Binding RESTful web service / being exposed to a RESTful web service

Hi , I have two quick questions
1. can ORACLE BPEL bind a RESTful web service?
2. can a BPEL process be exposed to a RESTful web service?
Thanks

Bumping back to the top of the list.
Has anyone got any experience with RESTful web services saving to an item vs. a collection? Any pointers are greatly appreciated.

Issue with services being published in SR

Hi Experts,
We have an issue with services being published in SR
1. Service is created and published from ECC to Service registry
2. End points are created in Soa manager
But the service state is shown as u2018Modelledu2019 instead of u2018Configured u2019 in SR
Thanks,
Sowmya.

Hi Sowmya,
If you want it to appear in the SR as 'Configured', change your procedure to as follows:
- Create Service in ECC
- Configure endpoints in SOAMANAGER
- Then Publish Endpoint binding URL (as it appears in SOAMANAGER) in SR. You can do this Publishing in SOAMANAGER as well. The idea to configure the endpoint before publishing to get the 'Configured' state.
Some additional reading:

Exposing RFC as a Web Service

Hello All,
I am working on a SOAP to SOAP (Backend as ECC where I am exposing an RFC as Web Service). Once the Web service is generated for RFC and the WSDL is imported in PI, I can see that all the fields in different nodes become mandatory.
Is it how normally Web Service for BAPI works or can this behaviour (mandatory / optional) be controlled ?
Also when I execute the end to end scenario via SOAP UI, I don't get any error back but also neither get the Return table nor the Sales Order NO. I am using the BAPI BAPI_SALESORDER_CREATEFROMDAT2.
Can it be because of no COMMIT (The BAPI uses external commit although this reason seems less likely as executing a RFC wo any commit atleast gives me a Sales Order no) ?
How can this call be analysed in backend ECC system ? (As I assume that messages will not be visible in SXMB_MONI as explained by the Harald's thread below. I am currently in process of getting authorization of SOAMANAGER logs but wondering how it'll help?
Thanking you in advance.

Hi,
Please see the SOAP ststud..
http://<host>:5<sys#>00/mdt/amtServlet
also you might check any error logs.
The error is because of invalid xml document. So check the validity of the xml message ie. after first mapping i.e Req mapping.
For this you can refer this -

How to update the Query of an existing WEBI document's dataprovider, through the RESTful Web service SDK.

Hi,
I am trying to update the Query of an existing WEBI document's dataprovider, through the RESTful Web service SDK.
For this, first i will get the Dataprovider information,
Example:
URI: http://localhost:6405/biprws/raylight/v1/documents/11111/dataproviders/DP0
Expected result;
<dataprovider>
     <id>DP0</id>
     <name>Query 1</name>
     <dataSourceId>1234</dataSourceId>
     <updated>2014-04-18T11:55:21.000-08:00</updated>
     <duration>1</duration>
     <isPartial>false</isPartial>
     <rowCount>113</rowCount>
     <flowCount>11</flowCount>
     <dictionary>
          <expression qualification="Dimension" dataType="String">
               <id>DP0.DO1</id>
                <name>EmpID</name>
               <description>Employee ID.</description>
                <dataSourceObjectId>DS0.DO1</dataSourceObjectId>
          </expression>
          <expression qualification="Dimension" dataType="String">
               <id>DP0.DO2</id>
               <name>EmpName</name>
               <description>Employee Name.</description>
               <dataSourceObjectId>DS0.DO2</dataSourceObjectId>
          </expression>
     </dictionary>
     <query>SELECT Employee.EmpID, Employee.EmpName FROM Employee</query>
</dataprovider>
Then Changing the above dataprovider's Query to some thing like below,
<query>SELECT Employee.EmpID, Employee.EmpName FROM Employee where Upper(Employee.EmpName)='RAJ'</query>
Please let me know the RESTful Call required to do this.
Thanks in advance.
Thanks,
Mahendra.

FYI, the output of this call returns something like:

Benefits of exposing function module as web services

Hi All,
We are developing a case study about exposing function modules as web services.
Those web services would be later used for integration to SAP box with a Java application.
Kindly help me with the pros and cons of exposing function modules as web services when compared to SAP PI. Also please do quote some examples, wherever possible.
Thanks,
Varun

Hi Varun,
Pros--->
1)Exposing FM as Web Services is indeed a good choice when you want service consumer to be platform and language independent.
i.e it can be consumed by .Net, java or any other language.
2) You are moving towards SOA
3) Composing Business Process by concatenating different functional modules is easy.
4) Complexity is less while consuming services Java, CAF etc.
Cons----> Performance for Web Services is comparatively less than JCo .
If you are bringing PI in between landscape, you are increasing one more layer of middleware which would also hit performance.
The benefit which PI can give is monitoring your company wide integrations at one central point when you have huge systems.
Hope this helps.

