[ubuntu] [SOLVED] Webex not working on Hardy

[HDave]

I recently upgraded from Gutsy to Hardy and somewhere along they way I broke webex.

Whenever I go to start the meeting manager it says 'downloading' and the progress bar goes to 100% and then nothing!

I am using the sun 6 java plugin for firefox. Webex's site says they support Ubuntu 7.04 and Java 1.5 so I should be ok.

Does webex work for anyone else on Hardy? Any suggestions on how to track down the source of this problem?

[HDave]

I'll save everybody the ugly details of 1.5 hours on the phone with webex and a day of experimenting. Suffice to say that the Webex meeting manager is a java app and is launched from firefox without a bash script.

So my .bashrc lines that read:

export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.66
export PATH=$JAVA_HOME/bin:$PATH

didn't work.

Moving these two lines to my .profile did the trick. Webex is back up and running and now I can see people's app shares...NICE.

The Webex folks say have limited support for Ubuntu 7.04, but that they will have 100% full support for Ubuntu with version 8.10. Wish it was sooner, but it's still cool to see a huge commercial company paying us some genuine attention.

As another follow-up, I also found out *why* webex was broken with Java 1.5 on Hardy. Webex requires libstdc++5.

So I reverted BACK to java 1.5 (from Sun) to test out and did a:

sudo aptitude install libstdc++5

and VIOLA it worked. Much easier solution than migrating to Sun Java 6.

I figured this out from examining my JVM log files in ~/.java/deployment/log directory. I was missing these log files until I enabled logging in Java via System->Preferences->Sun Java 5 Plug-in Contol Panel.

The error message in there was:

Exception in thread "Thread-572" java.lang.UnsatisfiedLinkError: /home/dvredenburgh/.webex/824/libatdv.so: libstdc++.so.5: cannot open shared object file: No such file or directory.

Installing the libstdc++5 fixed the problem under Java 6 as well.

Thanks for this recent post; I've been struggling with the WebEx connection since installing 8.04.


I installed jre-1_5_0_15-linux-i586.bin from Java website then ran,

aptitude install libstdc++5

I created a symbolic link in my firefox plugins directory:

ln -s /home/subran/jre1.5.0_15/plugin/i386/ns7/libjavaplugin_oji.so
/usr/lib/firefox-addons/plugins/libjavaplugin_oji.so

and then logged into my webex session. The client downloaded successfully and I was viewing the session - at this point, I don't see the "shared application" from the host working yet...

Same problem here. I complained few months ago to WebEx and they basically didn't reply (I had bugged them before with the poor sound quality... and then they did do something... (propose to upgrade to beta for testing, tja..) finally we do the sound via skype)...
Anyway...
I do have libstdc++5 installed in my system, and I don't see the Exception reported by HDave (I have as well libstdc++6, libstdc++6-4.1-dev, libstdc++6-4.2-dev; do they interfere??).
I can show my desktop to other attendants but I cannot see theirs. The window is white. My mouse clicks are (were, I tried a couple of long ago) transferred to the remote machine if remote control was enabled.

The only error I see in the file HDave reports is:
[jmeetingclient] HandleConferenceResource i=0 Error Happened.
[jmeetingclient] HandleConferenceResource i=1 Error Happened.

googling there was no help for me.

The webex faq says that what's needed is:
* Kernel: 2.4.21 or above
* X Lib: X11R6 or above compatible
* C++ Lib: libstdc++ 5
* Desktop Environment: XFce 4.0 or above, KDE, Ximian, Gnome
* GDK/GTK+ version: 2.0 or above
* Glib: 2.0 or above
* Sun Java 1.5 or above
* OSS Interface (for Audio)
* Firefox 1.5 or higher or Mozilla 1.7 or higher
* JavaScript and cookies need to be enabled
* 56K or faster Internet connection

So I guess I miss some libs from there. Strangely enough it was working on Feisty. I investigated a bit on the GDK/GTK+ and Glib, but I there are many different options there when I do apt-get install glib<TAB><TAB> ... so I don't know what to try. Could you guys report which of those libraries you have installed on your system so I could see the differences?

Any other ideas?

Thanks!

I have libstdc versions 5 & 6 so it can't be that.

Check your "java -version" -- on my system it reports:

java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Server VM (build 1.5.0_15-b04, mixed mode)

Oddly enough it could be a video card & driver issue. Other that this I am out of ideas...sorry.

[lorubenet]

Tja, I have exactly the same java version.

I put as well this lines in .profiles, .bash_profiles and .bashrc with no luck...
There must be a stupid trick I'm missing...
Thanks anyway!

works great for me with hardy heron

i simply edited .profile to reflect:

export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.06
export PATH=$JAVA_HOME/bin:$PATH

and did an

sudo apt-get install libstdc++5

opened firefox 3 from a terminal to avoid logging in to make changes effective and it loaded up immediately. java app used to just hang at 65%

OK issue solved...

I had done everything fine... the only problem left was the version of WebEx our server was using. Now they updated it and it works fine.

Thanks for all your help!
