Compiling and running Lucene/Solr based on github does not seem to work

[Michael Wechner]

Hi

I have cloned the github version of Lucene/Solr yesterday

https://github.com/apache/lucene-solr

and was running

ant compile
ant test

successfully. Also Jetty  seems to startup fine, but when I access

http://localhost:8983/solr/

then I receive


    HTTP ERROR: 503

Problem accessing /solr/. Reason:

    Service Unavailable


Any idea what I might doing wrong?

Thanks

Michael
