    • Method Detail

      • getSubject

        java.lang.String getSubject()
        Returns the license manager's subject as a descriptive string - null is never returned.
        Returns:
        A string which must compare equal to the "subject" property of the LicenseContent JavaBean. Note that this is public information which may be displayed to the user in a wizard or some other form.

      • getPreferences

        java.util.prefs.Preferences getPreferences()
        Returns the preferences node where the encoded licence is stored or should get stored. This method may return null if the license manager is not used to LicenseManager.install(java.io.File) a license or to LicenseManager.verify() an installed license.

        Note that the preferences node should be globally unique; otherwise, another application could overwrite your license key! Thus, it is recommended to follow Sun's guideline of creating globally unique package names by prefixing them with your globally unique Internet domain. You should then put the main class of your application in this package and return its user preferences node. This is because across platforms you will normally only have write access to the user preferences.
