I'm trying to teach myself JSP and create something for my portfolio.

I decided to set up a prototype for an "Alternative" on-line bookstore.

Here's the code for an "Item Page"

Code:



<%@page contentType="text/html"%>

<html>

<head>

<style> 

<!--Style Sheet--> 

</style> 

<title>Islam A Short History</title>

</head>

<body>

<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>

<%-- <jsp:getProperty name="beanInstanceName"  property="propertyName" /> --%>

<table width='640'>

<tr> 

<td width='640' colspan='2'> 

<h1 align='center'>The People's Bookstore</h1> 

</td> 

</tr> 

<tr> 

<td width='640' colspan='2'> 

<h2 align='center'>Knowledge Is Power</h2>

</td> 

</tr>

<tr> 

<td width='100'> 

<IMG src='./Images/Islam.gif' alt='Islam--A Short History'>

</td> 

<td width='540'>

 

<!--May become a review or suggestion area--> 

</td> 

</tr>

<tr> 

<td width='640' colspan='2'> 

<form action='./processOrder_DEBUG.jsp' method='get'>

<input type='hidden' name='title' value='Islam--A Short History'>

<b>Islam--A Short History<br> 

Karen Armstrong</b> 

<br> 

<b>Price:</b> <input type='text' name='price' maxlength='7' value="$19.95"

readonly>

<!--For the price, may need to do some funny programming here--> 

<input type='hidden' name='cost' value='19.95'>

<br>



<b>Amount:</b> 

<select name='quantity'>

<option value='1'>1</option> 

<option value='2'>2</option> 

<option value='3.'>3</option> 

<option value='4'>4</option> 

<option value='5'>5</option>

</select>

</td> 

</tr> 

<tr> 

<td width='640' colspan='2'> 

<input type='submit' name='purchase' value='Purchase'>

<input type='reset' value='Cancel'> 

</td> 

</tr> 

</form> 

<tr> 

<td width='640' colspan='2'> 

<center>

<a href='Index.Jsp'>[Back To Home]</a> 

</center> 

</td> 

</tr> 

<tr> 

<td width='640' colspan='2'> 

<%@ include file='Copyright.html' %>

</table> 

</body>

</html>

And the code for the order processor

Code:



<%@page contentType="text/html" import="java.lang.Float" %>

<html>

<head><title>JSP Page</title></head>

<body>

<%-- <jsp:useBean id="beanInstanceName" scope="session" class="package.class" /> --%>

<%-- <jsp:getProperty name="beanInstanceName"  property="propertyName" /> --%>

<%-- Get the variables from the referer page --%>

<% 

    //Declare the varaibles to hold the values 

    //String[] title, price, quantity;

    

    String[] title;

    String[] price; 

    String[] quantity; 

    //String total; 



    //For processing the price, quantity and total 

    Float flPrice, flQuantity; 



    //Fill in the variables

    title= request.getParameterValues("title"); 

    price = request.getParameterValues("cost"); 

    quantity = request.getParameterValues("quantity"); 



    //Some code to figure out the bill 

    flPrice = new Float(price[0]); 

    flQuantity = new Float(quantity[0]); 



    float totalCost = (flPrice.floatValue() * flQuantity.floatValue());

   

%>



<h1>THANK YOU</h1> 



Your order is: 

<br> 

<b>Title:</b> <% out.print(title[0]); %><br> 

<b>Quantity:</b> <%out.print(quantity[0]); %><br> 

<b>Total:</b> <% out.print(totalCost); %><br>  

</body>

</html>

I'm running Forte for Java and using the Tomcat server that came with Forte.

I don't have time to pore over code but for the next person who tries to answer this:

What isn't working? What did you expect the code to do that is not happening?

Any error messages?

I knew I forgot something
It doesn't go from the Item Page to the processor page.

I'm not that good with JSP and would have to configure a server (I am not on my PC and I don't have the option to install a server here) to see why that isn't working. So I can't say why the values aren't being passed (is the processing page named correctly? Is the capital letter in the action field correct?).

Another thing is that A2K is admittedly weak in this topic (web development) so this might not get answered till I beef up this category with more developers.
