No X11 DISPLAY variable set

[bubbaloo]

Hi!

I am trying to run the Subsonic app on my Debian Lenny server.
I downloaded the 3.4 standalone version.
I set the parametres in the "subsonic.sh" to fit the installation.
I have java-common, sun-java6-bin and sun-java6-jre installed.

I tried to start it on my Ubuntu 8.04 desktop install, using "sudo subsonic.sh".
That worked.
Then I logged as root (su -) and tried to run "subsonic.sh".
I got the same error as on my server.

Neither the server (Lenny) nor the desktop (Hardy) have Tomcat installed.

Is it at all possible to run Subsonic on a server without running the Xwindow server ? I do not need/want the X server running. I am low on resources (CPU, RAM) as is.

Thanks for your help in advance!

Here is the complete error message:

I have the same question. I tried to start Subsonic from a Debian startup script but it fails to start, and I think the reason is that DISPLAY is not set.

So is there a way Subsonic stand-alone version can be run without X server?
(Hmm, wonder why java GUI classes are needed for a non-GUI application?)

Thanks to Sindre for a great app!

Can you please try to add the following to the last line in subsonic.sh:

Code: Select all

-Djava.awt.headless=true

Please let me know if it works, then I can add it permanently to the script.

Thanks!
Sindre

Thanks for the reply!

I tried:
$JAVA_HOME/bin/java -Xmx${MAX_MEMORY}m -Dsubsonic.home=${SUBSONIC_HOME} -Dsubsonic.port=${SUBSONIC_PORT} \
-Dsubsonic.contextPath=${SUBSONIC_CONTEXT_PATH} -Djava.awt.headless=true -jar subsonic-booter-jar-with-dependencies.jar

and got:

Code: Select all

Let's see what bubbaloo gets.

Ok, thanks for the quick reply.

I think I know what the problem is, and I'll fix it in the next release.

Until then, the Subsonic standalone version requires an X server.

Cheers,

Let's see what bubbaloo gets.

After a short beauty sleep (believe that at your own discretion ) Bubbaloo got the same result.

I think I know what the problem is, and I'll fix it in the next release.

I am eagerly awaiting the new release.
Have you got any insider info on when we might expect it ?

And thank you for your quick reply on both counts.

Hi bubbaloo,
I think I have enough new features/bug fixes to justify a new beta release within a few weeks. It all depends on wife and children, I guess

Hi. I was just looking at subsonic and it I got this error with the standalone on Ubuntu 8.04 without X installed:
(.:32010): Gtk-WARNING **: cannot open display:


You say that the standalone will require X-server for now (not anything under requirements on the webpage); will the WAR-version need x-server?

I've got a mini-itx running as my homemade gateway/router at home and would be nice to access my music "on the road" without a X-server installed on it.

[sindre_mehus]

No. I'm quite confident that the war version doesn't require an X11 server. (But I haven't tested it).

Thank you Sindre for a quick reply, but it looks like tomcat is as huge as I seem to remember.. I dont think i will run it on my frontend without proper knowledge to secure it

I'll be looking forward to the standalone without X requirements!
