I am getting the subject mentioned error code in one of my programs. I looked around for solutions on Stackoverflow and tried to follow the suggestions on issues reported by Ilana Platonov and PPr. Unfortunately, these didn't resolve the errors.
As a next step, I simply tried to run the code presented in Ilana Platonov along with the resolutions (accepted there). My code: package examples;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.Authenticator;
import java.net.HttpURLConnection;
import java.net.InetSocketAddress;
import java.net.PasswordAuthentication;
import java.net.Proxy;
import java.net.URL;
public class MyProxyPass {
public MyProxyPass( String proxyHost, int proxyPort, final String userid, final String password, String url ) {
try {
/* Create a HttpURLConnection Object and set the properties */
URL u = new URL( url );
Proxy proxy = new Proxy( Proxy.Type.HTTP, new InetSocketAddress( proxyHost, proxyPort ) );
HttpURLConnection uc = (HttpURLConnection) u.openConnection( proxy );
Authenticator.setDefault( new Authenticator() {
@Override
protected PasswordAuthentication getPasswordAuthentication() {
if (getRequestorType().equals( RequestorType.PROXY )) {
return new PasswordAuthentication( userid, password.toCharArray() );
}
return super.getPasswordAuthentication();
}
} );
uc.connect();
/* Print the content of the url to the console. */
showContent( uc );
}
catch (IOException e) {
e.printStackTrace();
}
}
private void showContent( HttpURLConnection uc ) throws IOException {
InputStream i = uc.getInputStream();
char c;
InputStreamReader isr = new InputStreamReader( i );
BufferedReader br = new BufferedReader( isr );
String line;
while ((line = br.readLine()) != null) {
System.out.println( line );
}
}
public static void main( String[] args ) {
String proxyhost = "xxx.xxx.xx.xx";
int proxyport = xxxx;
final String proxylogin = "JOKER";
final String proxypass = "passxxx";
String url = "http://www.google.de";
String surl = "https://www.google.de";
System.setProperty("javax.net.ssl.trustStore", "C:\\Users\\JOKER\\Documents\\eclipse-jee-photon-R-win32\\eclipse");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
//new MyProxyPass( proxyhost, proxyport, proxylogin, proxypass, url ); // uncomment this line to see that the https request works!
//System.out.println( url + " ...ok" ); // uncomment this line to see that the https request works!
new MyProxyPass( proxyhost, proxyport, proxylogin, proxypass, surl );
System.out.println( surl + " ...ok" );
}
}
However, I still get the same errors that were reported by others:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
https://www.google.de ...ok

at examples.MyProxyPass.main(MyProxyPass.java:63)
What worked for others and not for me:
The often given suggestion about setting the variables jdk.http.auth.tunneling.disabledSchemes and jdk.http.auth.proxying.disabledSchemes to blank did not work. I set these to blank in ..\Java\jdk1.8.0_112\jre\lib\net.properties file.
Tying out with various JVM Args proposed by Andreas Panagiotidis didn't help either.
- From https://bugs.eclipse.org/bugs/show_bug.cgi?id=422665 I also tried to exclude HTTP libraries that might be conflicting. -Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient4
I am using:
- Eclipse IDE Photon Release (4.8.0),
- java version "1.8.0_112" (build 1.8.0_112-b15)
- Windows 10
- I am behind a corporate proxy and have spent two full days on it without success. :(
Let me know if I should attach any other logs.
