Subject [jira] Commented: (MAHOUT-179) Taste Demo Help
Date Wed, 23 Sep 2009 13:49:16 GMT


Sean Owen commented on MAHOUT-179:

So I just tried this from a clean installation of the project.

I ran into one issue: the web app needs to include uncommons-math as a dependency. I fixed
that and committed my change just now. So, I imagine you perhaps also ran into the same problem
-- did you see a big stack trace on startup? that would cause the server to not respond.

Anyway once that was fixed, I do now get recommendations at:


(I have updated the documentation in SVN to reflect the right path)

Yes, you should find nothing at http://localhost:8080/. It really shouldn't unpack META-INF
but I guess the plugin does. WEB-INF would be hidden indeed as it is never served as files.

Given the above, is it still not working?

> hi there,
> I'm trying to run the taste demo, just downloaded the latest version of mahout. I compile
the whole thing (mvn install) and I create the package. everything runs smoothly, but in the
end it gives me this error:
> Problem accessing /mahout-taste-webapp/RecommenderServlet. Reason:
> i'm not really familiar with this enviroment but maybe the war file might create a library
'mahout-taste-webapp-0.1' instead of 'mahout-taste-webapp'?
> please help me out.
> thanks a lot,
