REST Webservice from Workbench

Hello,
I have a simple requirement, I need to invoke a REST webservice from a workbench process, and store the output in a variable (content is XML data to render in a form).
I tried using the Invoke WebService component, but it is only allowing SOAP-based webservices.
How can I achieve this? Is my approach wrong? The idea would be to get a user input throught a human-centric process (a document id), then pass that to a WS that will marshall the XML data and the render the form based on the XML data...
Thanks for your help!

I found one link

but it is not working out...i didn't get what it saying? Please help me out

Calling REStful webservices from Designer

Hello,
I know we can connect to a webservice via wsdl type data connection, but has anyone tried calling Restful web service by any chance?
If so please let me know how can we do that.
Thanks

Hi Paul,
Are RESTful services supported in the newest version of LiveCycle? If so can you provide a short example? Thank you,

RESTful webservices invocation from OSB.

Can some one please explain the best way to develop the OSB service to invoke the Restful services.
1. Only proxy service is enough to handle the request, no need of business service?
2. when moving the code from one env to other, we use a business service to update endpoint url which is the common approach we generally follow, to make the osb service loosely coupled. how to use the business service when invoking the restservice? does we have the base uri value in the transport url and will get appended with the relative-uri value which we frame as part of the request in the outbound variable in the proxy settings?
3. when invoking the rest service do we need to append all the request message to the url itself or the request can be passed separately as request body and the main rest uri will have only the key fields as part of the relative-uri?
4. If we receive huge request message does the URL support the entire request?
5. how the response/error will be returned when calling the Restful webservice?
I am assuming this appraoch. Can some one please confirm does this approach works with RESTful service invocation from OSB.
Request processing:
Source System request-> Proxy Service -> Transformation to end system specific -> Business service (with base-uri -> http://mainappl.com/web/cmr/{relative-uri from outbound transport}) -> endsystem
Response processing:
endsystem Response/Error -> Business Service -> Proxy Service -> transformation to source system specific -> source system.
Please advice which is the best approach to follow while invoking the RESTful webservices from OSB.
Thanks..

Hi,
Thanks for the update. Can you please explain the above mentioned approach works or how it should be?
I have one requirement, can some one explain the implementation for this:
I have one element which is of type unbound. I need to map this element to a single enelement value by separating each element value with a ;, before that I need to check wheteher this element(s) are present in the request then need to appened all these element values to a single element and the end of this element need to append default values.
Scenario:
<student>
<name>asd</name>
<address>
<street>street1</street>
<street>street2</street>
<street>street3</street>
||
||
</address>
to be mapped it to:
<student>
<field name="NAME">asd</field>
<field name="ADDRESS">street1;street2;street3;default1;default2;default3</field>
</student>
Here need to check if street names are present in the request xml, if yes ned to assign it to ADDRESS as mentioned above if street names present or not need to append the default values at the end to the ADDRESS field.
Thanks in advance.

REST Webservice invocation from Java

Hi Guys,
I am developing an application that needs to invoke a REST webservice and submit XML data to it. The server will then process the request XML data, and return a result, etc.
I have never worked with REST and have spent hours researching it on the NET. I have done SOAP calls in the past, but this seems to be eluding me some what.
Does anyone know of any useful links that explains REST implementation, frameworks / jars needed, or possibly even an example or two that shows me how to submit data via REST to a URL (would be first prize :) ).
Any help would be greatly appreciated.
Many thanks
Mark

Url service data control - problem while POSTing to a restful webservice

Hi,
I am trying to call a restful webservice to add a new employee .I have created the url service data control. The service method consumes XML.
When i am creating the url service datacontrol I selected the http method as POST and giving the servicepath and servicename as the source. After providing the xsd's path and all , when I test the url connection, I am getting the following error message:
URL Test: Received Error: Method Not Allowed
This might be because the clicking of the test url button is sending the get request, but the actual method is POST.
Now under the data controls navigator, If i view the newly created data control, i could see the loadData(Object) method which i assume is for retrieving the data from the service. But since i have mentioned the method as POST, why such a method is created? Also if its there, can I use the same for insert and update? I have used this loadData (Object) method to create a button which calls the webservice upon click. Under the data control property inspector, i changed the supportsupdate attribute's value to true. But when i am trying to save the employee from the jspx page, I am getting the following message in the integrated weblogic's log
Couldn't get access to the data source. Cause Unsupported Media Type exception in rest service
And on the server side I am getting the following error message:
No message body reader has been found for request class Employee, ContentType application/octet-stream.
I think the request is not going as XML. But while creating the datacontrol i have specified the xsd document for the iput xml request. Does ADF automatically creates the XML from the input parametres? If it does not, then what could be done to achieve that? The default actionListener of the submit button is #{bindings.loadData.execute}. Do i have to override it to send the XML request? Or have I missed anything in trying to achieve what i intend?
I had refered this link for reference :

Hi Frank,
I had specified the HTTP method as POST as well as PUT. But the same error is appearing in the both the cases.
URL Test: Received Error: Method Not Allowed
And when I am clicking on the 'Test URL Connection' , I can't see any option of selecting the HTTP method. This option only appears in the step 2 of creating the URL service data control where we mention the URL endpoint and the source.
What could be the reason for the error.

