javax.security.auth.login.LoginException When consume WCF web service with java client using apache cxf

I have a simple wcf in website hosted on iis and I try to call it from java client web application on
wildfly 10
I used apache cxf to implement web service client as below :
#WebServiceClient
(name="BankService",targetNamespace="http://tempuri.org/",
wsdlLocation="http://khalil/BankService-15-7-2016/Service.svc?wsdl")
public class BankService extends Service
{
private final static URL BANKSERVICE_WSDL_LOCATION;
private final static WebServiceException BANKSERVICE_EXCEPTION;
private final static QName BANKSERVICE_QNAME = new QName("http://tempuri.org/", "BankService");
static {
URL url = null;
WebServiceException e = null;
try {
url = new URL("http://khalil/BankService-15-7-2016/Service.svc?wsdl");
} catch (MalformedURLException ex) {
e = new WebServiceException(ex);
}
BANKSERVICE_WSDL_LOCATION = url;
BANKSERVICE_EXCEPTION = e;
}
public BankService() {
super(__getWsdlLocation(), BANKSERVICE_QNAME);
}
public BankService(WebServiceFeature... features) {
super(__getWsdlLocation(), BANKSERVICE_QNAME, features);
}
public BankService(URL wsdlLocation) {
super(wsdlLocation, BANKSERVICE_QNAME);
}
public BankService(URL wsdlLocation, WebServiceFeature... features) {
super(wsdlLocation, BANKSERVICE_QNAME, features);
}
public BankService(URL wsdlLocation, QName serviceName) {
super(wsdlLocation, serviceName);
}
public BankService(URL wsdlLocation, QName serviceName, WebServiceFeature... features) {
super(wsdlLocation, serviceName, features);
}
#WebEndpoint(name = "WSHttpBinding_IBankService")
public IBankService getWSHttpBindingIBankService() {
return super.getPort(new QNam("http://tempuri.org/","WSHttpBinding_IBankService"),IBankService.class);
}
#WebEndpoint(name = "WSHttpBinding_IBankService")
public IBankService getWSHttpBindingIBankService(WebServiceFeature... features) {
return super.getPort(new QName("http://tempuri.org/", "WSHttpBinding_IBankService"),
IBankService.class, features);
}
private static URL __getWsdlLocation() {
if (BANKSERVICE_EXCEPTION!= null) {
throw BANKSERVICE_EXCEPTION;
}
return BANKSERVICE_WSDL_LOCATION;
}
}
and I call ws operation as below :
BankService bank_service = new BankService();
IBankService bank_port = bank_service.getWSHttpBindingIBankService();
double b = bank_port.getBalance(123456L);
and this exeption is thrown :

In IIS manager I set anonymous authentication to enable but same result
also I try to provide username and passowrd in client application like that
BindingProvider prov = (BindingProvider) port;
prov.getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "ComputerName\\MyUSERNAME");
prov.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "MYPASSWORD");
also not work .
Can anyone help me with it please?

