Cannot Resolve Symbol error in Servlet

Posted: Jan 13, 2003 4:02 PM

I'm having difficulty getting my servlet to compile. I get 2 errors - both "cannot resolve symbol" errors, both are for "variable response" which is not a variable. Can anyone help?
Here's the code:

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class Survey extends HttpServlet {

public void doPost(HttpServletRequest request,
HttpServletResponse respone)
throws ServletException, IOException {
int votes[] = null;
int index;
int vote;
File survdat = new File("survdat.dat");
String gender;
String products[] = {"Conventional TX", "HDTV", "VCR",
"CD Player/recorder", "DIVD player", "Other"};

// Set the content type for the response output and get a writer

response.setContentType( "text/html" );
PrintWriter servletOut = response.setWriter();

// Produce the head of the output document

servletOut.print("<html><head>");
servletOut.println(
"<title> Return message </title></head><body>");

// If the file already exists, read in its data

if (survdat.exists()) {
ObjectInputStream indat = new ObjectInputStream(
new FileInputStream(survdat));
votes = (int []) indat.readObject();
indat.close();
}

// If file does not exist (this is the first vote), create votes array

else
votes = new int[14];

// Get the gender of the survey respondee

gender = request.getParameter("gender");

// Add the consume electronics vote of the response to the votes array

vote = Integer.parseInt(request.getParameter("vote"));
if (gender.equals("male")) vote += 7;
votes[vote]++;

// Write updates votes array to disk

ObjectOutputStream outdat = new ObjectOutputStream(
new FileOutputStream(survdat));
outdat.writeObject(votes);
outdat.flush();
outdat.close();

// Create the initial response information

servletOut.println("<h3>Thank You...</h3>");
servletOut.println("<h4>Current Survey Results:</h4>");

// Create the ttal votes return information for female respondents

servletOut.println("<h5>For Female Respondents </h5>");
for (index = 0; index < 7; index++) {
servletOut.print(products[index]);
servletOut.print(": ");
servletOut.println(votes[index]);
servletOut.println("<br />");
}

// Create the total votes return information for male respondents

servletOut.println("<h5>For Male Respondents </h5>");
for (index = 0; index < 7; index++) {
servletOut.print(products[index - 7]);
servletOut.print(": ");
servletOut.println(votes[index]);
servletOut.println("<br />");
}
servletOut.close();
}
}
