 所需类库：

poi-3.8-beta5-20111217.jar
poi-scratchpad-3.8-beta5-20111217.jar

可以从http://poi.apache.org/下载。

单独测试没问题，但放到项目里，会报下面的错误，应该是由于类冲突引起的。

Exception in thread "main" java.lang.NoSuchMethodError: org.apache.poi.POIDocument.(Lorg/apache/poi/poifs/filesystem/DirectoryNode;)V
 at org.apache.poi.hwpf.HWPFDocumentCore.(HWPFDocumentCore.java:146)
 at org.apache.poi.hwpf.HWPFDocument.(HWPFDocument.java:218)
 at org.apache.poi.hwpf.HWPFDocument.(HWPFDocument.java:186)
 at cn.ccb.boup.util.poi.OperateWord.readWordCell(OperateWord.java:37)
 at cn.ccb.boup.util.poi.OperateWord.main(OperateWord.java:87)

解决办法是：打开项目的properties->java build path->order and export，发现poi的2个jar包放到了最后，把poi的包移到最上面。问题解决！
