Solr Recommendester gives "SolrException: Unknown Search Component: Spellcheck on org.apache.solr.core.SolrCore"

I tried using the Solr component Suggester, but it gives an exception Unknown Search Component: spellcheck. I am using solr version 3.6. I made changes to solrconfig.xml, so it looks like

<searchComponent class="solr.SpellCheckComponent" name="suggester">
 <lst name="spellchecker">
      <str name="name">suggester</str>
      <str name="field">name</str>
      <str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
      <str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
      <float name="threshold">0.005</float>
      <str name="buildOnCommit">true</str>
      <str name="spellcheckIndexDir">spellchecker</str>
 </lst> 
</searchComponent>

<requestHandler class="org.apache.solr.handler.component.SearchHandler" name="/suggester">
  <lst name="defaults">
  <str name="spellcheck">true</str>
  <str name="spellcheck.dictionary">suggester</str>
  <str name="spellcheck.count">10</str>
  </lst>
  <arr name="components">
  <str>suggester</str>
  </arr>
</requestHandler>

Now I saved it and started solr, but it gives an error 500. There is a long stack trace that looks like this

HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: <abortOnConfigurationError>false</abortOnConfigurationError> in solr.xml ------------------------------------------------------------- org.apache.solr.common.SolrException: No cores were created, please check the logs for errors at org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:172) at org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:96) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:295) at

and a few more

According to the stack trace, Solr cannot find the component spellcheck, but according to the Solr plug, this component comes with Solr version> 1.4.
