What's wrong with this code?? please help

[Anil Jain]

Hello friends!!
I am trying to compile these codes which belong to same package. The first code compiles allright but the second one gives me errors. Both of them belong to same package.
**********Item.java file****************

package jspin24hrs.hour16;
public class Item {
  String SKU, name, description;
  double price;
  public Item(){}
  public Item(String s, String n, String d, double p){
    SKU= s;
    name = n;
    description = d;
    price = p;
  }
  public String getName(){return name;}
  public String getSku(){return SKU;}
  public String getDescription(){return description;}
  public double getPrice(){return price;}
}

***********ShoppingCart.java file***********
package jspin24hrs.hour16;
import java.util.*;
public class ShoppingCart {
  Vector items = new Vector(10);
  public void addItem(Item i){items.addElement(i);}
  public void deleteItem(String sku){
    Enumeration itemEnum = getItems();
    while(itemEnum.hasMoreElements()){
      Item item = (Item)itemEnum.nextElement();
      if(item.getSku().equals(sku)){
        items.removeElement(item);
        break;
        }
    }
  }
  public void emptyCart(){ items = new Vector(10); }
  public Enumeration getItems(){ return items.elements(); }
  public double computeTotal(){
    Enumeration itemEnum = getItems();
    double total = 0;
    while(itemEnum.hasMoreElements()){
      Item item = (Item)itemEnum.nextElement();
      total = total + item.getPrice();
    }
    return total;
  }
}

I get the folloing errors when i compile the ShoppingCart.java
C:\Tomcat\jakarta\webapps\myJSPApp\WEB-INF\classes\ShoppingCart.java:5: cannot resolve symbol

PLEASE LET ME KNOW WHERE I AM MAKING THE MISTAKE

Look in directory /jspin24hrs/hour16 and see if the Item.class file really IS THERE.

You could try again as followed:
1.set classpath=.;%classpath%
2.come in directory "C:\Tomcat\jakarta\webapps\myJSPApp\WEB-INF\classes\"
3.execute compile command,
java -d . *.java

My guess is it's the class path. Notice a few things. One is both classes are in a package, but from your error code, it looks as though you did NOT putthem in that package folder structure. So you need to do this:
1. put the files in:
${curr_folder}/jspin24hrs/hour16/Item.java
${curr_folder}/jspin24hrs/hour16/ShoppingCart.java
2. Stay in the current Folder and do:
javac -classpath . jspin24hrs/hour16/ShoppingCart.java
Since it uses Item.java, that will compile both files (do not copy the recently compiled Item.class file into the folder).

As another suggestion (though it does not directly relate to your issue), try using the Jikes compiler. The error messages are a bit more clear.
