  1. Dear Sir,

    I’m fan of this way2java website. Please let me know is this note available in PDF format as we are staying in hostel. So there is no wifi or net facility.


  2. Hi sir,

    I have an servlet containing database connection code . I want to read the jdbc connection credential from .properties file.And i have save the file in WEB-INF/classes folder.

    And in servlet i have the code to read the properties file.i.e

    // package custom;

    import javax.servlet.*; import javax.servlet.http.*; import*;
    import java.sql.*; import java.util.*;

    public class CustomServlet extends HttpServlet
    public void service(HttpServletRequest req, HttpServletResponse res) throws
    ServletException, IOException
    System.out.println(“in service()”);
    System.out.println(“at line no 14”);

    ObjectInputStream ois = new ObjectInputStream(req.getInputStream( ));
    ObjectOutputStream oos = new ObjectOutputStream(res.getOutputStream( ) );
    System.out.println(“after application/octet-stream”);// at line 20
    //FileInputStream fis = new FileInputStream(“webapps/ret/WEB-INF/classes/”);
    FileInputStream fis = new FileInputStream(“”);
    Properties p = new Properties();
    String dr = p.getProperty(“driver”);
    String cs = p.getProperty(“url”);
    String usr = p.getProperty(“user_name”);
    String pwd = p.getProperty(“pwd”);
    Connection con = DriverManager.getConnection(cs,usr,pwd);


    The control reaches at line no 20 but it will not reach at this line

    FileInputStream fis = new FileInputStream(“”);

    i don’t know what is wrong with my code.

    Please help me

    with regards
