ABAP server proxy as web service provider ??

Hi friends,
I am wondering that if is possible to expose an ABAP server proxy as a web service on NetWeaver ABAP. I tried that, but failed to call it.
I generated a ABAP server proxy by using the PI inbound interface. I can call the ABAP server proxy by PI. From SOAMANAGER of the beckend system, i saw that this just generated ABAP server proxy is a service. Then i curious if this generated ABAP server proxy can be exposed as the web service like other RFC function modules on the same beckend system. So i generated a ABAP client proxy by using the binding WSDL of the ABAP server proxy. But the testing of the generated ABAP client proxy failed.
So my question is if it is possible to expose an ABAP server proxy as a web service on NetWeaver ABAP?
The beckend system is SAP ERP 6.0 EHP4. The PI is 7.11.
Thanks!

In other words, is it possible to consume a server proxy by client proxy? If yes, how to consume it?

Client proxy consuming web service provider using logical port issue

Hi All,
I have a proxy client having a logical port (configured using NWDS) to consume a web service in the provider system.
In the logical port, I have given target address, and logical port name. While moving this client proxy NWDI dev track to Q and prod,
how do I change this target address to point to Q and prod respectively. In other words, even though I am using Visual admin to configure the destination url for the logical port, to point to Q and prod, its still referring to the dev environment provider service after moving the proxy client to Q and prod. What is the suggested approach to take care of this issue
Thx

Hi Michael,
I can only help from that point of view that I believe this question belongs to the forum
Service-Oriented Architecture (SOA) and SAP
Please try to raise this question there.

Visual Administrator and ABAP Client Proxy (external web service)

Hello,
I have generated client proxy in SE80. Is it possible to see it in Visual Administrator?
I need to make changes to some security setting and hoping to do it within Visual Administrator.
Thanks,
Alex

Hi,
I think that your are mixing things up.
A client proxy in SE80 is in the Abap stack.
Visual Administrator is used to configure the Java stack.
Don't forget that the Netweaver application server is mostly a marketing myth.
In real life there are a Netweaver Abap application server and a Netweaver Java application server.
These 2 application servers are sticked together with some "software glue"...

XI Server Proxy Or Enterprise Service

I need to call a BAPI in R/3 using XI. Possible Approaches:
1) Using RFC Adapter : Performance Inferior (I do not want to discuss this)
2) Using Server Proxy and calling the BAPI inside the method.
3) Exposing the BAPI as ES and consuming that using XI.
Now when we compare the approaches 2 & 3,
what are the basic differences in terms of security and performance.

Hi Sebin,
I guess you are getting confused.
I am exposing an RFC enabled function module as a web service in R/3. And to consume a web service I need a SOAP Adapter not RFC adapter.
So in both the cases, I mean server proxy and web service we are using xml messaging through SAP web app server. So, performance wise I do not think there will be any difference.
I am more concerned about the security and session handling.
Well, if we use Server Proxy, I know I can reap unlimited benefits like I can play with the data in R/3, or I can trace the message in R/3 at any point of time using SXMB_MONI.
But what are the security concerns involved in ES method.
And using ESA in this case does not add much because its not needed over here.
If we have any .Net or java application to integrate with, I would be more than happy to go for ES.
Well, in that case as well I would like to expose XI interface as web service rather than R/3 .

ABAP calling web service provided by AXIS -error

Hello expert,
I am calling web service provided by AXIS in ABAP but error occur when processing response part.
The web service is used to create material master in JAVA AXIS system.
After setting up the LP in soamanager then make a call, we got an error saying

For me it looks it is an issue in the response payload that ABAP proxy can not process it.
such as, the response payload NS prefix is soapenv, other than soap-env in request payload...
but i am not sure, whether this is the root cause.
Could you help me to find out what is going wrong here?

the response payload NS prefix is soapenv, other than soap-env in request payload
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" is equivalent to xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" . Namespace defined correctly.
I can also see that response is correct (assuming "S" denote success):
<CreateITEMReturn>S</CreateITEMReturn>
Also check type of WSDL style usually this error occurs if you are using RPC/Encoded style WSDL, modify wsdl for Document/Literal style (as RPC style WSDL not supported by ABAP proxy), see this discussion here: Cleint Proxy error

Problem with Consuming ABAP Server Proxy WSDL in InfoPath

Tried to design a InfoPath (MS Office 2003) form from a WSDL file of a web service generated from an ABAP Server Proxy in a NW2004s SP10 system. InfoPath rejected this WSDL with error InfoPath cannot use the selected Web service method for receiving data because the method does not provide valid XML data. Tried other WSDL files from other web services from ABAP Proxy with InfoPath, all got rejected.
Validated the WSDL file with XMLSPY, no error. Tried to import the WSDL into XI 3.0, no error. Also tried the WSDL in .NET C#, also worked fine. It seemed only InfoPath does not like this WSDL from ABAP Proxy.
Created a similar web service in XI 3.0 and InfoPath had no problem with its WSDL. Then I compared the two WSDL files. There are differences. After try and error on changing the differences, I have nailed down to the XML tag that caused the problem. Please see the extracted WSDL line attached at the end. In the XI 3.0 generated WSDL the wsdl:message and the wsdl:part have the same name. In the ABAP Proxy generated WSDL the wsdl:part has the name Parameters which is different from the wsdl:message. After I copied the wsdl:message name to the wsdl:part name, InfoPath accepted the WSDL file without any problem.
I know the fix but I like to find out the root cause. Is this a known issue? Did we miss some configuration setting thats causing this issue? Any help will be much appreciated.
WSDL from NW2004s SP10 ABAP Proxy
<wsdl:message name="RegionR3GetList_Req_MT">
    <wsdl:part name="Parameters" element="tns:RegionR3GetList_Req_MT"/>
</wsdl:message>
<wsdl:message name="RegionR3GetList_Resp_MT">

</wsdl:message>

Anne Tarnoruder has pointed out to me that her SDN article "Consuming SAP Enterprise Services in a Microsoft Office InfoPath Form" has described the the cause and workaround of this issue on page 9. I am extracting it below and mark this thread as answered. Thanks to Anne but not sure how I can award point to her.
Currently SAP supports only the Document style of WSDL, and not the Microsoft-specific RPC style, which causes a problem when consuming SAP services in the Microsoft environment. In this example, you need to apply a workaround that involves a minor correction of locally-stored WSDL files:
a. In the Project Explorer toolbar, click the Show all files icon and expand the Web reference folder.
b. For each Web reference in the project, perform the following steps:
c. Open the WSDL file, replace all instances of <wsdl:part name="parameters" with <wsdl:part name="parameter" (remove the s in parameters) and save the file.
d. Right-click the Reference.map file and choose Run Custom Tool to invoke a utility that generates code for XML Web services. This recreates the local proxy.

Limitation on data that can be fetched (ABAP RFC) via a Web Service?

Hi,
Is there any limit on the data that can be fetched via a Web Service (ABAP exposed as Web Service). I am trying to fetch PI monitoring data from ABAP Tables via a Web Service and there can be thousands of messages proceesed say in a day and what if user is provided the option of fetching messages for a specefic duration.
Please advise.

Hello my friend
If I understand your question correctly, there's an environment variable CPIC_MAX_CONV handles sessions between integration engine and adapter engine (ABAP and Java). By default, the value of this variable is 500, and you might want to increase it to 1000 at least, depends on system throughput. Recommended value from SAP for Production is 5000.
Hopefully it's helpful,

SOA - real time proxy to web service scenario

Hello Experts,
I am working on PI but really very much new to the SOA concept.
But i have to prepare document which explains about all steps that we need to follow (technicallly) for the SOA implementation.
We are going to implement one Proof of Concept for SOA before going for the real project.
Can someone please help me and tell me what all the things i need to do for Proxy to Web Service Scenario in PI.
I hope i have made myself clear about it.

