Hi everyone!

Im wanna share my problem with you, hoping someone could help me:


First of all, I use Moodle 1.9; and I have a BBB server, that is working fine (I can access to BBB Server from my browser, using the different API's...). My BBB Server is 0.71a.

 

So, Ive tried to relate Moodle with BigBlueButton. For this, ive already used three diferent modules:

-Module from Dual Code

-Module from Blind Side

-BigBlueButtonBN

 

What do I need? I need a module that, integrated in my Moodle, allows me to create activities in the different courses I got, with differences between "teachers" and "students" (different roles).

With Dual Code Module, it works fine, but every activity that I create, is "the same": no roles, everyone is moderator. So, everyone can change the expositor (everyone could make a presentation!). Thats something I cant allow.

With Blind Side module, it doesnt work. When I try to access, i just can see a page with "Logging in as a moderatori", like its loading. But nothing happens (its still loading from several hours; I guess if it works, its gonna be different). Ive activated the PHP errors, and on that page (while is "loading"), the message I can read is:

Warning: SimpleXMLElement::__construct(): Entity: line 6: parser error : Opening and ending tag mismatch: hr line 5 and body in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): ^ in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): Entity: line 7: parser error : Opening and ending tag mismatch: body line 3 and html in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): ^ in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): Entity: line 8: parser error : Premature end of data in tag html line 1 in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Warning: SimpleXMLElement::__construct(): ^ in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42 Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php:42 Stack trace: #0 /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php(42): SimpleXMLElement->__construct('??<...') #1 /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php(277): bbb_wrap_simplexml_load_file('87.106.251.182/...') #2 /var/www/moodle/mod/bigbluebutton/view.php(102): BigBlueButton::createMeetingArray('this online ses...', 'fb26fe52ed0ae3c...', '', '9ea5119efca11ea...', 'a9a4e04718112af...', '5dbdef9952a1685...', '87.106.251.182/', 'http://87.106.2...') #3 {main} thrown in /var/www/moodle/mod/bigbluebutton/bbb_api/bbb_api.php on line 42

 

And with the third module, BigBlueButtonBN, I made the installation on Moodle 2.0 (because I think its not able to run over 1.9); and, when I try to access to an activity of BBB, it shows me an error message:

Exception: String could not be parsed as XML

 

 

So, as you can see people, I need your help.

Is it possible to run Moodle 1.9 + BigBlueButton 0.71a with any module of BBB?

What about the mistakes? Does anyone know how I can solve them? (or only one! With one module its enough!)

Is it possible to create with a BBB module in Moodle, an activity that students can participate like students? (no moderator role).

Thank you very much for your attention. I'll be around here waiting for your answer smile

Thanks again,

Ignacio.

Hi Ignacio,

The problems you are hitting with BigBlueButtonBN on Moodle 2.0+ are very likely an incorrect URL in the settings panel.

If you try BigBlueButtonBN with the default serer, you'll notice the URL reads

   http://test-install.blindsidenetworks.com/bigbluebutton/

and the help text reads: "The URL of your BigBlueButton serer must end with '/bigbluebutton/'.

The errors you are receiving suggest the activity module isn't able to parse an XML reply from the BigBlueButton server.  This occurs when you omit the '/bigbluebutton/' from the end of the URL.

Can you double-check the URL you gave in the settings panel and let us know the result.

 

> Is it possible to create with a BBB module in Moodle, an activity that students can participate like students? (no moderator role).

 

Yes.  If you leave unchecked the '[  ]  Students must wait until a moderator joins' option in when adding the activity link, the students can join and use the session without waiting for a teacher to join.

Hi Fred,

Thank you so much for your answer! Now its done! I was setting the module like the Dual Code module, and that one doesnt need the "http://" and the "/bigbluebutton/".

During several days I was searching solutions, and finally, I could solve it with an easy change.

Thank you so much for your help!

Ignacio.

You can use the Blindside Networks Moodle integration (bigbluebuttonbn) with any BigBlueButton server. However I would suggest you to use 0.80 since this one has a number of improvements in functionality and quality in comparission to the previous 0.71 that you might want to use.

Hello

we just set up a trial of the big blue button and put on the 'dual code' moodle module for Moodle 1.9 and I get the opposite problem. Everyone is an attendee and no one is presenter. If I click the moderator I get an xml issue.

Although that said I have bizarrely just discovered that if I open it once as an attendee and then flick back to the Moodle page (I have it set to open in a new window) I can then hit the log in as Moderator and suddenly I have the presenter tools.

Just a little bit odd.

I am an administrator on Moodle and do wonder if it is picking something up from the Moodle role.

Regards

Heather

As it has been said few posts ago (scroll up) the first suggestion is always try the defaults. Url http://test-install.blindsidenetworks.com/bigbluebutton/ and Salt 8cd8ef52e8e101574e400365b55e11a6

If that works, you are probably missing the last backslash in your url.

If that doesnt work, your problem is the bigbluebutton server. For some reason you are not receiving the XML response expected by the plugin

Cheers,

Not at all. BigBlueButton can provide its services to any number of external applications. The limit is going to be the capacity of your server.

Do you have a proxy server configured for your Moodle? The version of this plugin for Moodle 1.9 doesn't support proxy, only the 2.x

As I said before, the plugin is not receiving the proper xml response either because the BigBlueButton is not working fine or because there is something in the middle that is breaking the xml.

Well, i'm using the moodle 2.0. So i believe that the problem it isn't with the proxy.

If i  install the BigBlueButton in some server, will is the problem continue ? 

I'm afraid make the installation in a server and this problem continue, and also i already tried to install all moodle again and after install the BigBlueButton but didnt' fix the problem.

Oh well, you are posting in the thread for Moodle 1.9, and due you said you had followed all suggestions in the previous posts and beacuse you never mentioned the versions you have, I assumed the rest. It is always a good idea to provide all the details when asking for help. 

On the other hand, I am sorry I ran out of ideas, I don't know what else you can do if your Bigbluebutton server is working fine and your moodle server too.

Last suggestion I can give you is you should always make sure your integration is working fine with the defaults. After that you can move forward to the next step.

Good luck
