android word解析出错求解！！！

public class MyWordExtractor {

public static void main(String[] args) {
   File file = new File("E:\\test.doc");
   try {
    FileInputStream fis = new FileInputStream(file);
    WordExtractor wordExtractor = new WordExtractor(fis);
    System.out.println("【使用getText()方法提取的Word文件的内容如下所示：】");
    String[] paragraph = wordExtractor.getParagraphText();
    System.out.println("该Word文件共有"+paragraph.length+"段。");
    for(int i=0;i<paragraph.length;i++){
     System.out.println("< 第 "+(i+1)+" 段的内容为 >");
     System.out.println(paragraph[i]);
    }
   } catch (FileNotFoundException e) {
    e.printStackTrace();
   } catch (IOException e) {
   e.printStackTrace();
}
}用poi来解析word此方法仅在PC  eclipse上可以正常运行，但放在android模拟器上运行出错，各种包已导入，不运行不报错，运行时报错：05-07 13:12:57.853: E/dalvikvm(32119): Could not find class 'org.apache.poi.hwpf.extractor.WordExtractor', referenced from method doc.reader.readactivity.onCreate，求指导啊！！！ --------------------编程问答-------------------- 需要的jar没有一起打包吧 --------------------编程问答-------------------- 包中有这个接口的，打开可以看到。 --------------------编程问答--------------------

补充：移动开发 ,  Android
