Apache Solr would not start. Keeps throwing the following error

    java -jar example/start.jar 


    java.lang.ClassNotFoundException: org.mortbay.xml.XmlConfiguration

When you're not inside the example dir, you need to specify the path for jetty.home. It may also be a good idea to set the jetty.logs option as well:

java -Djetty.home=example -Djetty.logs=/tmp -Dsolr.solr.home=example/solr -jar example/start.jar

Specify the classpath to solr files with -cp

java -cp <path> -jar example/start.jar

  • For me it also worked when I did `cd /path/to/example` and then invoked solr. – Nifle May 26 '11 at 06:41
  • This hasn't worked for me. Probably because when the `-jar` option is used, the `-cp` option is ignored. Quote from the Java manual for the `-jar` option: "When you use this option, the JAR file is the source of all user classes, and other user class path settings are ignored." – chiborg Jan 10 '12 at 10:53
  • Yes. This is true, You should add the dependencies on your jar Manifest. – Sacx Jan 12 '12 at 07:46

Make sure that you've met the requirements: http://wiki.apache.org/solr/SolrInstall

type: cd /opt/apache-solr-1.3.0/example type: java -jar start.jar http://wiki.apache.org/solr/SolrOnAmazonEC2
