E / dalvikvm（786）：在android活动中找不到类'org.apache.poi.poifs.filesystem.POIFSFileSystem'

Question

Below is the Code :
//imports
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;
import org.apache.poi.poifs.filesystem.POIFSFileSystem;


        try{
            // Creating Input Stream 
            InputStream myInput = context.getAssets().open(filename);
            POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput);

            // Create a workbook using the File System 
            HSSFWorkbook myWorkBook = new HSSFWorkbook(myFileSystem);

            // Get the first sheet from workbook 
            HSSFSheet mySheet = myWorkBook.getSheetAt(0);

//请你帮我解决它的问题。我已将相应的jar包含在// Eclipse的java Build path库中。

提前致谢

在Java Build Path中订购和导出包含的jar。
