Oracle service bus and composing two web services

All,
Do let me know your thoughts on this.
Currently we have two web services
Web Service 1 - Verify Eligibility
Web Service 2 - Approve Proposal
Web Service 1 has one operation and accepts a well defined set of input parameters similarly web service 2 also exposes a single operation and accepts a set of input parameters.
These are deployed and running in our environment.
Now we have a requirement to stitch together these two web services and expose them as one single composite web service on the Oracle Service Bus 11g.
I want to create a proxy service on the OSB as unified web service (having its own WSDL) by composing the operations and input plus output parameters of the aforementioned two web services.
This way we can publish the WSDL to the front-end apps and they will trigger it with the required parameters and the proxy service will orchestrate the call to WS1 and WS2 and send the final output back to the calling client.
I was able to create an outbound call from the Proxy service to the underlying business services but I am not able to expose the Proxy service as web service with a WSDL i.e. create the proxy service by choosing operations of Web service 1 and web service 2
Please let me know your thoughts on this.

Sushant

Thanks Atheek
The proxy service I tried to create orchestrate 2 web services.
But where we are struggling is How can i make this proxy service (composite) as a web service along with the WSDL.
The proxy service should be able to accept calls from the client with set of inputs representing both the underlying web services and coordinate calls b/w these two services and return consolidated output back to the calling client.
I am not finding a way to create a proxy service (web service along with the wsdl) which is representative of the underlying web services in a consolidated manner that can accepts inputs on behalf of both the underlying web services, orchestrate calls b/w the 2 web services and return the final output back to the calling client.
example modified to keep it brief
web service1
operation name: Verify Eligibility
Input: Complex type (String name, int Id, String address)
Output: Complex type(String approval status, int Id, String reason)
web service2
operation name: Approve Proposal
input: Complex type(String approval status, int Id, String reason, int Amount, int EmployeeCount)
Output: Complex type (String final status, String recommendation)
Composite Proxy Web Service
name: Composite Eligibility and Approval
Input: Complex type ( String name, int Id, String address, int Amount, int EmployeeCount)
Output: Complex type(String approval status, int Id, String reason,String final status, String recommendation)
The composite proxy should be created in a manner to jam the inputs of both the underlying web services and expose a representative interface on behalf of both the web services. This composite web service interface creation (WSDL) is where we are struggling a bit.
Because the calling clients need a unified WSDL to able to communicate with the composite web service.
Do post your thoughts.
Thanks Again,
Sushant

How to control transactions (WS-AT) between two web services in OSB?

Could someone tell me if the OSB can have 2 diferents web services controlled by an unique transaction?
For instance: in the OSB there are two wsdl, each one with its own Business Service and ProxyService respectively. In my vb.net aplication I started a transaction, called the first web service succefully and from the second web service I got an exception. I expected the first web service undo its work because the vb.net aplication excute a rollback command. Is this possible? How can I do? Any sample or tip will be helpfull.
If I was developing without OSB, I would rely on WS-AT as shown in http://www.codeproject.com/Articles/38793/6-Steps-to-Enable-Transactions-in-WCF for two web services dot net, or for one web service dot net and other java, http://www.ibm.com/developerworks/websphere/library/techarticles/0707_lo/0707_lo.html.
My question is basically: Is still possible to keep a single transaction between multiple web services when they are mediated by OSB? If so, is there a example showing how?

Hi,
When you create the proxy server, you have to check "Transaction required" box on Message Handling page...

Apex 4.1 Form and Report on Web Service Report displays nothing

Hello I created and tested a webservice using the test feature in Apex 4.1.
I know the results is a string of 1 row.
I created a Form and Report on Web Service. When I run the form there is nothing displayed in the Reports section its just blank.
If I run the sql from the results region I get no data found.
Is the problem the returned data is not stored in the collection?
Edited by: Oracle Primavera on Oct 26, 2011 3:32 PM

What would be the reason for the following.
Testing the webservice in apex returns values.
However when I run Form and Report on Web Service Report if I query the collection it is always empty?
Does anyone have any experience on this issue? Is it a bug? Please some hints I have been trying for two weeks without success.

Two web services in a pdf form

I m designing a process which has two web services (adobe livecycle workbench) I can get respond from each of them but that means I have two xmls.
The problem starts from here .I need one document put into pdf however I have two Documents, one from each web service
ı just need to equal two xml to one xml that case I can have one document to put into renderPDFfrom process
what should I do ?
should I put another process to combine xml or is there any methods to combine xml
I m waiting for your answers
thanks for helping

thank you very much Jasmin your answer is brilliant but in my case When I put "Main" between Node1 and mainxml (not really "Main" in my case form1) it doesnt work correctly /process_data/mainxml/Main/Node1/Child
this is my code and also another problem
/process_data/wstranslatesum/Page1/tablo1   =      /process_data/wsresponse2/Envelope/Body/HelloWorldResponse/HelloWorldResult/diffgram/NewD ataSet
/process_data/wstranslatesum/Page2/Sonuc    = /process_data/wsresponse/Envelope/Body/getMaxWaitingProcessStepsResponse/getMaxWaitingPro cessStepsResult/diffgram/NewDataSet
when I use above example only
/process_data/wstranslatesum/Page2/Sonuc    = /process_data/wsresponse/Envelope/Body/getMaxWaitingProcessStepsResponse/getMaxWaitingPro cessStepsResult/diffgram/NewDataSet
above part works   they are on the other page
when I use the below
/process_data/wstranslatesum/Page2/tablo1   =      /process_data/wsresponse2/Envelope/Body/HelloWorldResponse/HelloWorldResult/diffgram/NewD ataSet
/process_data/wstranslatesum/Page2/Sonuc    = /process_data/wsresponse/Envelope/Body/getMaxWaitingProcessStepsResponse/getMaxWaitingPro cessStepsResult/diffgram/NewDataSet
it works perfectly   (did you notice that they are on the same page)
so what is the problem I know you are Expert
can youy recommend any resource which has real case example
thank you so much

AquaLogic Service Bus and XQuery Mapper

Hi all,
I'm new about using AquaLogic Service Bus and XQuery Mapper. I'm using alsb250_wls920.
To understand better the details I've developed two very simple EJBs stateless related to a generic CarRental scenario.
The idea is the following:
- EJB1 exposes a method for retrieving available cars from company A
- EJB2 exposes a method for retrieving available cars from company B
The method signature is the same:
public CarVO[] getAvailableCars(Category category, Double price)
the only difference is about the CarVO definition where one exposes more attributes than the second one (and also the package is different).
The goal is designing a new proxy service called getAvailableCars that calls the two above services and returns a set including all available cars from both companies.
The returned CarVO is the sum of all attributes from two above CarVOs plus a string company attribute.
So in AquaLogic I've defined:
- a JAR resource for importing my CarRental.jar
- two BusinessService resources related to the two above getAvailableCars services (from company A & B), called getAVISAvailableCars & getHertzAvailableCars;
- I've exported the two WSDLs from the two above BusinessService resources directly from AquaLogic console;
- I've written manually the WSDL 'getAvailableCars' that I use in the next proxy service definition
- a getAvailableCars_1 proxy service resource
Before completing the proxy service definition, I've decided to use XQuery Mapper for defining my trasformations.
But I got some errors when I try to import the WSDLs.
For importing simply I've created a wsdl folder inside my project and copied into it the 3 WSDLs definitions.
Because there are errors in 2 of these WSDLs (getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl) when I create a XQuery Transformation, I'm not able to select any source schema.
But getHertzAvailableCars.wsdl, getAvisAvailableCars.wsdl have been generated directly from AquaLogic console and I don't understand why XQuery Mapper complains about them.
If needed I can post also the CarRental.zip eclipse prj (that contains the above two EJBs) and CarRentalAqualogicPrj.jar AquaLogic prj (passphrase is aqualogic).
I thank you in advance for any suggestion.
Regards
Patrizio

Failed to retrieve data from the database/invalid argument provided when employing link between two web services datasources

Post Author: vpost
CA Forum: Data Connectivity and SQL
I am trying to join information from two related web services within CR XI. I have successfully set up the web services as data sources have been able to get to the point where I get good data back. However, when I try to pull in certain fields, I get an error that says "Failed to retrieve data from the database/invalid argument provided". Here's the scenario:
The web services are structured as follows:Web Service 1 (Artist) has attributes of Artist Name and Date of Birth.Web Service 2 (CD) has attributes of CD Title and Release Date. Underneath each CD are songs, each of which have a Song Title and Artist Name.
I have defined both web services and defined a link between Artist.Artist Name and CD/Song.Artist Name. I am able to run a report with Song Title and Date of Birth that crosses web services. I am able to run another report with Song Title and CD Title that crosses the different levels in the second web service. However, if I add CD Title to the first report or Date of Birth to the second (both of which effectively force CR to employ the link between the two web services AND the CD/Song hierarchical structure in the second web service, I get the aforementioned error.
Any assistance understanding how multiple web services can be linked in this manner would be greatly appreciated.
Thanks in advance.

