I want to retrieve the name and quantity and price, these need to be made form fields ,so I want to put 'hidden' types like this in the servlet.

<input type="hidden" name="price" value="4">
<input type="hidden" name="item" value="sock">

How do you code this in my servlet?

servlet part code....

public class MyBasket extends HttpServlet {


private String startWebPage(){
return "<HTML><HEAD><TITLE>My Basket</TITLE></HEAD><BODY>" +
"<HTML><HEAD><TITLE>My Basket</TITLE></HEAD><BODY>" +
"<FORM action='checkout' method='POST'>" +

"<TABLE ALIGN='center' BORDER='1' WIDTH='50%' CELLSPACING='3' CELLPADDING='3'>" +
"<TR><TH ALIGN='center' VALIGN='top'>Item</TH>" +
"<TH ALIGN='center' VALIGN='top'>Unit Price (�)</TH>" +
"<TH ALIGN='center' VALIGN='top'>Quantity</TH></TR>";
}

private String endWebPage(){
return "<TR><TD ALIGN='center' VALIGN='top' COLSPAN=3>" +
"<INPUT TYPE='submit' VALUE='Continue'>" +
"<INPUT TYPE='reset' VALUE='Clear'></TD></TR></TABLE></FORM></BODY></HTML>";
}

protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();

// Get the value of an initialization parameter
// Get the price parameter value

String parm = getServletConfig().getInitParameter("price");
int price = Integer.parseInt(parm);
String parm1 = getServletConfig().getInitParameter("price1");
int price1 = Integer.parseInt(parm1);
String parm2 =getServletConfig() .getInitParameter("price2");
int price2 = Integer.parseInt(parm2);
String parm3 = getServletConfig().getInitParameter("price3");
int price3 = Integer.parseInt(parm3);
String parm4 = getServletConfig().getInitParameter("price4");
int price4 = Integer.parseInt(parm4);

// Get the item parameter value

String item = getServletConfig().getInitParameter("item");
String item1 = getServletConfig().getInitParameter("item1");
String item2 = getServletConfig().getInitParameter("item2");
String item3 = getServletConfig().getInitParameter("item3");
String item4 = getServletConfig().getInitParameter("item4");



// TODO output your page here

out.println( this.startWebPage() );

out.println("<TR><TD>" + item + "</TD><TD>" + price + "</TD>");
out.println("<TD ALIGN='left' VALIGN='top'>" +
"<SELECT NAME='choices'>" +
"<OPTION>0" +
"<OPTION>1" +
"<OPTION>2" +
"<OPTION>3" +
"<OPTION>4" +
"</SELECT></TD></TR>");
out.println("<TR><TD>" + item1 + "</TD><TD>" + price1 + "</TD>");
out.println("<TD ALIGN='left' VALIGN='top'>" +
"<SELECT NAME='choices1'>" +
"<OPTION>0" +
"<OPTION>1" +
"<OPTION>2" +
"<OPTION>0" +
"<OPTION>0" +
"</SELECT></TD></TR>");
out.println("<TR><TD>" + item2 + "</TD><TD>" + price2 + "</TD>");
out.println("<TD ALIGN='left' VALIGN='top'>" +
"<SELECT NAME='choices2'>" +
"<OPTION>0" +
"<OPTION>1" +
"<OPTION>0" +
"<OPTION>0" +
"<OPTION>0" +
"</SELECT></TD></TR>");
out.println("<TR><TD>" + item3 + "</TD><TD>" + price3 + "</TD>");
out.println("<TD ALIGN='left' VALIGN='top'>" +
"<SELECT NAME='choices3'>" +
"<OPTION>0" +
"<OPTION>1" +
"<OPTION>2" +
"<OPTION>0" +
"<OPTION>0" +
"</SELECT></TD></TR>");
out.println("<TR><TD>" + item4 + "</TD><TD>" + price4 + "</TD>");
out.println("<TD ALIGN='left' VALIGN='top'>" +
"<SELECT NAME='choices4'>" +
"<OPTION>0" +
"<OPTION>1" +
"<OPTION>0" +
"<OPTION>0" +
"<OPTION>0" +
"</SELECT></TD></TR>");
out.println(endWebPage());
out.close();
}

Why are you generating all that markup in a servlet rather than employing a JSP? That's insane.

The paramters are coming from web.xml ,and I want to pass the values into my basket servlet.
So I need to know how to code the hidden types into the servlet, like you can do in html?

You can do that in a JSP.

"gpo",

It looks like you've changed your screen name from something valid to something invalid.
Please go back and make sure it conforms to our JavaRanch Naming Policy
You can do this here

Use a JSP and get rid of this clutter ...
 
Don't get me started about those stupid light bulbs.
