Back at it some more.
So we went back to Ubuntu 12.10
1. Followed exact apt-get install instructions.
2. Tested Apache - worked
3. Tested Jetty - worked (after editing the /etc/default/jetty file to put Nostart correct
4. Followed exact Get Chronam instructions
5. Followed exact Configure Solr instructions
6. service jetty start command returns Starting Jetty: FAILED
Luckily remembered this time to make copies of original /etc/default/jetty and /etc/init.d/jetty files
7. Replaced "new" /etc/default/jetty with original.
8. Started Jetty - says it started but not correctly
9. Put "new" /etc/default/jetty
10. Replaced "new" /etc/init.d/jetty with original
11. Started Jetty - gives the correct "*Starting Jetty servlet
engine. jetty..." information.
12. Can access jetty in browser
13. Solr fails - "404 Error - Problem accessing /solr. Reason: NOT_FOUND"
I have witnesses that will swear we had this running at one point. We are following the instructions exactly.
We haven't tested here using Ubuntu 13.04 (12.10 only so far), but you should be able to execute these instructions anywhere besides /opt (like in your home directory, or from /opt/chronam). Can you tell us what's in the jetty log? It should be in /opt/solr-4.3.1/logs/ if it was able to write there.
