Calling a web service from BPM without using bridge S/A

Hi Experts,
I want to call a web service from a BPM and I want to call it asyncronously. That is by having my request and my response as a separate interface.
I already did it by calling another BPM, this one with a bridge, but I don't like this solution.
Any ideas?
Regards
Gonzalo

Hi Sanjeev,
EDIT: I was wrong, I have to reconsider your scenario.
Leela,
Watch this:
http://img74.imageshack.us/img74/3536/presentacin2vm9.jpg
The points of my scenario:
-There's a BPM
-Send and Receive in BPM have to be asynchronous
-It have to comunicate with a WS wich is synchronous
-I thought that, may be, playing with the receiver SOAP adapter modules I will achieve to send the response to another SOAP adapter, a sender one, and then have my ASYNC/SINC scenario as it's described here: File - RFC - File without a BPM - Possible from SP 19.

REST web service using PL/SQL

Hello,
I am trying to learn how a REST web service can be created using PL/SQL and how it can be used.
I am using this as a starting point.
Also, I am using the pre-build "Oracle Developer Days" setup for this (which means I have 11.2 version of oracle database installed).
I have done all the steps mentioned in the above blog post but when I try to access the web service in browser, I get the
"404 Not found - The requested URL /devtest/rest-demo/departments was not found on this server" message.
Here is my DAD setup :
SQL> declare
l_name dbms_epg.varchar2_table;
l_value dbms_epg.varchar2_table;
begin
DBMS_EPG.GET_ALL_DAD_ATTRIBUTES (dad_name => 'devtest', attr_names => l_name, attr_values => l_value);
for i in l_name.first..l_name.last
loop
    dbms_output.put_line(l_name(i)||' => '||l_value(i));
end loop;
end;
2    3    4    5    6    7    8    9   10   11 database-username => HR1
path-alias => rest-demo
path-alias-procedure => rest_handler.handle_requestI have created the package and procedures as mentioned in that blog post
SQL> desc hr1.rest_handler
PROCEDURE HANDLE_REQUEST
Argument Name                  Type                    In/Out Default?
P_PATH                         VARCHAR2                INHave I missed something ?
Any help will be appreciated.
Thanks

Probably an security issue, I guess. The article (http://ora-00001.blogspot.com/2009/07/creating-rest-web-service-with-plsql.html) mentioned is a very good one (if not only I like what the site has become in recent years - much good tips and articles). As an alternative for your problems, have a look at the explaination of how Tim Hall has done it...

Protecting a REST web service with Policy Agent

I have deployed a REST web service in Glassfish using Jersey Annotations. A UI in the same Glassfish instance is protected by a policy agent that forces users through a login page. I would like to protect the REST web service with BASIC Authentication using the same policy agent. Is this possible? Is there supporting documentation?

Hi Daniel,
When you publish a message through Rest, hope your Restful service will receive/process the posted message?
So
YourBizTalk -->(Post Message to)-->RestFulService
From the error message, "the published message could not be routed because no subscribers were found.", it seems like the this Restful service is a
wrapper (or service interface) for BizTalk at client end( where message has been posted thru Rest) and actual posted message is “processed” by BizTalk and the error "" is from BizTalk "after" Rest. This message says the message you posted
through rest is not found subscription at their end.
So
YourBizTalk -->(Post Message to)-->RestFulService -->Clients'BizTalk.
Here problem is at Clients'BizTalk as shown where the posted message to their BizTalk is not processed because no subscription has been found.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

REST Web Service Output Parameter not working in POST Handler

I've created a RESTful Web Service in Oracle Apex, using a POST method as "handler". I've setup 11 input parameters which all work fine, it is my one output parameter that does not return successfully.
Here is detail on the Output Paramter
Name: returns
Bind Variable Name: :returns
Access Method: OUT
Source Type: Response
Parameter Type: String
The actual source is a call to a pl/sql package that returns a value that I set :returns equal to (eg :returns := v_result). I've tried this with Source Type Header and still the same result, 'no output'.
I see APEX is calling wwv_flow_api.create_restful_param to generate the parameters (for importing), is there any documentation on this procedure?
How can I get this output parameter to return something in the response?
The request accepts a Json payload.
Any help greatly appreciated
Thanks,
James

Solved my own problem :returns does not work needs to be returns

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).

Composite Application with RESTful Web Services

Hello!
Is it possible to build Composite Application with RESTful Web Services only. I use Glassfishe 2.1 and OpenESB 2.1.
Can you point me on some tutorials on the net to read about using RESTful Web Services in BPEL?

