JAX WS com.sun.xml.internal.ws.client.ClientTransportException：HTTP 传输错误：java.net.ConnectException：连接被拒绝

Question

I am new to JAX-WS. I am trying to access a web service on a remote machine within the company.

I used wsimport tool to generate JAVA classes from the WSDL resource which is present on our intranet. Java files have been successfully created.

I tried sending a request through SOAPUI, I get a valid response. But when I try to run my code it throws Connection refused.

Here is my code.

URL url = new URL("https://xmattersqa.com/api/services/xmatters-4.1.7?wsdl");

QName qname = new QName("http://www.xmatters.com/webservices/schema#4.1.7", "xmatters-   4.1.7");

FindWhoIsOnDuty f = new FindWhoIsOnDuty();  
Xmatters417 cdoubleprime = new Xmatters417(url,qname);

Xmatters417PortType port = cdoubleprime.getXmatters417SOAP11PortHttp();

FindWhoIsOnDutyReturn fresponse = port.findWhoIsOnDuty("fmsopsqa","fmsopsqa", "", "", "",   "Default Company", "Test Grp 1","23/02/2013 0:00:00 AM", "24/02/2013 0:00:00 AM", false);

Later I tried adding this piece of code , and it still doesnt work.

Authenticator.setDefault(new ProxyAuthenticator("fmsopsqa","fmsopsqa"));
System.setProperty("http.proxHost","sprdxmaws401.corp.net");
System.setProperty("http.proxyPort", "8081");

This is what I get

Service Endpoint links seem to be set correctly.

@WebServiceClient(name = "xmatters-4.1.7", targetNamespace = "http://www.xmatters.com/webservices/schema#4.1.7", wsdlLocation = "https://xmattersqa.com/api/services/xmatters-4.1.7?wsdl")

Answer 1

I guess this is way too late but maybe this solution will help others facing the same issue. I just ran into the same problem and found that my proxy-stub-object was calling another URL than I had given to the service object.

java.net.URL wsdlURL = new URL("http://myServiceHost.com/online/myService?wsdl");
Service serviceWebClient = new ServiceWebClient(wsdlURL, new QName("my/namespace", "MyServiceName"));

My debugger showed me then that my service did not try to access the given URL but an internal IP-Address that was inside the projected wsdl on this URL under the service tag.

<service name="MyServiceName">
  <port name="MyServicePort" binding="tns:MyServiceBindingBinding">
    <soap:address location="http://192.168.3.20:9443/online/myService/"/>
  </port>
</service>

so the stub pointed to the endpoint at 192.168.3.20 but my service was not on the same machine and therefore it could obiously not be reached. In order to fix that you have to correct the URL on the stub like this

MyService myService = serviceWebClient.getPort(MyService.class);
BindingProvider bindingProvider = (BindingProvider) myService;
bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL.toString());

this fixed the issue for me

Answer 2

除了防火墙白名单作为可能的原因之外，如果您收到“HTTP 状态代码 404：已处理”，它甚至可能没有该服务方法可用。

Answer 3

This might be dumb, I have a situation where I defined two port biding on get and update operation, acutally they meant the same thing. After removing duplicate, issue fixed. Just in case it may help any one.

Answer 4

As this is the top search result, when searching for this error message. You'll also get the "connection refused" error message, if you're specifying a wrong port number. For me, it was as simple as that. Double check to make sure.
