edit: sry, tomcat is already installed because otherwise the taste-web
examples wouldn't work... :)

ok, so I must install tomcat too and write an extra application for
tomcat to realise a standalone server to handle SOAP request handling?
Wouldn't that be nonsense because "taste-web" does the same?
I'm sorry but maybe I have a simple problem understanding the purpose
of the "taste-web" thing because the provided grouplens example works
too if I copy the compiled jar file into the lib directory and so on.
Because of that I thought it would be the same - just edit the
grouplens example to use MySQLDataModel instead of FileDataModel,
compile it, make a jar, copy it into the same directory and run mvn
package; then run mvn jetty:run-war and everything should work. In
fact, I can't compile my source files because they need mahout core
and MySQL Connector/J (to provide a dataSource).
I'm really confused now...
Quote from the source you provided me - that's what I meant that I want:
"
Standalone server
A Mahout recommender can also be run as an external server, which may
be the only option for non-Java applications. It can be exposed as a
web application
via{{org.apach.mahout.cf.taste.web.RecommenderServlet}}, and your
application can then access recommendations via simple HTTP requests
and response, or as a full-fledged SOAP web service. See above, and
see the javadoc for details.
To deploy your Recommender as an external server:
* Obtain a copy of the Mahout distribution, either from SVN or as a
downloaded archive.
* Create an implementation of
org.apache.mahout.cf.taste.recommender.Recommender (must have a
no-arg constructor).
* Compile it and create a JAR file containing your implementation.
* Navigate to the directory where you unpacked the Mahout
distribution, and navigate to{{trunk}}.
* Run{{mvn install}}, which builds and installs Mahout core to your
local repository
* cd taste-web
* Copy your .jar file: cp [your .jar file] ./lib
* Edit recommender.properties and fill in the recommender.class with
your Recommender clas: recommender.class=[your recommender class]
* mvn package
* Your .war file is now available in the build directory as
mahout-taste-webapp.war (which can be renamed).
", but as I told you before, I can't compile my implementation - or
better my variation of the grouplens example - of the taste
recommender...

Nope, it is something you deploy in your container like Tomcat. It's
nothing to do with Mahout or your web app directly.
MySQLDataModel does not depend on MySQL Connector directly, so you do
not need this dependency. It is simply an implementation which uses
MySQL-friendly SQL syntax.

Ok, so if I understand that correctly, I must copy the MySQL
Connector/J
into<mahout>/taste-web/lib, then make a mvn package and the connector
should work? But the problem is my recommender class. For test
purposes I
just edited the grouplens example to make a MySQLDataModel instead of a
FileDataModel but I can't compile this file because of the unsolved
dependencies (mahout deps on my local environment via Eclipse, or MySQL
Connector deps on my server (e.g. with overwriting the grouplens
examples
and compile the examples again)). Do you know a way to compile those
source
files without the need of those deps (it's a never ending circle :) )?
