WSDL for getDataExport Restful Web Service

Hello Folks,
As per documentation http://help.sap.com/saphelp_sop301/sop301_api_en.pdf
API uses RESTful WS getDataExport from 3.0 onwards..
I am trying to call this WS from ECC. How I can get its WSDL file.
Since URIs mentioned in file seems not working.
Please suggest.

A related question: can one expose a servlet as web service (Document style). How to do that?

Which is the best API for creating restful web services.

Hi guys,
I have tried a lot of apis to create a restful web service. But none of them has perfect documentation or examples. Which is the best one that has good support and future.

"Best" automatically implies opinions and speculation; one I personally believe has a bright future is Jersey. Jersey is the reference implementation (RI) for [JSR-311|http://jcp.org/en/jsr/detail?id=311] ("The Java API for RESTful Web Services" or JAX-RS).

Need to auto-generate SDK for REST web service.

My company has developed a REST API for some web services, and we'd like to provide users with a Java SDK for consuming those services.
Our services are described by an XSD schema. On the backend, we are using JAXB to create Java classes corresponding to the schema. We create the request objects based on the parameters in the REST url, and JAXB converts our response objects from Java to XML.
We'd like to provide our users with similar Java classes on the client side. They should be able to create the object corresponding to the request, fill in various parameters, and submit it to our web service. The SDK should automatically convert the object into a REST URL, hit the URL with a Get, read the XML response, and convert that response into Java objects.
It seems like we should be able to auto-generate such an SDK based on our schema.
It seems like there are several tools for doing this for SOAP web services. For example, Apache Axis has Java2WSDL and WSDL2Java.
Can anyone recommend tools for creating client-side libraries for consuming RESTful web services? Does anyone have advice on products to avoid?

Replying to my own post here. The WADL2Java project on java.dev seems to be more like what I need. The only user-experience I've seen on the 'net is in this forum post:
http://forum.java.sun.com/thread.jspa?threadID=5239123&tstart=0
Anyone else used it?

Use Xmlspy or some editor to modify or edit the WSDL as per need.
elementFormDefault="qualified"
This means that all the elements in the XML document must have namespace variable prefixed with them.
elementFromDefault="unqualified"
This means that not all the elements in the XML document requires namespace variable prefixed with them. Only the root element has to be prefixed with namespace variable.

Restful Web Services - First Party Authentication with custom authentication schemes

Hi
I've successfully enabled security using first party authentication on our Restful web services however these only work with the built in Apex accounts and not other authentication schemes.
Ideally I'd like to authenticate against LDAP, however when I enable this authentication scheme the restful services don't work as they only support the Apex accounts.
Has anyone implemented LDAP authentication for Apex restful web services, either directly or using Glassfish ? Does anyone know if support for custom authentication schemes on the feature roadmap for a future Listener release ?
I attempted to configure the glassfish application against LDAP but am still working on it.. glassfish never challenged the client to authenticate (it's only to be for the web service endpoints and nothing else), so any pointers on how to set that up for Apex would be appreciated.
Thanks
Kes

Hi Gemma,
unfortunately at the moment you are caught between a rock and a hard place:
- As you point out there is no way in APEX for a user to self-register themselves, short of developing your own table to store users and configuring APEX custom auth to authenticate against that table
- Listener can only authenticate against the the APEX user repository, it cannot integrate with custom APEX authentication.
There may be other options though, by leveraging the authentication capabilities in the JRE and/or WebLogic/GlassFish application servers. We're interested in addressing this use case, so if you wish to investigate further please send me an email ( colm <dot> divilly <at> oracle <dot> com).
Thanks,
Colm Divilly

How to call restful web services from BPEL

How do we call create partnerlinks for calling RESTful web services in Oracle BPEL.
Any ideas ?

