I just installed Mahout on my windows machine and wanted to try out
the taste example with the grouplens data. Although I seem to have
done everything according to the suggested instructions at http://lucene.apache.org/mahout/taste.html#demo
- However, I cannot get the webapp running and get a 503 message:
Service unavailable. When starting jetty, the servlet Container
accompanying the demo, it goes through and boasts that it started
Jetty Server, but during startup it lets me know that there is an
exception, which I suppose will be the culprit.
java.net.URISyntaxException: Illegal character in path at index 18:
file:/C:/Dokumente und Einstellungen/bda/.m2/repository/org/mortbay/
jetty/jetty-maven-plugin/7.0.0.1beta3/jetty-maven-
plugin-7.0.0.1beta3.jar

...
Etc.
The complete log of the startup process can be found further down. I
would guess that empty spaces might pose a problem, but I am not
sure what I can do about that when the home directory of a user is
used which is always filed under c:\dokumente und Einstellungen\ and
maven goes to look there.
Any Idea where I can change the path, in case that this is indeed
the problem? Otherwise, what is my problem? ;-)
Thanks a lot,
Benjamin