Not sure about your exact situation, but having similar problem with another application and have tracked down to security. Added user to group Domain Admin and it works fine. It appears to be accessing a subdirectory which it does not have permission to use and then times out and returns the "invalid....". Seems that once the query just over a certain size (and I'm not sure what triggers this) it needs to make use of temparory file disk, intead of ram.
I'm still trying to track down which temporary it's trying to uses - so if you have any ques.

How to create items and BOMs using web services

Hi All,
I need to create, change and read Items and BOMs through web services (using SOA Gateway, right). I found this one here: "Process Item (convenience wrapper version)" or "Process Item" within
Internal Name     EGO_ITEM_PUB
Type               PL/SQL
Product          Advanced Product Catalog
Status          Active
Business Entity     Catalog Item
Right now, I don't know how to use it. If somebody has a simple example to create a single item, this would be perfect! Which one would be the right one to read detailed information about an existing item?
The second object I need to maintain (create, change and read) is BOM. Which API can I use here?
btw: I use EBS 12.1.1 on windows.
Many thanks,
Konrad

Hi!
Thanks for your quick answer but unfortunately, I must admit that I'm an absolute beginner with Oracle and EBS and so things like:
Enable trace and generate the tkprof file or open the form using forms builder to get the name of the API used in thta screen.or
Please check e-trm site for your question do not help me to much :-(
Any other advice?

[OSB and OWSM] - External Web service stacks and frameworks

Hi everyone ! I'm starting to read about OSB and OWSM and I'm having some doubts. I've some developments of Web services with external Stacks like CXF, JBossWS, Metro and I'd like to ask some questions:
1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?
2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?
3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?
I suppose that if I ignore the JAX-WS stack from Weblogic and use an external framework (like CXF) I'll lose most of the application server administration capabilities since the Weblogic server won't be able to recognize the CXF stack as it does with its own.But, the main doubt I'm in is, since OSB and OWSM might be used with external providers I probably won't need to develop my web services using the Weblogic implementation (which my team does not yet know) since there will be no features of the OSB and OWSM which can only be used with the Weblogic's stack. I would like, please, to know your oppinions about these considerations. Sorry about the long post and possible errors (I just started learning).
Thank you!

Hi Lupan,
I can speak mostly to OWSM as my experience with OSB is small thus far.
+1- Will I be able to productively leverage all features of OSB and OWSM like creating a proxy service to add WS-* standards policies and features (WS-Security, for instance) even with these web services implemented in different stacks other than Weblogic's ?+
OWSM (10gR3) has two types of policy enforcement point (PEP) -- Gateway and Agent. The Gateway acts as a remote proxy and is neutral to the service implementation technology as long as it adheres to SOAP 1.1. In this regard you can use OWSM freely with CXF, MS implementations, etc. Agents run in-process with the service and thus have far greater restrictions on what service implementation frameworks and containers that are supported. There is some certification for AXIS 1.x running in OAS and Tomcat; but practically speaking, my recommendation for Agents is to only use within OAS 10gR3 where it is built in (and using OC4J Web Services through JAX-RPC).
OWSM 11gR1 initially supports only agent-style (in process) PEP and is built-in to Fusion Middleware and WLS. It is only for Fusion and WLS Web Service implementations.
OWSM is quite full-featured for WS-*.
+2- If it is possible, do these web services need to be deployed at the Weblogic server to enable the OWSM and OSB to work effectively ?+
"No" if using OWSM Gateway PEP. A qualified "Yes" if using OWSM Agent PEP.
+3- Even if it is possible to use the OSB and OWSM nicely with webservices developed at external stacks and deployed at other application servers is there any reason to quit using these external web service stacks in favor of Weblogic's (like features only enabled on OSB/OWSM when the services use the Weblogic stack) ?+
There is the manageability that you mention, but also there is the identity propagation scenario and tight security integration. Both OAS and WLS hosted services in the native stacks (JAX-RPC and JAX-WS) allow sophisticated and secure passing of identity in the request -- for instance, via SAML Assertions in the WS-Sec header -- and built-in capabilities to map the passed identity into the running service's Subject (i.e. enabling JAAS security etc.).
In my experience this type of identity propagation functionality has either been absent or less complete in other typical implementation frameworks not closely aligned with the container security mechanisms.
Hope this helps,
Todd

