HTTP Status 404 while trying to run mahout demo
Hi,
I am trying to run the demo at
http://lucene.apache.org/mahout/taste.html#demo. When I try to access the
web application in browser (step 11,
http://localhost:8080/mahout-taste-webapp/RecommenderServlet?userID=1), I
get HTTP 404 error.
Here is the complete error message:
HTTP Status 404 - /mahout-taste-webapp/RecommenderServlet
------------------------------
*type* Status report
*message* */mahout-taste-webapp/RecommenderServlet*
*description* *The requested resource
(/mahout-taste-webapp/RecommenderServlet) is not available.*
------------------------------
Apache Tomcat/6.0.18
Please advice.
Thank you,
Nagu

Thank you very much Sean.
I fixed this problem by following the steps below:
1. I looked at all the current ports in use by the command, netstat -l
2. I found out that tomcat was using the port 8080, the same port Mahout was
trying to open. I was tinkering with Solr before I was playing with Mahout.
3. I went to tomcat and shutdown it down (using shutdown command).
4. I went through the Mahout demo religiously and it worked like a charm.
Thank you again,
Best wishes,
Nagu

Yes, that's the key. It seems that there is already a server running
on port 8080. Check to make sure nothing else is running? perhaps an
old copy of this server?

I noticed that my command in step 10, mvn jetty:run-war, was failed with the
following errors:
