How to call a webservice proxy from BPM application?

Hi All,
Consider a case where I want to use external webservice in my BPM application. What is the best approach to achieve this.
1) What if I create a web service proxy and wants to use in the BPM app. How can I use this?
2) Which component do I need to use "Web Service" component or "Third Party Adapter" component from the component pallette?
3) If I use directly the wsdl in the "Web Service" component will it cause any issues in the future.
I searched in the net and the docs, but it didnt find the proper solutions for this.
Please provide your comments on this.
Thanks.

First of all a java proxy would not help much here - there is no use for that in SOA suite especially when it comes to using the JCA adapters. Instead reference the WSDL directly in SOA suite but there is a caveat - see my response below
1) What if I create a web service proxy and wants to use in the BPM app. How can I use this?
Dont create a WS proxy. Instead reference the WSDL and call it using a Service Task from the BPM process
2) Which component do I need to use "Web Service" component or "Third Party Adapter" component from the component pallette?
Use the WSDL directly and select "Web Service" from the component palette
3) If I use directly the wsdl in the "Web Service" component will it cause any issues in the future.
Yes there are lots of issues referencing a WSDL directly. Instead upload the WSDL reference to SOA-MDS and then use the oramds:// reference to the WSDL. This will ensure the composite does not break when the WSDL is not available. JDeveloper also goes into a tizzy when the WSDL is not up.
thanks,
Vikram

How to call a web Service from Oracle Applications?

Hi friends,
I've posted this question on OA Framework forum , but may be it's more appropiated put it here. Sorry for do it again:
It's about how to call a web service from a Form or a .sql (via Request) in Oracle Applications:
Could you please explain here the detailed steps (with code example if it's possible) to invoke a webservice from Oracle Applications?.. how did yo do it...?
I've read differents posts here and the 33097.1 metalink note (by the way, the first recommended link in this note is broken...), but there are lots of theorical concepts and no real examples to see how/from where invoke the WS
I'll have to call one webservice (I suppose the customer will give me the interface implementation)...but I've never did it with Applications so that's why I ask you for all the detailed steps...
I work with Forms 6i, Apps 11.5.10.2 and DB 9.2.0.7.
Thanks a lot.
Jose.

Hello Jose,
I did using java program to call BPEL web services in 11.5.10.
I pasted below the metalink note for your reference (Note:250964.1)
The idea is first write a java program to call the webservice (in my case it is calling an BPEL web service, so this may not help directly), test it.
Then port the java program as specified in the note, so that you could call your web service through concurrent manager scheduler.
Is this ok?
Thanks
Arun.

How to call/show page(s) from different application

Hi All,
I'm working on couple of applications and some reports (about 30) are used in all applications. I need your advice on doing this efficiently.
Is it possible to
1) Create a separate application with all the reports.
2) Create a blank page with lists linking to all those reports on the same tab
Now, is it possible to call that page in a "reports" tab of each application without prompting for login and still have rest of the tabs visible while the user is using the reports?
Thanks in advance,
Asha

Asha,
you can create links to call pages from other applications without any problem, just take a look at the structure of APEX URL over here: http://www.oracle-and-apex.com/apex-url-format/
To avoid re-logins you could either disable security on your application (not recommended) or create a custom authentication scheme which takes logged in users from other applications as granted.
brgds,
Peter

** Is it possible to call a Proxy from BPM ?

Hi friends,
Our requirment is to take the thru JDBC (data required to create Sales Order) and call the Standarad BAPI 'BAPI_SALESORDER_CREATEFROMDAT2'. Since BAPI is not able to handle multiple sales order, we want to use this BAPI in inbound proxy and want to call from BPM.
Since we want to call continuous BAPIs one by one, (Sales Order, Delivery, Invoice) we want to design this scenario using BPM.
I understand that we are not able to create proxy for Abstract Interfaces. BPM only understands abstract interface. In this case, how do we call proxy from BPM? Is there any other possibility?
Kindly reply friends.
Kind Regards,
Jegatheeswaran P.

hey,
yeah its possible..

Hi Mohan,
You need an account for the ES Workplace. I'm afraid this is not free, e.g. check [SAP NetWeaver, Composition Subscription|https://www.sdn.sap.com/irj/sdn/subscriptions/composition].
But I thought you wanted to play with a WSDL [you already had at hand|Sample code to access BAPI Web services from JAVA required;?

How to call a SAP service from adobe flex

Hi experts,
I need to call a webservice create from SAP BAPI my URL is: http://xxxxxxxxx:8000/sap/bc/srt/wsdl/bndg_DD90E166ACE1B1F18AD8001B789FF0AD/wsdl11/allinone/ws_policy/document?sap-client=200, with this URL I can test the webservice from WsNavigator.
The operation is ZimrfcVerifOtUbica and the input structure is:
ZimrfcVerifOtUbica
> PiNumeroAlmacen (input parameter)
> PiOTransporte (input parameter)
The output structure is:
ZimrfcVerifOtUbicaResponse
>PoMessage (output parameter)
I've created a view with two inputfield (one to PiNumeroAlmacen, one to PiOTransporte), one button and one label (to put the result value).
but I don't know how to call the WS, I tried with this code:
<mx:WebService id="ZCCONVERTERService"
     wsdl="http://xxxxxxxxx:8000/sap/bc/srt/wsdl/bndg_DD90E166ACE1B1F18AD8001B789FF0AD/wsdl11/allinone/ws_policy/document?sap-client=200;" useProxy="false" >
          <mx:operation name="ZimrfcVerifOtUbica" resultFormat="e4x">
               <mx:request >
                    <PiNumeroAlmacen>AGR</PiNumeroAlmacen>
                    <PiOTransporte>01000</PiOTransporte>
               </mx:request>
          </mx:operation >
     </mx:WebService>
and I get this error: [RPC Fault faultString="Could not load WSDL" faultCode="Server.NoServicesInWSDL" faultDetail="No <wsdl:service> elements found in WSDL at ."].
I tried with actionscript and runtime library but I get this error: java.lang.Exception: Unsupported element in WSDL file: UnknownExtensibilityElement
I tried put in Data--> Import Web Service and I put the URL and I get Unable to load the WSDL. Specify another URI.
Other thing is for this webservice I've created a logic destination, and this webservice is used in a webdynpro aplication and works correctly. But now I need to use the same webservice in flex.
Could you help me to call to this webservice?
Thanks in advance.
Jose

I have could do it, but now I'm trying to do the same with a SAP standard service.
Any idea?

How to call a web service from forms 9i

Hello all, I was trying to run the example on this website that shows how to call a webservice from forms, and I recieved an error. I am at the last step, where it tells me to create a button and add a when button pressed trigger. Here is the code I am using from the example:
DECLARE
jo ora_java.jobject;
rv ora_java.jobject;
ex ora_java.jobject;
BEGIN
jo := CurrencyExchangeServiceStub.new;
--This will get the exchange rate from US Dollars to UK Sterling.
rv := CurrencyExchangeServiceStub.getRate(jo,'USA','UK');
message (float_.floatValue(rv));
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
It gives me an error on"Exception_.tostring" component must be declared. Does anyone have any suggestions? I am trying to figure out how to call an external WS from a form. Thanks.

How to call a webservice (e.g. MII)?

I am looking for information how to call a webservice (e.g. a transaction in SAP MII) in SAP ME. For example, I have to call a webservice when the user clicks the "Start" button in a POD. Is this something I can only achieve by implementing my own activity hook? Is there a documentation about this topic?

Hello,
I try to do the same, calling a MII Webservice from a collaboration plug-in...
Based on my WebDynpro experience, I was expecting to have to reproduce almost the same code, so in the transporter, I write this code :
          MyWebService ws = new MyWebService();
          InputParams inputParams = new InputParams();
          XacuteRequest xacuteRequest = new XacuteRequest();
          // inputParams.setIFEQUIPMENT(inputInformation.getString("RESOURCE",""));
          inputParams.setIFREPORTEDBY(inputInformation.getString("USER",
                    "Unknown"));
          xacuteRequest.setLoginName(Constants.LOGIN);
          xacuteRequest.setLoginPassword(Constants.PWD);
          xacuteRequest.setInputParams(inputParams);
          try {
               XacuteResponse xacuteResponse = new XacuteResponse();
               xacuteResponse = ws.getMyWebServicePort()
                         .xacute(xacuteRequest);
          } catch (Exception e) {
               returnData.put("EXCEPTION", e.toString());
               returnData.put("SUCCESS", "false");
               returnData.put("ERROR_MESSAGE", e.getMessage());
But when executing, I got the error message "can not authentificate the user" (on the local Netweaver, it doesn't reach the MII platform)
Any idea ? Who can give me a complete example of calling an MII web service ?
Thanks
Olivier

Client Proxy : How to Call Outbound Generated Proxy in ABAP report ?

Dear SDNrs.
I have already created a Scenario for Client/ Outbound Proxy in XI .
I have already Generated Client/ Outbound Proxy in ECC .
Now Question is How to call this generated Proxy in report ?
Please Guide ..... I dont have any idea ...
1. before calling any proxy in report what information needs to collect from generated Proxy ?
2. How to call this generated Proxy in report ?
Regards
Prabhat Sharma.

Hi Prabhat
You have to use your knowledge about ABAP OO for this.
It's simple. You created your Proxy Object throught SPROXY transaction, right? Now, you have to instance your class (information avaliable in SPROXY-> Proxy Objetc -> Class Name) and to use the method displayed there.
Follow an example:
DATA: wa_backfeed      TYPE zibrsapglbackfeed_sapgl,
           wa_output            TYPE zibrsapglrequest,
           lo_clientproxy       TYPE REF TO zibrco_sapgl_out,
           lo_sys_exception TYPE REF TO cx_ai_system_fault.
TRY.
      CREATE OBJECT lo_clientproxy.
      CALL METHOD lo_clientproxy->sapgl_out
        EXPORTING
          output = wa_output.
    CATCH cx_ai_system_fault INTO lo_sys_exception.
               lo_sys_exception->if_message~get_text( ).
ENDTRY.
