Webservice with no VALUES field - Can not be used by ABAP !

have a problem with webservices called by ABAP.

In order to use OT webservices, i use the OT WSDL to generate ABAP proxies. With proxies I'm able to authenticate, to create folder and to create document in Opentext apparently with no issue.

Unfortunately, there is an exception reguarding the AttributeGroup management.

In all the structures generated by the proxies, the metadata section contains these fields

<urn1:metadata>

<urn1:AttributeGroups>

<urn1:DisplayName></urn1:DisplayName>

<urn1:Key></urn1:Key>

<urn1:Type></urn1:Type>

<urn1:Values>

<urn2:Description></urn2:Description>

<urn2:Key></urn2:Key>

</urn1:Values>

</urn1:AttributeGroups>

</urn1:metadata>

As you can see, every attribute has only 2 fields : DESCRIPTION and KEY. The most important field VALUES is imissing.

This is a real big problem because without that field, I'm not able to set any metadata.

I thought that problem was limited to ABAP and SAP R3 but even trying with other products (i.e. SOAPUI) I had the

same problem. In SOAPUI, I discover that changing the xml in the following way (adding VALUES tag and adding the xsi:type definition), problem can be solved:

<urn1:metadata>

<urn1:AttributeGroups>

<urn1:DisplayName></urn1:DisplayName>

<urn1:Key></urn1:Key>

<urn1:Type></urn1:Type>

<urn1:Values xsi:type="urn2:StringValue" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<urn2:Description></urn2:Description>

<urn2:Key></urn2:Key>

<urn2:Values></urn2:Values>

</urn1:Values>

</urn1:AttributeGroups>

</urn1:metadata>

Unfortunately I can't do the same in ABAP when I only can use the proxy structures generated from the OT WSDL.

I hope someone can support me because I think that webservice must be consumed even by SAP. I can't believe that OT has developped something with this limitation.

I have the same problem. Is it possible to fix this issue or having a workaround?

This is not a limitation of the webservices, but a limitation of the tools being used. The structure that is being generated is the exact definition of a DataValue object. However, the objects that are actually used inherit from the DataValue object (ie. BooleanValue, StringValue, etc.) which define the missing Values field. So the problem is with the tools not being able to understand polymorphism (ie. a BooleanValue is a DataValue).

Hi Roberto,

I also have the same issue with SOAP UI. I can test all other webservices. I have written a JAVA based client to populate the metadata and attributeGroups. I know that you are using ABAP. I am using a java based integration tool and when I created all the SOAP request structures from XSDs of the webservice, I couldn't find this values tag to set. So, I took the .jar of the SOAP request structure from the project package. I added that jar in the classpath and populated the metadata. You can try the similar approach.

Thanks,

Kapil

Hi all,

One of my customer experience the same problem not able to add category attribute data on a CS item where CS 10.5 is installed. So it seems that this problem still occurs or did somebody found a solution for that ? If yes, I'm more than interested

Many thanks

Hi, Could you please share the web services you used to create folders? I am looking at the exact requirement. Did you have to call multiple web services ?(Authenticate, Create..) Please share the wsdl URLs if possible? Did you test them with external standalone tools before you used them with ABAP ?Thanks a lot for all the info.Santhosh

eLink User

First see if you are in the right forum this link will help you navigate the setup as well as sample code

https://knowledge.opentext.com/knowledge/cs.dll?func=ll&objId=62345549&objAction=browse&viewType=1

This one called ELS API is for customers who have integrated SAP with LIVELINK (Content Server)

https://knowledge.opentext.com/knowledge/llisapi.dll?func=ll&objId=16060349&objAction=view

ELS API offers access to the Document Model your project is using and it will take care of SAP authorizations all

the nine yard you have to take with ABAP /Java code.

Both API's use Oscript internally(you can use any WS Language you are familiar with) and do work in Livelink and are similar and ELS is typically used in Extended ECM scenarios.

Thanks eLink for your reply. I am new to this Open Text Products. We have Content Server 10.5 but we are no way integrated with each other. Hence I am trying to use Web Services offered by Content Server and looking for the documentation/help on available services. I have seen some places on help documentation like http://localhost:8080/cws/services/Authentication?wsdlSo I just wanted other service definitions that are available and any documentation on them. Please let me know if you can help with it.ThanksSanthosh

Did you not see the first link.If it is not apparently clear OT's code or the WSDL you say is what you have to deploy.Sensing that you need to run on Tomcat here's how I would do it.

Talk to your Livelink administrator and find you have an empty server that has TC or IIS.Take the files under <OTHOME>\webservices\Java deploy the war in that.If you want the IIS version use that.Your client code can be any WS language but the fact that the WSAPI should be deployed either on IIS or TC.The installation files are part of livelink installation so only you or your organization can deploy them
Connect your livelink server by the config file if your LLserver is dfferent from your wsapi server the server IP or name and the lapi port usually 2099.
Now source the WSDL using localhost or boxname.
If you have a spare IIS you can do the same.

Fact is that your livelinkserver holds the key to the kingdom.Once you set it up,use the samples OT provide and program away.

If you want you can read my blog here https://appukili.wordpress.com/2014/10/18/what-is-enterprise-web-services-a-k-a-content-web-services/

I sometimes supplement OT's great effort in the KB by helping out

Hi,

Now I am able to consume Authenticate, Document Management webservices. I am able to authenticate. I get the token back. Could you please share how you used this token when you are creating the folder? I could not see an input parameter or anything for this token. How do they map to message types(strucutures, input parameters)?

Thanks

Hi Santhosh,

I see no point in extending further help.There are 4 examples that OT has given for you to try.Have you done any of them?

jdonpaul

Hello Santosh,

Once you have a token from the authentication method that you used, you can use that token on every subsequent web service method that you call. Examples on how to authenticate and use that token can be found here:

https://knowledge.opentext.com/knowledge/cs.dll/Open/45500683

You can use the samples that we provide to generate the SOAP packages. By using Fiddler or Wireshark, you can then see how the SOAP packages are formed. Once you have captured those SOAP packages, you can then move on and use whatever tool you are using to generate those SOAP packages based on the SOAP packages that you have captured.

Hope this helps,

Jerome

Hello Appu,

If you dont see a point and dont know how to answer probably its worth everyones time to keep quiet.Please dont extend help. Please dont show your attitude on public forums. Keep it at your home.

I have knowledge on Java and ABAP. My question is regarding ABAP. Do you know anything about ABAP? Have you seen any samples on ABAP on OT Documentation? I have not.

Santosh_Manchala

Thanks Jerome. I am sorry I was not clear enough on my question. This is regarding ABAP not Java. I have gone through Java samples before posting this. There is nice API/Samples available if you are using C# or Java client but not for ABAP.

Also the created client on ABAP has some generic fields. It is not clear on how to include SOAP Header in a method. As it is generated method, it does not even have any documentation as well.

For example from Java Side I have already seen this piece of code: I will research more thanks for your help.

// Create the Authentication service client
Authentication_Service authService = new Authentication_Service();
Authentication authClient = authService.getBasicHttpBindingAuthentication();

// Store the authentication token
String authToken = null;

       // Call the AuthenticateUser() method to get an authentication token
       try
       {
           System.out.print("Authenticating User...");
           authToken = authClient.authenticateUser(USERNAME, PASSWORD);
           System.out.println("SUCCESS!\n");
       }
       catch (SOAPFaultException e)
       {
           System.out.println("FAILED!\n");
           System.out.println(e.getFault().getFaultCode() + " : " + e.getMessage());
           return;
       }

       // --------------------------------------------------------------------------
       // 2) Store the metadata for the upload in a method context on the server
       // --------------------------------------------------------------------------

