Java Forum / General / April 2008Swing and path
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.

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.

I would use Preferences instead of doing this. It's what they are meant for.  SignatureKenneth P. Turvey <kt-usenet@squeakydolphin.com> > I would use Preferences instead of doing this.

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. > Well, u spelled launch wrong, but other than that you had good If you're going to correct someone's spelling, you should do it without deliberate misspellings of your own.
