Error while reindexing on Solr - RSolr::Error::Http: RSolr::Error::Http - 400 Bad Request - undefined field type

Question

I have setup Solr 4.4 on Ubuntu server with Tomcat 6 following this link - http://www.arborisoft.com/how-to-install-apache-solr-4-4-on-ubuntu-12-04/ .

Model Activity is indexed using Solr (Ruby on Rails project). While reindexing, I get this error:

RSolr::Error::Http: RSolr::Error::Http - 400 Bad Request
Error: {'responseHeader'=>{'status'=>400,'QTime'=>59},'error'=>{'msg'=>'undefined field type','code'=>400}}

URI: http://localhost:8080/solr/update?wt=ruby
Request Headers: {"Content-Type"=>"text/xml"}
Request Data: "<?xml version=\"1.0\" encoding=\"UTF-8\"?><delete><query>type:Activity</query></delete>"

I'm able to reindex now. schema.xml had this line missing:

<field name="type" stored="false" type="string" multiValued="true" indexed="true"/>
