Key: MAHOUT-611
URL: https://issues.apache.org/jira/browse/MAHOUT-611
Project: Mahout
Issue Type: Improvement
Affects Versions: 0.5
Environment: Mahout Hackathon (CBase Berlin):
Mac OS X 10.6.6
$ java -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04-307-10M3261)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-307, mixed mode)
$ mvn -version
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.6.0_22
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.6.6" arch: "x86_64" Family: "mac"
Reporter: Manuel Blechschmidt
Priority: Trivial
When trying to start the integrated jetty server in taste-web it can not load
the class: "${recommender.class}". When checking out trunk it should be
possible to directly start up the taste-web application with: mvn jetty:run
