Scenario: From browser will call RestService- A and this A service internally calls another RestService-B. URL used in browser will have some parameters which are passed to RestService-B.
Q1. How to call service-B from service-A using java RESTEasy API?
Q2. How to pass URL's parameters to service-B from service-A?
In service-A, wrote "RestEasy client code" accessing resource/service exists in service-B. From Browser(Firefox), service call(URL) to service-B.

Am receiving the message "System.Net.WebException: The HTTP request was forbidden with client authentication scheme 'Anonymous'." when trying to call the web service at "https://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.php" using BizTalk 2013.
I've imported the wsdl directly from the site, creating the schemas and the bindings to make the call. The Send port is set up as WCF-BasicHttp, Security Mode: Transport, Transport Client Credential Type: None. I'm able to call the service using SOAP-UI from the BizTalk server, providing no form of authentication.
Have read numerous posts and documentation, but nothing I've done to this point has helped. I'm sure I'm missing something; just not sure what that something is!
From the looks of the WSDL: <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> it's an RPC type web service
Like the documentation specifies: 'The WCF adapters do not support consuming Remote Procedure Call (RPC)-style Web services because the message parts in RPC-style Web services are referring to the message types rather than the message elements where WCF adapters are using elements for the message parts. We recommend that you add the RPC-style Web services through Add Web Reference wizard for consuming the Web services in BizTalk projects.'
In my project I need to write a web service which will receive Collection<?> as a parameter.. I am using apache CXF.. After I have written the service method I am unable to test it using SOAP UI (It is not generating any request).. My question is - Is it possible to receive Collection<?> over web service? I need to receive Collection of any object type.. Please help..
You need to work directly with SOAP messages.
I have two servlets that access two corresponding Axis2 web services on the same host. One of the servlets is read-only, while the other writes to a database.
Each of the Axis2 web services uses BASIC authentication. The read-only web service uses a system account, while the write web service uses the user's credentials (which are submitted as part of a web form).
The problem I'm running into is that the servlet called second always fails authentication to its web service. For example, I can query the read-only service through it's servlet all I want, but I get a "401: Authorization Required" when I try to use the write service. If I call the write service first, I get the same error when I try to use the read-only service.
Here is how I am setting the credentials for the connections in the servlets:
Stub service = new Stub(serviceUrl);
HttpTransportProperties.Authenticator auth = new HttpTransportProperties.Authenticator();
auth.setUsername(username);
auth.setPassword(password);
auth.setPreemptiveAuthentication(true);
service._getServiceClient().getOptions().setProperty(HTTPConstants.AUTHENTICATE, auth);
The servlet that accesses the read-only service has this code in it's constructor. The servlet that accesses the write service has this code in it's doGet/doPost method.
It seems that the credentials for the first service called are getting cached somewhere, but I can't find where that could be. I saw a possible solution here, but I can't find where WSClientConstants.CACHED_HTTP_STATE is defined. The comments in this JIRA issue seems to imply that it's part of org.apache.axis2.transport.http.HTTPConstants but it's not there.
Specifics:
Axis version: 1.5.1
Tomcat Version: 6.0.26
Java version: 1.6.0_23
It turns out the connections to the two different services were using the same JSESSIONID. Thus, the connection to the second web service was trying to use a session authenticated for the first web service, causing the error.
My solution for this was to define an HttpClient for each service, done by the following
MultiThreadedHttpConnectionManager manager = new MuliThreadedHttpConnectionManager();
HttpClient client = new HttpClient(manager);
ConfigurationContext context = ConfigurationContextFactory.createDefaultConfigurationContext();
context.setProperty(HTTPConstants.CACHED_HTTP_CLIENT, client);
context.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, true);
Stub service = new Stub(context, serviceUrl);
This allows both servlets to have a separate session for their corresponding services.
The important point is to create a dedicated ConfigurationContext.
I've solved in a simpler way using a default config context when creating the stub without the multithreaded connection factory
stub = new MyStub(ConfigurationContextFactory.createDefaultConfigurationContext(), myServicesUrl);
How can i call a restfull web service by a web browser if i have complex objects like hashmap or arraylist on the server side.I have found sample java clients but no help for doing it from web browser..
For instance if my web service waiting an arraylist of string objects how to differentiate this from a service which expects more than one string parameters on the input url.
That very much depends on what the server accepts as the body of your HTTP request and what it can return. In REST, there is no such thing as a List of Strings. You pass and receive Representations of Resources.
So what are your Resources? What are their Representations?
I have different Spring Web Services, which are included into the context by the
Endpoint Annotation, so there are no dependencies despite the Annotation (no interface etc.). Therefore, no "context" information is present.
Now I want to chain a web service request, ie. an Endpoint is called which itself should call a web service on the same server. I can use Spring's WebServiceTemplate, however, I need the current server url for this request.
Is there any way how this url can be injected during application startup into the Endpoints? Since the Endpoints do not extend some class, there is no way to get this information anywhere inside the Endpoints, also the request parameters do not have this information (these are simple JAXB-classes, which are marshalled on request).
I believe the best option is to send the URL as part of the request.
This also enables you to dynamically change the URL to a third server later.
