Question

从Java客户端-Eclipse消耗Windows认证的WebService时，我收到错误

    at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
    at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:876)
    at java.net.InetAddress.getAddressFromNameService(InetAddress.java:1229)
    at java.net.InetAddress.getAllByName0(InetAddress.java:1180)
    at java.net.InetAddress.getAllByName(InetAddress.java:1110)
    at java.net.InetAddress.getAllByName(InetAddress.java:1046)

这是我的代码，虽然形状不是很好。让我知道如何解决此错误。如果还有任何进一步链接到我的位置，请建议。

Answer 1

尝试使用“-Djava.net.preferIPv4Stack = true”运行应用程序，看看它做了什么

Answer 2

这是一个简单的ntlm + httpclient工作代码我相信它会给你一些基本的想法来配置ntlm

        DefaultHttpClient httpclient = new DefaultHttpClient();
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.NTLM);
httpclient.getParams().setParameter(AuthPNames.TARGET_AUTH_PREF, authpref);
NTCredentials creds = new NTCredentials("username", "pwd", "server", "domain");
httpclient.getCredentialsProvider().setCredentials(AuthScope.ANY, creds);

HttpHost target = new HttpHost("localhost", 80, "http");

// Make sure the same context is used to execute logically related requests
HttpContext localContext = new BasicHttpContext();

// Execute a cheap method first. This will trigger NTLM authentication
HttpGet httpget = new HttpGet("/index.html");
HttpResponse response = httpclient.execute(target, httpget, localContext);
HttpEntity entity = response.getEntity();
System.out.println(EntityUtils.toString(entity));

从java客户端使用.net webservice时java.net.UnknownHostException
