Jdownloader doesn't start

[Tassadar]

Hi all,

I'm using kubuntu 13.04 x64 and I'm trying to install jdownloader.

My stepts have been:

Install Java

sudo apt-get install openjdk-7-jdk openjdk-7-jre

Download and install jdownloader:

wget http://installer.jdownloader.org/jd_unix_0_9.sh
sudo chmod +x jd_unix_0_9.sh
sudo bash ./jd_unix_0_9.sh

Then jdownloader starts ok and works, update himself and all this stuff.

The problem comes when I restart, then if i try to run jdownloader it seems to be loading for a moment but nothing, and if i try to run the updater I get this error:

java.lang.NoClassDefFoundError: jd/gui/UserIO

Why not install from the ppa ? I tried it and it works fine

sudo add-apt-repository ppa:jd-team/jdownloader
sudo apt-get update
sudo apt-get install jdownloader-installer jdownloader

uget and fatrat are also good download managers.

Many thanks silver_moon,

I've install using this procedure and the first time I open JD I get this message (it also happened to me before):

A new Java version has been released recently. We discovered that upgrading previous java versions > to java 1.6.0_26 will cause your JDownloader download list to dissapear.

So if you are planning to upgrade to java 1.6.0_26 > first complete your downloads. empty your list, and only then continue with the java update. After the upgrade is done you can continue adding new links to your JDownloader safely.

If I press read more it takes me to this web: LINK

I've not update java since I don't know how to, but not Jdownloader works after restarting

Would it be adviceable upgrading Java?? How can i??

Many thanks!

you can upgrade java later I guess, first try installing jdownloader and see if it works.

The question is: Is adviceable upgrading java? If so, how to do it?

Many thanks for all
