Aby's specific problem seems to be resolved, but in case someone else stumbles onto this page with the same problem I had...

Make sure that your /opt/solr directory has the correct permissions set. I was following the SolrJetty tutorial before later moving to the Tomcat install. Because my solr user was created with this command:

useradd -d /opt/solr -s /sbin/false solr

the /opt/solr directory was created with permissions 700, so tomcat could not get to the WAR file. Change to 755 and it worked perfectly.
