For example, a careless employee (or a disgruntled one) could wipe out all other user's preferences in one stroke. Typically files under /etc are not world writable as users changing other's user's setting is then possible, and considered a type of security breach of the user's expected environment. JRE allows some applications written in the Java programming language to launch via some browsers. If your want any user to read any other user's preferences (the description sounds like you might) then you will need to have an installer that runs as a sufficiently authorized user (typically root) to make the required directory under /etc and change it's permissions to be world writeable. Java Runtime Environment is often referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on, or Java download. Which will place them in hidden directories just off their home directory (where they will have modification privileges). This means that for users to have access to Preferences, they should go under erRoot() Typically such files are protected against modification by not being world (or even most user) writeable. Apparently something in the Java code defers to the specification of the operating system over your decision to re-base the preference root. Odds are your define is ineffective in a Linux system because it fails to start at /etc. ![]() Any non-system preferences can go in other locations, but it is a violation of the design of the operating system to have system preference go elsewhere. This is due to history, and is a standard that is regulated by the Linux Standard Base. In a Linux system, the System root preference node will be under /etc. So I'm assuming that tProperty isn't working. The only place where you can see it is System Preferences. WARNING Couldn't flush system prefs: : /etc/.java/.systemPrefs/usr create failed. Free Download Video Guide: How to uninstall Java on a Mac Remove Java from Mac Manually Java is not a standard application, so it does not appear either in the Launchpad or in the Applications folders. When I execute my program, I get the following WARNING: Turn Location Services on or off for each app in the list on the right. (You may need to scroll down.) Open Privacy & Security settings for me. systemPrefs folder before execute this command line and its implicit that systemRoot() will use it. On your Mac, choose Apple menu > System Settings, click Privacy & Security in the sidebar, then click Location Services on the right. Preferences pref = Preferences.systemRoot().node("/usr/share/myfolder") Īccording to this site, I have to create. Here's my code: tProperty("java ", "/usr/share/myfolder") So, I'm trying to redirect systemRoot default directory to /usr/share at runtime. I want to use a directory that other of our apps already uses: /usr/share/. So I was studying about and using systemRoot() works fine to me on Windows, saving data at Register.īut I'm really facing some problems on Linux (Ubuntu). I need to create a persistent storage in my Java app so all users can access it.
