HttpServletRequest.getHeaders(aString)

[Nasser Aboobaker]

Hi friends
I am getting compile time error while compiling this following code.
It says
1."No method found matching getHeaders(String)
2."Cannot parse initializer Enumeration values = req.getHeaders(name)
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HeaderSnoop extends HttpServlet{
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException{
res.setContentType("text/plain");
PrintWriter out = res.getWriter();
out.println("Request Headers");
out.println();
Enumeration names = req.getHeaderNames();
while(names.hasMoreElements()){
String name = (String)names.nextElement();
Enumeration values = req.getHeaders(name);
if(values != null){
while (values.hasMoreElements()){
String value = (String)values.nextElement();
out.println(name + ": " + value);
}
}
}
}
}

Can some one enlighten me in this matter!.
Thanks in advance

Maybe you have a v2.1 servlet container? I think this method was only introduced in v2.2 of the API.

You are correct peter, this method was introduced with version 2.2. Version 2.1 has a getHeader method.

Hi Peter, Bosun,
thanks for your reply.
Can you advice me where to get latest servlet container and how to change the current one I am having. I have Tomcat 3.2 installed and working. Is that an old version?.
Thanks for your time and help.