Hi Gaurav,
Thanks for your advice.
I have one more question and i tried to explore SDN alot but didnt get satisfactory answer.
here is the situation:
My scenario is like :
.Net application = consumer
ECC = Provider
PI = broker
SR = Publish ES
I am using the Outside - In approach, where i am creating proxy structure in ESR and then creating/ Generating Proxy in ECC.
I am exposing my Inbound Interface on SR, so that the WSDL is available on SR.
Now the situation is, our consumer is asking data from us in different format.
I read on help.sap.com that via PI mapping it is possible.
But i am not understanding that consumer is using ECC WSDL to make a call, then even though mapping is there, how can they get response in their required format.
They are even providing us their WSDL. I am totally confused that in one interface how come two different WSDLs can work?
Or is there a way for this?
I am even ready to use the same structure for my ECC which is provided by consumer, but then i dont see any outcome using PI.
I also have question, that for standard service also, ECC Enterprise service structure is fixed which we expose, then using PI how can we provide consumers response in their desired way.
I know that m asking this question again and again, but still it is not getting clear to me... might be m not understanding that how it works in SOA.
If possible can you tell me the steps that i need to follow technically to develope this interface? so that i can get better understanding?
Thanks,
Hetal

HOW TO EXECUTE ABAP SERVER PROXY?

Hi,
I am working on a scenario in which message is passed from Integration Server to ABAP server proxy.
In case of client proxy we execute EXECUTE_SYNCHRONOUS methjod of proxy,but I am bit confused in case of server proxies.
How do we execute server proxy method?

Hi Similar to Client proxy, you will have the method EXECUTE_SYNCHRONOUS or EXECUTE_ASYNCHRONOUS for your server proxy. If your WebAS is based on 6.4 or above you can test the server proxy with a sample pay load very easily. In T-code sproxy, you will see a menu called proxy, Click on that and click test proxy, check the XML payload and you can enter the payload in the next screen and check your proxy..

Proxy to Web Service Communication doesn't work

Hi,
We configured the XI demo example Checking Flight Seat Availability (Proxy to Web Service Communication) (chapter 6.2) and everything works fine until we try to execute the szenario (chapter 6.2.3).
When we try to execute the szenario, we get an error displayed in the runtime Workbench. In the component Integration Server, we get a systemfailure with code ADAPTER.SOAP_EXCEPTION of category PARSING. The Adapter Engine also displays an error in the audit log:
SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: Authority check failed

Check out, that the URL of the WebService is correct:
"http://<YourServer>:<<b>ABAP_Port</b>>/sap/bc/srt/xip/sap/SXIDAL_FLIGHTSEATAVAIL_CHECK?sap-client=<<b>YourClient</b>>"
Change the default values if necessary.
Check in the client, if the role SAP_XI_APPL_SERV_USER (which should be applied to your user) is generated and has no errors.

What the mechanism of the Java Proxy for Web Services in WLS 8.1

Hi, all;
I try to find out how the java proxy of web service in weblogic server 8.1
works. Suppose I use the java Proxy of a WebSerice in a client application whatever
whithin or outside the application of the web service, does the proxy actually:
1. translate my java arguments objects in XML to create SOAP msg,
2. then send the msg across the network, and web service also response SOAP msg,
3. then proxy translate it into return value of the method call ?
If that is true , the Java Proxy seems very inefficient, right?
Can any body tell me how the proxy works ?
regards,
shannon

Hi Shannon,
The type of proxy I'm familiar with is at the http connection level and
associated with the networking properties in the JDK, See:
http://java.sun.com/j2se/1.4.2/docs/guide/net/properties.html
Your question may be related to JWS proxies, See:
http://edocs.bea.com/workshop/docs81/doc/en/workshop/guide/howdoi/howUseTheJavaProxyForAWebService.html
You may want to ask this question in the workshop newsgroup.
Hope this helps,

Database as Web Services Provider?

Hello!
Would you please forgive me my silly question but...
My customer has purchased and is using Oracle RDBMS 10g.
Now the customer wants the database to be accessible by web services clients.
The customer thinks that this can be done with already purchased RDBMS (without Oracle's Application Server). The customer cites Oracle: "Database as Web Services Provider: Database operations and data retrieval are executed through Web Services mechanisms" (http://www.oracle.com/technology/tech/webservices/database.html).
However, in my honest opinion the customer MUST install some web server. if the customer is especially insterested in Oracle's solutions, then it has to (additionally to already purchased RDBMS) buy either Oracle Application Server or WebLogic.
Who is right?
Sincerely Yours,
Michail

Michail,
For DB 10g, you are right - the solution is to use PL/SQL Web Services for which an OracleAS/OC4J server is essential.
For DB 11g, both you & your customer are right. In addition to the above like 10g, there is a new feature in 11g called Native XML DB Web Services within the DB which does not require any Web Server or AS. See http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
