Hi,
Can anyone assist Aysha with his Windows 7 install ? What can cause the error; Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up. He states that he can access the OpenMeetings database from the command line, so I cannot think what might be causing this. Is it normal for a Windows install to be connecting through “mysql-connector-java-5.1.23-bin.jar:na”, this is not in my logs for Debian installation, naturally.
