: Thanks for your suggestions. I have now tried installing Solr on two : different machines. On one machine I installed the Ubuntu solr-tomcat5.5 : package, and on the other I simply dropped "solr.war" : into /var/lib/tomcat5.5/webapps
This may be a silly question, but did you create a "solr home" directory (containing your config files and where Solr will put the index you build) and use one of the various methods to tell Solr where that directory is? You can use the example/solr/ directory that comes with the solr releases, but you need to tell tomcat to use it, iether using a system property, or JNDI, or by making it be "./solr/" relative the tomcat working directory. : The full error message is attached. what gets logged before that? what gets logged after that? all of the log info from when you startup tomcat would be helpful. -Hoss
