Query: Authentication Error while consuming a web service

Hi All,
I've generted a WSDL file by using the following steps.
1.Created a RFC enabled ABAP pgm
2.Created a web service out of it (using webservice creation wizard - default virtual host. so my port is 8100)3.Released the web service (WSCONFIG)
4.Generated the WSDL file (WSADMIN + CTRL F1).
Then I wanted to consume it from a .Net program. But am getting authentication error in .Net.
Do I need to configure anything for Authentication (username and password) from R/3 side?..
How Do I pass the credential info from .Net?.
Should I take care of any setup other than what I've specified?.
Any Blogs or response would be appreciated.
Thanks,
Joe.

Usually like this:
WSReference1.WSPProxy proxy = new WSReference1.WSPProxy();
proxy.Credentials = new System.Net.NetworkCredentials("Username", "Password");
proxy.PreAuthenticate = true;
proxy.CallMethod();

hi,
for VBA and using the SOAPToolkit it would be something like:
Set my_client = New SoapClient30
my_client.MSSoapInit2 WSDL, str_WSML, c_SERVICE, c_PORT,
c_SERVICE_NAMESPACE
'using ProxyServer with <CURRENT_USER>
my_client.ConnectorProperty("ProxyServer") = "<CURRENT_USER>"
'Autodetect proxy settings if Internet Explorer is set to autodetect
'by setting EnableAutoProxy to True
my_client.ConnectorProperty("EnableAutoProxy") = True
'endpoint authentication
my_client.ConnectorProperty("AuthUser") = "SAP_USER"
my_client.ConnectorProperty("AuthPassword") = "SAP_PASSWORD"
I suppose it's similar in .NET.

Proxy Error while consuming backend web service

Hello,
I try to consume erp backend web services (generated on existing rfcs) with a web dynpro (java) application and get the following error:
Service call exception; nested exception is: com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (502) Proxy Error ( The ISA Server denied the specified Uniform Resource Locator (URL). ). The requested URL was:"http://anyExampleUrl"
The called backend service and the portal server reside in the network so no access through the ISA server is required. Consuming the same services by .NET applications works fine.
Do you have any hints?
Cheers, Dennis
Edited by: Dennis Isaak on Sep 23, 2009 2:18 PM

Hello there,
Check the same webservice is working fine with a SOAP UI, especially the request and response are fine. Then try with the application.

Consume a Web Service in ABAP

Hi,
We have a Web Service URL on PI. Run time of this Web Service in a Portal Server.
We need to access the Same URL from ECC using ABAP Programming?
Can any one tell me how we can call the same Web Service?
I need to pass few values to the web service using ABAP Code and I need to get back the result into some variables.
any code available for verify?
Thanks,
Sekhar.J

Hi,
Steps involved in Consuming a Web Service in ABAP.
1. You will need to create a Service Consumer Proxy in the ECC system.
The procedure for this is available in the documentation link [http://help.sap.com/saphelp_erp60_sp/helpdata/en/46/9743916d1115ece10000000a114a6b/frameset.htm] in the section Consuming a Web Service.. The URL access path of the WSDL can be used to generate the Service Consumer Proxy in ABAP.
2. Using transaction SOAMANAGER create the Logical Port for the Consumer Proxy created in Step 1.
3. Code the Consumer Proxy call in the ABAP program. Check section Consuming a Web Service --> Programming with Client and Server Proxies --> Sending a Message in the link specified above.
The Video link [Consuming Services in ABAP |https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/media/uuid/20eb3174-41ab-2a10-a383-907faf60eed3] will provide good conceptual knowledge, steps involved and Logical port maintenance..
In case you face any problems, shoot your queries.

Nitesh

Problems consuming a web service in ABAP

We wish to consume an external web service from ABAP but the provided WSDL file contains syntax not supported by SAP - namely "mixed content". A response from Roman Glushkov in forum thread [Call Sharepoint Web Service; seemed to offer a solution.
The WSDL file was edited as suggested by Roman and the Service Consumer proxy was successfully created from this edited version. However, in our SAP release (Basis release 700 support pack SAPKB70018) the "untyped mapping" indicator is not shown anywhere so we are unable to set that for those elements that were set edited in the WSDL.
The problem now is that when calling a method where the return parameters include one of these edited elements we get the error "SOAP:1,001 CX_ST_MATCH_TYPE:XSLT exception.System expected a value for the type g" presumably because SAP is trying to de-serialise the response rather than just return the data as an XML string.
Does anyone know how to get this "untyped mapping" indicator or can anyone suggest another way to solve this mixed content issue?
TIA
Gareth

Hi Tim
I've sort of got further in that I I can now call the web service method without error but structure returned is empty even though I know the SOAP response has data.
What I did was to go back to the WSDL and re-write the type declaration bit to fully describe the response message.
The appropriate portion of the original WSDL was;
 <s:element name="getActionListResponse">
 <s:complexType>
 <s:sequence>
 <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
 <s:complexType mixed="true">
 <s:sequence>
 <s:any />
 </s:sequence>
 </s:complexType>
 </s:element>
 </s:sequence>
 </s:complexType>
 </s:element>
The response SOAP message was;
<getActionListResponse xmlns="http://webcominc.com/">
 <getActionListResult>
 <RESULT xmlns="">
 <RESULT>
 OK
 </RESULT>
 <REASON />
 <ACTION>
 View
 </ACTION>
 <ACTION>
 Change Status
 </ACTION>
 </RESULT>
 </getActionListResult>
</getActionListResponse>
So I re-wrote the WSDL as follows;
<s:element name="getActionListResponse">
 <s:complexType>
 <s:sequence>
 <s:element minOccurs="0" maxOccurs="1" name="getActionListResult">
 <s:complexType>
 <s:sequence>
 <s:element minOccurs="0" maxOccurs="1" name="RESULT">
 <s:complexType>
 <s:sequence>
 <s:element name="RESULT" type="s:string" minOccurs="1" maxOccurs="1" />
 <s:element name="REASON" type="s:string" minOccurs="1" maxOccurs="1" />
 <s:element maxOccurs="unbounded" name="ACTION" type="s:string" minOccurs="0" />
 </s:sequence>
 </s:complexType>
 </s:element>
 </s:sequence>
 </s:complexType>
 </s:element>
 </s:sequence>
 </s:complexType>
</s:element>
Using this new version of the WSDL I recreated the ABAP Proxy but as I said this now returns an ABAP structure that is empty. I'm new to WSDL so its very probable that my attempt at defining the response message is incorrect or maybe it is something to do with the fact that the response message has two elements called RESULT - one being the child of the other?

Error while creating a web service

Hi all,
I am trying to create a webservice for doing SOAP to JDBC scenario. I created a WSDL file in Configuration. I am using NWDS for developing a web service using this WSDL file.
While creating a web service, I am getting 2 errors after creation of Custum controllers. The errors are as follows:
1. Request_SOAP2RFC_MI_SOAP2RFC_MI cannot be resolved or is not a type
2. WDMessageManager cannot be resolved or is not a type
I am making use of the following pdf file to create the web service.

Error while completing a web service

I have create a RFC, now to use that as a web service I have done the stpes for creating a web service as given in the link
sap technical link tutorial, web service create

what configuration required for this we have ECC6 system.

Edited by: zkarnalkar on Dec 3, 2010 11:13 AM

I guess that would depend on the error you're receiving - what is it? I've never seen a generation error for a service provider when following the few steps required, but you could debug the activation if the message isn't clear. Service consumer errors happen all the time and are generally related to WSDL file compatibility.

Error while creation of web service model in web dynpro

Hi,
I am getting following error "no services available or local server not accessible" while creation of web service model.
I have already created my web service nad deployed it. It was deployed successfully.
In the web service model creation wizard I am not able to see neither my web service nor any other standard service.

Are you using the deprecated Web Services model or the new adaptive web services model?
Take a look in this document: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b2bc0932-0d01-0010-6d8e-cff1b2f22bc7

Error when consuming a web service in CF 11

I am consuming a web service in ColdFusion what was written in .NET. Some methods of the web service work fine, but some we get the below error. We have identified the issue is the name of one of the properties in the web service appears to be the issue. The property name is ID. This is a very common property name so I would think someone has run across this before. It appears that maybe ID is a default property for Axis? I can dump the method that works and I see there is a getID() method with a return type of org.apache.axis.types.Id.
If we change the name of the property to something other than ID it works, but this will cause us to refactor a lot of code.
Here is the error I get when I try to call GetRoles method, which contains an ID property:
Cannot perform web service invocation GetRoles. The fault returned when invoking the web service operation is:
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException

I am running CF 11 Update 4.

I am not passing any parameters to the method (it has no parameters). On the ColdFusion side I do not use i1 anywhere. I will check with the .net developer on Monday to see if he is using it anywhere in his code. If he is he is using in consistently as the only methods that work from his service are those that do not have an ID property. All services with an ID property give me the same error message.

Error during creation of web service from abap rfc

Hi,
I'm creating a web service from abap rfc (SE37), but at the end of Creation Wizard I have this error:
"web service object already exist".
This is my first web service creation. Into WSADMIN there are not web services with the same name.
How can I solve this problem?
Thanks!

Hi,
What system/release/SP do you use ?
Beginning with Netweaver 7.0 SP14, you configure Web services with SOAMANAGER and you don't see them with WSADMIN...

Consuming a Web Service with ABAP in WAS 6.40 (SS3)

Hi Everyone,
     Has anyone successfully consumed a web service (based on an EJB) that is published to the J2EE engine of their WAS 6.40 server by creating a proxy from the ABAP layer?
     We are encountering the following problem: When executing method of the proxy to call the Web Service on the J2EE engine, the CX_AI_SYSTEM_FAULT exception is triggered with the message "Unallowed RFC-XML Tag (SOAP_EINVALDOC)".
     This same problem has occurred with multiple web services, even though the proxy generation seems to execute without a problem. Is there some system setting that could cause this? We have run the SOAP Runtime trace, but only receive the same basic information about the problem.
     If anyone has any thoughts at all, I'd be grateful to hear them.
     Thanks,
        --Greg

Hi,
We encountered problems when consuming a foreign WS. It seems to be that RPC style WSDL isn't supported by the WAS 6.4 WS proxy. An interesting reading on this is