Hi all,
Can anyone please suggest on how to call the RESTful webservice (which is used by our client) by passing an XML payload from a PL SQL stored procedure? It is for the authentication purpose. And the username and password has to be passed as the XML payload to the RESTful webservice . Please help, it's a bit urgent.

How to set username and password before redirecting to a RESTful webservice

I am a .Net developer who has developed a webservice used by my ColdFusion colleagues. They are using ColdFusion 9 but I'm not sure if they have incorporated any of the newer features of ColdFusion in their apps. Here is a snippet of how they have been invoking the webmethods:
<cfscript>
                     ws = CreateObject("webservice", "#qTrim.webServiceName#");
                     ws.setUsername("#qTrim.trimAcct#");
                     ws.setPassword("#qTrim.trimpwd#");
                     wsString=ws.UploadFileCF("#qTrim.webserviceurl#","#objBinaryData#", "#qFiles.Filename#", "Document", "#MetaData#");
            </cfscript>
As I understand things, the .setUsername and .setPassword correspond to the Windows credentials the CF Admin set when the URL of the .Net webservice was "registered" and given its "name" (for the CreateObject statement above). I have 4 webmethods that are all invoked in this manner and this SOAP protocol works adequately for us. Please note that this ColdFusion web app authenticates anonymous remote internet users by prompting for a username and password and compares them to an application database (i.e. Microsoft calls this "forms authentication"). Because only a few Windows domain accounts are authorized to call this .Net webservice, the above code always uses the same username/password constants and it all works.
My question involves the newest webmethod added to the .Net webservice. It requires that callers must invoke it as a RESTful service which means it must be invoked by its URL. Here is a snippet of C# code that invokes it from an ASP.NET webclient:
            string r = txtRecordNumber.Text;
            string baseurl = "http://localhost/sdkTrimFileServiceASMX/FileService.asmx/DownloadFileCF?";
            StringBuilder url = new StringBuilder(baseurl);
            url.Append("trimURL="); url.Append(txtFakeURLParm.Text);
            url.Append("&");
            url.Append("TrimRecordNumber="); url.Append(txtRecordNumber.Text);
            Response.Redirect(url.ToString());
I assume a ColdFusion script could easily build a full URL as above with appended querystring parameters and redirect. Is there some way for the CF code redirecting to a RESTful webservice (by way of its URL) to set the Username and Password to this Windows account mentioned above? When the DownloadFileCF webmethod is hit it must be with the credentials of this special Windows domain account. Can that be set by ColdFusion someway to mimic the result of the SOAP technique (the first snippet above).
I hope my question is clear and someone can help me make suggestions to my ColdFusion colleagues. Thanks.

Can you clarify what you mean by "establish a different Windows identity"? Usually passing identity to a web site or service means adding something to the request's HTTP headers. This could be a cookie in the case of .NET forms authentication or the "Authorization" header in the case of basic authentication.
The SOAP web service invocation code you posted does use basic authentication, according to the CF docs "ColdFusion inserts the user name/password string in the authorization request header as a base64 binary encoded string, with a colon separating the user name and password. This method of passing the user name/password is compatible with the HTTP basic authentication mechanism used by web servers."
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec13a13 -7fe0.html
If you need to mimic the SOAP techinque you should have basic authentication enabled for your REST service endpoints.
If your authentication method is different then CF developers will need to add the appropriate HTTP headers to their service calls. Note that calling a REST service from CF would probably be accomplished using the CFHTTP tag if the service is designed to be consumed by the CF server.

Invalid request when calling REST-webservice with UTL_HTTP.

Always check the access_log and error_log files of the Apache web server in such a case. This will identify whether the error comes from Apache itself, mod_plsql, the Apex run-time engine, or the Oracle database.
I see that you're creating a HTTP/1.1 in PL/SQL - however, the web server response indicates a HTTP/1.0 call was received. Unusual. And could be part of the problem.