Spring Integration | DSL

I am trying to send a file to Remote SFTP server. I have created a factory and an outboundFlow for the same.
UploaderSftpConnectionFactoryBuilder
#Configuration
public class UploaderSftpConnectionFactoryBuilder {
#Value("${report-uploader.sftp-factory.host}")
private String host = null;
#Value("${report-uploader.sftp-factory.port}")
private Integer port = null;
#Value("classpath:${report-uploader.sftp-factory.privateKey}")
private Resource privateKey = null;
#Value("${report-uploader.sftp-factory.privateKeyPassphrase}")
private String privateKeyPassphrase = null;
#Value("${report-uploader.sftp-factory.maxConnections}")
private String maxConnections = null;
#Value("${report-uploader.sftp-factory.user}")
private String user = null;
#Value("${report-uploader.sftp-factory.poolSize}")
private Integer poolSize = null;
#Value("${report-uploader.sftp-factory.sessionWaitTimeout}")
private Long sessionWaitTimeout = null;
//#Bean(name = "cachedSftpSessionFactory")
public DefaultSftpSessionFactory getSftpSessionFactory() {
DefaultSftpSessionFactory defaultSftpSessionFactory = new DefaultSftpSessionFactory();
Optional.ofNullable(this.getHost()).ifPresent(value -> defaultSftpSessionFactory.setHost(value));
Optional.ofNullable(this.getPort()).ifPresent(value -> defaultSftpSessionFactory.setPort(port));
Optional.ofNullable(this.getPrivateKey()).ifPresent(
value -> defaultSftpSessionFactory.setPrivateKey(privateKey));
Optional.ofNullable(this.getPrivateKeyPassphrase()).ifPresent(
value -> defaultSftpSessionFactory.setPrivateKeyPassphrase(value));
Optional.ofNullable(this.getUser()).ifPresent(value -> defaultSftpSessionFactory.setUser(value));
return defaultSftpSessionFactory;
}
#Bean(name = "cachedSftpSessionFactory")
public CachingSessionFactory<LsEntry> getCachedSftpSessionFactory() {
CachingSessionFactory<LsEntry> cachedFtpSessionFactory = new CachingSessionFactory<LsEntry>(
getSftpSessionFactory());
cachedFtpSessionFactory.setPoolSize(poolSize);
cachedFtpSessionFactory.setSessionWaitTimeout(sessionWaitTimeout);
return cachedFtpSessionFactory;
}
public String getHost() {
return host;
}
public void setHost(String host) {
this.host = host;
}
public Resource getPrivateKey() {
return privateKey;
}
public void setPrivateKey(Resource privateKey) {
this.privateKey = privateKey;
}
public String getPrivateKeyPassphrase() {
return privateKeyPassphrase;
}
public void setPrivateKeyPassphrase(String privateKeyPassphrase) {
this.privateKeyPassphrase = privateKeyPassphrase;
}
public String getMaxConnections() {
return maxConnections;
}
public void setMaxConnections(String maxConnections) {
this.maxConnections = maxConnections;
}
public Integer getPort() {
return port;
}
public void setPort(Integer port) {
this.port = port;
}
public String getUser() {
return user;
}
public void setUser(String user) {
this.user = user;
}
}
Now i want to test the outbound flow using an integration test. For that i have created below testContext:
TestContextConfiguration
#Configuration
public class TestContextConfiguration {
#Configuration
#Import({ FakeSftpServer.class, JmxAutoConfiguration.class, IntegrationAutoConfiguration.class,
UploaderSftpConnectionFactoryBuilder.class })
#IntegrationComponentScan
public static class ContextConfiguration {
#Value("${report-uploader.reportingServer.fileEncoding}")
private String fileEncoding;
#Autowired
private FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("cachedSftpSessionFactory")
//CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
DefaultSftpSessionFactory cachedSftpSessionFactory;
#Bean
public IntegrationFlow sftpOutboundFlow() {
return IntegrationFlows
.from("toSftpChannel")
.handle(Sftp.outboundAdapter(this.cachedSftpSessionFactory, FileExistsMode.REPLACE)
.charset(Charset.forName(fileEncoding)).remoteFileSeparator("\\")
.remoteDirectory(this.fakeSftpServer.getTargetSftpDirectory().getPath())
.fileNameExpression("payload.getName()").autoCreateDirectory(true)
.useTemporaryFileName(true).temporaryFileSuffix(".tranferring")
).get();
}
#Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
}
I have also created a fake sftp server as suggested # https://github.com/spring-projects/spring-integration-java-dsl/blob/master/src/test/java/org/springframework/integration/dsl/test/sftp/TestSftpServer.java
Below is my fake server:
FakeSftpServer
#Configuration("fakeSftpServer")
public class FakeSftpServer implements InitializingBean, DisposableBean {
private final SshServer server = SshServer.setUpDefaultServer();
private final int port = SocketUtils.findAvailableTcpPort();
private final TemporaryFolder sftpFolder;
private final TemporaryFolder localFolder;
private volatile File sftpRootFolder;
private volatile File sourceSftpDirectory;
private volatile File targetSftpDirectory;
private volatile File sourceLocalDirectory;
private volatile File targetLocalDirectory;
public FakeSftpServer() {
this.sftpFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
sftpRootFolder = this.newFolder("sftpTest");
targetSftpDirectory = new File(sftpRootFolder, "sftpTarget");
targetSftpDirectory.mkdir();
}
};
this.localFolder = new TemporaryFolder() {
#Override
public void create() throws IOException {
super.create();
File rootFolder = this.newFolder("sftpTest");
sourceLocalDirectory = new File(rootFolder, "localSource");
sourceLocalDirectory.mkdirs();
File file = new File(sourceLocalDirectory, "localSource1.txt");
file.createNewFile();
file = new File(sourceLocalDirectory, "localSource2.txt");
file.createNewFile();
File subSourceLocalDirectory = new File(sourceLocalDirectory, "subLocalSource");
subSourceLocalDirectory.mkdir();
file = new File(subSourceLocalDirectory, "subLocalSource1.txt");
file.createNewFile();
}
};
}
#Override
public void afterPropertiesSet() throws Exception {
this.sftpFolder.create();
this.localFolder.create();
this.server.setPasswordAuthenticator((username, password, session) -> true);
this.server.setPort(this.port);
this.server.setKeyPairProvider(new SimpleGeneratorHostKeyProvider(new File("src/test/resources/hostkey.ser")));
this.server.setSubsystemFactories(Arrays.<NamedFactory<Command>>asList(new SftpSubsystemFactory()));
this.server.setFileSystemFactory(new VirtualFileSystemFactory(sftpRootFolder.toPath()));
this.server.start();
}
#Override
public void destroy() throws Exception {
this.server.stop();
this.sftpFolder.delete();
this.localFolder.delete();
}
public File getSourceLocalDirectory() {
return this.sourceLocalDirectory;
}
public File getTargetLocalDirectory() {
return this.targetLocalDirectory;
}
public String getTargetLocalDirectoryName() {
return this.targetLocalDirectory.getAbsolutePath() + File.separator;
}
public File getTargetSftpDirectory() {
return this.targetSftpDirectory;
}
public void recursiveDelete(File file) {
File[] files = file.listFiles();
if (files != null) {
for (File each : files) {
recursiveDelete(each);
}
}
if (!(file.equals(this.targetSftpDirectory) || file.equals(this.targetLocalDirectory))) {
file.delete();
}
}
}
Finally below is my test class
TestConnectionFactory
#ContextConfiguration(classes = { TestContextConfiguration.class }, initializers = {ConfigFileApplicationContextInitializer.class})
#RunWith(SpringJUnit4ClassRunner.class)
#DirtiesContext
public class TestConnectionFactory {
#Autowired
#Qualifier("cachedSftpSessionFactory")
CachingSessionFactory<LsEntry> cachedSftpSessionFactory;
//DefaultSftpSessionFactory cachedSftpSessionFactory;
#Autowired
FakeSftpServer fakeSftpServer;
#Autowired
#Qualifier("toSftpChannel")
private MessageChannel toSftpChannel;
#After
public void setupRemoteFileServers() {
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getSourceLocalDirectory());
this.fakeSftpServer.recursiveDelete(this.fakeSftpServer.getTargetSftpDirectory());
}
#Test
public void testSftpOutboundFlow() {
boolean status = this.toSftpChannel.send(MessageBuilder.withPayload(new File(this.fakeSftpServer.getSourceLocalDirectory() + "\\" + "localSource1.txt")).build());
RemoteFileTemplate<ChannelSftp.LsEntry> template = new RemoteFileTemplate<>(this.cachedSftpSessionFactory);
ChannelSftp.LsEntry[] files = template.execute(session ->
session.list(this.fakeSftpServer.getTargetSftpDirectory() + "\\" + "localSource1.txt"));
assertEquals(1, files.length);
//assertEquals(3, files[0].getAttrs().getSize());
}
}
Now when i am running this test, I am getting the below exception:

which i am not able to resolve it and stuck on it for quite a time now. I am a beginner with spring-integration-dsl and any help woul be really appreciated.

Caused by: java.net.ConnectException: Connection refused: connect
You are connecting to the wrong port.
The test connection factory listens on a random port - you need to use the same port.

When you do a JNDI lookup, you lookup the remote Interface.
so changing your cast to
bean = (UserViewBeanRemote) context.lookup(lookupName);
should do the trick.

Jetty Websocket servlet InstantiationException problems

I'm having problems to make the websocket example of jetty work
public class App {
public static void main(String[] args) {
Server server = new Server(8080);
ServletHandler handler = new ServletHandler();
server.setHandler(handler);
handler.addServletWithMapping(MyEchoServlet.class, "/test/*");
try {
server.start();
server.join();
} catch (Exception e) {
e.printStackTrace();
}
}
public class MyEchoServlet extends WebSocketServlet {
#Override
public void configure(WebSocketServletFactory factory) {
//factory.getPolicy().setIdleTimeout(10000);
factory.register(MyEchoSocket.class);
}
}
#WebSocket(maxMessageSize = 64 * 1024)
public class MyEchoSocket {
Session session;
#OnWebSocketConnect
public void onConnect(Session session){
this.session = session;
System.out.println("init "+session.getUpgradeRequest().getRequestURI().getPath() );
}
#OnWebSocketMessage
public void onText(String msg) {
System.out.println("rec "+msg );
try {
session.getRemote().sendString(msg);
} catch (IOException e) {
e.printStackTrace();
}
}
#OnWebSocketClose
public void onClose(int statusCode, String reason) {
System.out.println("MyWebSocket.onClose()");
}
}
}
gives the following error as soon as I try to create a Websocket from javascript:
var ws = new WebSocket("ws://localhost:8080/test/");

Since you have that declared both your servlet and socket as inner classes, change the following 2 lines of your code ...
// From
public class MyEchoServlet extends WebSocketServlet {
// To
public static class MyEchoServlet extends WebSocketServlet {
// From
public class MyEchoSocket {
// To
public static class MyEchoSocket {
This is because Java cannot just instantiate a non-static inner class.
Try this from your main() method and you'll see ...
Servlet test = new MyEchoServlet();

KINDLY PROVIDE ME WITH THE FIX...TY

...And there you have it: Service implementation URL not specified...
You need to somehow tell GWT where on the backend the RPC call should go. You may do that with the annotation #RemoteServiceRelativePath on the service interface or programmatically on the ServiceDefTarget instance (which is effectively your async service instance).
Cheers,
