i need to capture some packet data that are being sent to a particular IP of web-server by a GPRS module. i am using rest web service for the capture of packet data. i'm new to this so pardon the stupidities; my doubt was that can we directly access the packet data to a string using #GET annotation to that particular url or should I define a server socket function inside #GET annotation and then listen to it?
i think we should provide server socket function inside #GET annotation.
Like;
#GET
#Path("/hello/path")
public String hello(#PathParam("path") String val) {
ServerSocket server = new ServerSocket(6608);
Socket socket = null;
socket = phone.accept();
InputStream in = socket.getInputStream();
din = new DataInputStream(in);
}

I want to add Authorization header for basic Authorization to my jetty-client request.
I am running two instances on same browser one is server one is client ,Java-8 is being used as a technology, No DB No Spring etc. using org.eclipse.jetty,jetty-websocket,version-8.1.15.v20140411.
I had a websocketEndPointManager class which contains the initialization method for both Server(dedicated class is CSWebsocket) and client(Cpwebsocket).
How can I achieve basic auth in my scenario where server maintains username and password is to matched in current session after its instance is ready, currently my setup able to perform upgrade to websocket but not basic
Snippet of client websocket start method where handshake occur :
private void startCPWebSocket() throws Exception{
String uri ="";
try {
HandlerRegistry.register(this);
WebSocketClientFactory factory = new WebSocketClientFactory();
Configuration configuration = TestSession.getConfiguration();
uri = configuration.getSystemUnderTestEndpoint();
TestSession.getConfiguration().setToolURL("NA");
TestSession.getConfiguration().setSystemUnderTestEndpoint(uri);
factory.start();
WebSocketClient client = factory.newWebSocketClient();
client.setMaxIdleTime(24*60*60*1000);
client.open(new URI(uri.trim()),new CPWebSocket()).get(24*60*60,
TimeUnit.SECONDS);
LogUtils.logInfo("WebSocket URL : "+uri,true);
}
catch (ExecutionException e) {
LogUtils.logError(e.getMessage(), e,false);
LogUtils.logWarn("Could not establish websocket connection.",true);
//System.exit(0);
TestSession.setTerminated(true);
throw e;
Currently I am fighting with the following problem:
I need to forward SOAP requests to an external service in special cases (decision based on tenantId provided in the SOAP message). I created an interceptor for this task to extract tenantId from the message request, get assignment (each tenantId is assigned to its own service instance running on a different server) and if no assignment is made, I need to process the request just as normal.
Currently I implemented on this way: I create HttpUrlConnection in the interceptor and forward the request to an external endpoint (in case there is an assignment) and take the outputStream of the response and send the response over HttpServletResponse.getOutputStream etc...
I also need to consider that the interceptor be used with various service (tenantId must be provided in the SOAP request).
I also read about Provider and Dispatch objects not sure how this should work.
Is there any way to get target service and port (QNames) from the incoming message?
I cannot use Camel at the moment (only CXF is allowed).
Maybe you can try something like this :
/** Your interceptor */
public void handleMessage(SoapMessage msg) throws Fault {
Exchange exchange = msg.getExchange();
Endpoint ep = exchange.get(Endpoint.class);
// Get the service name
ServiceInfo si = ep.getEndpointInfo().getService();
String serviceName = si.getName().getLocalPart();
XMLStreamReader xr = msg.getContent(XMLStreamReader.class);
if (xr != null) { // If we are not even able to parse the message in the SAAJInInterceptor (CXF internal interceptor) this can be null
// You have the QName
QName name = xr.getName();
SOAPMessage msgSOAP = msg.getContent(SOAPMessage.class);
// Read soap msg
if (msgSOAP != null) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
msgSOAP.writeTo(byteArrayOutputStream);
String encoding = (String) msg.get(Message.ENCODING);
String xmlRequest = new String(byteArrayOutputStream.toByteArray(), encoding);
}
// Forward to external service with JAX-RS implementation
Client client = ClientBuilder.newClient()
.target("http://your-target")
.path("/custom-path")
.request()
.post(Entity.entity(xmlRequest, MediaType.APPLICATION_XML));
}
}
Hope this help.
