~
I am using TC 4.1.36 and I have a simple Data Transfer Object that I
create in a front controller servlet and use to build a JSP view
~
This is where I have both the servlet and the DTO
~
. . .\webapps08\serv2jspTest\WEB-INF\classes>dir *.* /B
~
UpFlInfoK.class
UpFlInfoK.java
UploadServlet10.class
UploadServlet10.java
~
and this is where I have the jsp pages
~
. . .\webapps08\serv2jspTest>dir *.* /B
serv2jspTest.jsp
~
and this is my jsp page
~
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd";>
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
<jsp:useBean id="UpFlInf" class="UpFlInfoK" />
// __ global data set in jspInit() which runs once
<%!
private final String aDtFrmt = "yyyy-MM-dd_HHmmss"; // @! it should
be read in as input parameter
private SimpleDateFormat SDtF = null;
public void jspInit(){ SDtF = new SimpleDateFormat(aDtFrmt); }
%>
// __ request scoped data runs every time jsp is accessed
<%
UpFlInfoK UpFlInf = request.getAttribute("UpFlInf");
String aLModDt = SDtF.format(new Date(UpFlInf.lL2LModDt));
// __
String aPg = "<p>There already exist a file on the server, uploaded ";
aPg += aLModDt;
aPg += "by user id: ";
aPg += UpFlInf.aUsrID;
aPg += " that is exactly the same as the one you tried to
upload.</p><p>Information about current file on server:<u><li> File
Length: ";
aPg += UpFlInf.lFlL2;
aPg += " (bytes)</li><li> MD5Sum: ";
aPg += UpFlInf.aFlMD5Sum;
aPg += "</li></u></p><p>Do you want to <a
href=javascript.back(-1)>try again</a>?</p>";
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Same File</title>
</head>
<body>
<%=aPg%>
</body>
</html>
~
then I am going:
~
request.setAttribute("UpFlInf", UpFlInf);
request.getRequestDispatcher(aDispatchPg).forward(request, response);
~
but I can't make the jsp page import the class, even though I thought
you should keep all classes in /WEB-INF/classes
~
Where do you put classes so that servlets and JSPs can import and use them?
~
This is the error I am getting:
~
HTTP Status 500 -
