Swing and path

[wbrzozow]

Hello
I have the following problem. I have been writing a Swing application.
In this application in several places I use JFileChooser. I try to
find a pattern or a good solution for remembering path to directory
for each place, where the JFileChooser was used. In order to meet my
boss requirements my application after lunching should remember paths
that were used before.

I hope that is clear, because my English isn’t very good.

One approach could be to save it off as a properties file. Jakarta
has an abundance of Java tools and they happen to have a property
persistence tool: http://commons.apache.org/configuration/howto_properties.html

You can save the properties file to a place on the user's computer and
then load it when the program opens.

Hope this helps!

Well, u spelled launch wrong, but other than that you had good
english. What you basically could do is every time the user selects
ok and clicks a file you set a variable to what that file's directory
was then when your program exits (you could put this code in the close
method of a WindowListener on you main frame) you simply write the
data to a log file. Then every time you program loads you can read
this file in and set all your file dialogs to start at this directory
or the last file chosen.

I would use Preferences instead of doing this.  It's what they are meant
for.

I am thinking about advantages and disadvantages both solutions :
Preferences and Apache Properties. I probably use Preferences, but a
have only one question. Where the configuration data are stored in
Linux, Unix system.
