path is correct, but...


The jar must work on Linux and on windows.
In windows I have no problem. Double clic on the jar and all work properly.

Anyone can hel me?
Thanks.

the system property "user.dir" is the current working directory

when starting your jar from jexec (double-click) it is running
in your Window Manager's shell.

The Window Manager's current working directory in UNIX always
is the user's home directory.

Furthermore, you shouldn't use / (slash forward) to separate
path elements.

Either use java.io.File to build the path or java.io.File.separator
when concatinating Strings.

Hope that helps
Matt
 
It is sorta covered in the JavaRanch Style Guide.