Raymond,
1. To consume WebService in Flex you don't need FDS at all.
2. AFAIK, you need crossdomain.xml at WS host or System.allowDomain("ws-host") or System.allowInsecureDomain("ws-host") on Flex side. Check Flex documentation.
3. Better to discuss this topic in some other forum -- say WebAS General. It's not related to WD

Creating RESTful Web Service for BLOB retrieval

Hi,
Just got RESTful web services working in Apex 4.2.1 with new Listener 2.1.
I have now been asked to create a RESTful web service by which photos in BLOB column can be retrieved upon providing the ID for that photo. Can this be done using the Creating RESTful Service Module of Apex 4.2.1? Looking at the Apex 4.2 documentation, I would assume this can be done, but has anyone used this with BLOB data?
Thanks,
Pat

Hi Pat,
Yes this can be done using RESTful Services - you just need to ensure the query used is in the required format. To obtain a BLOB for a given ID, you would need create a Resource template and handler with the following settings:
Resource Template Settings:
URI template: emppic/{id}
Resource Handler Settings:
Source query: select mimetype, product_image from demo_product_info where product_id = :id..where the format of the SQL query is SELECT 'content_type', blob_column FROM . . ., as mentioned in Rick Greenwald's Cloud White paper "RESTful Web Services for the Oracle Database Cloud", under the "SQL Source Type" section (see www.oracle.com/technetwork/database/database-cloud/public/restful-wp-1844130.pdf ):
where 'content_type' is a string passed to the browser to be used to identify the incoming data, and the column to identify the source of the data being sent back. This data is sent back untouched by the Oracle Database Cloud Service. The Media Resource Source Type is typically used for media objects, such as images, where the data will be directly handled by the recipient making the call.The MIMETYPE column in the sample query above holds the necessary setting for the 'content_type' i.e. 'image/jpeg'. The value of ID is then passed in as a parameter when calling the service e.g. emppic/1234. The item level help text would be more helpful if it included additional information, and this is something we intend on addressing in a future release.
I hope this example helps.

Hilary

ADF Mobile - Securing REST Web Services

Hi,
I've developed some REST web services for my ADF Mobile app to use. They work fine but I'm having trouble securing them. According to the developer guide:
http://docs.oracle.com/cd/E35521_01/doc.111230/e24475/amxwebservices.htm#CHDGFCGD
10.5.2 How to Enable Access to REST-Based Web Services
Since only one security policy is supported for REST-based web services, ADF Mobile automatically adds oracle/wss_http_token_over_ssl_client_policy for REST web service over HTTPS, or oracle/wss_http_token_client_policy for REST web service over HTTP protocol to enable Oracle Web Services Manager (OWSM) Lite Mobile ADF Application Agent to inject a proper security header.
..so I'm trying to attach the policy oracle/wss_http_token_service_policy to the web service, but deploying it to Weblogic results in the below stack trace.
I'm trying to attach the policy in JDeveloper by selecting the service class in the java structure pane, then in the Property Inspector, using the "Web Services extension" section to select the policy.
I'm guessing I've missed a step, but can't find what. Or I'm doing completely the wrong thing. Either way, any help in resolving would be very much appreciated.
Rich.

Basic auth with RESTful WEb service and Web Service reference

Hi, All,
We have made much progress on getting an application working wtih RESTful web services but now are trying to figure out how to lock down a RESTful Web service while making it available for a particular application.
We are using one of the sample 'emp' table web services that come with Apex 4.2 and are trying to apply Basic Auth to the WEb Service via Weblogic filter defined in the web.xml file. That works fine. I now get challenged when I try to go to :
https://wlogic.edu/apex/bnr/ace/hr/empinfo/
And when I authenticate to that challenge I am able to get the data. (we are usiing LDAP authentication at the Weblogic level)
However, I am not sure how to get same basic authentication to work with the Web Service reference in my application. I see the error message in the application when I try to call that Web Service:
401--Unauthorized<
And I see:
"The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.46) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials"
How do I provide the credentials in the Web REference or do I provide credentials in the Application?
Web service works fine if I remove the RESTful web service basic auth from the Web.xml file.
Should we NOT use Weblogic basic auth and instead use basic auth from Workspace RESTful web service definition. If so, how do we implement THAT basic auth in the Web Service definition and in the Web SErvice Reference on the application?
Thanks,
Pat

How to bind to REST web services?

The REST web services don't provide WSDL. How to bind this kind of services?
Thanks.

