Java itself and NetBeans work fine with NTLMv2 Proxies.
And the problem with installing plugins seems strange to me.
Thanks,

Plugin center requires https://, checking http:// is incorrect and throws the
described exception.
The main difference from other Java applications / NetBeans is that they
probably don't use https://. Do you have a public NTLMv2 Proxy available which
we could use to reproduce & fix the problem?
Lowering the priority, using NTLMv2 Proxy is not a typical case - as a
workaround you can download the plugins manually from
https://visualvm.dev.java.net/servlets/ProjectDocumentList?folderID=11783&expandFolder=11783&folderID=0
and install them using Tools | Plugins | Downloaded.

Unfortunately I don't have a public proxy. This is our corporate proxy.
I understand that https:// is required. But my point was that it can connect to
sites via http:// with the same settings (SAXParseException vs IOException:
Authentication failure).
Recently there were same problem with Eclipse.
They have switched from jre based connection to apache http client and http
client does bot support NTLMv2 Proxies at all.
http://wiki.eclipse.org/ECF_Filetransfer_Support_for_NTLMv2_Proxies
I'll try to look into additional details to be able to find out more.
Thanks,

Actually I have not dealt melodramatically with https behind a proxy. But I've
made some short investigation and want to share my results.
When I am running following
-----import java.io.BufferedReader;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLConnection;
public class RunTest {
public static void main(String[] args) {
try {
System.setProperty("http.proxyHost", "proxy_host");
System.setProperty("http.proxyPort", "proxy_port");
System.setProperty("https.proxyHost", "proxy_host");
System.setProperty("https.proxyPort", "proxy_port");
System.setProperty("http.proxyUser", "DOMAIN
userName");
System.setProperty("http.proxyPassword", "myPasswd");
System.setProperty("https.proxyUser", "DOMAIN
userName");
System.setProperty("https.proxyPassword", "myPasswd");
URL url = new URL(
"http://visualvm.dev.java.net/uc/release12/updates.xml.gz");
URLConnection urlConnection = url.openConnection();
DataInputStream dis = new DataInputStream(urlConnection
.getInputStream());
BufferedReader reader = new BufferedReader(new InputStreamReader(
dis));
String inputLine;
while ((inputLine = reader.readLine()) != null)
{ System.out.println(inputLine); }
dis.close();
} catch (MalformedURLException me)
{ System.out.println("MalformedURLException: " + me); }
catch (IOException ioe)
{ System.out.println("IOException: " + ioe); }
}
}
-----it works fine and I see content of the page. But when I am changing
URL url = new URL("http://visualvm.dev.java.net/uc/release12/updates.xml.gz");
to
URL url = new URL("https://visualvm.dev.java.net/uc/release12/updates.xml.gz");
I get
java.io.IOException: Authentication failure
I've tried both plain text and base64 encoded proxy user name and password for
https proxy env. variables but with no luck.
I have visualvm that comes with jdk 1.6.16 (also I've tested this with visualvm
1.2) and when I want to set proxy it suggests to use env. variables http.proxy*.
And it works fine but only for http://. I am not sure about other types of
proxies but with our NTLMv2 Proxy just setting
–
https.proxyPort
https.proxyHost
https.proxyUser
https.proxyPassword
–
does not work for https://.
I hope this will help to resolve this problem.
Thanks,
Serhiy

I assume you're getting this content using http://
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a

</body></html>
This means you don't have access to the plugin center which is only available
using https://.
The "java.io.IOException: Authentication failure" shows that you are unable to
access https:// using the proxy even from a simple Java application. Not sure
what to do, but it looks like a configuration problem of the proxy or your system.
Comment by jsedlacek [ 27/Oct/09 ]
Just a quick idea - the JDK comes with preinstalled certificates for trusted
servers incl. *.dev.java.net. You could probably get the "java.io.IOException:
Authentication failure" if the certificate is missing on your side. Did you
modify the jre/lib/security/cacerts file or are you modifying
javax.net.ssl.trustStore system property?
Comment by thurka [ 27/Oct/09 ]
Can you provide whole stacktrace of "java.io.IOException: Authentication failure"? Thanks.
Comment by jsedlacek [ 27/Oct/09 ]
Not sure if JDK fully supports NTLMv2, see
http://forums.sun.com/thread.jspa?threadID=5362388 mentioning a third-party
library implementing additional security provider for NTLM.
Comment by 4bugzilla [ 27/Oct/09 ]
Actually java supports NTLMv2 at least for http://. This is because I can get
content of any site accessible via http using code sample I've posted. The only
problem is with https://
And as far as I can see that forum is about Apache's HttpClient. But not about
jre support.
Comment by jsedlacek [ 27/Oct/09 ]
Right, I meant it might be not fully supported by the JDK. Anyway, this looks
like a general Java problem unrelated specifically to VisualVM. We likely won't
be able to resolve it on our side.
Please update this issue if you find any way to make the VisualVM working with a
NTLMv2 proxy.
