Yes I' m sure.. I created a new package in the examples package where I placed my classes following the paradigm of package cf.taste.example.grouplens.
But even when I try to import the package cf.taste.example.grouplens, I get the same compilation error. Something is going on with the servlet dependencies.. -----Original Message----- From: Sean Owen [mailto:[email protected]] Sent: Friday, May 28, 2010 8:49 AM To: [email protected] Subject: Re: RE: Change Recommender servlet Are you sure your package and import statements are correct? This refers to a package cf.taste.example.movielens but that is not valid. I don't think this is related to the project per se.

Yes you are right. I have actually created a new package named movielens in the examples package and have modified RecommenderServlet to refer to it. By the way, when I import the package in RecommenderServlet class in Eclipse I see no errors. The package is imported ok... >I think you are doing it right, except that the artifactId / module >name is 'mahout-examples' inst... I changed the artifactId name to 'mahout-examples' and Org was a misspelling but not I get the same compilation errors as I described in the first mail. It still cannot see the package... Do you have any ideas how to add the dependency? Perhaps another arfifactID/groupID?
