Unable to deploy Jenkins inside tomcat7 with Engine's non defaultHost

I am using EC2, I would like to deploy Jenkins war file inside Tomcat7 and I would like to access only that jenkins with the EC2's IP.

Here is my excerpt of tomcat7 server.xml configuration:

  <Realm className="org.apache.catalina.realm.LockOutRealm">
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
           resourceName="UserDatabase"/>
  </Realm>
   <Host name="test.example.com" appBase="hosts/hktest" unpackWARs="true" autoDeploy="true" />
   <Host name="example.com" appBase="hosts/hkprod" unpackWARs="true" autoDeploy="true">
    <Alias>http://ift.tt/1udox0a;
   </Host>

  <Host name="localhost" appBase="hosts/jenkins" unpackWARs="true" autoDeploy="true" />
</Engine>

Here is the error I am getting every time I invoked "./catalina.sh run"

java.lang.IllegalStateException: Invalid context ''. Cannot find context in host localhost
