Issue setting up solr multi-core using apache tomcat 7 on windows 8

[ravi koshal]

Hi,
   
I was trying to do multi core setup in solr using apache tomcat 7 on windows 8. The solr home opens up , but no cores appear. I checked the logging section and there was the following error:

 org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error Instantiating SearchComponent, solr.clustering.ClusteringComponent failed to instantiate org.apache.solr.handler.component.SearchComponent

 The stack trace is as follows:

my solr.xml is as follows :

<solr persistent="true">


  <cores adminPath="/admin/cores">
    <core name="core0" instanceDir="core0"/>
    <core name="core1" instanceDir="core1"/>
 
  </cores>
 
 
</solr>

I have added all the jar files (including the solr-core*.jar which has the searchcomponent class.)

my slorconfig.xml in the conf folder of the core is attached herewith.
