Error during installation of openmeetings

[Giuseppe Tofoni]

Hello there,

This my first installation, and I have the following error:

2011-07-09 16:15:29,758 [Launcher:/openmeetings] ERROR org.red5.server.Scope - Could not start scope [WebScope@1ca203 Depth = 1,

The database has been successfully created (with utf8), the user and passord are correct.

Can you help me?
Thanks in advance

I had the same problem.

 

Try this link http://code.google.com/p/openmeetings/wiki/OpenmeetingsEnUbuntu.

 

 It helped me a lot.

Thanks for your post.
I solved the problem this way:

Download the file from http://jdbc.postgresql.org/download.html
JDBC4 Postgresql Driver, Version 9.0-801, in folder openmeetings/webapps/openmeetings/WEB-INF/lib.
I renamed the file in postgresql-9.0 postgresql-8.2-801.jdbc4.jar 504.jdbc2.jar.old-and-file postgresql-9.0 postgresql-9.0-801.jdbc4.jar in 801.jdbc4.jar. Red5 restart the server and everything will be ok.
I tried openmeetings with moodle and created new users properly.

Hi Giuseppe,

yes, we recently updated the Postgres JDBC driver in the SVN too, but its not released as package yet.

# mv postgresql-8.2-504.jdbc2.jar postgresql-8.2-504.jdbc2.jar.old

# mv postgresql-9.0-801.jdbc4.jar postgresql-8.2-504.jdbc2.jar