Hi Gabriel,
Let me try to answer some of your questions:
1) The "Requires Secure Access" attribute of a resource handler controls whether this handler must be accessed/consumed only over SSL (HTTPS). Oracle Database Cloud Schema Service is only offered over SSL, so this attribute does not have any effect on RESTful services deployed in this environment (because secure access is always required and there is no other way). That said, if you want to access such web service from your own APEX instance, your instance must have Oracle Wallet configured with appropriate SSL certificate.
2) The URI parameters are not required. If your web service returns data for many entities (for example, list of employees in employees/), you may not need a parameter. If your web service returns data for one specific entity (for example, details of one employee in employees/{id}), you may want to identify that entity with a URI parameter.
3) You can have many URI parameters, for example: customers/{id}/orders/{order_id}.
4) Yes, these are the same HTTP methods/verbs you would use from PHP.
5) If you are trying this POST example from your own APEX instance (not Oracle Database Cloud Schema Service) and you are trying to access a web service over SSL, then it is likely that the Oracle Wallet used by your instance does not include the required SSL certificate(s), or the Oracle Wallet is not configured at all.
6) I recommend to check RESTful Web Services for the Oracle Database Cloud white paper and Oracle REST Data Services Developers Guide. Oracle REST Data Services is the technology that enables RESTful services in the Oracle Database Cloud Schema Service.
You can certainly create your own web services in the Oracle Database Cloud Schema Service and consume them from the same environment.

Problem consuming Web Service from ECC 6.0 using dual certificates

Hi, I am trying to consume a secure web service on ECC 6.0 - so far without much luck.
When I try to connect to the ws server, it seems there are three certificates in action: a CICS certificate for establishing the SSL connection, a 'root' certificate from the PKI certificate issuer, and a private certificate issued by the above issuer (please forgive me if a have the syntax wrong - certificates are not my primary line of work). So, using Trust Manager (STRUST), I have created a PSE named 'OES' and imported all three certificates into it.
In SOAMANAGER I have set up the end-point using the WSDL-file and set the following parameters:
- Authentication Method = X.509 Client Certificate
- Trustworthiness Method = Holder of Key
- Issuer = <issuer from the root certificate>
- Name of Attester = <blank>
- Validity of SAML Assertion = 180
- Caching of SAML Assertions = False
- Attester System Destination = <blank>
- Name of Attester = <blank>
- User = SRxxxWS
- Password = <blank>
- Client PSE = OES
When I try to consume the web service, I can see in the log files that the CICS certificat is used for establishing the SSL connection but all I receive back is an HTTP 403 "Client Authentication Error". If I remove the CICS certificate from the PSE, the connection is not made.
How do I make the client certificate available for the connection? Have I approached the problem from the wrong side? Has anybody experienced something similar? Any help will be highly appreciated.
Thanks,
Bo

Hi,
I am not Certificate expert either but you can get plenty of help from "Security" forum on SDN. I can help you bit with some related SAP notes and forum answers:
See following notes :

Hi Mahesh,
One you are missing is authentication token or credentials.

Is it possible to add a user using the RESTful Web Services SDK

Others have asked before about user management features in the RESTful Web Services SDK. However I can find no answers or links which provide an answer to the question 'Is it possible to add a user using the BI 4.1 SP2 RESTful Web Services SDK'?
Any help would be appreciated.
Regards,
Steve

Hi Steve
Unfortunately, not possible. The BI RESTful can only get "stuff" that is already there. I suppose this would fall under some sort of "Object Creation" API and that is not there. Yet. Rumors abound, but nothing firm. Just as a BTW.; the Business Intelligence platform RESTful Web Service Developer Guide 4.1 is here:

Can we use REST web service as Data source in SSRS? !!!!NOT SOAP!!!!

Hello,
We have requirement to use the REST web service as the Data source of SSRS. Tried with XML as Data Source, but unfortunately I could not succeed because the query expects SOAPAction which is not available in REST Service.
Do we have any option to use REST Service, if so please provide some basic example, so that I can try out some options.
If not, do we have any alternate solutions to handle these situations?
Thanks!
Vinay

Hi Vinay.
After looking on it for some time, I am afraid currently there is no document to talk on how to use the REST web service as a data source.
You can use the link
http://technet.microsoft.com/en-US/library/aa964129(v=SQL.90).aspx for a renference.
From a support perspective currently this is really beyond what we can do here in the forums. If you cannot determine your answer here or on your own, consider opening a
support case with us. Visit this link to see the various support options that are available to better meet your needs: http://support.microsoft.com/default.aspx?id=fh;en-us;offerprophone

How to call Jive Search methods using REST Web Services from ADF

Hi
Can someone provide me an example to call JIVE Search using REST web services from Webcenter ADF.
As we have the similar facility to call UCM Search from WebServices DataControl.
Do we have anything similar like this for JIVE Search?
JIVE 5.1 is deprecating SOAP style web services and so I am planning to use REST.
Any suggestions on this is much appreciated.
Many Thanks
Khad

so what exactly is the problem here?
what is not working?

