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

public class BookingServlet extends HttpServlet
{
  private Connection connection;
  private Statement query;
      
  //setup database connection and prepare SQL statements
  public void init(ServletConfig config) throws ServletException
  {
    String driverClassName = config.getInitParameter("driverclassname");
    String dbURL = config.getInitParameter("dburl");

    //attempt database connection and create Statement
    try
    {
      //Load the driver class
      Class.forName(driverClassName);
      //get a database connection
      connection = DriverManager.getConnection(dbURL,"","");
      query = connection.createStatement();
    }
        
    //for any exception throw an UnavailableException to indicate that the servlet is not currently available
    catch (Exception exception)
    {
      exception.printStackTrace();
      throw new UnavailableException(exception.getMessage());
    }
  } //end of init method
   
  public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
  {
    doPost(req, res);
  }

  //process booking
  protected void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
  {
    String userid = req.getParameter("userID");
    String dest = req.getParameter("destination");
    String dat = req.getParameter("date");
    String tim = req.getParameter("time");

    String sql = "INSERT INTO Booking VALUES ('"+userid+"','"+dest+"','"+dat+"','"+tim+"')";   

    try
    {
      query.executeUpdate(sql);

      //set userid in request to pass it on to bookingSuccess.jsp
      req.setAttribute("theName", userid);
                     
      //forward request to bookingSuccess.jsp
      req.getRequestDispatcher("/bookingSuccess.jsp").forward(req, res);
      return;
    }   
    catch (Exception exception)
    {
      exception.printStackTrace();
      throw new UnavailableException(exception.getMessage());        
    }
  }

  //close SQL statements and database when servlet terminates
  public void destroy()
  {
    //attemp to close statements and database connection
    try
    {
      query.close();
      connection.close();
    }
        
    //handle database exceptions by returning error to client
    catch(SQLException sqlException)
    {
      sqlException.printStackTrace();

Ko pakai JDK ngan JRE brape?

MulutBecok

untuk CLASSPATH aku refer ke

C:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar

environtment aku dah setup ok dah termasuk JAVA_HOME,CATALINA_HOME

MulutBecok

Aku pakai

j2sdk1.4.2_08

reza

cuba check file servelet tu ada tak?

MulutBecok

servlet.jar yang kat dalam lib tu ke??
kalau yang tu memang ada dalam folder lib tu

reza

erm ....ko ada install application java lain kut? yg tgh kacau. Slalunya "does not exist" kiranya komputer cari tak jumpa ler

ko cuba guna netbean... pastu ko klik kat file tu ....dia redirect ke mana

your class path tu jangan lock kat satu folder aje,

Cuba tukar your classpath settings to this:

CLASSPATH = .;C:\Program Files\Apache Group\Tomcat 4.1\common\lib\servlet.jar

(notice ada tanda noktah and semicolon di depan CLASSPATH path tu)

try and see if it works. and, kalau dah set classpath, kena reboot PC dulu sebelum run semula for best results (although sometimes once dah tukar classpath dah OK dah)