Melvin, not yet (in fact it's on my plate) - what I usually argue for is to abstract these pieces into services (much like what I did in the rest sample, and then expose them .. )
In any case - I will start collecting ideas (that is topics) for best practices soon .. Let me know if you have any specific wishes.
cheers

HTTP error when trying to access RESTful web service from application

Hi,
We are getting the following error when trying to access a RESTful web service coming from Apex workspace 4.2.1 and Apex listener 2.1:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29024: Certificate validation failure
In the Debug report, besides the above I also see:
error_backtrace: ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 543 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 1164 ORA-06512: at "APEX_040200.WWV_FLOW_PROCESS", line 396
We get that error whether we use https or http in the URI pointing to the web service. When I test the Web Service in Workspace RESTful service GUI, I get the data back. When I go build an application with a report calling the RESTful Web Service I get that error. Both the Application and the Workspace RESTful services are on the same Apex environment and even the same workspace.
What is odd is that I can actually put the URL of the web service into a browser and I get the data: (using the demo hr data in sample RESTful services.)
IN browser-- https://weblogic-dev.edu/apex/ace/hr/empinfo/
yields:

Any ideas on what would be causing the Error above in our application?
Thanks,
Pat
Edited by: patfmnd on Mar 11, 2013 3:25 PM
In reviewing the above error, I think we are realizing that we have to have the Weblogic layer SSL cert (actually the CERT from our BigIP load balancer which also does our SSL termination) imported into the Oracle server wallet where Apex is installed. Am I correct?
PM

We resolved our problem. The Apex Administrative Guide made us realize that we had to set up Wallet path in the Instance. This required working with DBAs to follow the Advanced networking guide to get the wallet set up on our server. We then added that path to the Instance configuration. (Manager Instance --> Instance settings). We ran into another other issue related to our implementation of CAS but were able to resolve that, and 'voila' were able to get the sample RESTful service consumed by our application!!
Now to the task of figuring out how to get Basic Auth working between client application and RESTful web service. If anyone has that working, let us know!!
It would be helpful if in the documentation of the Apex 2.x listener or Apex install/configuration there was clear reference to the above steps required for HTTPS access to RESTful web services.

401 Unauthorized Error When calling a SharePoint REST web service from SharePoint 2013 Workflow

We have our Workflow Manger installed on the same server as our SharePoint 2013 WFE development environment. When creating a SharePoint 2013 Workflow all Calls to a SharePoint 2013 REST web service results in a 401 Unauthorized error.
As an example I created a simple workflow that should return a JSON result. The REST Url returns the results in the browser without error.
Set Variable:webServiceUrl to https://<hostnamedsitecollection>/_vti_bin/client.svc/web/lists/getbytitle('ISR%20Approvers')/Items?$select=Title&$filter=Title%20eq%20%27General%27
then Build{...} Dictionary (Output to Variable:requestHeaders)
then Call [%Variable:webServiceUrl%] HTTP web service with request (ResponseContent to Variable:responseContent |ResponseHeaders to responseHeaders | ResponseStatusCode to Variable:responseCode)
The RequestHeader is set to the requestHeaders variable though the web service call properties
then Log Variable:responseCode to the workflow history list
After manually running the workflow in SharePoint on a list item in the ISR Approvers list it Logs "Unauthorized" in the Workflow History Log. It does this with every SharePoint REST web service call that I have tried through the workflow.
It doesn't have anything to do with the Workflow Manger being installed on the same machine as the SharePoint WFE does it?
Thank You for any insight

Hi,
According to your post, my understanding is that you had 401 Unauthorized Error when calling a SharePoint REST web service from SharePoint 2013 Workflow.
Please make sure you use the ‘Call HTTP Web Service’ correctly.
You can enter the URL into the brower to check whether it is correctly.
You need to
create the Request header requestHeaders
using a Dictionary:
Accept : application/json;odata=verbose
Content-Type : application/json;odata=verbose
To associate the
requestHeaders variable, select the Call action
property, set the RequestHeaders property to
requestHeaders.
Please refer to the following articles:
Working with Web Services in SharePoint 2013 Workflows using SharePoint Designer 2013
Calling the SharePoint 2013 Rest API from a SharePoint Designer
Workflow
In addtion, you need to make sure you install the workflow manager correctly.

Issue with Calling Rest Web Service using Designer workflow

Hello all
I am calling a Rest web service- HTTP Post (yammer API)-
http://www.yammer.com/api/v1/messages.json?data-app-id=myappid&group_id=groupid&body=MyPost in yammer using sharepoint 2013 designer workflow.(My Requirement is to create a yammer post when I approve an item in sharepoint).
but my header parameters are creating issue while executing workflow.
Currently I have these many parameters configured in request header
Accept -application/json; odata=verbose
Content Type -application/json; odata=verbose
content length header -255
Is there anything wrong or I need to additionally pass some values in call web service action?
Any help would be highly appreciated

Hi Mahesh,
