Hi

i have a little problem with my raspberry pi2 and jdownloader2

Crash every time

apt-get install openjdk-6-jre
mkdir ~/jdownloader2
cd jdownloader2
wget http://installer.jdownloader.org/JDownloader.jar
java -jar /home/pi/jdownloader2/JDownloader.jar

But every time that i use gui or web interface (myjdownloader), crash when i put in queue some files or i set up something.

Please can help me to have a stable situation?

my report is:

14.10.15 09.35.51to14.10.15 09.08.28 jdlog://7910334739341/

Thanks a lot for the support

When exactly does your rpi crash? on download? on extraction?

Try to use newer java, I guess it is the java version (very old 1.6). Please user newer 1.7 or 1.8

now i have installed

apt-get install oracle-java8-jdk

so when i launch jdownloader i can't see the ui, and i must use the web interface (my.jdownloader.org)

Is normal? isn't possible have the ui with java8 ?

Anyway is more stable without ui but if there is a way to get ui stable is better for me, webinterface is limited

how do you start JD? it has an UI when you start it with existing X11 environment variable

java -jar /home/pi/jdownloader2/JDownloader.jar

i launch this

[Jiaz]

Yes, but does your Terminal have a valid X11 environment variable?
Or maybe you installed headless java?

really, i don't know how to see that

i only install java with it:

apt-get install oracle-java8-jdk
apt-get install oracle-java8-jdk

check if you have an DISPLAY environment variable set
echo $DISPLAY

if i launch it from raspberry terminal in RDP ( desktop remote from my laptop to my raspberry )

pi@raspberrypi ~ $ echo $DISPLAY
:10.0

if i launch it from my putty in windows, i can't see nothing.

pi@raspberrypi ~ $ echo $DISPLAY

the answer is empty, blank space.

Because windows has no X11 running so you cannot start it with GUI
Either you start it via VNC on the Desktop of your RPI or run it without GUI and use MyJDownloader to control it.

infact for me is good start jdownloader in rpi desktop, but i don't know how with java sdk 8.

which command i launch to have the gui?

[Jiaz]

there is no differend command
but you cannot start from a terminal that has no x11. this has nothing to do with java!
when you connect to your rpi via putty from a windows client, that terminal has no X11 available to show any kind of gui.
you need either to login to your rpi desktop via a remote desktop tool (eg vnc) or put JDownloader into autostart of your rpi desktop

this is no java/JDownloader problem. You just try to do something that is not possible

of course, infact i login into rpi with rdp, and i start jd from rpi terminal and not from putty in windows.

i tried to find a way to remove java from rpi and reinstall

I can take a look via teamviewer if you like

i don't know why, but i deleted all java except java 8.

before i installed java 6, no gui, then java 7, no gui, then java 8, no gui.

So i deleted all java except java 8 and now i can launch jdownloader with gui (in rdp, not in x11 of course) but for me is perfect.

Thanks a lot for the special support, i hope to solve one more time when i migrate my SD card.

Anyway i keep in mind your teamviewer support for the future

Thanks a lot
