[ubuntu 10.04] jdownloader requires sudo to start

I am running JDownloader on my Ubuntu 10.04 machine. JDownloader was installed via Synaptic Package Manager using the **External links are only visible to Support Staff****External links are only visible to Support Staff** lucid main repository.

I can not run JDownloader as a non-root user.

When I type "jdownloader" in the terminal I get:

and then it holds and nothing happens.

When I go "sudo jdownloader" the program starts normally and after the

10 9/26/10 5:01:53 PM - FINER [jd.JDClassLoader(<init>)] -> Look and Feel JAR loaded: /home/jessica/.jdownloader/libs/laf/syntheticaOrangeMetallic.jar

comes

10 9/26/10 12:39:19 AM - INFO [jd.Main(main)] -> init Splash

But I don't want to run JDownloader as root. I am guessing it is some kind of permission problem, but I am quite new to Linux so I have no idea where to start looking.

Can anybody give me a hint or provide a solution?


tia,

You're right. For security reasons it's better not to run jD as root.

I'm not a linux expert, but I've 2 suggestions for you :-

1) If you installed jD with root/su privileges, I would re-install it without root/su privileges.

2) Try to use a theme other than "syntheticaOrangeMetallic" and see what that gives.

remi, thanks for the reply, although it does not really help me.

I installed JDownloader as regular user via the Ubuntu GUI (of course I had to enter the superuser-password to open the Update Manager).

And I set "Synthetica Standard" as style. I guess syntheticaOrangeMetallic.jar is just the *last* theme loaded, and not the *active* one.


Can somebody tell me where in the filesystem "jd.config.DatabaseConnector(<init>)" is trying to load the database from? Maybe it has a permission problem there.


Running JDownloader as root is quite annoying, because the files it downloads and extracts have root ownership and permissions, so I can't move or delete them with my regular user


More hints please?

Use the "chmod" command? See "http://en.wikipedia.org/wiki/Chmod".

Thanks, remi, I am familiar with the chmod command.

My question was where in the system the database is. In other words, I do not know what to chmod or chown.


br,

jule_

The database is in the jD\config folder. What about the recursive (-R) application of chmod?

All the files in my /home/.jdownloader directory were owned by root (and not by my regular user). I did a "sudo chown -R *" on all files, now they are owned by my regular user but I still got the same error when starting jDownloader.

When I "sudo jdownloader" the "database.log" and "database.properties" in the config folder are recreated with the owner root.

Anyways, I uninstalled/purged jdownloader and after a re-install via Synaptic everything works as it should.


-> solved. (edit: how do I add the [solved] prefix to the topic?)

I'm glad you solved it.

Adding a [solved] "tag" is the privilege of a few official jD developers/supporters.