Restful webservice call hangs during service call

I have requirement where i need to call webservice from my code which is external service opened up.
I am using Spring RestTemplate for calling external service.
ResponseEntity<ResponseObject> responseEntity = rest
.exchange(URI, HttpMethod.POST, entityObj,
ResponseObject.class);
entityObj carries my request Object which is been marshalled.
when i have my request object(XML) limited to 2o elements my external service receives the request object then processs it and send out the response, if number of request elements exceeds 20 then external service is not receiving any request. mean while my server hangs out and seems to be waiting for response. I dont know where i am going wrong. I am using weblogic server for posting http request.
Note :-
I tested using my Junit where i posted 40 elements and it was successful.. the problem happen when i deploy into weblogic server. server might be blocking the data for some reason ..
I really appreciate response.

Issue was due to Https post and weblogic was getting timeout for some reason if data exceeds certain limit. so i decided to go with Http which solve the issue. looking into why weblogic getting timeout when using https; will udpate if i fix with https.
I was using default key store when using https post, does it cause issue?

Report data ( value ... tag) missing in the Webi report retrieved through RestFul Webservice

I am trying the below URL to get the WEBi report from SAP BO using the Rest Webservice support that is now available.
http://{serverIP:serverPort}/biprws/raylight/v1/documents/{documentId}
I am able to get the report but as I compare the same report response when using SAOP Webservice, there seems to be a mismatch in the response. Here is what I see in the SOAP response:
</td><td c="1" ><cell ref="1.E.4t" bid="14" h="26" w="231" pad="6,7" sid="-10"><ct >Some arbitrary value</ct><value type="xs:string">Some arbitrary value</value></cell>
But when I run it through REST, I am missing the <value ..> tag:
</td><td c="1" ><cell ref="1.E.4t" bid="14" h="26" w="231" pad="6,7" bt="1" sid="-10"><ct >Some arbitrary value</ct></cell>
Apart from this right at the start of the xml response, I see some property mismatch as well.
SOAP has this property extra:
<property name="output.format.xml.valuemode">yes</property>
While REST has these property extra:
<property name="output.format.xml.option.style">1</property>
<property name="output.format.xml.styledict.fontplatform">html</property>
<property name="output.format.xml.td.bandinfo">yes</property>
<property name="source.selected">data</property>
<property name="xelement.xml.object">yes</property>
<property name="xelement.xml.object.usemap">yes</property>
<property name="xelement.xml.object.usersupportedformat">image/png</property>
I am not sure if:
the <value ...> tag miss is because of these missing/extra properties or
current REST support has some issues
For my application the value tag is a must and I can't do without this, but with REST it seems no way to obtain that.
Any help or pointer(s) in this regard is appreciated!

Hello Milind,
According to our Product Owner Sam Polichouk, the solution should be available for you in 4.1 SP3, which is currently scheduled for release by the end of March 2014 (subject to change). The product team recommends that you get the raw, unformatted data values from within the Dataset specific call. This data contains a type to tell the end user what kind of data it is, so you can format it or use it properly.
The updated documentation for the SDK will be available at SAP BusinessObjects Business Intelligence platform 4.1 – SAP Help Portal Page once the Support Pack is publicly released.

Making a REST webservice call. Error code: 401 Access to the requested resource is not allowed

Hi All,
I’m having a hard time figuring out how to make Rest WebService calls.
I tried executing this directly through browser and I get an error.
http:localhost:8080/rest/bean/atg/userprofiling/ProfileServices/loginUser?arg1=[email protected]&arg2=Password

From the documentation I understand that I need to create a session, is the session only necessary to access secured components since this
particular method “ProfileServices.loginUser “ has been declared as not secure in restSecurityConfiguration.xml
Also, are there two different ways in which I can log in
1. Using RestSession.createSession providing the username and password.
2. Or using ProfileServices.loginUser or ProfileFormHandler
Can someone please clarify

If you are invoking the REST web-service from a Java client then you can create a RestSession object using the createSession method. But in your case you seem to be invoking it with a HTTP request which by default would be treated as a GET request by ATG's REST implementation. Therefore being a GET, it would try to fetch a property "loginUser" from /atg/userprofiling/ProfileServices component (based on your URL) which would always fail.
To invoke loginUser() method of ProfileServices with your passed argument you need to tell ATG's REST system to treat your incoming request not as GET but as a POST request which you can do using atg-rest-http-method control parameter in your request like this
http:localhost:8080/rest/bean/atg/userprofiling/ProfileServices/loginUser?arg1=[email protected]&arg2=Password&atg-rest-http-method=POST
It should work this way provided your restSecurityConfiguration.xml is proper.

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.
