我对这门课有一个问题：
package it.test;
import java.net.Socket;
import java.net.ServerSocket;
import java.io.*;
import javax.naming.*;
import javax.naming.directory.*;
import java.util.Calendar;
import java.util.Hashtable;
public class ReadTimeoutTest {
public static void main(String[] args) throws Exception {
boolean passed = false;
// Set up the environment for creating the initial context
Hashtable<String, String> env = new Hashtable<String, String>(11);
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put("com.sun.jndi.ldap.read.timeout", "1000");
env.put(Context.PROVIDER_URL, "ldap://localhost:2001");
Server s = new Server();
try {
// start the server
s.start();
// Create initial context
DirContext ctx = new InitialDirContext(env);
System.out.println("LDAP Client: Connected to the Server");
// Close the context when we're done
ctx.close();
} catch (NamingException e) {
e.printStackTrace();
System.out.println("Server: Connection refused"+" "
+Calendar.getInstance().getTime());
}
s.interrupt();
}
static class Server extends Thread {
static int serverPort = 2001;
Server() {
}
public void run() {
try {
ServerSocket serverSock = new ServerSocket(serverPort);
Socket socket = serverSock.accept();
System.out.println("Server: Connection accepted"+" "
+Calendar.getInstance().getTime());
BufferedInputStream bin = new BufferedInputStream(socket.
getInputStream());
while (true) {
bin.read();
}
} catch (IOException e) {
// ignore
}
}
}
}
它应该测试 ldap 调用的超时，在超时后得到一个 naimngException 它在 Windows 中可以正常工作，但在 linux 中却不行，它会继续等待 ldap 连接。我无法在 linux 中正确设置超时，没有得到 NamingException。我应该怎么办？
