ABAP web service/ Virtual Interface

Hi all,
I'm trying to create a webservice for a ZRFC,when using the wizard in SE37>utilites>more utilities>create web service> from function module ,it's creating only the Webservice ,not prompting for a "virtual interface" .Same thing happens in se80,in create,under enterprise services node,i'm getting options only for web service and proxy object. Is there some thing missing.when excuting the webservice created from WSADMIN i'm getting 403 error ,page not found.
how do i create virtual interface ??.
we have version ECC 6.0,with software component SAP_BASIS 700 and java stack acitivated.How do i know what SAP Netweaver version we have ??.
any help !
Thanks
Bvan

Hi. As of Netweaver 2004s, the virtual interface piece has be absorbed into the creation of the web service definition, so there is no need to create it as well. When you are getting the 403, how are you trying to run this, using the Web Service Homepage? If so, you will need to configure what j2e engine that you want to use to use. You can do this in WSADMIN under the Administration settings. Check that this is set. YOu must know the URL of your j2e engine.

ABAP Web service - Virtual Interface Not Found

Hi,
I have created a ABAP web service based on RFC. I changed the authentication to "Basic username/password" from SOAMANAGER. Also tested the web service from WSNAVIGATOR (of different portal) using WSDL url. Web service successfully returned response.
Now, I have a AJAX client where I have hardcoded the request (from wsnavigator) and trying to call this web service in SAP BW web template (from HTML/JavaScript). But its not giving error as "Virtual Interface Not Found". Also, i get 500 error. But the end point of the web service if looked up from browser gives response. The SICF service is active and upon tests gives valid response.
Found couple of discussions regarding this:
http://wiki.sdn.sap.com/wiki/display/VC/VirtualInterfacenotfounderror
But i'm not finding the setting to activate virtual interface in SE80. ALso, we have created many such web services and they used to work fine prior to upgrade to Ehp1 SP05 (BI) but the newly created web service is not working.
Any inputs?
Abhijeet

Hi can you please let me know how you resolved this issue?

Publish Abap Web Service in ICF virtual host

Hello
We have configured our abap aplication server with two virtual host in SICF
one the default_host that listen in http 8080 port and other virtual host that
listen in http 8090 port.
We need define some ABAP web services that listen in default_host:8080 and other virtual host in virtualhost2:8090.
We define de web service with SE80 wizard and then create the configuration end point
with SOAMANAGER.
Our problem is that soamanager ever create the entrie of endpoint in sicf transaction, under default_host:8080 service tree not under virtualhost2 service tree. and so we can not call
the web service like http://virtualhost2:8090/sap/bc.... because don't exist, only exist
http://defaul_host:8080/sap/bc....
we try to copy the entry of the tree under virtualhost2 in the proper place of the tree,
but when call the webservice with soaui the system report the error:
No Web service configuration for this access path: ""
i can see that there are entries in the table SRT_CFG_SRV_ASGN that are related with this
problem, because assign the url of the endpoint of the ws to virtual host, but i don't
know how the system generate this entries.
someone know how call ABAP web service with icf virtual host?
thanks
regards
diego

Hi Trevor
For test purpose i can do it works.
The key point is create the proper entry in the table SRT_CFG_SRV_ASGN that refer to the correct VIRTUAL_HOST.
When you genreate the endpoint of the service with soamanager, the system generate an entrty in this table with the fiel VIRTUAL_HOST = 0, you can copy this entry and change only two fields.
VIRTUAL_HOST = <the number of your virtual host>
HASH --> you can calculate this field with the FM CALCULATE_HASH_FOR_CHAR, in the parameter DATA contatenate the content of the fiels VIRTUAL_HOST and URL (be careful with the upercase), this function module return you the hash.
(First you have to replicate the icf tree that soamanager create under your virtual host tree)
With this configuration i can call to my WS over the virtaual host, using soaui.
I hope this can be useful for you.

diego

ABAP Web Service with tables

Hello,
 
 
We need to build a web service with a predefined message in our ERP (ABAP), without PI or WebAS JAVA.
 
 
We thought it should be a simple task, because we had no problem with many other applications and systems when building the same service, but were not able to build it with SAP ABAP, probably as a consequence of our lack of knowledge on ABAP SOAP runtime.
 
 
We have an external asynchronous process that delivers information to many other systems using web services (information diffusion). Concecuently, the web service call's structure is determined by the caller, so we have to fulfill this structure if we want to receive the info.
 
