Web service Soap getting Read Timeout Exception - apache

I am trying to create soap web service client by one client WSDL file by using Apache Axis 2 and tomcat 6.
I successfully generated client, but when I am calling methods to get data I am getting error.
WSDL location: https://staging2.myhcl.com/MedicalClaim/Service.svc?wsdl
Error:
Unable to sendViaPost to url[http://staging2.myhcl.com/MedicalClaim/Service.svc]
java.net.SocketTimeoutException: Read timed out
My doubt is mentioned below:
We are sending request with GET or POST methods that how we can know in SOAP web service?
When above mentioned error used to come?
Rather than Apache Axis 2, what other generating client can we use for this WSDL file?

You might need to check how much time it is taking at Skeleton end.I have done SOAP some time back and i have faced same issue.Below code might help you
private HttpURLConnection getConnection(String endPoint) {
try {
URL url = new URL(endPoint);
URLConnection connection = url.openConnection();
connection.setConnectTimeout(20000); // 20 sec connection timeout
connection.setReadTimeout(60000); // 60 sec read timeout
HttpURLConnection httpConnection = (HttpURLConnection) connection;
httpConnection.setRequestMethod("POST");
OutputStream out = httpConnection.getOutputStream();
return httpConnection;
} catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
But ensure that your service(Skeleton) is not taking much time to process the request.You can use SoapUI to find out how much time it is taking to return the response.Accordingly you can set the timeout value.
Here comes answers of your doubts:
1.You can set POST/GET in HttpURLConnection object.
2.The error specified can come if the connection is idle for long and the Service is not returning any result.Use SoapUI to check the reply from Service.
3.wsdl2java and java2wsdl with Apache Axis2 is a good option for this purpose.Also xmlbeans has an inbuilt converter, which is quite handy to use.

IllegalArgumentException: "Auth scheme may not be null" in CloseableHttpAsyncClient

I'm running some asynchronous GET requests using a proxy with authentication. When doing HTTPS requests, I'm always running into an exception after 2 successful asyncronous requests:
java.lang.IllegalArgumentException: Auth scheme may not be null
When executing the GET requests without a proxy, or using http instead of https, the exception never occurred.
Example from Apache HttpAsyncClient Examples
HttpHost proxy = new HttpHost("proxyname", 3128);
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(proxy), new UsernamePasswordCredentials("proxyuser", "proxypass"));
CloseableHttpAsyncClient httpClient = HttpAsyncClients.custom().setDefaultCredentialsProvider(credsProvider).build();
httpClient.start();
RequestConfig config = RequestConfig.custom().setProxy(proxy).build();
for (int i = 0; i < 3; i++) {
HttpGet httpGet = new HttpGet(url);
httpGet.setConfig(config);
httpClient.execute(httpGet, new FutureCallback<HttpResponse>() {
public void failed(Exception ex) {
ex.printStackTrace(); // Exception occures here afther 2nd iteration
}
public void completed(HttpResponse result) {
// works for the first and second iteration
}
public void cancelled() {
}
});
}
httpClient.close();
If I run the code above with 'http://httpbin.org/get', there is no exception, but if I run it with 'https://httpbin.org/get', I get the following exception after 2 successful requests:
java.lang.IllegalArgumentException: Auth scheme may not be null

Note: I'm using httpasyncclient 4.1.4
If this is the exact code you have been executing then the problem is quite apparent. Welcome to the world of even-driven programming.
Essentially what happens is the following:
The client initiates 3 message exchanges by submitting 3 requests to the client execution pipeline in a tight loop
3 message exchanges get queued up for execution
The loop exits
Client shutdown is initiated
Now the client is racing to execute 3 initiated message exchanges and to shut itself down at the same time
If one is lucky and the target server is fast enough one might get all 3 exchanges before the client shuts down its i/o event processing threads
If unlucky or when the request execution is relatively slow, for instance due, to the use of TLS transport security, some of message exchanges might get terminated in the middle of the process. This is the reason you are seeing the failure when using https scheme but not http.

Rally Java Rest API 302 Temporarily Moved Error

I am creating a integration tool for TeamCity to Rally and using the Java REST API. When I try to create an object of type "build" I get an exception thrown by the restAPI with a 302 "temporarily moved" error.
How do I handle this? I cannot see any settings in the Rally RestAPI that turns on or off redirects and the API is not handling the redirect.
Any suggestions?
Here is the code that is being issued. The create call to the restAPI throws an exception. The two calls to def.getWorkspace().getRef and def.getRef() return the URLs for the workspace and build definition entries which this build record is associated with (the string is the "_ref" attribute from those entities).
try {
JsonObject obj = new JsonObject();
obj.addProperty("workspace", def.getWorkspace().getRef());
obj.addProperty("buildDefinition",def.getRef());
obj.addProperty("duration",1.05);
obj.addProperty("message", "Message for the build");
obj.addProperty("number","TEST0000");
obj.addProperty("start", isoFormat.format(new Date()));
obj.addProperty("status","Passed");
obj.addProperty("uri", "http://teamcity.com");
CreateRequest request = new CreateRequest("build", obj);
request.setFetch(new Fetch("FormattedID,Name"));
CreateResponse response = restAPI.create(request);
} catch (Exception e) {
LOG.error("Could not create object of type: " + type, e);
}
Have you successfully been able to create other objects/artifacts? Do you know if you have a Proxy server? It's possible that the 302 is coming from an intermediate Proxy rather than Rally. If you have a proxy, you can do:
restAPI.setProxy("https://myproxy","myproxyuser","myproxypassword");
To setup a proxy for your REST connection. Aside from that, a couple of comments:
Valid values for "Status" are [SUCCESS, FAILURE, INCOMPLETE, UNKNOWN, NO BUILDS]
There's no need to do a setFetch on a CreateRequest - the Fetch parameter is only used for Queries.
I hope this helps.

