Consuming 3rd party web service in Java web dynpro application

Hi All,
I am working on a scenario where external(3rd party) web service has to be consumed in WD Java application. I am provided with WSDL file. Let me explain how I usually consume other webservices:
     Create model->AWS model->Remote Location/file System->provide url->create/choose service group->finish
     Then I would generate the code in custom controller by applying template
      I assign provider system as local for the service group in nwa.
This is normal process to me. I am struck with this 3rd party web service. Please share your ideas on the same. Any help is highly appreciated.
BR,
Manoj

I ve created a provider system pointing to where 3rd party WS resides. i am trying to connect through WSIL. While pinging that provider system, I don't see that particular WS(that I am gonna consume). And while assigning this Provider system to service group, processing state getting 'Failed'.
What could be reason?

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you

Problem in calling XI generated Web Service via Java Web Dynpro

Hi experts,
I have problems with calling a web service, which was created by XI. I have already tested the web service with Altova XMLSpy. The Web Service works fine.
But when embedding this web service into Java Web dynpro application no message flow is given. I have two views one Selection View and one Result View which should show the answer sent by RFC-Call.
My Settings in NWDS:
During configuration of web dynpro I have choosen 'Import adaptive Web Service Model' --> Select wsdl file via local file system --> 'no logical destinations - use WSDL URL for metadata retrieval and web service execution'.
The model is also not shown in diagram view although I have added into the diagram.
The web service was created on XI 7.0.
Should I do any other settings e.g. in Visual Administrator, Web Dynpro Content Administrator?
So can anybody help me.
Thanks a lot.
Regards,
Mario

Hi Aviad,
thanks for your fast reply.
But in Web Service Navigator my Web Service is not shown, because I used the SOAP Adapter.
My Web Service link:
http://<host>:<port>/XISOAPAdapter/MessageServlet?channel=:SRV_GBD_WS_GET_DEB_DETAIL:CC_GBD_WEBSERVICE_SENDER&version=3.0&Sender.Service=&Interface=%5E*
During executing Web Dynpro I got following errors:
1. 'The system cannot find the path specified'.
2. com.sap.tc.webdynpro.model.webservice.exception.WSModelRuntimeException: Exception on creation of service metadata for WSDL URL

JDeveloper 10g 10.1.3 Web Service Question: java web service calls another

I am looking for what I think should be a simple example/tutorial but so far no luck. I am using JDeveloper 10g 10.1.3 and the Oracle Application Server.
I want to do this:
- create a simple Java web service
- deploy it
- create another simple Java web service, that makes a call to a method on the first service
- deploy it
client->WSfront->WSback
I want to keep this as basic as possible.
Although I have found examples of how to create a web service proxy, there are no examples that I have found that show how to use that proxy in another web service:
I did what I thought were the right things; generated a proxy for the first web service, and used that proxy in the second web service's source Java class. However when I deployed and tested many classes were missing: all the classes the proxy class depends on.
I actually managed to get something like this working but had to manually create the .ear and .war files for WSfront, explode the archives, and manually add the missing classes to its WEB-INF/classes.
I am comparing this to things like Weblogic Workshop in which doing this exercise is a snap.
Is there a simple graphical way to do this in JDeveloper?

Hello again,
I am quite surprised I got no responses to my query below.
Can anyone explain how I might do this?
Please feel free to respond to [email protected]

401 Error on Consuming SharePoint Versions Web Service by java client running on Unix Machine

In my organiszation I have sharepoint site of our project. I have a java client to consume Versions Web Service offered by SharePoint. The response received from web service without any issue when triggered from a client running on windows machine on

When same java client ran from UNIX server on same intranet, it gives 401 error. Is there some different approach required for authentication while connecting from unix machine?
Thanks in advance.

Hello,
Are you passing credential in code? If not then try to add using networkcredential.
If you are passing then make sure that current user is having access on SP site and your javaserver is setup for NTLM security. Here is few links for same issue which could help you troubleshoot the issue

Thanks for the reply !I have read a lot of things about web service. i m reading about a week now for web services :)Well, you probably won't be able to do it with just a week of reading.Maybe a "hello world" type of webservice producer + consumer, if you know Java and web environments properly. JAX-RS is a bit easier in my opinion though, its a very well-defined API and I had a setup between Java and Ruby on Rails running in an afternoon. If you take the time to read and understand the material first of course. Especially the understanding part is what people tend to want to skip over.
We can't just "give a hint" and you'll be magically able to write a webservice. Programming doesn't really work that way.Indeed, and software engineering works even less like that. It happens to be bloody hard.

Cosuming Web Service in Java

Hi,
How would I consume web service using Java SE ?
Is there any lib i can use ?
import.java.net or something ....
Any input will be good.

Creating a web service client means first setting up your environment and making a few decisions about which of the available invocation methods is best for your application.
Have a look at the following links for some pointers:
http://www-128.ibm.com/developerworks/webservices/library/ws-javaclient/
http://java.sun.com/blueprints/guidelines/designing_webservices/
Investing in a decent web services book, like the following, is also a good idea:

I tried to modify abit the code as i changed the web method parameter from object (BatchOrder order) to variables(eg. int) and it works. When I test the Web Services I need to select the include checkbox den it works nicely else i will also encounter this problem. Does this mean the web services can not take it object as parameter?

Hi Paolo,
maybe I faced the same issue. I solved it reading the thread:
web service deployable client
Hope this help

2. The .NET Web Service is available online. (It is made by other people).
3. Based on the equation, what is the equivalent technology for the + sign?
4. Can you site a concrete example for accessing a web service?
5. I'm new here. Totally I have no idea where to start.
6. Thank you experts.

Hello
Thanks a lot for your help ...
I am developing simple J2EE based web service client using IBM WSAD 5.1. I have used the following code to call .asmx web service in Java
String url = "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl";
     String namespace = "http://tempuri.org/";
     name = request.getParameter("txtName");
     try
          System.out.println("In Internet Service");
          ServiceFactory factory = ServiceFactory.newInstance();
          Service serv = factory.createService(new URL(url),new QName(namespace,"TempConvert"));
          System.out.println("Got Service......");
          Call obj = (Call)serv.createCall();
          System.out.println("Got Call......");
          obj.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY,"");
          obj.setProperty(Call.OPERATION_STYLE_PROPERTY,"wrapped");
          obj.setTargetEndpointAddress(url);
          obj.setPortTypeName(new QName(namespace,"TempConvertSoap"));
          obj.setOperationName(new QName(namespace,"FahrenheitToCelsius"));
          obj.addParameter("param1",XMLType.XSD_STRING,String.class,ParameterMode.IN);
          obj.setReturnType(XMLType.XSD_STRING);
          System.out.println("Parameters Set.....");
          Object[] params = new Object[]{name};
          k = (String)obj.invoke(params);
          System.out.println("Result: "+k);
     catch(Exception e)
        System.out.println("Exception is : "+e);
    }But this code is throwing exception that
Invalid Address "http://www.w3schools.com/webservices/tempconvert.asmx?wsdl"I have also tried this URL with Java Proxy. But it showing the same error.
Plz can u tell me how to access .asmx web service ?

Parse errors while creating a Web service from Java class!

Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
"Validation failed.
The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
import java.io.*;
import java.util.*;
class isPrime
public static void main (String args[])
Scanner reader = new Scanner(System.in);
int n;
System.out.println ("Enter a number you want to know is it prime or not");
n=reader.nextInt();
if (isPrime(n))
System.out.println ("True");
else
System.out.println ("False");
static boolean isPrime (int n)
int i=2;
while (i<=n-1)
if (n%i==0)
return false;
i++;
return true;
}

Hi,
Can anybody tell me please, is it possible to create
a Web Service from java class where the input from
user is required ?Yes, the parameters of your method will be mapped in WSDL.
But i've some considerations about your code.
I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
Regards.

Calling a Web Service from Java

Our java guru (who is out sick....AHHHH) created all the calls that are needed to access the web service that he has running. For example the call getLongList(String user, String password) will return a list of all outstanding transactions. He made a jar file that has service has class files for PortType, Service, Service Locator and Soap Binding stub.
How do I call this web service from java? Do I have to import it into my classpath? or just call these parameters from within my java code?

never mind...i got it

Calling a Web Service from Java Webdynpro

Hi,
Can any one give me step by setp details on how to call a Web Service from Java Webdynpro ?
I tried creating a model using Import Web Service Model but when I completed creating the model, I got some errors as shown below.
Error The method setRouteGeometryLineArray(double[][]) in the type Trip is not applicable for the arguments (double[]) ComplexType_Trip.java WS_INVOKE/gen_wdp/packages/com/cintas/test/model/p1 line 249
thanks
SBK

Hi SBK,
I assume you may already have read the [help guide|http://help.sap.com/saphelp_nw70/helpdata/EN/81/12703e5da3e946e10000000a114084/content.htm] This gives a pretty good idea of how to do it (step by step).
Is there a typo in the error you pasted?
Error The method setRouteGeometryLineArray(double][) in the type Trip is not applicable for the arguments (double[]) ComplexType_Trip.java WS_INVOKE/gen_wdp/packages/com/cintas/test/model/p1 line 249
The square brackets [] after double in the method call appear to be reversed. Is that also in the code? or just a mistake here?
Hope this points you in the right direction.
BRgds,
Simon

Web Service From Java class, serialization problem

Hi,
I want to create Web Service from Java class, I made java project, generated web service from it, create web service archive project and deployed it to WAS 6.40.
My class have 2 methods,
public int add(int a, int b);
public MyResponse doSomthing(MyRequest req);
I can succesfully call add method from Web Service Navigator, it works fine but when I call doSomthing methods I get the following error:

Deserializing fails. Nested message: XML Deserialization Error. Result class [com.mycomp.sap_tech.ws.MyRequest] does not have property [Amount] of type [java.lang.String]. It is required to load XML..

Any ideas how to resolve it?
P.S. MyRequest class is exposed throw VI, has default constractor and public getters and setters for all properties. It implements Serializable as well. Any guesses?
Thanks in advance,
Victor.

Hi Bhavik, thanks for response.
as I already mentioned it implements Serializable, so it is not the problem.
Thanks Avi but it didn't helps iether
