public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

//System.out.println(this.getServletContext().getRealPath ("/"));

try{

Workbook wb = Workbook.getWorkbook(

new File(this.getServletContext().getRealPath ("/")+"data.xls"));

System.out.println("2222222");

List<Data> data = new ArrayList<Data>();

for(int i=1;i<wb.getSheet(0).getRows();i++){

Cell[] cell = wb.getSheet(0).getRow(i);

data.add(new Data(cell[0].getContents(),cell[1].getContents(),cell[2].getContents()));                

System.out.println(cell[1].getContents());          

}

wb.close();

request.setAttribute("data", data);

request.getRequestDispatcher("../index.jsp").forward(request, response);

}catch(Exception e){

e.printStackTrace();

}

}

Data.java

 


public class Data {

private String id;

private String name;

private String password;

public Data() {

super();

// TODO Auto-generated constructor stub

}

public Data(String id, String name, String password) {

super();

this.id = id;

this.name = name;

this.password = password;

}

public String getId() {

return id;

<%

List<Data> data = new ArrayList<Data>();

data=(List<Data>)request.getAttribute("data");

if(data!=null&&data.size()>0)

for(Data d:data){
