服务器响应405,java.io.IOException：服务器返回HTTP响应代码：405表示URL

我有一个在线servlet，我正在尝试联系以进行一些基本测试。这是servlet代码：

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class index extends HttpServlet {

private static final long serialVersionUID = 1L;

public index() {

super();

}

protected void doGet(HttpServletRequest request,

HttpServletResponse response) throws ServletException, IOException {

PrintWriter out = response.getWriter();

long time1 = System.currentTimeMillis();

long time2 = time1 + 10000;

out.println(time1);

long i = 400000000l;

while (System.currentTimeMillis() < time2) {

i++;

}

out.print(time2);

}

}

现在，我正在尝试使用以下代码从服务器获取信息：

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.net.HttpURLConnection;

import java.net.URL;

public class HttpRequest {

public static void main(String args[]) {

BufferedReader rd;

OutputStreamWriter wr;

try {

URL url = new URL("http://blahblahblah/index");

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setDoOutput(true);

wr = new OutputStreamWriter(conn.getOutputStream());

wr.flush();

conn.setConnectTimeout(50000);

rd = new BufferedReader(

new InputStreamReader(conn.getInputStream()));

String line;

while ((line = rd.readLine()) != null) {

System.out.println(line);

}

} catch (Exception e) {

System.out.println(e.toString());

}

}

}

但是我一直得到同样的405错误。我做错了什么？
