I installed BBB 0.81, and built the bigbluebutton-client like in the tutorial, and when I try to connect it gets stuck at: "Connectig to the server ......."
And I get the following error:

/var/lib/tomcat6/logs/catalina.out:2014-09-18 16:09:20,459 ERROR [org.codehaus.groovy.grails.web.context.GrailsContextLoader] - <Error occurred shutting down plug-in manager: org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (File input/output error prodDb.properties java.io.FileNotFoundException: prodDb.properties.new (Permission denied))>

Is there a config file for a database connection? Because I can't find it.

If I set the client back to the original source (/var/www/bigbluebutton/client) it works fine.

Any ideas?

Hi Alex,

Check out

https://code.google.com/p/bigbluebutton/wiki/Developing#Setting_up_the_environment

Specifically

The config.xml file tells the BigBlueButton client what modules are retrieved and how to connect to the server. Later on, when you deploy your modified client to the BigBlueButton server, there will be two clients: your modified client and the default packaged client (again, this is good as you can switch back and forth). However, the BigBlueButton configuration command sudo bbb-conf only modifies the packaged client. If you need to change your config.xml (such as when the IP address of your server changes), you need to do it manually.

Regards,... Fred

I know I have to manually change the config.xml, but from the error I think it is trying to connect to a database, specifically to read form a file prodDb or something. In my config.xml I don't see nothing about any database. Can you tell me where is this file, or what part of the BBB is trying to connect to a db?

Hi Alex,

> I think it is trying to connect to a database, specifically to read form a file prodDb or something

There is no database in BigBlueButton. We think these messages come from the grails application which is expecting to connect to a database.

As as aside, we did look into how to disable these messages -- or at least set the appropriate configuration in bbb-web so it doesn't try to create one -- but we didn't find the solution.

For now, you can ignore these messages. We've see them as well on our servers.

Well, the problem is that when I launch the app (using my compiled version of bbb-client) it gets stuck at: "Connectig to server ...."

What am I missing out? Why it doesn't connect? Can you point me into the right direction?

Hi Alex,

If the only changes you've made are to the client, then the problem isn't with bbb-web.

It's possible your browser is caching some components of the older client -- try clearing your cache or switching browsers.

Also, double-check that the config.xml being loaded by the BigBlueButton client is pointing to the correct hostname/IP address. You can verify this by loading it directly in your browser

http://hostname/client/conf/config.xml

Regards,... Fred

I didn't made any modification to the client: just cloned the repo, compiled and tried to run the app. When trying to join the meeting it gets stuck at: Connectig to server...

When I switch back to the default bbb-client (the one from /var/www/bigblueclient) it works fine.

The ip's in bbb-client-dev (from config.xml) are ok. Is there smth else I have to modify?

> Connectig to server...

The client is trying to connect to the BigBlueButton server using the URLs in the config.xml.

> The ip's in bbb-client-dev (from config.xml) are ok.

Can you compare the config.xml in your development folder with the config.xml at

/var/www/bigbluebutton/client/conf/config.xml

and ensure they match. Also, verify that your getting the same config.xml in your browser as well.

Also, did you get any errors in compiling the client?

Regards,... Fred

I found that in my config.xml after every module I had smth like this: ChatModule.swf?v=VERSION, and I replaced VERSION with the number found in the normal bbb-client which was 4359. Where is this number taken from?

Besides that there is no difference between config's.

I don't have errors, just a few warnings, but they seem ok to me:

Hi,

You installed 0.81 but compiling the upcoming 0.9.0 client. I believe you are compiling the master branch instead of the

0.81 release branch (https://github.com/bigbluebutton/bigbluebutton/commits/v0.81-release)

As mentioned on this section (https://code.google.com/p/bigbluebutton/wiki/DevelopingBBB#Checking_out_the_Source) you need to checkout the

0.81 branch.

git checkout -b my-bbb-branch v0.81-release

Then "ant && ant locales"
