Can you help me translate a Servlet to JSP

here’s the code:

package Inventory;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class DisplayData extends HttpServlet {

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

    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    Item item = (Item) request.getAttribute("invenItem");

    if (item != null) {
        out.println("<html><title>Inventory Item</title>");
        out.println("<body><h1>Inventory Item Details:</h1>");
        out.println("Stock ID  : " + item.getStockID() + "<br/>");
        out.println("Name      : " + item.getItemName() + "<br/>");
        out.println("Unit Price: " + item.getUnitPrice() + "<br/>");
        out.println("On Stock  : " + item.getOnStock() + "<br/>");
        out.println("</body>");
        out.println("</html>");
    } else {
        RequestDispatcher rd =
           request.getRequestDispatcher("/SearchPage.html");
        rd.include(request, response);
        rd = request.getRequestDispatcher("/AddData.html");
        rd.include(request, response);
    }

}

}

I am trying to use the scriplets, but still want to know how to convert:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

to JSP. I try to do this:

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Display Data</title>
</head>
<jsp:useBean id="inventory" class="Inventory.AddData" />
<jsp:directive.page import="java.io.*" />
<jsp:directive.page import="javax.servlet.*" />
<jsp:directive.page import="javax.servlet.http.*" />
<body>

    <%-- But I don't know how to convert this:
         public class DisplayData extends HttpServlet
         in JSP
    --%>

</body>

please Help… thanks in advance

    The cleanest way would be to use JSTL instead of scriptlets (check out a good primer here). In a nutshell, you need to have JSTL JARs installed (either in your app server or in your specific webapp). Then, you can do the following:

    <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
...
<c:out value="${invenItem.stockID}"/>

    The first line imports the JSTL “core” tag library, which gives you access to the basic tags. Then, the tag is used to output data – it will escape special characters for you (for example, suppose stockID has the character “<“). Finally, the ${} is an EL expression, which in this case simply accesses the invenItem request attribute and extracts the stockID value (by calling getStockID()).

    Clean, simple, no ugly Java scriptlets in your JSP view.
