Fail to run TomCat 3.1 (pls help)

[Arion <ar...@talentinfo.com.hk>]

I have just downloaded TomCat 3.1 and try to run it on Windows NT, it
gives me the following:

E:\tomcat>tomcat run
Using classpath:
.\classes;.\webserver.jar;.\lib\servlet.jar;.\lib\jasper.jar;.\webpages\WEB-INF\classes\jsp\beans;.\lib\xml.jar;e:\jdk1.2.2\lib\tools.jar;.;e:\jdk1.2.2\lib\tools.jar

I am using jdk1.2.2 and have already set the classpath for it:

CLASSPATH=.;e:\jdk1.2.2\lib\tools.jar

I have also tried to create a ServerSocket myself, it success!

//begin code
import java.io.*;
import java.net.*;

public class PortTest {
 public static void main(String[] args) {
  try {
   int port = Integer.parseInt(args[0]);
   System.out.println("Setup Server on " + String.valueOf(port));
   ServerSocket ss = new ServerSocket(port);
   ss.close();
   System.out.println("OK");
  } catch (Exception e) {
   e.printStackTrace();
  }
 }
}
//end code

What's wrong?

Thank you
