Setup of 0.8-dev for bbb-web failed

[dalal najem]

Hi BBB Team,

i guess i need some help. I try to prepare my  0.7 VM in order to work with the current 0.8-dev master branch which bring me some headaches. The VM was working fine as a bbb-client development environment even for 0.71a. Now i have to switch completly to the latest master branch alias 0.8-beta (revision from the 8th august).

1) I got the bbb-client compiling fine with ant as well as flex builder, very fine.
2) To build the current bbb-web and let it working with bbb-client, i followed mainly the instructions on:

http://code.google.com/p/bigbluebutton/wiki/DevelopingBBB#Working_with_BigBlueButton_Web_-_The_API_part_of_BBB

3) Unfortunately gradle and grails were not installed in VM by default as mentionend in the documentation, so i installed grails 1.1.1 and gradle 0.9.2. That went fine.
4) The latest step i stuck in is the 'ant' of bbb-web. It seems some packages can't be imported like google.gson. The google.gson is only one of several errors all related to missing packages. Is this package intended to be shipped with BBB or do i need to install it otherwise? Or do i miss a path specification? Maybe the problem arrives from using the 0.7-VM and not the newest 0.71a-VM?

The output of the build is as follows:

firstuser@bbb-vm-20100905-08:~/dev/bigbluebutton/bigbluebutton-web$ ant

Hi Dalal,

We'll be updating the instructions for setting up the development
environment for BigBlueButton shorty.

http://code.google.com/p/bigbluebutton/wiki/DevelopingBBB

We're just working on getting a beta of BigBlueButton 0.8 ready. If
you can wait a bit longer, we'll have the instructions updated and
tested and save you some effort.

Regards,... Fred

Hi Fred,

thats good to hear and i appreciate your effort to fix the
documentation. Unfortunately i am little bit in hurry, due my client
has a fixed webinar meeting at the end of this week. So if you could
just give me a hint about that problem with the missing packages i
would be very very thankful to you!

Greets!

[Richard Alam]

Try doing gradle resolve jnder bbb-web to downlosd the dependencies. See build.gradle for the correct command.

Thanks Richard!

'gradle resolveDeps' did the job after i built bigbluebutton-common-messages-0.8.jar and copied it to ~/dev/repo/

After that i cleaned and built bigbluebutton-web successfully. When restarting the tomcat with the new war i created the demo meeting successfully (catalina.log) and the client (0.8-dev) returned:

The connection to the server has been closed.

Fortunately the Log Window button didn't appear, so i can't see in the clients log window whats going on. I guess thats when the preloader finished and the modules are initilized.

Logs in tomcat dont say anything, after the join and redirect to the client.

Any ideas what to do?

This error mean that Red5 is rejecting the connection. You can take a
look at /usr/share/red5/log/error.log or
/usr/share/red5/log/bigbluebutton.log
for clues. Try tail-ing the log file while you try to login to get a
clearer view on what is happening.

Thanks, that helped a step further...

After stopping red5, gradle war deploy, restarting red5 i got a server rejection error message:

The connection to the server has been rejected.

red5.log says:

INFO  o.red5.server.net.rtmp.RTMPHandler - Connecting to: [WebScope@f90137 Depth = 1, Path = '/default', Name = 'video']
INFO  o.red5.server.net.rtmp.RTMPHandler - Scope bigbluebutton/room-mock-default not found on 192.168.1.250

one thing i noticed is the mock config, i switched it to production value (host="http://192.168.1.250/bigbluebutton/api/enter"), but still similar result:

INFO  o.red5.server.net.rtmp.RTMPHandler - Connecting to: [WebScope@f90137 Depth = 1, Path = '/default', Name = 'video']

One hint to those who maybe know, when starting red5 with console output, i see this errors:

Error creating bean with name 'web.scope' defined in ServletContext resource [/WEB-INF/red5-web.xml]: Cannot resolve reference to bean 'web.handler' while setting bean property 'handler';

Anything new in 0.8 thats needs to be handled differently than for 0.71a? Do i need to modify /WEB-INF/red5-web.xml?

Thanks for any hint!

[dalal najem]

I forgot: at the end of the red5 server output from the console:

APPSCOPE is NOT NULL!!!!

How are you starting the client? Seems like you are starting from
FlexBuilder? It's trying to connect to room-mock-default.
What's the contents of config.xml? Looks like you are loading join-mock.xml.

Actually i can build the client from flexbuilder as well as from command line. Currently i build the client from current master with ant successfully and start the session via the Demo Page, without launching from FlexBuilder.

This is what bbb-conf --watch has to say:

I would like to understand how it comes that the client returns "connection rejected"? Whats the net test behind that message? Testing video connection to asterisk? Asterisks log is quite empty. Firebug tells me, that the client joined the room successfully (192.168.1.250/bigbluebutton/api/enter):

<returncode>SUCCESS</returncode>

I was switching between mock-room and normal production setting, both the same result. Here my config:

<config>
    <localeversion>0.8</localeversion>
    <version>3818-2011-01-18</version>
    <help url="http://192.168.1.250/help.html"/>
