Hi,
I am new developer using OpenCms. While I am going in database setup
wizard for MySql which is running on the other server then following
error is displayed.

   It was not possible to create a database connection with the given
parameters.
Please check the Exception below. There can be two reasons for this
error: 
      * Your database is down, or
      * Your database is not accessible with the given connection
        parameters.
Be also aware that Alkacon recommends to use the following JDBC drivers
for MySQL 4.1.x & 5.0.x:
[mysql-connector-java-5.0.7-bin.jar]

Check that the Jdbc drivers are included in your class path. 

   
Error connecting to database using: "jdbc:mysql://192.168.0.7:3306/".
