OpenRadar error

[bugman]

Ah, that's a lot more informative It looks very much like a Java issue, specifically a Gnome-Java integration issue. See the following for some fixes:

i've sent wagnerw a PM of the post with the java error output... hopefully he'll drop by and let us know if we're on the right track in solving this problem...

in the mean time, i've also run some more searches, making sure to include MAC stuff... i'll be updating this post...

several links have said something like this...

Error when exporting (postits etc.) / java.awt.AWTError: Assistive Technology not found:
Try executing something like:

Code: Select all

sed -i 's/^assistive_technologies=/#&/' /etc/java-8-openjdk/accessibility.properties

which appears to be commenting out the assistive_technologies line in that accessibility.properties file... make sure where that file is located in etc/java* before blindly running commands like these... then adjust as needed to point to the right location...

You don't have execute permission on the file. Open a terminal, change to the directory containing your JAR file, and enter (without the quotes) "chmod +x <jarfile>". Then you should be able to execute it.

How do I change directories? I am having this exact same issue, but when I try entering these commands without entering the directory I get "-bash: syntax error near unexpected token `newline' ". I really want to use the act feature, but things keep trying to stop me.

'change directory' --> cd
Asume you are in your home directory and want change into the 'Download' directory thats inside your home.

Code: Select all

$ cd Download

'cd' understands (like all programs) relative and absolute paths.
Asume you are in 'Download' inside your home directory and want to 'Video' located also in your home directory.
There are two ways. First, the absolute path (asume your home is '/home/solarcar'):

Code: Select all

$ cd /home/solarcar/Video

You can recognize a absolut path by the leading slash!
And second the relative path:

Code: Select all

$ cd ../Video

The '..' stays for 'one directory upward'.
If you want anything in your home directory, there is a third method:
The shell interpret the tilde (~) as your home directory. It doesnt matter where you are in your filesystem, you can do:

Code: Select all

$ cd ~/Video

If you want in your home directory back, doesnt matter where you actualy are, use 'cd' without argument.

Code: Select all

$ cd

To see where you are actually in your filesystem, use 'parent working directory'.

Code: Select all

$ pwd
/home/woodstokk

If you want see whats in the actual directory, use 'list'.

Code: Select all

$ ls

If you want see who you are, use 'whoami'.

Code: Select all

$ whoami
woodstokk

Many commands have more or less options. You can show a quick list of options if you use the option '--help' or sometimes the short variant '-h' after the command.

Code: Select all

$ ls --help

If you need more information about a command, use the 'manual page'.

Code: Select all

$ man ls

If you search for a command and you dont know the exactly name, use 'apropos'

Code: Select all

$ apropos flight
fgcom (1)            - VoIP client for the FlightGear radio infrastructure
fgelev (1)           - Compute FlightGear scenery elevation for a given list of points
fgfs (1)             - the FlightGear flight simulator
fgfsrc (5)           - FlightGear command-line options file
fgjs (1)             - FlightGear joystick utility
fgpanel (1)          - FlightGear Flight Simulator Panel Rendering Engine
fgviewer (1)         - An alternative FlightGear viewer application

This is starting to sound like a disk stability issue. Could you scan your disk and check for bad sectors? It's probably not the case, but the errors you see are also no common.

I'm not much of a techie, but I tried everything in the first couple of posts and open radar STILL won't run. Anyhow, I read the post above and I'm am wondering, could this be caused by using too much storage on the disk?

Sincerely,
SolarCar

I think you downloaded the JAR, please don't!

Please download the zip and extract it. Then start the OpenRadar.sh if you are using linux, or the bat file for windows.

The JAR file is meant for people who upgrade their installed OpenRadar to a new version. In that case, simply replace the existing file with the new one