 
The owner of the process defined a very simple service call, in which one kind of "record" can be repeated 1 to n times:
 
 
 
 
 
 
<reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
</reglasSuscripcion>
 
 
 
In order to receive this info, we have to implement an abap web service handler to accept this kind of call, the same way other applications/systems have already done.
 
 
We tried to build a RFC function call and create a web service with the wizard and it resulted in a web service with the following WSDL:
 
 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:soap:functions:mc-style">
 
 
 
 
 <reglasSuscripcion>
 
 <!Zero or more repetitions:>
 
 <item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 
 
 
<item>
 
 <nombre>?</nombre>
 
 <valor>?</valor>
 
 </item>
 
 </reglasSuscripcion>
 
 
 
 
We found two main problems:
 
 
1.- When "wrapping" the RFC as a WS with the wizard, for a table datatype it automatically includes the <item></item> tag, so we break the predefined calling rules.
 
 
2.- The namespace is fixed by the wizard, and we would like to use a common namespace for all the "susbscribers", logically, the namespace fixed by the information diffusion service.
 
 
We also tried to find info on the outside-in approach for building a web service from the WSDL, but all the info we found required the ESR and we have no PI, just the ERP.
 
 
Any ideas on how to proceed?
 
 
Thanks in advance,
 
 
Joseba M. Iturbe

#2. I've recently had to "zap" some namespaces in an ECC5 system because the calling (TIBCO) system didn't appreciate the default SAP "urn" default - something to do with multiple colons in the address. There were, I think, just three table this affected, all VEP* ones. I think I should have been able to change these via the virtual interface in SE80 except that the ECC5 code was a bit "light" in this respect, so you may be able to do this now in SOAMANAGER in ECC6 (btw, I also had to re-save the WS definition within WSCONFIG and re-activate the virtual interfaces after this "zap" to generated the associated handler class again).
#1. Given your "name / value" pairs represent a complex type, then it might be better practice to have them as "item" which is probably why SAP proposes it this way... what does your custom function module parameter list look like?

ABAP Web Services problem

Hello everybody. I'm trying to publish a Web Service created in ABAP (R/3 6.0 release) in my JAVA WAS trial version 2004s. I'm following the ABAP Web Services tutorials (6.40) but when I try to create the Virtual Interface, in the SE80 from the context menu of Enterprise Services, there's no Virtual Interface option. Can anyone tell me how do I set up a Virtual Interface in 6.0 release of R/3 or how can I make it available in the context menu of SE80? Thanks in advance.

Better try the methods get_asList... for tables.

ABAP web services

HIII..
I want to know about a ABAP web service . How this can be created????
Thanks in advance.
Regards
Mayank Saxena

Hi,
Web Services
Business processes consist of individual process steps that can vary in how extensive they are. One or more functions are then assigned to these steps; an executing software component is then assigned to each function. Clearly, the heterogeneous nature of system landscapes in enterprises makes it impossible to implement all the necessary functions associated with a complete process using the same technology on the same component. A modern software infrastructure must be in the position to integrate functions, implemented on widely differing software components, in one effective complete process. Until now, the combination of different applications has largely been based on manually declared interfaces, message formats, and agreements between business partners.
Web services simplify this process. They are based on open, generally accepted standards. They enable you to combine functions in a single process, even if they are implemented in widely differing software components. Web services are standalone, executable entities that can be published, searched for, and called, across a network.
Introduction
The SAP Web Application Server implements the following basic Web services standards: eXtensible Markup Language (XML); Simple Object Access Protocol (SOAP); Web Service Definition Language (WSDL); and Universal Description, Discovery, and Integration (UDDI).
In the documentation that follows, we assume that the reader is familiar with Web service standards and techniques. You will find a general introduction to the Web Services topic under Sun Microsystems, in the pages of W3C, and in the general explanations for standardization organization OASIS under the topic UDDI.
Integration
ABAP and Java Web Services
Enterprises can extend their solutions by using Java or ABAP Web services, or both. If your priority in programming an application is the selection of data, the integration of an ABAP Web Service could be appropriate. Conversely, if you are implementing processes that involve different business partners and systems, it may be beneficial to program in Java and integrate Java Web Services.
The Web Service Framework consists of:
·        The development environment for the ABAP Engine
·        The development environment for the J2EE Engine
·        Tools that support UDDI registration
·        A distributed, interoperable SOAP runtime (ABAP and J2EE Engine)
Processing of SOAP requests using the Internet Communication Framework
Web Services and the SAP Exchange Infrastructure
The SAP Exchange Infrastructure is a key area in SAP NetWeaver. The Exchange Infrastructure provides an open, process-oriented integration infrastructure for the unhindered flow of information and for XML-based message exchanges. Systems integrated using SAP XI exchange messages over the Integration Server.
The programming model for XI ABAP proxies and Web services has been unified. The advantage of this is that both technologies can be implemented so that they complement one another. Messages can be sent and received either using the XI runtime or the Web service runtime.
Additional proxy runtime services can be controlled using protocols that you request using a proxy method. The features you have available depend on whether you are using the Web Service Framework or the Exchange Infrastructure for communication.
Features
The ABAP Workbench offers an environment where you can publish, search for, and call Web services. It enables the SAP Web Application Server to act both as a server and client for Web services.
The Web service infrastructure enables developers to:
·    Publish independent function that were implemented as RFC-enabled function modules, function groups, BAPIs, or XI message interfaces. This includes functions available as part of mySAP.com solutions, or functions developed by customers or partners. The Web service can be used across the entire Internet using standard protocols and can easily be added to any development environment. (See also Creating a Web Service).
·    Consume Web services, regardless of where they are stored or how they are implemented. Business processes can be implemented across several systems, either within an enterprise or across several enterprises. (See also Consuming Web Services.)
The following triangle shows the basic architecture of the Web Service Framework:
Service Provider
After the functions have been implemented, a Web service interface must be created that provides a representation of the Web service for the user. This interface offers an abstraction layer and thus independence from the specific implementation used. Based on this interface, the Web service is configured and can be called at runtime. Publishing Web services in a UDDI Registry is supported by the UDDI client functions in the SAP Web AS.
Service Directory
You can store Web service definitions and released Web Services in a UDDI Registry. WSDL documents provide the basis of the Web service client, which can then be searched for in the UDDI using either a browser or the standard UDDI APIs. Web services can be published and searched for in all registries that conform to the standard. SAP also offers a public UDDI Business Registry under uddi.sap.com.
Service Requestor
The SAP Web AS allows you to integrate Web services. It can generate Web service clients from WSDL files.
Standardization and Extensibility
Web services and Web service standards develop quickly; new standards are being presented continually at standardization committees. However, these extended standards such as security standards or additional protocols can easily be integrated in the Web Service Framework using SAP.

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
Best Regards

SSO and ABAP Web Services

I am opening this thread on behalf of my colleague Bala regarding SSO and ABAP Web Services.
We have gone through single sign on options and found several options are available within 5.0.
We would like to know the options available for SAP ABAP web services access from a Non-SAP system with user authorization but without Portal/ITS installation.
Also I would like to avoid any hard coding of user id in Non-SAP system .
Could you provide any information.
Thanks,
Bala

We have gone through single sign on options and found several options are available within 5.0.
Tell me what are the several options and what is your Non-SAP system?
without Portal/ITS installation.
ITS is now an integral part of ECC 5.0 system. So would not need a seperate installation, unlike earlier versions.

I have WAS 6.4 with ABAP STACK and NetWeaver '04. I created an ABAP web service, it was deployed successfully, but while running it I am getting an error that "Settings for J2EE do not exist".
Do I need to configure anything to rectify this error....?
Plz suggest me.

Call a ABAP Web Service externally

Hi Experts,
I have a question on ABAP Web Service:
is it possible for Company A to call a ABAP Web Service from Company B externally? If yes, how would the it be done? How would the authority be controled? The calling of a Web Service externally, is there anything to do with XI?
Looking forward to your help!
Thanks!
Hua

Yes it is possible. It is possible with or without XI (based upon the WebAS release you are on). WebAS 640 has extensive functionality over WebAS620. Authority can be controlled in several different ways (HTTP authentication -Basic or HTTPS, Client Certificates, WebService Profiles).
There is lots of good on-line help and a sub-area of Web AS on SDN dedicated to Web Services where you can find many of your answers.
You can also check out my weblogs. I have written on the subject of ABAP WebServices without XI several times. There are real world examples from my compnay.
One thing that I might add is that that if you are going to call outside of your company's network you will likely have to configure the client proxy settings in transaction SICF.

Consuming ABAP Web Service in Non SAP system

Hi
I have created an ABAP web service form the RFC and configured it in the SOAMANAGER. I have tested it in Web Service Navigator using the URL and it is working fine.
Now I am trying to access it from the Non SAP system using Java Code. I am able to access the WSDL using the URL from the step 1 but not able to receive any output when providing inputs.
So I am not sure if I am missing any configuration on the Provider System (SAP) or on the Consumer system (Non SAP) to access the web service. As far I have not configured anything on the consumer system. Please let me know how to consume the web service in the Non SAP system.
Thank you,
Rohit

not necessarily an answer to your question, but i find that when creating SAP web services, before we create the code for consuming them, I always test them with the SOAPUI package. with this test suite you can import the WSDL, and run individual tests, seeing the input, output, exceptions, etc. This is a good way to check the connection, the flow and the service logic, before writing any code. This will also let you know whether it is a WS issue, or an issue with your code.
just a thought, from someone who has been there...
http://www.soapui.org is where you can find the SOAPUI. It helped me out a lot.

Web Service Model for ABAP Web Service

Hi,
I have developed ABAP web service and called it using web service model in WD. The WS is working from WSNavigator. While calling it from WD, im getting the following exception:
Service call exception; nested exception is:
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (502) Proxy Error ( No data record is available ).
Is some setting required in R/3 where WS is created or on WAS where the WDAppl is deployed?
Regards,
Smruti

Hi Smruti,
Please try the following:
Go to Web Service model
Logical Port
Uncheck "Use HTTP Proxy" settings..
Also make sure the WAS has entry of R/3 in hosts files..

ABAP Web Service client proxy - generation problems

Hi!
I tried to create an ABAP web service client proxy for many different web services -
for instance some of that listed at <a href="http://www.xmethods.net/">http://www.xmethods.net/</a> .
Almost on 99% of the WSDLs the client proxy generation failed.
For istance "<extension> not supported", or "<message...> must have at least one part",... .
Could anybody tell me what restrictions are to web services you can create a
ABAP client proxy for ?
In the SAP Web AS Java Stack there is no problem at all to generate a
client proxy for almost all of the xmethod-WebServices !
Is the ABAP Web Service proxy generation for production use ?

How to debug ABAP Web services from Microsoft Visual Studio

When developing .NET based Web services clients using Visual Studio that call Web services in SAP NetWeaver .NET developers would like to be able to debug inside SAP. In my blog <a href="/people/andre.fischer/blog/2007/02/07/how-to-debug-abap-web-services-from-microsoft-visual-studio to debug ABAP Web services from Microsoft Visual Studio</a> I would like to point .NET developers to the fact that SAP NetWeaver offers the option of external debugging to perform this task. Though the steps that have to be performed are described in the SAP Online Help I am sure that this option is not well known amongst the .NET developer community.

Hello WilliamIV,
>>How can I "configure" Visual Studio debugger to allow validation to work?
Since I do not have a VS2012 environment, according to your provided link, I created a test demo with VS2013, however, both ways catch the validation error:
If possible, you could have a try with VS2013 to see if it works or run the example on other machine with VS2012 to see if this is caused by the VS environment, in my side, I do not change any configuration, all are default.
If I misunderstood this issue, please feel free to let me know.

Transport of ABAP web service

Hi,
We can see that the end point /binding of an ABAP web service is not transported.
Would you have a solution. We cant create a new binding everytime, because the client would not know how to lookup for the web service without a pattern. The second thing is transport is not a one time activity, it happens with every modification.
and we cant be creating a binding every other time.
Third what about production. Production should not be used for making changes.
Do let me know the answers to these questions.
Thanks,
Harish

Hello All,
We are facing a problem with the webservice transport. The application consuming the service is working fine in CE 7.2 DEV. But after transport to CE 7.2 Quality, there is one service which is resulting in this error.
Invalid Response content type. Server returned code (500) with message <Internal Server Error> and content type <text/html; charset=utf-8>. Http proxy info: none
[EXCEPTION]
com.sap.engine.services.webservices.espbase.client.bindings.exceptions.TransportBindingException: Invalid Response content type. Server returned code (500) with message <Internal Server Error> and content type <text/html; charset=utf-8>. Http proxy info: none
For the rest of the services the content type remains as test/xml, only for this service it gets modified to text/html. This is the only difference we could identify. Any help on this is much appreciated.
