display iterator in jsp

I have the following code:

@Override  
public Iterator retrieve() throws SQLException {  
    List<PasalBean> pasalObject = new ArrayList<PasalBean>();  
    try {  
        Class.forName(dbDriver); 
        con = DriverManager.getConnection(url);  
        ps = con开发者_如何学Go.createStatement();  
        rs = ps.executeQuery("select * from T_PASAL WHERE ID_PASAL = '" + id_pasal + "' ORDER BY ID_PASAL");  
        while (rs.next()) {  
            pasalObject.add(new  PasalBean(rs.getInt(1), rs.getString(2), rs.getString(3), rs.getString(4)));  
        }  
    }catch (Exception e) {  
        System.out.println("Error Data : " + e.getMessage());  
    }  
    return (Iterator) pasalObject;  
}

How can I display it in JSP?


First, this code will fail. You cannot cast a List to Iterator. Make it return a List.

Then, what you need in order to display it in a servlet is:

request.setAttribute("list", retrieve());
request.getRequestDispatcher("/path/to/jsp").forward();

And then in the JSP:

<c:forEach items="${list}" var="item">
   ${item.somePropertyOfTheBean}
</c:forEach>

It would be good to place the retrieve() method in a separate, data-access class (DAO), and not directly in the servlet.
