yep, I'm sorry for my bad way of expressing but I meant that. I give the
connection details to my container through a ressource file and fetch a
dataSource from there which will be given to my constructor/recommender.
The point is that the fetched thing has a type and I meant that this
type would be of the abstract class DataSource.

No. You don't make any DataSource. Your container does, once you've
configured it. You look it up with JNDI (or just use the constructor
that takes the JNDI name -- the Mahout implementation will look it
up.)
There is no workaround here. It all works as intended, as-is. You do
have to understand how to configure a J2EE container to use the output
of taste-web, which is a J2EE .war file.

OK, so I must deploy my container a ressource file where all needed data is
specified to connect to my MySQL server/database. Then I make a dataSource
with an abstract type DataSource which is fetched via JNDI from my ressource
file (I don't know which type it has - e.g. MySQL/PostgreSQL/... because I'm
using an abstract type). This dataSource is given to my constructor and it
should work? (so, it's something like a "workaround" :D )
In fact, I can use the Maven Jetty WebServer too if am able to deploy a
valid ressource file and can include the MySQL Connector/J or I can make mvn
package in the taste-web folder and copy the war file to an other container
(e.g. Tomcat) to work with this file.
