Calling a web service with URL to Insert into DB Web service

Does any one have an idea how I can call a web service using a URL to insert records into an Oracle DB table.
Something like this :
http://apex.oracle.com/pls/apex/SCHEMA/URI/HANDLER/PARAMETERS
I need to call it outside of Oracle Apex.
Regards,
OLU

Hi Swapna,
from your screenshot it seems that you actually try to call the service in your Data Source Expression field. You should set path to the WSDL file here actually - this could be either URL to SAP or to filesystem, as Anton suggested (this could be faster). Have you created endpoint binding for your service in transaction SOAMANAGER? If yes, then simply download the corresponding WSDL with binding or copy the URL which leads to it. But also test whether you are able to retrieve the WSDL without logging into SAP (close all browser windows and then open a new one otherwise session ID from other browser windows can be reused).
If you have to give username and password, then setup anonymous alias in transaction SICF, for example.
Pleas, check my previous post on the same subject here: Re: BCM7 IVR : SOAP request for client identification in CRM .
Maybe it could help.

Issue with calling external web service with authentication details ...

Hi,
     I am facing a deployment issue with Oracle ESB. I am trying to call an external Web Service with authentication from ESB SOAP Service. It is working fine with my local ESB version 10.1.3.3.0 Build PCBPEL_10.1.3.3.0_GENERIC_070615.0525; however it is getting an error at our development ESB version 10.1.3.3.1 Build PCBPEL_10.1.3.3.1_GENERIC_RELEASE.

Calling a Web Service with a File Binding Component

Is it possible to call a web service (inside a bpel process) using a File Binding Component?
It seems that the File Binding Component should read an XML representing the input - is this possible? I found something about an "input-file-type" for the message, is this the way?
Thank you,
Marcos Ackel

Hi
" have done one small application with Bpel which read messages from port and write to file in xml format using file binding........"
By your description of this application, I'm sure it is using the HTTP BC to read incomming messages, and then the File BC to write them to a file. I think the original question is whether the File BC can call a web service which is very different.
Either way, when calling Web services, the recommended BC is the HTTP BC.
Cheers

Call ABAP Web Service with Java code only

Hi all,
First of all, I am writing script in Adobe form but am not using the one in SAP.
I am trying to call the web service and process the result with script open (i.e. no dataconnection created), because I am trying to do that in a dialog.
I can call a non-SAP web service without problem, but I am not able to call a simple web service with only a single string input, anyone have any example?
Here is the SOAP for input:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:sap-com:document:sap:rfc:functions">
   <soapenv:Header/>
   <soapenv:Body>
      <urn:Z_RFC_GET_STAFF_BANK_INFO>
         <A_STAFF_ID>0123456</A_STAFF_ID>
      </urn:Z_RFC_GET_STAFF_BANK_INFO>
   </soapenv:Body>
</soapenv:Envelope>
Here is my code to call:
     var cURL = "http://some-host-name:port/sap/bc/srt/wsdl/bndg_DEDB492BB032E7F1B09F001CC4FBCEC9/wsdl11/allinone/ws_policy/document?sap-client=300";
     var response = SOAP.request(
          cURL: cURL,
          oRequest: {
               "urn:sap-com:document:sap:rfc:functions:Z_RFC_GET_STAFF_BANK_INFO": {
                    A_STAFF_ID: "0123456"

Hello I have the same problem, were you able to execute the WS through the JS code now?
I would like to call an ABAP WS using JavaScript to return complex structures that I would like to manage directly with JS.
I tried with this code and I get the error "RaiseError: Acrobat Raise." when the request is executed:
var WSUrl = "http://<server>:<port>/sap/bc/srt/wsdl/bndg_4D15C75529330AF1E10000000A150429/wsdl11/allinone/ws_policy/document?sap-client=500";
var VendorNumber = xfa.form.DATA.DATAFLOW.SF_HEADER.VENDOR_NUMBER.rawValue;
try {
// Create request structure, read Input out of text field
var request = {
          "urn:sap-com:document:sap:soap:functions:mc-style:ZWsTest" : {ILifnr: VendorNumber}
SOAP.wireDump = true;
// Call web service using SOAP object
var response = SOAP.request ({
        cURL: WSUrl,
        oRequest: request
//        cAction: "urn:sap-com:document:sap:soap:functions:mc-style"
} catch (e) {
    xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
with this other code I get the error "SOAPError: CX_ST_MATCH_ELEMENT:XSLT exception.System expected element 'ILifnr'":
try {
    var myProxy = SOAP.connect(WSUrl);
    var result = myProxy.ZWsTest( { ILifnr: VendorNumber } );
    xfa.form.DATA.DATAFLOW.SF_HEADER.E_DESCRIPTION.rawValue = result;
// Display the response in the console:
   console.println("Result is " + result);
} catch (e) {
    xfa.host.messageBox(e.toString()); //pop-up "TypeError:service.CelsiusToFahrenheit is not a funciton"
in the second option, if I make the field ILifnr optional the call is succesfully performed but the parameter is not passed to the WS. So the call is working.
Using stand-alone LiveCycle designer 8.1 and Adobe Reader 8
Any suggestions?
Many thanks,
G.

UWL connector: problems with calling a web service with a SAPLOGONTICKET

Hi,
I want to implement a uwl connector that calls a web service to retrieve the uwl items data with a SAPLOGONTICKET. If I refresh the UWL I get the following error.
An error occured while reading data from the destination sap.com/com.xxxx.connector.RequestLeaveDP/com.xxxx.connector.RequestLeave/Config1Port_Document. The error was: com.sap.security.core.client.ws.SSO2Exception No SAP Logon Ticket was found for the user. Please ensure the user authenticated using HTTP/HTTPS and the JAAS login stack has been configured correctly. As an alternative, consider changing the authentication type to Assertion Ticket. .
If I call the Web Service in an iView I don't get this error. Maybe the UWL calls the web service not with the current authenticated user.
I tried the following code, to get the current SSO2 Ticket from the current user. It looks like, that is the current user, but the web service will not accept this. (testing purpose)
com.sap.security.api.IUser currentUser = com.sap.security.api.UMFactory.getAuthenticator().getLoggedInUser();
String logonTicketUwlUser = (String) context.getUser().getTransientAttribute("com.sap.security.core.usermanagement", "MYSAPSSO2_STRING");
String logonTicketCurrentUser = (String) currentUser.getTransientAttribute("com.sap.security.core.usermanagement", "MYSAPSSO2_STRING");
InitialContext contextWebService = new InitialContext();
RequestLeaveWebService requestLeaveWebService = (RequestLeaveWebService) contextWebService.lookup(wsClient);
RequestLeaveWebServiceViDocument webServiceEndPoint = requestLeaveWebService.getLogicalPort("Config1Port_Document");
UWLHolidayItem holidayItem = webServiceEndPoint.getHolidayItem("");
Any ideas?

Best Practice for WSDL Generate Proxy Class for Web Service with Two Versions

Dear All
Thank you in advance for you help.
I would like to generate proxy classes for same function but with two versions.
Old version web service (v23.2) is used for stable modules in a project which is not going to modify.
However, enhancement is added in new version web service (v24) and is going to use in any future modules.
For example,
wsdl.exe -o="TestProxy.cs" -l:CS -n:Test -sharetypes https://community.workday.com/custom/developer/API/Notification/v23.2/Notification.wsdl https://community.workday.com/custom/developer/API/Notification/v24.0/Notification.wsdl
It generates similar classes with an '1' added at the end of the class name.
ublic partial class Event_TargetObjectType {
private Event_TargetObjectIDType[] idField;
public partial class Event_TargetObjectType1 {
private Event_TargetObjectIDType1[] idField; ...}
Since the function inside some class is the same, is it possible for WSDL.exe to generate proxy classes automatically that if the class is the same, then generate one class only (sameFunction()) but if it detects the class is different, then add '1'
to the end of class name (differentFunction() and differentFunction1())
i.e.
public class sameFunction()
public class differentFunction()
private int a;}
public class differentFunction1()
{ private int b;
Best Regards
mintssoul

Hi mintssoul,
As per this case, I have shared corresponding details below :
1.As far as I know, WCF doesn’t support method overloading directly
2.Because WSDL doesn’t support method overloading (not OOPs).
3.WCF generates WSDL which specifies the location of the service and the operation or methods the service exposes.
4.WCF use Document/Literal WSDL Style : Microsoft proposed this standard where the soap body element will contain the web method name.
5.By default all the WCF services conform to the document literal standard where the soap body should include the method name.
6.but you can differ the method in the same manually by using Name attribute like below
For example:
    [OperationContract(Name="Integers")]
    int Display(int a,int b)
    [OperationContract(Name="Doubles")]
double Display(double a,double b)
7. Or I suggest you that can use svcutil to map multiple namespaces for generating wcf service proxies .
    for more information about this, refer here :
http://stackoverflow.com/questions/1103686/use-svcutil-to-map-multiple-namespaces-for-generating-wcf-service-proxies

Calling j2ee web service with portal user

Hello,
I created web service using Nwds Ejb.
I want to run this web service from sap portal iview and to receive the same user Id that logon to the portal , on the web service side.
In the j2ee Ejb code I am using :
try{
String username = myContext.getCallerPrincipal().getName();
IUser user =
UMFactory.getUserFactory().getUserByUniqueName(username);
return user.getUniqueName;
} catch(UMException e) {
return e.getMessage();
But the result is always Guest ?
even if I selected use sap authentication on the wsdl descriptor.
Need some help solving this issue?

Calling KM Web-Service with SSO from EJB

Hello Community-Folks,
i have developed an EJB which already uses KM-Webservices to interact from my NW 7.1 CE App-Server (SP5) with out KM on an NW 7.0 (where our Portal also runs on).
For using the KM-WebService i have to authenticate to the KM. At the moment i use the following code to connect and authenticate
rf = new RepositoryFrameworkWS(wsdlUrl, new QName(this.Default_QNSUri,this.Default_QNSLPart));
vi = rf.getConfig1Port_Document();
((BindingProvider)vi).getRequestContext().put(BindingProvider.USERNAME_PROPERTY , username);
((BindingProvider)vi).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY , password);
But this EJB itself is called from another bean of my application and from Java Web-Dynpro Apps on my NW 7.1 CE-Server. The user normally authenticate to my applcation and i now want to use that logged in user to authenticate to the KM also. In my example above i have to know user and password for HTTP-Basic-Authentication.
But what do i have to do using a logon-Ticket instead?
Ironically my Web-Dynpros are called from a Portal, and the user is athenticated to my Web-Dynpro-App using sso from the portal. In this WD-App i know want to authenticate against the KM (which resides on the portal where the user came from).
Any hints are warmly welcome,
regards
Matthias

I am calling a web service (with header information) from BPEL. In the Invoke activity, i created a header variable to pass the header information.
But, when i test the BPEL service, invoke activity fails because the header information is not being passed.

Call a Web Service from within an e-Sourcing script

Hi Guys
I would like to know wether anyone has successfully been able to call a Web Service from within an
e-Sourcing script? If you have, can you please share your experience and code?
Thank You

Hi Faaiez -
As with any use of Web Services, however, you should carefully consider the security issues that may come up. How, for example, will the Web Service server validate that the Web Service client (E-Sourcing) is properly authenticated? Will password information be included in the web service call? You will find that it is very easy to make a web service call, but I would encourage you to carefully consider security before implementing a productive solution.
Web service calls can be made using raw Java web service APIs from the open source Axis library which is included with E-Sourcing; this approach is slightly more difficult to code, but very dynamic. Web service calls can also be made using proxies. In one solution that I worked on, we generated java proxies for the web service, compiled those proxies into a Jar file, and included that jar file as a custom jar in E-Sourcing. Let me provide a few more details on each of these approaches.
Using raw java web service APIs that are part of the Service and Call classes, I prototyped a web service call to Googles sample spell checker web service. Here is the code:
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
import javax.xml.rpc.ParameterMode;
import javax.xml.namespace.QName;
String endpoint = "http://api.google.com/search/beta2";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new java.net.URL(endpoint) );
call.setOperationName( "doSpellingSuggestion" );
call.setOperationName(new QName("urn:GoogleSearch", "doSpellingSuggestion"));
call.addParameter("key", XMLType.XSD_STRING, ParameterMode.IN);
call.addParameter("phrase", XMLType.XSD_STRING, ParameterMode.IN);
call.setReturnType( XMLType.XSD_STRING );
String ret = (String) call.invoke( new Object[] { "googlekey", doc.getDocumentDescription()} );
doc.setDocumentDescription(ret);
This block of code does a very simple thing...it calls the Google "doSpellingSuggestions" web service with two parameters: a key provided by Google, and a string for which the spelling suggestions should be generated. I used the current document description as my sample string for the web service and I put the results back into the document description - remember, this is just showing how you can call the web service, not doing anything really intelligent or useful from a business perspective
There is nothing special to E-Sourcing about the above code...this is really just using the Axis java classes to call a web service.
The second approach that can be used is to generate Java proxies for the web service calls. The open source Axis library includes a tool called "wsdl2java". Using the WSDL for the web service, you can generate Java proxies. Java classes will be generated by the tool; these Java classes will then need to be compiled and included in E-Sourcing as a custom jar. Once they are part of the E-Sourcing deployment, they can be called like any Java API. If you were to examine the generated code, you would notice that it looks a lot like the raw web service code shown above...the generated classes really just provide a simpler interface to the same functionality.
You can see this information and other E-Sourcing information at my blog at: http://www.sunshinesys.com/

Accessing external web service with non-constant URL

Hello, all
I am looking in the documentation on accessing external web services, but either I am looking in the wrong place, or the documentatoin is lacking info.
My clients have several web services in the local network (regular services, not DB-based), the have the same interface, but different URL's.
Versions of the DB are 11, 12, and 16.
First of all, I do not see in the specs an option for a non-hardcoded URL. The logic says that this has to be possible, but I cannot find it.
Second, I need to see an example of accessing an XML or JSon based service, I cannot find it in the specs either.
Can anyone point me to a document with examples?
Thank you
Arcady

The following will call a web service with whatever URL you pass in as the argument "myurl". I think that is what you are looking for.
CREATE PROCEDURE cli_test2( myurl LONG VARCHAR )
RESULT( httpheaders long varchar, httpvalues long varchars
URL '!myurl'
To deal with the resulting data in XML, use the OPENXML() function.
eg. To turn an XML list of employees that looks like this:
<root>
<row EmployeeID="102" Surname="Whitney" GivenName="Fran" StartDate="1984-08-28"/>
</root>
into a table of results, you would do this (where xmlgetemplist() is the web service call):
CREATE OR REPLACE PROCEDURE xmlgetemplist() RESULT( httpheader long varchar, httpbody long varchar)
URL 'http://localhost/demo/xmlEmployeeList'
TYPE 'HTTP:GET';
create variable res long varchar;
-- call the web service
select httpbody into res from xmlgetemplist() where httpheader = 'Body'
-- extract the XML elements into a SQL result set
select * from openXML( res, '/root/row' ) WITH ( EmployeeID INT '@EmployeeID',
       GivenName    CHAR(20) '@GivenName',
       Surname      CHAR(20) '@Surname',
       PhoneNumber CHAR(10) '@Phone');
To deal with the resulting data in JSON, use the sp_parse_json() procedure.
eg.
To turn a JSON formatted list of employees that looks like this:
"EmployeeID": 102,
"Surname": "Whitney",
"GivenName": "Fran",
"StartDate": "1984-08-28",
"TerminationDate": null
into a table of results, you would do this (where jsongetemplist() is the web service call):
CREATE OR REPLACE PROCEDURE jsongetemplist() RESULT( httpheader long varchar, httpbody long varchar)
URL 'http://localhost/demo/jsonEmployeeList'
TYPE 'HTTP:GET';
create variable foo long varchar;
--call the webservice
select httpbody into foo from jsongetemplist() where httpheader = 'Body';
--turn the json result into a structured array of data
-- this step is required because of less structured nature of JSON
call sp_parse_json( 'output_array', foo);
--extract the JSON elements from the output array into a SQL result set
SELECT output_array[[row_num]].EmployeeID as EmployeeID,
               output_array[[row_num]].SurName as SurName,
               output_array[[row_num]].GivenName as GivenName,
               output_array[[row_num]].StartDate as StartDate,
               output_array[[row_num]].TerminationDate as EndDate
FROM sa_rowgenerator(1, CARDINALITY(output_array))
Hope this helps,

Calling SharePoint Web Services from PL/SQL

We are trying to call SharePoint Web Services with UTL_DBWS or UTL_HTTP. We are able to call some test web services, but when it comes to using SharePoint services, we keep getting 401 errors..even when we use set_authorization.
Has anyone been able to use UTL_DBWS or UTL_HTTP to call SharePoint web services? If so, can you point us in the right direction?
Thanks

AB,
I didn't realize you cannot attach documents to your post. You will have to provide me with an email address that I can send the documents to. They are a little rough (ie not commented etc) but they do illustrate the point. The basic idea is to build up the payload of the soap envelope using pl/sql. Meaning as I loop through the cursor I use each record in the cursor to build an xml string. This string of xml becomes the payload of the soap message. This could also be done using xml functionality provided by the db meaning xmlelement, xmlforest etc. The issue I ran into was the size of the message. That is why I elected to build the xml message by string concatenation as I moved through the cursor.

Error when calling Java Web Services from ABAP.

Hello experts:
    In my project, I will call Java Web Services with ABAP coding. With WSDL, I generated a proxy class and created a HTTP connection (t-code: SM59) and a logical port (t-code:lpconfig) for this proxy class. But when running, I would receive the folllowing errors:

   If I used HTTPS, there is no problem.

Bob

Hi Bob,
It might be the possibility that your java web server is configured to listen only on HTTPS.
If your HTTPS is working fine, then first check with your JAVA server for HTTP connectivity, then try it calling through ABAP.
