package does not exist

[sylvia greene]

I am using Tomcat Server. In the webapps directory I have created following directories
webapps / shopping / WEB-INF / classes / shopping
webapps / shopping / WEB-INF / classes / servlet

I have created a bean CD.java in shopping directory and it compiles fine

CD.java

  
package shopping;
public class CD {
  String album;
  String artist;
  String country;
  float price;
  int quantity;
  public CD() {
    album="";
    artist="";
    country="";
    price=0;
    quantity=0;
  }
  public void setAlbum(String title) {
    album=title;
  }
  public String getAlbum() {
    return album;
  }
..
}
 

I have created a servlet ShoppingServlet.java in the servlet directory. When i try to compile it, it gives an error


package shopping does not exist

ShoppingServlet.java

import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import shopping.CD;
 
public class ShoppingServlet extends HttpServlet {
  public void init(ServletConfig conf) throws ServletException  {
    super.init(conf);
  }
  public void doPost (HttpServletRequest req, HttpServletResponse res)
      throws ServletException, IOException {
    HttpSession session = req.getSession(false);
    if (session == null) {
      res.sendRedirect("http://localhost:8080/error.html");
    }
    Vector buylist=
      (Vector)session.getValue("shopping.shoppingcart");
    String action = req.getParameter("action");
    if (!action.equals("CHECKOUT")) {
      if (action.equals("DELETE")) {
        String del = req.getParameter("delindex");
        int d = (new Integer(del)).intValue();
        buylist.removeElementAt(d);
      } else if (action.equals("ADD")) {
        //any previous buys of same cd?
        boolean match=false;
        CD aCD = getCD(req);
        if (buylist==null) {
          //add first cd to the cart
          buylist = new Vector(); //first order
          buylist.addElement(aCD);
        } else { // not first buy
          for (int i=0; i< buylist.size(); i++) {
            CD cd = (CD) buylist.elementAt(i);
            if (cd.getAlbum().equals(aCD.getAlbum())) {
              cd.setQuantity(cd.getQuantity()+aCD.getQuantity());
              buylist.setElementAt(cd,i);
              match = true;
            } //end of if name matches
          } // end of for
          if (!match) 
            buylist.addElement(aCD);
        }
      }
      session.putValue("shopping.shoppingcart", buylist);
      String url="/jsp/shopping/EShop.jsp";
      ServletContext sc = getServletContext();
      RequestDispatcher rd = sc.getRequestDispatcher(url);
      rd.forward(req, res);
    } else if (action.equals("CHECKOUT"))  {
      float total =0;
      for (int i=0; i< buylist.size();i++) {
        CD anOrder = (CD) buylist.elementAt(i);
        float price= anOrder.getPrice();
        int qty = anOrder.getQuantity();
        total += (price * qty);
      }
       ..
      RequestDispatcher rd = sc.getRequestDispatcher(url);
      rd.forward(req,res);
    }
  }
  private CD getCD(HttpServletRequest req) {
  ..
  }
}

Please tell me how can i resolve this.

i guess u r compiling from wrong directory...

u need to be at classes folder and compile using the following command at command prompt..

...../classes> javac servlet/ShoppingServlet.java

i guess this should work as if you are trying to compile from inside servlet folder then it will look for a folder named shopping inside servlet as u might have written

import shopping.CD;

inside your ShoppingServlet.java.

hope this helps.. if still in doubt do revert back.

Bye and take Care

[sylvia greene]

thanks a lot. that worrks fine.
I have another problem though

In the webapps directory i have a shopping directory in which i have a jsp file EShop.jsp which has the following action attribute

<form name="shoppingForm" action="../ShoppingServlet" method="POST">  

It is looking for a servlet which is in WEB-INF/classes/servlet folder
ShoppingServlet.java

 package servlet;
 
import java.util.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import shopping.CD;
 
public class ShoppingServlet extends HttpServlet {
  public void init(ServletConfig conf) throws ServletException  {
    .....
 

Following is the web.xml i have created for this

 
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
   PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
   "http://java.sun.com/dtd/web-app_2_3.dtd">
 
<web-app>
   <servlet>
      <servlet-name>ShoppingServlet</servlet-name>
      <servlet-class>servlet.ShoppingServlet</servlet-class>
   </servlet>
 
   <servlet-mapping>
      <servlet-name>ShoppingServlet</servlet-name>
  <url-pattern>/ShoppingServlet</url-pattern>
   </servlet-mapping>
</web-app>
 
 

But when i submit i get REsource not found with the url as
http://localhost:8080/ShoppingServlet

hi,

good that last oje worked fine...

now the prob is that you r putting extra .. in your action

write like this..

<form name="shoppingForm" action="/ShoppingServlet" method="POST">

this will work fine..

if any more doubts .. do revert backk

bye
