Authentication : accessing an LDAP via an external web service ?

Hi,
I know it is possible to use an external web service to authenticate a user on a portal.
But I would like to know it is possible for a user to :
- open hiw browser and navigate to the Enterprise Portal
- the portal is asking a user and password
- then the portal call a web service giving the user/password
- the web service (enternal and already existing) check the authentication through the LDAP
- the web service reply OK/NOK to the portal with a SAP USER ID (or another information)
- the portal if authentication ok send a logon ticket to the user
I didn't find any clear information telling it is possible.
So if someone can help on this matter ...
Many thanks.

Hello,
First, thank you Sandor for your answer.
I understand that it is possible to create a BPEL process that exposes multiple operations/messages. This would be exactly what I need: a single process (web service) that will expose many operations. Could anyone, please, point me to such an example?
So far I thought that there is possible to have only one operation exposed with a BPEL process, what is delimited between the receive/reply blocks (in the synchronous case).

Accessing BPEL processes via a proxy web service performance issues

Hello,
I have more BPEL processes implemented, each such a process implementing business functionality in a certain domain (generally, a domain has more business processes).
The request was to provide a single web service for each domain. It means that all the business methods (processes) in the same domain should be accessed through the same web service. This request doesn't make possible to expose the BPEL processes themselves as web services that could be directly consumed by different clients of the application.
The alternative will be to implement the "domain" web services through a Java class, for instance. With this approach, the Java based domain web services will expose the needed business methods to the clients. And the Java class will get the request input parameters and will call the corresponding BPEL process via SOAP. This scenario would be fine, but... this approach would imply a supplementary marshalling/unmarshalling process at the domain web service level. The data returned by the BPEL processes could be very large and in such a situation the Java based domain web service will introduce an important performance drawback.
Is there any other solution to this case that will allow the using of a "proxy" domain web services that will not introduce any important drawback via marshalling/unmarshalling?
Many thanks in advance!

Hybrid Lync - External Web Services?

Can anyone tell me if the external web services, provided by the on-premise Front-End server are ever used in a Lync Hybrid deployment?
If not, how is "meeting content" that is created in a Lync on-premise meeting accessed by Lync Online users?
Is the content in this scenario shared over media between the Edge servers or is it accessed via the external web services urls (i.e. reverse proxy)?
I'm trying to determine if i need to setup the external web service access from outside (internet) into the on-premise Lync deployment to support a Hybrid deployment, as in this particular case none of the users will be external.

Yes you need it. Even if a Lync user on premises is never external, if they want to invite an external person to a meeting or use mobile client internally, this will be necessary.

Invoking an external web service through a JCD with Basic Authentication

Group,
I am trying to invoke an external web service (written in ASP.Net) from a jcd (5.1.2). The web service is guarded by Basic Authentication. I have entered the crudentials into the External Web service environment component and deployed the project. I receive the following error from the .invoke() method:
request requires HTTP authentication: Unauthorized
I have tried the same request through SoapUI using the same crudentials and get back the response correctly. Has anyone tried invoking an external web service with basic authentication through a jcd in 5.1.2 before?
One other item of note. I have another jcd calling a different external web service deployed on the same domain. I hope that this isn't interfering with the execution of this service as it doesn't require any crudentials to execute.

Hey Chris.
I am just starting to write a jcd that calls an external web service but cannot find any sample code nor instructions on how to do it in the supplied documentation. Could you send me a code sample from your one?
Cheers
Matt

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.

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,

Consuming an External Web Service using HTTPS and WS Security

Hello everyone,
I'm having a problem setting the security information in a SOAP header using a generated ABAP Client Proxy to consume an external web service that requires a User ID and Password in the Header section of the SOAP message. I need to use HTTPS. I'm on a WAS 7.01 SP08 system so from my readings, SAP is supposed to be able to add the username and password into the header section of the message. I can't seem to get SAP to add this information added to the header.
Here are the steps that I have taken to set the security values.
1) Created the client proxy from the WSDL in SE80. Basic Authentication on the Configuration tab was turned on automatically.
Note, Transport Security is set to None. I cannot change it.
2) Created an outbound set user name profile in transaction WSPROFILE with the appropriate username and password.
3) Added the profile to the default port in transaction LPCONFIG as an outbound under the WS Security section of the screen.
When I called the external Web Service, I got back the following error message:
com.ibm.wsspi.wssecurity.SoapSecurityException: WSEC5509E: A security token whose type is [http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#UsernameToken] is required.
So, after reading through this Forum, I saw that I needed to use the SOAMANAGER. I set up a Proxy in the SOAMANAGER and manually created the Logical Port. This was the only way I could figure out how to set the Authentication Settings in the Logical Port to "User ID / Password". I then entered the User ID and Password.
However, I am still getting the same error message. I feel I am close but missing some small configuration to tell SAP to use WS Security with a Username token.
I'm not sure what I'm doing wrong, so any help would be appreciated.
Thanks,
Stephen

I had this error again so I thought I would post my solution:
The issue is SAP needs to know the certificates being used by the web site being called. These certificates are automatically installed in your browser but need to be manually installed in SAP. This is what I did:
How to find/install new certificates
Make sure you run Internet Explorer as an Administrator so you can export the certificates
Go to the web site that SAP is trying to call in Internet Explorer
Double click on the lock in the address bar
View certificates
Find the certificates that are being used
Tools --> Internet Options --> Content --> Certificates
Click on the “Trusted Root Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Click on the “Intermediate Certification Authorities” tab
Find the certificate identified in step iii
Export as a CER certificate
Go to STRUST in SAP
Import the Certificates in the “Anonymous” or “Standard” SSL client
Save

External Web Service - User and password in HTTP header

Hi!
How is it possible to add user and password in the HTTP header in a external web service call?
I have created a "Portal Service from WSDL file - Client side" with the wizard in SAP Developer Studio. I following the Java Development Guide - Web Service Security, and use the <i>secured service connection</i>. I have also created a new <i>System Landscape</i>, but should the new system be based on HTTP, my own PAR or what?
How can I check that the user and password is added to the HTTP header or the SOAP envelope? Do I have to scan http traffic with a proxy as Paros or can I find the request sent from SAP EP in the logs?
Cheers

Hello All,
I have been struggling a bit while putting a reasonable security framework on a jax-rpc style web service. I'm using JWSDP1.2 to set up the webservice. I've tried to outline my problem below. Please correct me where I'm wrong.
I've been through the Sun's WS tutorials, but they are not really clear on security. However, from them I surmised that there are two decent authentication techniques. HTTP Basic and mutual authentication (MA) . Both have their drawbacks though. HTTP Basic suffers from poor encryption while MA is a bit difficult to set up on both client and server sides. Another problem with MA is that there is no central repository for users/passwords.
OK, what I would really like to do is use my own user database to verify users/passwords i.e. use a HTTP Basic like authentication (but at application level) but run it over SSL for encryption. It seems simple, but is it possible?
Also, I have noted that when I use HTTP Basic on the service side, and use a java client, then setting username/password has no effect. In other words, I can always access the web-service, even with wrong username/password.
Sorry for the long post. Hope someone can help. Thanks.

OEDQ invoking external web service

Hello:
Does OEDQ have the capability of doing one of the following:
1. Pushing data to an external application? (Ie: Pushing data to SOA application)
2. Invoking an external web service (WSDL) by an external application? (Ie: Invoking a SOA WSDL)
Thank you.

Yes, both of these can be done.
EDQ's export capabilities can be summarized as follows:
- Export to pretty much any kind of file, including (but not limited to) delimited text files, fixed width text files, XML (in virtually any format), Excel files, binary files etc.
- Export to pretty much any kind of database (Oracle, SQL Server, Sybase, DB2, DB2 for iSeries, Access, MySQL, PostgreSQL etc.)
- Write to a message queue via JMS
- Respond to a web service request
EDQ does not normally call update APIs directly, though it can be made to do so.
Web services can be called in the middle of an EDQ process where required - examples where this has been done include calling a Dun and Bradstreet web service to enhance company data, and calling e-business suite web services.

Mike

Hi Luis,
If you see closely, the productID is actually a concatenation of the areaID and the productID. The reasoning here is that a product can be in multiple nodes of the product catalog and one would need to specify the product on a particular node for the direct URL to work.
On a client site, we came up with a better solution by creating a new FM to retrieve the specific areaID and productID for a product. This FM could be called by extending the webshop. Then a .NET program was written to re-direct a shortened form of the URL to the long URL and therefore the specific product in the product catalog. Eg.: http://yyyyy.com/b2c/b2c/product would be automatically redirected to http://yyyyy.com/b2c/b2c/init.do?shop=<shop name>&areaID=<area Guid>&productID=<product Guid>, something similar to the concept behind "tinyurl.com". A point to remember here is that this would work only for the B2C webshop.
Hope this helps.
Cheers,
Ashok.

Error when calling an external web service (blank soap action)

I did a lot of searching on this message and did not find an answer. Most of the issues i found related to XI/PI, which we are not using.
There is a web service created outside of SAP for which i generated (from the WSDL) a proxy class in my DEV system, client 050, a few years ago. This was subsequently moved to QA and production, and all is working fine.
Now, i want the same web service to work in client 100. I created the logical port, and the RFC destination, but when i try to call the web service, i get the following error
Server did not recognize the value of HTTP Header SOAPAction
Since only the basis group around here can access the logical port definition,and rfc destination, i have no idea where this information should be set up. I should not have to reimport the WSDL, since the proxy was imported from DEV to QA and it is working in QA client 050. There is something i need to set up, specific to client 100, and i am missing it. I looked in SOAMANAGER, and i didnt see anything even set up there for client 050, so i did set up anything for client 100.
Any help would be appreciated.

I tried adding the web reference in a console app and works fine. In the plugins this can't be done, because the plugins are deploy in database.
I tried another basic test using ChannelFactory. Only want to retrieve some entity through the external web services:
IPluginExecutionContext context = localContext.PluginExecutionContext;
IOrganizationService service = localContext.OrganizationService;
ITracingService tracer = localContext.TracingService;
try
BasicHttpBinding binding = new BasicHttpBinding();
binding.Name = "BasicHttpBinding_IAxxisWcfServices";
binding.Security.Mode = BasicHttpSecurityMode.None;
binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
EndpointAddress endpoint = new EndpointAddress(@"http://*****.svc");
ChannelFactory<IAxxisWcfServices> factory = new ChannelFactory<IAxxisWcfServices>(binding, endpoint);
IAxxisWcfServices channel = factory.CreateChannel();
var entity = channel.FindByEntities(new CRM.Application.Context.Dtos.Asegurado( { CrmGuid = "7C3E96C6-C3BC-E411-80DF-0A736AE14667" }, null, new CRM.Framework.Session() { User = "***", Password = "***" });

throw new InvalidPluginExecutionException(ex.Message);

Error in Invoking External Web Service in BPEL

Hello,
I have a Temperature Conversion Web Service deployed on an external server.
I want to invoke this Web Service in my BPEL process.
I got the wsdl loacation of the Web Service as "http://webservices.daelab.net/temperatureconversions/TemperatureConversions.wso?WSDL" and then in my workspace, I created a Web Service out of that WSDL.
My idea was to create a web service out of that WSDL and then to deploy that web service on SOA server so that i can invoke that deployed service in my BPEL process, but when i am creating a web service out of that WSDL , and trying to test the webservice in my local oc4j, i am gettting a fault exception.
Am i doing anything wrong ? Is there any other alternative to call a external web service in BPEL?
Thanks
Nutan

Hi,
you are on the wrong track....
Open your BPEL. Put the http://webservices.daelab.net/temperatureconversions/TemperatureConversions.wso?WSDL into a PartnerLink and wire an invoke against this PartnerLink....
Put the parameters via assign into the variables.
Done...
Why do you want to create an interal webservice and invoke this one via BPEL? Do you want to invoke the external webservice from the internal one?

Consuming external web services in CAF

Hi there,
I am trying to set up a show case where a composite CAF app (exposed via WD or VC) uses SAP web services as well as external services. In this case, I chose to use the Fedex web services (http://fedex.com/developer).
Everything works fine, I am able to import the webservice using the locally stored WSDL into my composite app, apply the mapping and implement the application service......build, deploy...all good.
The problem occurs when trying to create the physical destination (under nwa/destination template management). NW expects a pointer/url to the wsdl or wsil file, but Fedex doesn't provide that via http. Putting the wsdl on a different web server doesn't help either as the SOAP call will be routed to the same host where the wsdl resides (in this case NOT the fedex system).
Is there any way to circumvent the WSDL retrieval with external web services in Netweaver ? One alternative solution could be to use the Netweaver Service registry and publish the fedex wsdl to that, but I would like to avoid that as we haven't configured the SR at the moment.
Thx, Nick

Looks like I don't need it necessarily.
There seems to be a bug in NW/CE 7.1. When defining a destination which points to a WSDL file which in turn points to a different server for SOAP messages (ServicePort), the endpoint URL is incorrectly defined.
WSDL URL: http://www.server1.com/test.wsdl
SOAP URL/Port: http://server2.com/webservices
the server tries to dispatch the SOAP call to http://server1.com/webservices which can't be found.
In CE 7.1.1. though, that bug is fixed, and everything works fine without the need to publish the remote service (wsdl) to the SR and to subsequently query it.

I implemented a portal application which consums a external Web Service with NWDS 7.2.
The Webservice access works fine when I test it in a Java-Main Class.
If I deploy the application in a portal then I get the error:
java.lang.NullPointerException: while trying to invoke the method java.net.URL.getProtocol() of an object loaded from local variable 'tmpUrl'
It seems that my service_client-class has the problem to call the wsdl if the application is in portal:
static {
    java.net.URL url = null;
    try {
               java.net.URL tmpUrl = SERVICEClient.class.getClassLoader().getResource
              ("wsdl/com/sap/test/SERVICE.wsdl");
              url = new java.net.URL(tmpUrl.getProtocol(), tmpUrl.getHost(), tmpUrl.getPort(), tmpUrl.getFile());
    } catch (java.net.MalformedURLException e) {
      e.printStackTrace();
Can anybody help me?
Thanks, Thomas

Hello Thomas,
I got the same error. In my case I used an Enterprise Application Project for the developement of my Portal Service. The portal service itself was calling an external webservice.
The reason in my case lies behind the generation of the EAR-File with the NetWeaver Developer Studio). Inside the generated EAR-File the WSDL-File was always missing. In consequence "
java.net.URL tmpUrl = SERVICEClient.class.getClassLoader().getResource
              ("wsdl/com/sap/test/SERVICE.wsdl");" is always "NULL".
and "tmpUrl.getProtocol()" leads to the NullPointerException.
So I copied my wsdl-folder / package with the wsdl-file inside the {application}.ear / {application}.war / WEB-INF / private / lib / {application}.jar and everything works fine:-)
Regards
Steffen
PS: Today I found a better way without copying the wsdl-file into the EAR-File. I just didn't use the Enterprise Application Project for the developement of portal services anymore. If you look inside the generated EAR-File, you can see, that you can develop the portal service also by using a simple Dynamic Web Project wrapped by an Enterprise Application Project:-)
(Rem.: Don't miss the portalapp.xml deployment descriptor).
If you deploy the Enterprise Project the WSDL-File is always inside the generated EAR-File :-)
