I am trying to create an HTML form which displays text from a text file, using a Java Servlet. I keep getting the following error: Error instantiating servlet class servlets.ReportServlet.
Here is the HTML page:
<html>
<head>
<title>TODO supply a title</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<form name = "managementReports" method = "get" action =
"ReportServlet">
<input type="submit">
</form>
</body>
</html>And here is my servlet:
package servlets;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import javax.servlet.annotation.WebServlet;
@WebServlet(urlPatterns = { "/ReportServlet" })
public class ReportServlet extends HttpServlet
{
public void service(HttpServletRequest req, HttpServletResponse res) throws
ServletException, IOException
{
res.setContentType("text/html");
PrintWriter pw = res.getWriter();
String name = req.getParameter("filename");
BufferedReader br = new BufferedReader(new
FileReader("c:/Consignment.txt"));
String str;
while( (str = br.readLine()) != null )
{
pw.println(str + "<BR>");
}
br.close();
pw.close();
}
}Here is my web.xml:
