add CJKTokenizer to solr

[zha jimmy]

hi, all

    I am try to config solr to support chinese tokenize。

    I saw the tips in schema.xml:

   <!-- One can also specify an existing Analyzer class that has a
        default constructor via the class attribute on the analyzer element
   <fieldtype name="text_greek" class="solr.TextField ">
     <analyzer class="org.apache.lucene.analysis.el.GreekAnalyzer"/>
   </fieldType>
   -->

   Then I modified schema.xml

  <fieldtype name="text" class="solr.TextField" positionIncrementGap="100">
     <analyzer>
       <tokenizer class="org.apache.lucene.analysis.cjk.CJKTokenizer "/>
       <filter class="solr.LowerCaseFilterFactory"/>
     </analyzer>
   </fieldtype>:

   When I start the solr there is some error Caused by:
java.lang.ClassNotFoundException:
org.apache.lucene.analysis.cjk.CJKTokenizer.

   I realized that solr do not have the CJK package ,but how can I add it
in?
