This AttributeSource does not have the attribute: TermAttribute

[GoogleCodeExporter]

I included PaodingTokeizr into classifier4J to make it supportive for Chinese, 
following this: 
http://www.cnblogs.com/chenying99/archive/2013/07/12/3185379.html

And I got this exception: java.lang.IllegalArgumentException: 

This AttributeSource does not have the attribute 
'org.apache.lucene.analysis.tokenattributes.TermAttribute'.
at org.apache.lucene.util.AttributeSource.getAttribute(AttributeSource.java:265)

    at net.sf.classifier4J.Utilities.getWordFrequency(Utilities.java:77)
    at net.sf.classifier4J.summariser.SimpleSummariser.summarise(SimpleSummariser.java:82)

My version: paoding-analysis-2.0.4-beta, lucene-core-3.0.0

I don't know what attribute the exception refers. Is this about the .properties 
files?

已解决。我看的那个资源写错了一行代码。
这句是错的：TermAttribute termAtt = 
(TermAttribute)ts.getAttribute(TermAttribute.class);
这句是对的：TermAttribute termAtt = 
(TermAttribute)ts.addAttribute(TermAttribute.class);