WCF Relay not receiving messages

I have several queues on the Azure service bus and are now setting up a WCF relay service (inhouse) for processing messages. I have written a console application that hosts this service and looks like this:
var sh = new ServiceHost(typeof(MyWcfService));
try
{
sh.Open();
foreach (var endpoint in sh.Description.Endpoints)
Console.WriteLine(String.Format("Listening at: {0}", endpoint.Address));
Console.Write("Press ENTER to close");
Console.ReadLine();
}
catch (Exception e)
{
...
}
finally
{
sh.Close();
}
MyWcfService is implementing an interface with the method
[WebInvoke]
[OperationContract]
void ProcessMessage(IntegrationMessage message);
When executed, I get messages that tells me that the application is listening to three different sevicebus endpoints (which are the ones I have configured) so this seems to be correct.
When looking at the traffic through Fiddler I get only 4 rows:
200 HTTP Tunnel to xxx-sb.accesscontrol.windows.net:443
200 HTTPS xxx-sb.accesscontrol.windows.net /WRAPv0.9/
200 HTTPS xxx-sb.accesscontrol.windows.net /WRAPv0.9/
200 HTTPS xxx-sb.accesscontrol.windows.net /WRAPv0.9/
which in my eyes seems correct as it returns 200 and I see in fiddler that it also return a wrap_access_token..?
The question is why are there not any additional requests for getting the actual messages? I was expecting additional calls to open the connection to the service bus, but none are made..
I know that there are messages on at least two of the three queue's.
Any help will be much appreciated, and I will provide more information if needed.

Openning Async WCF Service with wrong Username-Password hangs

I have a WCF service that implements the 'Custom-Username-Password-Validator'.
The service itself checks the username+password against a local file,
and if there is no match - it throws a FaultException with a message.
.
When I use the service synchronously it works fine.
When I go to work with it ASYNC, I have a problem.
If I pass the wrong 'Username+Password' credentials - and open the client,
instead of returning immediatly from the service going into my 'Channel_Faulted()' method,
the client thread simply waits until the Timeout triggers,
and then I get a 'TimeoutException'.
try
{
client = new MyServiceClient("WSDualHttpBinding_IMyervice");
client.ClientCredentials.UserName.UserName = "username";
client.ClientCredentials.UserName.Password = "bad password";
client.ChannelFactory.Faulted += new EventHandler(ChannelFactory_Faulted);
client.Open(); // This hangs for 01:00:00 minute
// Doesn't reach here
client.DoSomethingCompleted += new EventHandler<DoSomethingEventArgs(client_DoSomethingCompleted);
client.DoSomethingAsync(param);
}
catch (Exception ex)
{
// Enters here with a 'TimeoutException' exception
}
why does the client not trigger the 'Faulted' method I have ?
Why does it wait for a response from the service even though the service through a 'FaultException' during the 'Validate' method of the 'CustomUserNameValidator' ?
Sure, the code you are using appears to be missing 3 lines after your code line:
client.ChannelFactory.Faulted += new EventHandler(ChannelFactory_Faulted);
But again, I'm taking a shot in the dark since I've not made use of this option yet.
var local = client.ChannelFactory.CreateChannel();
((IClientChannel)local).Faulted += ChannelFaulted;
local.Open();
Better yet, the open method doesn't appear to be necessary according to the sample provide here: ChannelFactory
I personally have not used the ChannelFactory.Faulted event handler however, here is a post for your consideration: creating-wcf-channelfactory

Retrieve WCF Rest Response in Client

I'm using the WebChannelFactory<> to create a channel and interact with a WCF REST Service.
When there is an error, I want to retrieve the response from the channel to read the error message from the body of the response. But I cannot figure out how to get the response stream.
Here is my code:
using (var cf = new WebChannelFactory<T>(new Uri(url)))
{
var channel = cf.CreateChannel();
using (new OperationContextScope(channel as IContextChannel))
{
WebOperationContext.Current.OutgoingRequest.Headers
.Add("x-st-authtoken", HttpUtility.UrlDecode(Constants.General_AuthorizedToken));
WebOperationContext.Current.OutgoingRequest.Headers
.Add("x-st-tesskey", HttpUtility.UrlDecode(Constants.General_SessionKey));
try
{
a(channel);
}
catch (Exception ex)
{
throw new Exception("Status: " + ((int)WebOperationContext.Current.IncomingResponse.StatusCode).ToString());
}
}
}
In the catch statement, I want to include the data from the Response body...
It seems like an obvious thing, but I can't seem to find any information on the internet or anything.
Is there any specific reason for you to use ChannelFactory to interact with the REST service. I think it is easier to use HttpWebRequest object to invoke the REST service and there you can get the respone stream when an error is throw on the server.
Also check out RestSharp API through which you can achieve your task to read the response stream.
I believe it will throw a WebException.
so if you explicitly catch that type you can get use the WebException.Response property (which is an HttpWebReponse) on the exception and you can get the content from its stream.
