Some compiling problem with java files in JSP

Question

I wrote a file "ProductManager.java" to use the class of Product to do certain functions which are executed in a jsp, however, there are some curious errors.
C:\Tomcat\webapps\examples\WEB-INF\classes\com\wrox\begjsp\arrayexample3>javac P
roductManager.java

Here is the source code:
Product.java
package com.wrox.begjsp.arrayexample3;
public class Product {
private int productId;
private String productName;
private double productPrice;
public Product(int prodid, String prodname, double prodprice) {
productId = prodid;
productName = prodname;
productPrice = prodprice;
public int getProductId(){
return productId;
public void setProductId(int ProductId){
this.productId = ProductId;
public String getProductName(){
return productName;
public void setProductName(String ProductName){
this.productName = ProductName;
public double getProductPrice(){ return productPrice; }
public void setProductPrice(double productPrice){
this.productPrice = productPrice;
ProductManager.java
package com.wrox.begjsp.arrayexample3;
public class ProductManager{
private Product[] productList = new Product[3];
private int productCount;
public ProductManager() {
initializeProductList();
private void initializeProductList() {
productList[0] = new Product(1,"Wrox Press Beginning JSP",49.99);
productList[1] = new Product(2,"Wrox Press Professional JSP",59.99);
productList[2] = new Product(3,"Wrox Press Beginning Java",39.99);
public Product[] getProductList(){
return productList;
public int getProductCount(){
return productList.length;
public Product getProductDetails(int prodid) {
int ProductIndex = -1;
for(int i=0;i<this.getProductCount();i++) {
if (prodid == productList.getProductId()) {
ProductIndex = i;
break;
if (ProductIndex != -1) {
return productList[ProductIndex];
} else {
return null;
Please tell me how to debug it to make it works, thx

Answer 1

add C:\Tomcat\webapps\examples\WEB-INF\classes to your classpath.
You can do this through the control panel or by:
set CLASSPATH=%CLASSPATH%;C:\Tomcat\webapps\examples\WEB-INF\classes
