My team has recently made the switch to Java from LabVIEW and as such, we need to put Java on the Rio. We successfully did that to one a while ago with no problems. Yesterday, however, we couldn’t get the installation tool to correctly install Java. If we use the .jar web browser as soon as we try to download the proper distribution we get a 401 error (access denied). If we download the .tar directly it will successfully untar but as soon as that finishes the next step fails and we get an Access is denied Exception.
Has there been an update between around St. Louis worlds and now that has broken the installer or have I just forgotten a step somewhere along the way? I’ve tried it on 3 different computers and gone through both ethernet and USB, all with the same result.
To me it sounds like you are either on a restricted internet connection*, or are not signed in as an administrator on the computer, or both. If this is the case, use an unrestricted internet connection as an administrator.
While I wouldn’t rule out the restricted school network (although it worked once they are always changing the blocklist), this was done at home with an unrestricted network connection and logged in as an admin.
I have not tried to re-image the rio yet. When I go to the shop today I will try that, but I don’t imagine that would fix the 401 error from the installer.
Login and accepting the terms works just fine. The problem occurs when I click on the ARMv7 Linux - VFP, SoftFP ABI, Little Endian JRE download link.
Pic 1: Logged in and the terms are accepted. I click on the link at the bottom of the picture.
Pic 2: After a very brief pause on the downloading screen, I get the second picture.
This looks like a network issue. I would make sure you have disabled all firewalls and security software. If that does not work, try a different computer.
While the browser inside the .jar file still isn’t working, we finally got the software to load. The only thing I did differently was open it directly as opposed to through the Windows start menu (I can be dense sometimes) and it found the file it needed automatically.
All traffic was allowed through my firewall and the firewall was disabled and that had no effect on the 401 error.
Thank you all for taking the time to try and help!
