Thank you so much! It was my stupidity. Now the project is up and running. However, it gives me this error:

private Context context = null;
private DataSource datasource = null;

public void init() throws ServletException {
          try {
               context = new InitialContext();
               datasource = (DataSource) context.lookup("java:/comp/env/jdbc/MySqlDS");
          } catch (Exception e) {

I am really new to DataSource but Taste CF engine in Mahout requires a datasource.

The code above gives me the following error:

22:23:53,062 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/_____].[RecommendServlet]] Servlet.service() for servlet RecommendServlet threw exception: java.lang.IllegalArgumentException: dataSource is null or empty

Is something the wrong?
