import java.util.*;
import java.io.*;
import java.net.*;

public final class mwebserver
{
public static void main(String args[]) throws Exception
{
int port = 6789;
//define the port
ServerSocket listensocket = new ServerSocket(port);
while (true)
{
Socket connectionsocket = listensocket.accept();
}

HttpRequest request = new HttpRequest(connectionsocket);

//creat a new thread to process the request
Thread thread1 = new Thread (request);
thread1.start();
}

static class HttpRequest implements Runnable
{
  final static String CRLF = "\r\n";
  Socket socket1;

  //constructor
  public HttpRequest(Socket socket1) throws Exception
  {
    this.socket1 = socket1;
  }

  //implement the run()method of the runnable interface
  public void run()
  {
    try
    {
      processrequest();
    }
    catch(Exception e)
    {
      System.out.println(e);
    }
private void processrequest() throws Exception
  {
    InputStream is = new InputStream ();
    DataOutputStream os = new DataOutputStream(socket1.getOutputStream());

   //set up input stream filters

   BufferedReader br = new BufferedReader(new InputStreamReader(socket1.getInputStream()));

   //get the request line of the http request message
   String requestline = br.readLine();
   System.out.println();
   System.out.println(requestline);
这是我编的多线程web服务器的一段源程序，每次编译的时候
HttpRequest request = new HttpRequest(connectionsocket);这一句都报错，请大家帮帮看看。

while (true)
{
Socket connectionsocket = listensocket.accept();
}

HttpRequest request = new HttpRequest(connectionsocket);
我想你的错误可能是，connectionsocket这个变量未定义，Socket connectionsocket = listensocket.accept();你在while语句里定义的，所以它的作用范围就在while语句里，可以这样写：

while(true)
{
Socket connectionsocket = listensocket.accept();
HttpRequest request = new HttpRequest(connectionsocket);

//creat a new thread to process the request
Thread thread1 = new Thread (request);
thread1.start();
}