Report Repointing using RESTful Web Services

With respect to this link: Changing Dataproviders for a Webi Report using RESTful Web Services
Cosider the following scenario:
You have an automation code using which, you accepts 20 report id and their respective Current universe id and New universe id.
If suppose, you have user input prompts in 10 reports and you don't know those 10 reports, how will you provide values to those prompts at a single execution of the code?
OR
Is there any function using which you can provide associated random value to those prompts?

Hi Raghunath,
Looking at your macro, most of the functionality would be available with REST SDK. With BI 4.x REST is now only SDK which provides APIs to work with webi report. With .NET or Java SDK we could not eeven schedule a webi doc with prompts.
With BI 4.1 REST APIs include.
refresh report, schedule report, save report, export which is done by your macro.
For detailed tasks, such as saving and modifying the report for specific users and send to schedule, you would need to play around with REST Urls to understand the workflow.
For starters take a look at the devleopers guide for REST here:
http://help.sap.com/businessobject/product_guides/sbo41/en/sbo41_webi_restful_ws_en.pdf
Here is the doc which compares the availability of SDK APIs with different BI versions.
http://scn.sap.com/docs/DOC-53285
For any Enterprise level tasks, you could always use .NET or Java enterprise SDk and comibe it with your REST app.

Hello REST web service example deployment fails when using EJB

I was able to successfully deploy the hello REST web service example. But when I attempted to lookup an EJB via the following code I get an error message.
try {
ic = new InitialContext();
DirectoryBean db = (DirectoryBean)ic.lookup("java:comp/env/ejb/DirectoryBean");
} catch (NamingException ex) {
ex.printStackTrace();
Here is the error message in the NetBeans console window:
Deploying application in domain failed; Error loading deployment descriptors for module [hello] -- com.sun.enterprise.deployment.annotation.context.WebBundleContext cannot be cast to com.sun.enterprise.deployment.annotation.context.EjbContextat com.sun.enterprise.deployment.annotation.AnnotationInfo@15f1fa0
D:\java\Sun\swdp-tutorial-1.0\examples\rest\hello\nbproject\build-impl.xml:450: Deployment error:

I think the problem may be that the SimpleServlet example uses an apt feature to generate a web.xml which will replace any web.xml you already have in the project (and lose any references etc you might have in it). To work around this problem first copy the necessary lines from the web.xml in the generates .war file - they should look something like this:
<servlet>
<servlet-name>RESTBeans Application</servlet-name>
<servlet-class>com.sun.ws.rest.impl.container.servlet.ServletAdaptor</servlet-class>
<init-param>
<param-name>resourcebean</param-name>
<param-value>com.sun.ws.rest.samples.servlet.resources.RESTBeansResources</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>RESTBeans Application</servlet-name>
<url-pattern>/restbean/*</url-pattern>
</servlet-mapping>
Add these to your project web.xml, replacing any lines that look similar (the web.xml in the sample project has these lines that you'll need to replace:
<servlet>
<servlet-name>ServletAdaptor</servlet-name>
<servlet-class>com.sun.ws.rest.impl.servlet.ServletAdaptor</servlet-class>
<init-param>
<param-name>resources</param-name>
<param-value>test1</param-value>
</init-param>
</servlet>
<servlet-mapping>

<servlet-name>ServletAdaptor</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
Now you need to turn off automatic web.xml generation by adding <option key="noservlet"/> to the apt task option in build.xml (look for the apt child of the -pre-compile task in build.xml).
Clean and rebuild and make sure that the web.xml in the generated .war file now matches the project web.xml file.

Thin-client uses a RESTful Web Service

Hello everyone!
Once I've develop a few web services, it's time to "consume" them. I'm trying to develop a thin-client in JAVA (with the netbeans ide) but I haven't found the best way to do it.
So, which is the best way to create a LabVIEW RESTful webservice?
Obviously, JAVA is an option, how about create a client with another VI?
Greetings!
Francisco José Gómez López
Software Engineer

1) Are you trying to create a RESTful web service in LabVIEW?
or
2) Are you wondering about creating a thin client to consume the web service?
A1) Web Services in LabVIEW
A2) LabVIEW WebUI Builder You can create a VI to act as a client for your web services, but not a thin client (i.e. running in the browser)
