cannot start solr after adding Analyzer, ClassCaseException error

[xunzhang huang]

Hi, everyone

After I add a Analyzer to solr, there is a exception ClassCaseException
error and solr cannot be started. the detail is:

environment: solr 1.2, jdk 1.6.03, ubuntu linux 7.10, and a chinese analyzer

I add some lines in schema.xml:

<fieldtype name="text_chinese" class="solr.TextField">
            <analyzer   class="net.paoding.analysis.analyzer.PaodingAnalyzer"/>

  </fieldtype>

I tried some different analyzer, but the same exception happened, so I think
it is solr's problem or my configuration has something wrong

Any ideas?

the error message is:
