Creating client for web service - web-services

I have deployed a simple hello service in jboss server. I can view the wsdl file. Can someone help me with the client side. I mean how to access this service? Is there any way to access from web browser? Method deployed is
#WebMethod
public String greet( #WebParam(name = "name")
String name )
{
return "Hello" + name;
}

Try to know what is the wsdl url to access the service which you have just exposed. It might most probably be something like "http://localhost: < port-number >/ems-ejb/?wsdl"
If you type the same in the browser, you should be able to see the wsdl file (page with full of xml tags).
Once done, follow the steps provided here
Example on how to call the method once client stub is generated
String endpoint = "your wsdl url";
GreetImplServiceLocator objGreetImplServiceLocator = new GreetImplServiceLocator();
java.net.URL url = new java.net.URL(endpoint);
GreetIntf objGreetIntf = objGreetImplServiceLocator.getFaultImplPort(url);
String greetings=objFaultIntf.greet("stackoverflow");

JWT Token Google Cloud Run

I am developing an application with JWT authentication on the google cloud platform. Server side I added authentication via Cloud API Gateway to a cloud run backend. Now I am making a client to generate the JWT token and pass it in the call. To do this I am creating an application that must be deployed on CloudRun and I am following this documentation: https://cloud.google.com/api-gateway/docs/authenticate-service-account#making_an_authenticated_request. My problem is that I don't know how to indicate what it requires as saKeyfile. I tried to put only the name of the file that under src / main / resources / filetest.json but once I try to call the method it tells me file not found. I tried to indicate also the full path. Can anyone help me?
PS I'm using Java
EDIT:
here is my code which is the same of documentation
public void makeCall() {
String fullPath="src/main/resources/TEST1-id.json";
String saEmail="testsa#projectID.iam.gserviceaccount.com";
String audience="auth";
int expiryLenght=600;
String token;
try {
token=generateJwt(fullPath,saEmail,audience,expiryLenght);
System.out.println("Token generated: "+token);
URL url = new URL("apigatewayurl");
makeJwtRequest(token, url);
System.out.println("Call performed");
} catch (IOException e) {
e.printStackTrace();
}
}
private static String generateJwt(final String saKeyfile, final String saEmail,
final String audience, final int expiryLength)
throws FileNotFoundException, IOException {
Date now = new Date();
Date expTime = new Date(System.currentTimeMillis() + TimeUnit.SECONDS.toMillis(expiryLength));
// Build the JWT payload
JWTCreator.Builder token = JWT.create()
.withIssuedAt(now)
// Expires after 'expiraryLength' seconds
.withExpiresAt(expTime)
// Must match 'issuer' in the security configuration in your
// swagger spec (e.g. service account email)
.withIssuer(saEmail)
// Must be either your Endpoints service name, or match the value
// specified as the 'x-google-audience' in the OpenAPI document
.withAudience(audience)
// Subject and email should match the service account's email
.withSubject(saEmail)
.withClaim("email", saEmail);
// Sign the JWT with a service account
FileInputStream stream = new FileInputStream(saKeyfile);
ServiceAccountCredentials cred = ServiceAccountCredentials.fromStream(stream);
RSAPrivateKey key = (RSAPrivateKey) cred.getPrivateKey();
Algorithm algorithm = Algorithm.RSA256(null, key);
return token.sign(algorithm);
}
i've tried to use full path like in example and using only /TEST1-id.json
and here there is project structure. Is a springboot application which i will deploy in cloud run
The OP fixed the issue on this way
In the end I put the file in the root and copied it in the docker image and recover it as an environment variable in cloud run

simple azure web service, http404 error on publish when adding /dowork to URL

I am trying my first web app service using Azure services. I've created it in VS, and it works locally. All it does it return a string that says "hello user" is JSON.
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{
// To use HTTP GET, add [WebGet] attribute. (Default ResponseFormat is WebMessageFormat.Json)
// To create an operation that returns XML,
// add [WebGet(ResponseFormat=WebMessageFormat.Xml)],
// and include the following line in the operation body:
// WebOperationContext.Current.OutgoingResponse.ContentType = "text/xml";
[OperationContract]
[WebGet(UriTemplate = "/DoWork")]
public string DoWork()
{
// Add your operation implementation here
return "hello user";
}
// Add more operations here and mark them with [OperationContract]
}
}
Problem is when I publish it, says successful. I can see it running on portal.
When I goto published site I get the standard THIS WEB APP HAS BEEN SUCCESSFULLY CREATED, but... when I add the /DoWork to the URL I get HTTP error 404.
I know I must be missing something simple...
any ideas?
you're missing the name of the service. In your case would be something like:
http://engineappservicev001.azurewebsites.net/something.svc/dowork

Unable to set headers in apex web service callouts in salesforce

I'm currently trying to call Amazon Product Retail Web Service in Salesforce.
As I mentioned in
Getting WSDL parse error while generating Apex code from WSDL in Salesforce
I was initially unable to generate apex stub class, but I followed the method suggested by #Ballinger and created apex class. I wrote an apex class to use that stub and to set request parameters. The class i wrote is as follows
public class AmazonProductStubNew
{
public static void getResults()
{
System.Debug(' getResults start ');
AmazonWS.AWSECommerceServicePortUS stub = new AmazonWS.AWSECommerceServicePortUS();
stub.inputHttpHeaders_x = new Map<String,String>();
stub.inputHttpHeaders_x.put('AWSAccessKeyId','MyAmazonAWSAccessKeyId');
stub.inputHttpHeaders_x.put('Timestamp','2012-11-28T12:11:30Z');
stub.inputHttpHeaders_x.put('Signature','Encrypted Secret Code');
String MarketplaceDomain = '';
String AWSAccessKeyId = 'MyAmazonAWSAccessKeyId';
String AssociateTag = '';
String XMLEscaping = '';
String Validate = '';
AmazonWS.ItemSearchRequest Shared = new AmazonWS.ItemSearchRequest();
Shared.SearchIndex = 'DVD';
AmazonWS.ItemSearchRequest[] Request = new AmazonWS.ItemSearchRequest[1];
Request[0] = new AmazonWS.ItemSearchRequest();
Request[0].Title = 'Inception';
AmazonWS.ItemSearchResponse_element response = stub.ItemSearch(MarketplaceDomain,AWSAccessKeyId,AssociateTag,XMLEscaping,Validate,Shared,Request);
AmazonWS.Items_element[] localItems = response.Items;
System.Debug(localItems[0].TotalResults);
}
}
Even though I've added HTTP headers to stub, I'm not getting it in XML Request message
XML Request is as follows
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<env:Header />
<env:Body>
<ItemSearch xmlns="http://webservices.amazon.com/AWSECommerceService/2011-08-01">
<MarketplaceDomain>
</MarketplaceDomain>
<AWSAccessKeyId>MyAWSAccessKeyId</AWSAccessKeyId>
<AssociateTag></AssociateTag>
<XMLEscaping></XMLEscaping>
<Validate></Validate>
<Shared><SearchIndex>DVD</SearchIndex></Shared>
<Request><Title>Inception</Title>
</Request></ItemSearch>
</env:Body></env:Envelope>
Since headers are not there in SOAP Request, There is a SOAP fault asking for Signature from Amazon Server.
As you can see, I'm new to Salesforce Apex. I followed the steps in
http://www.salesforce.com/us/developer/docs/apexcode/index_Left.htm#StartTopic=Content/apex_web_services_wsdl2apex.htm#http_header_support
to set the headers.
Any idea on why the header isn't getting added?
P.S I added headers manually and tried in SOAP UI, I'm getting proper response.
Thanks :)
I think you're using wrong functions :) (question is indeed confusing).
SOAP (or generally HTTP) communication consists of sending headers and actual message (payload if you like). Headers are short text thingies, message is often a giant XML.
Your code is setting HTTP headers (which are used in web communication to authenticate, provide info about your browser, preferred languages, set cookies, return status codes like 404 page not found...) Please don't be offended with the "for dummies" but I realize the wikipedia article is a bit too much, this might be simpler: http://net.tutsplus.com/tutorials/other/http-headers-for-dummies/
And what I suspect Amazon's webservice wants is just some fields inside the <env:Header>...</env:Header> tag? Just check the generated apex code for existence of subclass called "Header" (you can also search for the variable names like "Signature". This is going to be a total wild guess but I think you'll have to write something like that:
AmazonWS.AWSECommerceServicePortUS stub = new AmazonWS.AWSECommerceServicePortUS();
AmazonWS.Header h = new AmazonWS.Header();
h.AWSAccessKeyId = 'MyAmazonAWSAccessKeyId';
h.Timestamp = '2012-11-28T12:11:30Z';
h.Signature = 'Encrypted Secret Code';
stub.Header = h; // plug it into the request
// create and plug other required tags
AmazonWS.ItemSearchRequest Shared = new AmazonWS.ItemSearchRequest();
Shared.SearchIndex = 'DVD';
AmazonWS.ItemSearchRequest[] Request = new AmazonWS.ItemSearchRequest[1];
Request[0] = new AmazonWS.ItemSearchRequest();
Request[0].Title = 'Inception';
// ...
Now, to make it more confusing you might still have to use a HTTP header, there's a special one called SOAPAction. But generally speaking I believe you're after placing your data in the XML, not in http headers.
Funny enough, I've downloaded the Java example from http://aws.amazon.com/code/Product-Advertising-API/2478 and if I read it correctly they're passing the signature in the URL (endpoint), not in the XML. Probably because it's a REST GET method (if you can access that API it could save you a lot of hair pulled, SOAP is clunky).

Authentication failure calling SharePoint Web Service (JAX-WS client)

I have to call SharePoint 2010 Lists service from a Java client.
I used NetBeans to generate the JAX-WS classes from the WSDL.
And extended java.net.Authenticator to manage the authentication to SharePoint :
static final String user = "XXXXXXXX\\Administrateur"; // your account name
static final String pass = "mypassw"; // your password for the account
static class MyAuthenticator extends Authenticator {
public PasswordAuthentication getPasswordAuthentication() {
System.out.println("Feeding username and password for " + getRequestingScheme());
return (new PasswordAuthentication(user, pass.toCharArray()));
}
}
Calling the web service with JAX-WS :
Authenticator.setDefault(new MyAuthenticator());
com.nm.Lists service = new com.nm.Lists();
com.nm.ListsSoap port = service.getListsSoap12();
String pageUrl = "http://xxxxxxx/testPushFile.txt";
String comment = "no comment";
String checkinType = "1";
boolean result = port.checkInFile(pageUrl, comment, checkinType);
I am still getting the error :
Exception in thread "main" javax.xml.ws.WebServiceException: java.io.IOException: Authentication failure
at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.readResponseCodeAndMessage(HttpClientTransport.java:201)
Because it isn't working I tried :
to set the user without the domain
to set the domain as a system property : System.setProperty("http.auth.ntlm.domain", "XXXXXXXX");
to authenticate "old-fashioned way" :
((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, user);
((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, pass);
Any ideas what's the problem with authentication ?
Thanks
I am coming back to give the solution. Here is what I have done to make the Web Service authentication work :
I enabled Basic Authentication in IIS Manager for my SharePoint Site,
I used a user credentials that was registred in Windows Domain

JavaFX applet communicating with server

I want to write some page with JavaFX applet. I want content on the applet to be dependent on user logged in.
I know I can call web services from JFX, but then what about login and session? Besides I think there might exist some better solutions for such communication than calling from applet a web service sitting on the machine applet comes from.
How can I do it?
You can build a servlet which returns the name of the logged in user.
Then in javafx you can use the class javafx.io.http.HttpRequest to call the servlet and read out the username. (The API also has some examples of how to use the HttpRequest)
The following javafx code prints out the return string of a Servlet:
var response: String;
def myRequest: HttpRequest = HttpRequest {
location: "http://localhost:8080/demo/foo.do";
method: HttpRequest.GET;
onInput: function(is: java.io.InputStream) {
var buff: StringBuffer = new StringBuffer();
var reader: BufferedReader
= new BufferedReader(new InputStreamReader(is));
var data: String;
while ((data = reader.readLine()) != null) {
buff.append(data);
}
response = buff.toString();
reader.close();
println(response);
}
};
myRequest.start();
EDIT: You should also take a look at this article: http://blogs.oracle.com/warren/entry/authenticating_a_javafx_application_using which shows how to access the html document and cookies from within the applet which resides on the document. That should be a very interesting approach for authentication.
