10 errors

编译我用过

javac -cp ;./httpclient-4.2.jar;jsoup-1.6.3.jar test.java

这是代码

import org.jsoup.Jsoup;

import org.jsoup.nodes.Document;

import org.jsoup.nodes.Element;

import org.jsoup.select.Elements;

import org.apache.commons.httpclient.Cookie;

import org.apache.commons.httpclient.HttpState;

import org.apache.commons.httpclient.HttpClient;

import org.apache.commons.httpclient.methods.GetMethod;

public class test{

public static void main (String []args)throws IOException{

HttpClient client = new HttpClient();

client.getParams().setParameter("username", "SomeUSER");

client.getParams().setParameter("password", "GF@QT#$WE");

GetMethod method = new GetMethod("https://online.investools.com/authentication/auth.iedu");

try{

client.executeMethod(method);

Cookie[] cookies = client.getState().getCookies();

for (int i = 0; i < cookies.length; i++) {

Cookie cookie = cookies[i];

System.err.println(

"Cookie: " + cookie.getName() +

", Value: " + cookie.getValue() +

", IsPersistent?: " + cookie.isPersistent() +

", Expiry Date: " + cookie.getExpiryDate() +

", Comment: " + cookie.getComment());

}

client.executeMethod(method);

}

catch(Exception e) {

System.err.println(e);

}

finally {

method.releaseConnection();

}

我很困惑,不知道我做错了什么.我认为它很简单,但我已经检查过几次并且它存在并且jsoup编译得很好.

谢谢
