In the bundle that creates the DataSource you have to have an
Import-Package statement in the Manifest for each package you use.
So at least com.mysql.jdbc.optional and javax.sql.DataSource. It is
quite hard to do that by hand. If you use maven to build your bundle then
you should use the maven bundle plugin which analyzes your java code and
creates the necessary statements for the Manifest.
In this tutorial I describe how to do it:

The tutorial is about karaf but the bundle creation is the same if you
use pure felix. Only the deployment may be different.

I'm struggling with this exception of
Apache java.lang.NoClassDefFoundError:
com/mysql/jdbc/jdbc2/optional/MysqlDataSource. Because I have the MySQL
Connect/J bundle running in Apache Felix. Sometimes I have another
exception, java.lang.NoClassDefFoundError: javax/sql/DataSource, and I
don't know why :(

The solution described by Neil should allow that and should be easy to
implement. Using the service to connect your other bundles to the
datasource even makes them
very indepentent of the implementation of the "bridge bundle". A user
bundle could import the DataSource from my solution with blueprint or the
handwritten java bridge bundle
and would not have to be changed in any way.
What exactly are you struggling with?

What I want it's only a bundle that work as a bridge to whatever
database.
The other bundles access to this one to retrieve any information from
external databases. But I don't get this :(

What you probably want in the long run is a datasource-generating
service, to which you pass the database URI. You can put things in
the properties of the service to indicate whether it's Oracle, mySQL,
MSSQL, etc., so that you can have multiple generating services at the
same time.
