I am working on a Java Desktop program which upon its installation will designate a default database directory and working directory. Where should I save such information so that the next time the user open the program, the program knows where to look for database and working directory?

Things that come to mind:

  1. store everything in the registry (well, did that in MATLAB version and if there is another way, definitely will not go there).
  2. set up another database attached in the jar file to store everything
  3. Is this a so called persistence problem? What are Java Persistence or Java Data Object? Do they have the way to make it working?
  4. any other suggestions?

    Take a look at the Java Preferences API. It is a standard Java SE mechanism for storing preferences that does so in a platform specific, but application neutral way. Uses the Registry on Windows, Preferences files on OS X, and I believe ~/.files on Unix.
