Same thing I'm getting. Shared Apps is looking for "Open+Office" and
without it being installed, you and I get the 404 (missing) error, so
without it Shared Apps apparently takes the dumper and dies. I'd rather
that Shared Apps didn't depend on anything to start. We can add them
easily enough. Thanks, Ric
p/s Most Ubuntu and Debian installs install Libre Office.

Hi Rickie. Many thanks for your answer. I forget to mention that I have Open Office installed. I removed LibreOffice.

Hello Kalogero,

In my case it works without problems and I never saw any Open Office reference in the log.

Thanks a lot Carlos for your answer. It's strange. As I say before I'm a newbie on linux. I purchase a VPS with Ubuntu 14.4 to test X11 apps. I had update OS. Removed Libre Office. Installed Open Office. The sistem is a 64 bit. The java installedi is a sdk-8u5-linux-x64.tar. Perhaps there's something I have to read about requirements for the server. All the best to all.

Hello

I asked for the screenshot because I wanted to see the command. And unless you have a Firefox folder inside /usr/bin the command is bad. This command run as is in command line?

Another thing you should try is 32bit. I run Java 32. In your log it says that cannot find the 64 but version of the file

Regards

Hi Carlos. 
You are right. I solved the problem when I change OS. I hade take a VPS on an other ISP. (The first one have only 64 bit OS that is possible to install). 
Now im running OW on a Ubuntu 32 bit with Java JDK 7 32 bit and X11 applications works fine.
I don't know really the reason for the problem on Ubuntu 64 bit. Perhaps is Xvfb-xremwinr that have a compatibility issue with 64 bit libraries.
Anyway thanks a lot for your help
All the best

Excellent. Now this post is a very good reference for future users with problems with shared apps.

Hello,

After some testing looks like the error is about a missing function in libXfont called fs_register_fpe_functions. In Ubuntu 14 in 32 or 64 the error happens. But in Ubuntu 12 it works regardless is 32 or 64 bits. So despite my previous believe it is indeferent if it is 32 or 64 bits. 

I think the solution to use it in a newer OS, is to recompile the libXfont with --enable-fc and test.

For now it only works in Ubuntu 12

Hello Mohamed,

Well I don't have the instructions documented. As I recall you must use Ubuntu 12, with xorg libraries installed (Just install Firefox) and it should work. I don't have any idea about Solaris. Just post here your errors.