// Store the information for the local file
File file = new File(FILE_PATH);

       if (!file.exists())
       {
           System.out.println("ERROR!\n");
           System.out.println("File does not exist at : " + FILE_PATH);
           return;
       }

       // Create the DocumentManagement service client
       DocumentManagement_Service docManService = new DocumentManagement_Service();
       DocumentManagement docManClient = docManService.getBasicHttpBindingDocumentManagement();

       // Create the OTAuthentication object and set the authentication token
       OTAuthentication otAuth = new OTAuthentication();
       otAuth.setAuthenticationToken(authToken);

       // We need to manually set the SOAP header to include the authentication token
       try
       {
           // Create a SOAP header
           SOAPHeader header = MessageFactory.newInstance().createMessage().getSOAPPart().getEnvelope().getHeader();

// Add the OTAuthentication SOAP header element
SOAPHeaderElement otAuthElement = header.addHeaderElement(new QName(ECM_API_NAMESPACE, "OTAuthentication"));

           // Add the AuthenticationToken SOAP element
           SOAPElement authTokenElement = otAuthElement.addChildElement(new QName(ECM_API_NAMESPACE, "AuthenticationToken"));
           authTokenElement.addTextNode(otAuth.getAuthenticationToken());

           // Set the SOAP header on the docManClient
           ((WSBindingProvider) docManClient).setOutboundHeaders(Headers.create(otAuthElement));
       }
       catch (SOAPException e)
       {
           System.out.println("Failed to set authentication SOAP header!\n");
           System.out.println(e.getMessage());
           return;
       }

I think I have the answer. We have generic interface/method in ABAP. After seeing Java code, I can do the same on ABAP side.

For anyone else in future....

if_wsprotocol_ws_header, you have two method SET_REQUEST_HEADER and GET_RESPONSE_HEADER to access soap header

Thanks

jdonpaul

You're welcome Santosh.

We do not have any ABAP examples on how to use our web services. The closest that we have is probably delivered with the SAP solutions that we offer or the fourms found here:

https://knowledge.opentext.com/knowledge/llisapi.dll/Open/46226567
https://knowledge.opentext.com/knowledge/llisapi.dll/Open/17324886
https://knowledge.opentext.com/knowledge/llisapi.dll/Open/17324886
https://knowledge.opentext.com/knowledge/llisapi.dll/Open/61656482

You would probably need to search for the abap code within and see what we did. Another possability is to look at the SAP forums. They may have additional information for you as well.

Hope this helps.

Hi Santhosh / Team ,

I am having the same requirement to read the attchment from the open text content service folders and display it in the SAP Fiori application. I cannot use JAVA here. I have to go with ABAP Proxies and then Consume it in gateway Layer to get the attachment content.

I am trying to test the Open text web services Authentication , Document Management and Content services in SOAP UI Client to confirm the methods and paramters to be passed. Once it is successfully identified i will be creating abap proxies for it.

In SoapUI I am able to get the Authentication Tocken from the Web service Authentication & Method Authenticate User. But i am unable to proceed further. As i am new to open text and as well as Web services , please help me here with the sample paramters,headers to be set in Soap wsdl methods to test it in the soap ui client .

As i have gone through the blogs with sample Java Code , we have to pass this Auth token to document management service and get document id and then use the ID to get the content by means Content service, method Downloadcontent. But when i am passing this auth token to any methods it is giving me the error.

Kindly let me know the sequence of steps to be followed for this as you might have already implemented this . Even a small information will be much of helpful.

Thanks & Regards,

Saranya Sakthi,

Hi Hans,

Yes , Our system is installed with XECM i hope. And we are able to virtaully see the open text Livelink folders and able to attach the documents to the open text server via SAP GUI Business workspace. Please find below the screenshots.

Our Requirement is to get these documents to fiori application . i have debugged and backtraced how it is been rendered in this workspace .

But still, we are not able to get the exact parameters or methods as it is all displayed as dynamic numbers.

Can you please let me know , the web service with its parameters , or any FM or RFC is there for direct consumption.