Please help Installed apex 4.1 on Oracle 11g Xe can't create web services

I went to Shared Components > Web Service references to create a web services reference using wsdl.
My webservices are local to my network.
I do not use proxy. Not using UDDI.
I enter my WSDL URL but error message is returned
The WSDL document was unretrievable because either the URL you supplied was invalid, your environment requires a valid proxy server address for HTTP requests and you have not defined one for this application, or a wallet needs to be configured for this instance of Application Express for HTTPS requests
All I see are
Amazon Web Services 3.0
Google API Beta
Q1. How can I register my wsdl url?
Q2. How were amazon and google registered?
Edited by: Oracle Primavera on Oct 4, 2011 5:29 PM

Ensure that you can ping the web services server.
Then check whether there is a valid/appropriate acl for the apex_040100 user;
select * from dba_network_acl_privileges where principal like 'APEX%';
Refer to Enable Network Services in Oracle Database 11g in the install manual.

How to get up and run a Web Services/RESTful functionality?

Hello there,
The DBAs just completed the upgrade for the APEX 4.2 in our organization. I was asked to work with APEX and build some application. This morning I was asked by my boss to take a look at getting the Web Services/RESTful API Functionality up and running. I am new to this environment. When I check the RESTful Services I found out the are no RESTful Services. What do I do to get this running? as a Developer, I do not have access to any schema or web services. How do I go about making this work? can any one point me to some blog or site that will help me make this work?

Hello,
You can consume Web-Services from APEX, but you can't produce. So first ask your boss which web-service you want to implement.
There are 2 types of web services in general, SOAP based and RESTful. APEX provides simplified API's to invoke both types web-service.
Identify web-service you want to TEST
Create ACL for APEX_XXXX schema to access web-service
Create ACL for Proxy Server as-well, if required
If web-service is SSL-enabled then configure wallet. See 17.7 Implementing Web Services
Use APEX API's to invoke Web-Services. See APEX_WEB_SERVICE
You can process XML response from Web-Service using Using XQuery with Oracle XML&nbsp;DB
If Web-Service returns JSON data either you can use PL/JSON | Free software downloads at SourceForge.net to process response, or you can process response at client side using jQuery

Hari

How to install and consume GroupWise Web Service (SOAP)

Hello! I'm Razvan, programmer from Romnia, and I am new to GroupWise development.
I am asking if anyone could help me with a C# Visual Studio 2010 example of how to install and consume GroupWise Web Service (SOAP).
The documentation from novell site didn't help me, i didn't understant much of it.
All I need is either a link to a documented GroupWise C# developer step-by-step tutorial, or some code examples.
Can you please show me some code examples in C# with:
1)loging in using a username and a password,
2)retrieving contact list,
3)retrieving appointment list,
4)sending a mail,
5)setting an appointment
I don't know how to use "groupwise.wsdl" and customise it so that it points to our GroupWise server.
Please, I really need this because I am working at a project right now which involves GroupWise integration.
I hope I haven't disturbed anyone with my simple question.
I know this might be a very simple question given the complexity of the other posts here, but that's why I really hope I will get an answer soon.
Thank you very much!

How can I authenticate and authorize with Web Service on ESB ?

Hello,
I want to authenticate and authorize client with Web Service published
by HTTP/SOAP BC.
Simply if it is an Web Service as J2EE application, I will use
Basic Authentication with JAX-RPC and Realm.
But I think that Web Service published by HTTP/SOAP BC is not belong
to J2EE Application. Threre is no place to describe security role mapping
(like web.xml).
JBI 1.0 the section "5.5.1.1.3 Normalized Message Properties" comments
JAAS Subject is given in the NM Properties. Really in this package
com.sun.jbi.internal.security.*
implements JAAS autentication and authorization (at JaasAuthenticator).
But I can't see how to configure my Service to use this.