How can I make GET and POST HTTP requests? I found Socket solution, but is it all?
string host = "google.com";
ushort port = 80;
Socket listener = new TcpSocket;
assert(listener.isAlive);
listener.blocking = false;
listener.connect(new InternetAddress(host, port));
char[] msg;
char[] req = cast(char[]) "GET /search.php HTTP/1.1\r\nHost: google.com\r\n\r\n";
listener.send(req);
Take a look at std.net.curl. It has get and post methods:
import std.net.curl;
auto content = get("d-lang.appspot.com/testUrl2");
// --
auto content = post("d-lang.appspot.com/testUrl2", [1,2,3,4]);
curl is undeniably good solution. However, that would add a new dependency to your project, right? Depending on the kind of project you work on, I advise you to use Adam Ruppe's arsd modules, in particular the http module (he is also working on http2 one as well) - https://github.com/adamdruppe/arsd/blob/master/http.d . Or, perhaps if you want a framework, then vibe.d is your best option (http://vibed.org) as it has a HTTP client too. There are two vibe.d related, web development oriented, books that I recommend, and they are listed on the following page: http://vibed.org/tutorials.
UPDATE: There is a fantastic port of Python's requests package you should give a try: https://github.com/ikod/dlang-requests .
You can using hunt-http library to request every website ::
example for get:
import hunt.http;
import std.stdio;
void main()
{
auto client = new HttpClient();
auto request = new RequestBuilder().url("https://www.google.com").build();
auto response = client.newCall(request).execute();
if (response !is null)
{
writeln(response.getBody().asString());
}
}
I am trying to implement a rest web service using Apache CXF and I want to return list of object as a response from server. So i have used generic entity to wrap my list on a server and everything is fine when I enter path from browser. It prints XML representation of object because I have used Jackson JAX-B but when i try to use JAX-RS client. I am getting an exception.

I have written a following client code to get data from server
final Client client = ClientBuilder.newClient();
WebTarget webTarget = client.target(URI.create(PATH));
Response response = webTarget.request(MediaType.APPLICATION_XML).get();
List<ABC> obj = response.readEntity(new GenericType<List<ABC>> (ABC.class){});
But Apart from it I have tried many code to implement CXF client and get data from server but I am getting a same exception almost all the time. I have tried JAXRSCLIENTFactory also to implement client but the same exception.
I ran into the same problem in unmarshalling using the CXF client. Here is how I did it:
Read the response into a String.
Used Gson to convert from string to list of objects.
Note: You will need a wrapper class for your list of objects.
Example:
If the server returns a list of products, Here is how to unmarshall the list:
Create a wrapper class
public class ProductList {
private List<Product> products;
public List<Product> getProducts() {
return products;
}
public void setProducts(List<Product> products) {
this.products = products;
}
}
Code to unmarshall
String responseBody = response.readEntity(String.class);
ProductList productList = new Gson().fromJson(responseBody, ProductList.class);
if(productList.getProducts() != null)
return productList.getProducts();
I am developing a Web Service solution that is hosted inside a JBoss 4.2.3 sever (as the following) and my code connect to Remote JMS queue hat is hosted on another server(192.168.35.25)
public static Context getInitialContext () throws JMSException,NamingException
{
Properties prop = new Properties();
prop.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
prop.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");
prop.setProperty("java.naming.provider.url", "192.168.35.20:1099");
Context context = new InitialContext(prop);
return context;
}
public String SendMessages(String msg) throws ServletException, IOException, URISyntaxException {
String body="";
try
{
Context init =ClsSat.getInitialContext();
javax.jms.Queue destination = (javax.jms.Queue) init.lookup("Queue/RemoteQueue");
ConnectionFactory connectionFactory = (ConnectionFactory) init.lookup("ConnectionFactory");
Connection connection = connectionFactory.createConnection("un","pwd");//
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
;
MessageProducer producer = session.createProducer(destination);
TextMessage message = session.createTextMessage();
message.setText(msg);
connection.start();
producer.send(message);
body = message.getText();
session.close();
connection.close();
}
catch (Exception e)
{
return(e.toString());
}
return body ;
}
But I got an error ... RemoteQueue not bound
so any one have an idea or help about connect to remote queus throw web service
or any documents about connect to Remote queue on remote machine from web service hosted on local machine
Can it be because of the wrong IP address in your getInitialContext(), please check if not you can provide some more detail.
