When i run my servlet, it gives me error message saying
10.5.1 500 Internal Server Error
The following is the code which compiles fine
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class TestForm extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException, IOException
{
try{
res.setContentType("text/html");
PrintWriter out = res.getWriter();

String name = req.getParameter("name");
String password = req.getParameter("email");

out.println("<HTML>");
out.println("<HEAD> <TITLE>Testing Form " + "</TITLE></HEAD>");
out.println("<BODY>");
out.println(" Name:");
out.println("<INPUT TYPE = TEXT NAME = name VALUE ="" SIZE=15>");
out.println("Email:");
out.println("<INPUT TYPE = TEXT Email = email VALUE = "" SIZE=15>");
out.println("<INPUT TYPE=SUBMIT value = Ok >");
out.println("</BODY></HTML>");
}catch(IOException e){}
}
}

I am using web logic server and can't figure out why it is giving me this error but simple helloworld works.
Could anyone please help me out.
Thanks,

This servelet is expecting two input parameters. Are you sending these parameters from some HTML form? Could you paste the code for that form too.

Hi
I looked over your code and found the following:
It seems to be working properly now. Alot of your errors were mistakes in the way you presented the HTML code so when you clicked on OK it couldn't process your request properly.
In the future if you could also 'wrap' your code in 'code tags' and indent properly it would be easier to read.
Thanks.

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class TestForm extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
try {
PrintWriter out = res.getWriter();
res.setContentType("text/html");
String name = req.getParameter("name");
String password = req.getParameter("email");

if (name.equals("")) {
// Nothing
} else {
out.println("Name: " + name + " is your 'name'.<BR>");
}

if (password.equals("")) {
// Nothing
} else {
out.println("Password: " + password + " as your 'email'.<BR>");
}
out.println("<HTML>");
//I took out the '+' here as I didn't see the point of it. Ther was no 'variable' to contcatenate.
out.println("<HEAD><TITLE>Testing Form</TITLE></HEAD>");
out.println("<BODY>");

// There was a missing "FORM" tag here
out.println("<FORM METHOD='GET' ACTION='/servlet/TestForm'>");
out.println(" Name:");
// I had to change your VALUE="" to VALUE='' as the double quotes 'end' the println statement.
out.println("<INPUT TYPE=TEXT NAME=name SIZE=15>");
out.println("Email:");
// I had to change your VALUE="" to VALUE='' as the double quotes 'end' the println statement.
// Also there was an Email = email, you should use NAME = email, the NAME is a parameter of the 
// input tag.
// All form elements are NAME = VALUE pairs.
out.println("<INPUT TYPE=TEXT NAME=email SIZE=15>");
// Submit button must be named.
out.println("<INPUT TYPE=SUBMIT name=SUBMIT value=Ok >");
// And a missing </FORM> tag here.
out.println("</FORM>");
out.println("</BODY></HTML>");
} catch(IOException e) {
// Nothing, we ignore it for now.
}
// There was a closing bracket missing.
}
}

SOURCE CODE should be SURROUNDED by "code" tags.

I'm sorry. I don't know what I was thinking when I posted my earlier reply to this message, and asked for the HTML form. May be I was in a hurry and didn't read the message properly. So please ignore my earlier reply to this message.
Thanks John for resolving the problem.