Exposing EJB interfaces as Web Service

Hi all,
I created a prototype using EJBs and Web Services and found out that JDeveloper only allows to expose as Web
Services the Remote interfaces of EJBs and not the Local ones.
Assuming I have included Local and Remote interfaces for each of my EJBs exposed, my questions is, after deploying the application on OC4J 10g are the Web Services accessing the EJBs through the Local interface (I assume it should) but then why I am only allowed to expose the Remote one as Web Service?
TIA,
Best Regards,
Giovanni

Hi,
no, inbound interfaces can only call web services
that are exposed on some other web servers
only outobund XI interfaces can be exposed as web services
(in this case XI acts as a web server)
and other applicaitons can call this outbound interface

michal

Exposing Inbound Interfaces as Web Service

Hi,
when it comes to expose XI interfaces as web services, the XI documentation quotes:
"Sie können sowohl von Outbound- als auch von Inbound-Message-Interfaces WSDL-Beschreibungen erzeugen."
-> i.e. Inbound interfaces can be exposed as web services.
But the web service definition wizard expects the quotation of an outbound interface. So am I right when I say that I always need an outbound interface? If yes, why is it possible to expose inbound interfaces???
Cheers,
Heiko

Exposing a process as web service on Oracle BPM 11g

Hi!
Does somebody know how can I expose a process as a web service on Oracle BPM 11g? How does it works?
In the version 10.3, when we exposed a process as web service it always had 3 default methods: startSession, getInstanceStatus and discardSession, is it the same in the 11g version?
Where can I found some info about it? Any tutorial?
Thanks a lot!
Ana

Typically you would use a Message Start event to start the process in conjunction with a Message End event. This will allow your process to be called as an asynchronous web service.
In the "Implementation" section for the start event, you specify the input parameters. You can specify "Define Interface" to directly define the interface, or use an existing interface from the BPM Catalog (the From Catalog option).
For further details on the different event types and their use cases, refer to the modeling and implementation guide:
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15176/toc.htm
You can test the web service and examine the WSDL and endpoints by using FMW control (Enterprise Manager). In the menu on the left hand side: expand SOA -> SOA-Infra -> <Partition Name> -> Composite Name, then click the "Test" button at the top.

Exposing a Form-Driven Web Application within a Portlet

Hi All,
I'm having a bit of a problem exposing a form-driven Web-Application within a portlet window.
The web-application I'm working with utilizes the Oracle XSQL servlet and is basically a collection of .XSQL pages which are formatted using .XSL stylesheets that produce output HTML for the client.
The application contains hyperlinks for navigation, but is largely Form driven.
The application has already been deployed into an Oracle Application Server 10g container as a J2EE object(.ear file), and is fully functional and accessible over the web.
In order to expose this application thru a Portlet window I utilized the Url-based provider services that come with the Oracle PDK. This allowed me to set up a simple URL-based provider for the site without any coding whatsoever. I also included inline rendering declarations to force the application response to be rendered within the Portlet window.
This setup works fine when only hyperlinks are used to navigate thru the application, however, Forms do not appear to work with this setup. Everytime a form is submitted, the data is posted to the Portlet which fails to pass it thru to the underlying web application. Instead the Action="somepage.xsql" parameter is appended to the URL of the Portal itself thus returning a "page not found",etc... error.
After much OTN searching I have found that the PDK 10.1.2 URL services package does not support Forms for inline rendering. Thus this solution comes close but falls short of what I need.
I was wondering if anyone can point me to a solution that would:
1) allow me to display the entire web application within a Portlet window (app only outputs HTML & some client-side javascript, but takes POST requests to the XSQL Servlet)
2) without modifying it's current Form-driven interface, or any of the application's underlying code for that matter,
3) and without having to resort to java coding the Portlet interface.
The URL-Based Provider setup is almost perfect, I just need to find a way to allow forms to pass thru to the underlying application so that it's response can be rendered correctly.
Current Setup:
Oracle Application Server (Portal & Wireless) 10.1.2g
J2EE with OC4J_containers.
Oracle XSQL Servlet (ver 10)
Windows 2000 OS

I tried that, the default "Base URL" provides the "Display Option" attribute but only gives me these 2 options:
- Full browse window link
- New browser window link
I have also tried other items that use "Base URL" (Simple URL, UrlItem, URL) and are all the same thing. The only items I could find (relevant to this need) and provide the option "Item displayed in page area" were:
- "Page link" item
- "External Application" portlet
I even created a fresh Instant Portal to recreate the defaults and add the URL item again, but nothing :(

Do you know what are the other´s needed data?
Thanks!

I am able to test the business service i exposed as webservice without using BPEL .
i sent some dummy values to the processId, processVersion , etc.
Only required value is payload     @ * name NCName once i provided the correct value to it i received the correct response by executing the business rules.
Thanks

Web Service Proxy client to invoke a Web service on SSL (Jdev 10.1.3.1)

Hi,
I have to develope a Web Service proxy client to invoke a web service on SSL. First I'm testing with OC4J 10.1.3.1 and JDEV 10.1.3.1 and did this:
1) Developed a basic PL/SQL Web Service with JDEV and publish on my standalone OC4J.
2) Made a test with a browser, it worked OK
3) Generated a proxy client from JDev 10.1.3.1 to invoke web service, it worked OK
--- Now make it work on SSL----
4) Then, added SSL configuration to oc4j , generated a certificate with keytool (updated server.xml, secure-web-site.xml), and shutting down and starting the OC4j instance.
5) Import the certificate to JAVA_HOME/jre/lib/security/cacerts
6) Test web service from browser on https and worked OK.
7) When tried to modified proxy client (generated in step 3) to make it work on SSL, I realized that just changing the END_POINT to the new url (https) it worked!
Questions----
1.- By default the proxy client generated from JDEV 10.1.3.1 knows how to deal with SSL conections?
2.- If I dont have previously the server certificate to import it into JAVA keystore (cacerts) how could I ,from proxy client code, capture it and import it before the validation occurs... because if the certificate is not in keystore , the program fails.
Thanks in advance
J.

Hi,
Could you please provide me with the steps necessary to create a web service proxy client through JDeveloper or any other mechanism when 2 way SSL (requiring client authentication) is enabled.
Thanks a lot in advance
