Consuming webmethods webservice

I have a simple issue for which I am not able to figure out the solution.
We have a webservice created in webmethods that needs to be consumed in CE portal. In dev CE server, I want to consume the Dev webmethods webservice, while in production I want to consume the production webemthods w.s.
The issue comes in the WSDL url changes from webmethods dev to webmethods QA and so does the WSDL.
What is the best practice around it to consume the appropriate WSDL?
Regards,
Nitin

John,
I have published the w/s in dev Service registry and consumed it in dev. so the design time wsdl URL reads the dev SR. When I moved to QA, at runtime, the application was still pointing to the dev SR.
However one catch, I was not able to setup SR in QA for QA webmethods for some server reasons. I expected system to throw errors but it instead started pointing to dev SR.
I have configured SR in production, but I am confused if the application will point to dev SR or prod SR.
Also, I tried consuming the WSDL by creating the Webservice Destinations, I could never get that working. Always got error in Medadata Destination.
Any reference material you have around it?
I have consumed WSdestinations in NW 7.0 without any problems.

Problem while Consuming Java Webservice from WCF client

Hi,
I am trying to Consume Java Webservice from WCF client.The webservice main functionality is digital data management.The client can Query Digital data and upload digital data by calling webservice methods.Problem is when i am trying to call webmethod from WCF client its giving "Unrecognised message versions".I have no idea about how the message objects are processed at serverside.but at server side they have used JAXP for XML document parsing.
The response content type is Multipart/related and applicatio/XOP+XML.
Can u plz help me how to handle this situation.I have minimum knowledge in Java WS architecture.Basically i am .Net programmer.
Can U please guide me in a proper way to resolve the problem.

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
The result of the WS is correct!!!
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?
Thanks

Consuming a webservice in ABAP ECC 6.0 without using XI/ PI

Hi Experts,
I wanted to consume an external webservice without using XI / PI.After doing my homework and search on sdn I came to know that we can consume webservices in ABAP using proxies using SE80(Enterprise Services).
I am trying to create a client proxy with the URL of webservice.It asks me the option to choose between URL or HTTP.
I am selecting URL and in the second screen it asks about the package details and after that it finishes.Later I get an error message stating "NO VENDOR SPECIFIED".Its not allowing me to create a proxy.
So, here are my questions.
Does anyone faced the same kind of problem?
Can we really consume a webservice without using XI / PI or any other middleware?
Is it possible to consume the webservice only with URL or WSDL file ?
Please let me know the exact process.
Thanks in Advance.
Shanker Pandey.

Hi,
I am still having the same problem, however the scenario in which I am getting varies.
I am getting this exception:
"com.sap.engine.services.webservices.jaxm.soap.accessor.NestedSOAPException: IOError while working with the message."
Some users when trying to login into the portal are getting blank screen and for some the portal launcher page is loading fine and could go to the Home Page.
When I view the logs I am seeing the Nested Soap Exception.
Any Ideas??? Starting the J2EE engine also did'nt help.

Error While Consuming the webservice in ABAP

Hi,
I am trying to consume a webservice in ECC. I have imported the WSDL and generated the proxy. Did the configuration in the SOAMANAGER. While calling the webservice from the program I am getting the following error message. "SRT: Unsupported xstream found: ("HTTP Code 400 : Bad Request")"
Any help is appreciated.
Thanks
Raghavendra Kuamr

Hi,
Check ST11 to find detailed log of issue, most likely you are passing "WS-A" message id along with request (check settings in SOAMANAGER Logical Port).
Try calling service after suppressing "Message Id transfer". See SAP Note: 1361688 and related notes in 0001292171

While Consuming a WebService in JSP Dyn Page - There is an Error

Hi Friends,
I have a web service created in ASP.NET web Service.
And I have Consumed the Web Service using WSDL URL.
I need to write a code to refer that class in the JSP DynPage
I have created like this in DoIntialization
MyServiceName obj=(MyServiceName) PortalRuntime.getRuntimeResources().getService(MyServiceName.KEY);
int a = 10;
int b = 20;
obj.Add1(a,b);
but it shows an error
"The method Add1 Method(Add1 Method) is the type. MySErviceName is not Applicable for the arguements(int,int)"
Please Help me in this regard.
Thanks in Advance
Thanks & Regards,
Palani

Hi Andy,
I will let u know the sequence which i followed to consume the Webservice.
NWDS --> File --> New --> Project --> Portal Application --> Create New Portal App Project.
The Project is created.....
After that i want to consume the Webservice for the same project...
for that...
NWDS --> File --> New --> Other --> Portal Application --> Create New Portal Application Object --> Selecting My Project?(intended prjct) --> Portal Webservice --> Portal Service from WSDL file - Client Side --> My WSDL URL --> Selecting the methods which i need to expose from the Webservice --> I gave unique name for my 1) Service 2) Alias 3) Package....and that was done....(other way is to add from portalapp.xml ??)
After that i created a new JSPDyn page for my application in DoInitialization() method i tried to access the method from that webservice using the following code...
MyServiceName obj=(MyServiceName) PortalRuntime.getRuntimeResources().getService(MyServiceName.KEY);
I am successfully able to access the method from the webservice using the object which i have created but i am not able to pass arguments to that method...???
I tried consuming same webservice created in .NET in .NET itself and i am able to pass arguments successfully.
I tried to consume webservice created in ABAP in .NET and able to implement successfully...
but the same ABAP webservice when i tried to consume its not working with this NWDS.
Is there any thing else i need to follow while consuming a webservice in the EP Perspectice of NWDS ???
Deployable Proxy is required for that ?? if required how to create and use that ??
Thanks in Advance,
Palani

What settings are reqd. for consuming a webservice in 6.2 - Other questions

Hi,
I have been following the below mentioned blog to create a program to consume a webservice.I am currently on Enterprise version(4.7), release 6.2.
I get a communication_failure(sy-subrc = 1) when using "METHOD http_client->receive".Please let me know if you have any solutions.(The code of the program is in the blog..link mentioned below)
Could the group provide solutions to the following in relation to blog mentioned below:
Webservice consuming using ABAP in 6.2
/people/durairaj.athavanraja/blog/2004/09/20/consuming-web-service-from-abap
- What Proxy settings are required to be performed,
where can we perform the same
- What is the information required to fill the user id
and passwords for ? - Are the credentials for the
webservice we are calling or for the proxy
(correct me if i am wrong)
- How can we fill the fields Proxy and port, how do they
play a role.
Thank you

Hi,
As reply to his blog DuraiRaj Athavan Raja has provided the following information.Thank you Raja.
http_client->receive - Communication failure obtained
2006-07-18 22:29:04 Durairaj Athavan Raja [Reply]
do you connect to internet via proxy? if yes you have to either code proxy authentication or simply maintain it in transaction SICF.
go to
SICF->client->proxy settings
go to http_log tab
host name: proxyhost.domain.com
port: <portno>
user - > proxy user id
pwd -> proxy pwd and save it .
and this setting is per client , so you have to do that for all clients.
Regards
Raja
I am working on getting the proxy settings completed and will update the post when i am through with all the findings.

Need to consume Beehive webservices but can't figure out the best way

Hi
I'm completely new to the Beehive scene and I've been commissioned to write a sample application that consumes Beehive Webservices, just add a File to a certain workspace and be able to authenticate users via SSO and basic Authentication to a local DB. Initially I was told that Beehive had only support for REST webservices, so I thought it might be just easier to just go with REST, do a simple POST/GET request and get results, however I'm having a hard time running the sample code as a class is missing.
However I just found that Beehive also has support for SOAP webservices (I somehow like them more as I'm more used to them) but same problem, I don't know how would I authenticate, I found were the WDSL are stored and everything but I just don't understand how would I make a user authenticate with SSO or any other method
Finalyl there's this BPEL workflow for jDeveloper and JCR API.
I just don't know where or how to start, tutorials are oracle.com assume too many things, I was thinking in creating proxy classes using the Beehive WSDL's and consume the services this way, however I still don't understand how to authenticate.
Can anyone give me directions on this? How to use Beehive's SSO and Basic Authentication? thanks in advance

Hi,
Regarding the basic http authentication, an answer was provided in your other post:
Authentication with SOAP API
And regarding the missing class in the Rest sample code. I'm currently taking a look at it and, hopefully, I will get you an update on this in the following post:

Consume a WebService that exists in SAP ECC 6.0

Hello evrybody,
I have a requirement that I've never done before, I have a webservice in transaction WSADMIN in a SAP ECC 6.0, and I need to consume it from PI but I don't know how, I've worked before with BAPI's and ABAP Proxies but never with WebServcies like this, do you know any documentation or maybe a blog on how to do this?, thanks in advance.
Regards,
Karla

Thanks for your answers, I've used ABAP Proxies before, but in the way of generating an ABAP Proxy of a Inbound or Outbound interface from the IR, now I need to consume a WebService already created in SAP ECC 6.0, and I've never donde this before, I'm trying to understand that using SOAP Adapter I should get the WSDL File of the webservice and upload as an External Definition in the IR, but where could I get the URL to consume the webservice that exists in SAP ECC 6.0, thanks.

Consuming external webservice in an automated activity

hi,
i am consuming a bapi based webservice in an automated activity. i have checked this in wsnavigator using WSDL, it is working fine. when i consume this in my process dc , it asks me to create aService group. i have created one and now deployed dc to server. it doesn't work and in log error it shows that thsi service group is not assigned to any physical system.
now i tried to create a business scenario communication, for this i created provider systems (it was created and pinged sucessfully, showed all the web services lying in its service registry). when i was creating business scenario, under first step credentials of service group and provider systems are provided. unser second step when i tried to add the services it didn't showed the services which it showed me while i pinged.
please tell me how to sucessfully consume an external web service (bapi based).This is lying on SR but when i tried to access it through single service administration, it was not there. please guide me how can i sucessfully consume this webservice (using service group or logical destination).
Thanks In Advance.

Hi Rohit,
try with Application Communication Configuration instead of Business Scenario (should be easier for single service). Make sure you have entered the correct credentials for the backend system (both for metadata retrieval and for runtime invocation).
Instead of Service Registry you can also try with WSIL when creating the provider system. The WSIL URL for the ABAP system should look like this: http://host:port/sap/bc/srt/wsil.
Please also check the SOA config guide by Alexander Zubev:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/40dabb46-dd66-2b10-1a9a-81aa620098b3
Hope this helps,

Consuming XI webservice in Dot net application.

I have created a Xi webservice and hosted it on a server.Now I want to consume this webservice in a dot net application. But while consuming it I get a binding error from the webservice.Does anyone has a solution fron this. Do I have to do some XI settings while creating web service.

have you used the WSDL created in XI - u can find it from http://<server>:<port>/wsnavigator/enterwsdl.html
Also use the link in soap:address location for your test purposes.
If proxy is involved in your network you will have to consider tht too and finally u sud use a XI user id to connect.

Consuming a WebService

Hi All,
Im following this help doc to build an application to consume a webservice.
http://help.sap.com/saphelp_nw04/helpdata/en/81/12703e5da3e946e10000000a114084/frameset.htm
What I want to understand is the following :
In point no 7. What configuration do I need to do with the logical port.
7. If necessary, configure the logical port.
In point no 8. What is SEI and how do I program my application using the SEI.
8. Program your application using the service endpoint interface (SEI).
What does the below mean? This is point no 8 continued.
When programming a client application, you receive a stub that implements the service endpoint interface through the implementation class of the service interfaces.
Transfer the Web Service Client API to the Java project class path that contains the client application. You can also add the Client API JAR file from the context menu of the Java Explorer in the Web Service perspective.

Hi
I have created a deployable proxy for this webservice. I have now created a EAR and have deployed this EAR on the JAVA WAS.
Then I have added the JAR file of this JAVA Proxy into my project using->Project->Properties->Add Jars.
The question is how do I use this proxy now.
Thanks
