http proxy + authentication的使用

teiayu

对于java.lang.reflect.Proxy谈谈大家如何使用的
可能是由于有代理的原因，我编写的程序中的超链接，不能连上外部的网站，所以想用这个解决，但是没有思路，谢谢大家的支持，也是一起学习的过程

此代理非彼代理也～～

sakulagi

这个Proxy是动态代理模式，是一个Design Pattern，不是internet proxy

perryhg

程序启动的时候用 java -Dhttp.proxyHost=192.168.0.1 -Dhttp.proxyPort=3128 myapp

谢谢大家，能告诉我，应该用哪个代理类作呀，谢谢了，是不是这个java.net.Authenticator，找了很久，都没有思路

yovn

1.5中有java.net.Proxy类

sakulagi

楼主用IE或者Firefox直接访问那个网页的话，需要代理么？如果不需要，JEditorPane也应该不需要；

如果需要的话，请用perryhg斑竹的方法

Hello to all Ranchers
this is my first post..

now coming to my problem--

I'm trying to make a simple browser for my application and of many options i choose JEditorPane to implement the browser.

When i try to execute the program i get the following error:

java.io.IOException: Authentication failure
at sun.net.www.protocol.http.HttpURLConnect ... onnection.java:649)
at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:272)
at javax.swing.JEditorPane.getStream(JEditorPane.java:674)
at javax.swing.JEditorPane.setPage(JEditorPane.java:392)
at javax.swing.JEditorPane.setPage(JEditorPane.java:775)
at SwingExamples.EditorPaneFrame.jbInit(EditorPaneFrame.java:41)
at SwingExamples.EditorPaneFrame.<init>(EditorPaneFrame.java:17)
at SwingExamples.EditorPaneFrame.main(EditorPaneFrame.java:50)

I connect to internet through a Web Proxy which needs authentication.
After searching the net and through this forum i found that java.net.Authenticator can be used to provide authentication details.

This is the code i have written:


code:
--------------------------------------------------------------------------------

..............    System.setProperty( "proxySet", "true" );    System.setProperty( "http.proxyHost", "proxyhost" );    System.setProperty( "http.proxyPort", "proxyport" );    Authenticator.setDefault(new SampleAuthenticator());        jEditorPane1.setPage("http://www.google.com");................ class SampleAuthenticator extends Authenticator  {    public PasswordAuthentication getPasswordAuthentication()    {      return new PasswordAuthentication("myUserName", "myPass".toCharArray() );    }  }................

--------------------------------------------------------------------------------



I get the same error even after i use the Authenticator. The JEditorPane establishes a HttpURLConnection by itself, so will it know about the proxy setting and also the authentication detials that i have set?

Any suggestions!!!
