Apache POI+read Excel file

Cine a lucrat cu Apache POI, pls help.Vreau sa fac un program in java care sa citeasca un fisier Excel, jarul necesar pt program este importat.Este un exemplu destul de simplu, acesta este codul:import org.apache.poi.hssf.usermodel.HSSFCell;import org.apache.poi.hssf.usermodel.HSSFRichTextString;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.poifs.filesystem.POIFSFileSystem;//~--- JDK imports ------------------------------------------------------------import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.IOException;import java.io.InputStream;import java.util.Iterator;/*** This java program is used to read the data from a Excel file and display them* on the console output.** @author dhanago*/public class POIExcelReader{/** Creates a new instance of POIExcelReader */public POIExcelReader (){}/*** This method is used to display the Excel content to command line.** @param xlsPath*/@SuppressWarnings ("unchecked")public void displayFromExcel (String xlsPath){InputStream inputStream = null;try{inputStream = new FileInputStream (xlsPath);}catch (FileNotFoundException e){System.out.println ("File not found in the specified path.");//e.printStackTrace ();}POIFSFileSystem fileSystem = null;try{fileSystem = new POIFSFileSystem (inputStream);HSSFWorkbook workBook = new HSSFWorkbook (fileSystem);HSSFSheet sheet = workBook.getSheetAt (0);Iterator rows = sheet.rowIterator ();while (rows.hasNext ()){HSSFRow row = rows.next ();// display row number in the console.System.out.println ("Row No.: " + row.getRowNum ());// once get a row its time to iterate through cells.Iterator cells = row.cellIterator ();while (cells.hasNext ()){HSSFCell cell = cells.next ();System.out.println ("Cell No.: " + cell.getCellNum ());/* * Now we will get the cell type and display the values * accordingly. */switch (cell.getCellType ()){case HSSFCell.CELL_TYPE_NUMERIC :{// cell type numeric.System.out.println ("Numeric value: " + cell.getNumericCellValue ());break;}case HSSFCell.CELL_TYPE_STRING :{// cell type string.HSSFRichTextString richTextString = cell.getRichStringCellValue ();System.out.println ("String value: " + richTextString.getString ());break;}default :{// types other than String and Numeric.System.out.println ("Type not supported.");break;}}}}}catch (IOException e){e.printStackTrace ();}}/*** The main executable method to test displayFromExcel method.** @param args*/public static void main (String[] args){POIExcelReader poiExample = new POIExcelReader ();String xlsPath = "//Users//Nakig//Documents//workspace//POI//src//qa.xls";poiExample.displayFromExcel (xlsPath);}}Programul se opreste atunci cand creaza HSSFworkbook, si xlsPath are asha forma fiindca lucrez pe MAc.Multumesc anticipat pt ajutorul vostru.Adika nu poate crea HSSFworkbook; insa jarul care contine toate clasele de creare a obiectelor POI.
