POI操作word2003 ，在初始化HWPFDocuments时报错

[追追追太阳]

public class POItest {
	String filePath = "d:\\test\\poiTest.docx";
	
	public POItest() {
		// TODO Auto-generated constructor stub
		FileInputStream fis = new FileInputStream(new File(filePath));     
        HWPFDocument doc = new HWPFDocument(fis);     
        Range rang = doc.getRange();     
        String text = rang.text();     
        fis.close();
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub		
	}
}

报的错是：The type org.apache.poi.poifs.filesystem.DirectoryNode cannot be resolved. It is indirectly referenced from required .class files
