BPEL Callback issue in Asynchronous service

Hi,
I’m sporadically getting Callback service issue with Asynchronous BPEL service. (SOA version is 11.1.14)
Appreciate inputs to resolve it.
The service is working as expected in most cases and is able to make a callback to the parent service, but random few instances give error – “Unable to access endpoint”
<remoteFault xmlns="http://schemas.oracle.com/bpel/extension">
<part name="summary">
<summary>
oracle.fabric.common.FabricInvocationException: Unable to access the following endpoint(s): https://xxxxx.com:14002/soa-infra/services/default/POServices!1.0*soa_2c3cea4d-8791-453c-aed1-0569a86fa268/WorkFlowSvc%23POProcess/WorkFlowSvc
</summary>
The endpoint URI opens up in browser, so endpoint exists; and as mentioned above, many instances have completed successfully too.
The service continues to be in running state and hence the parent process also remains in running state, unlike in success case when both get completed..
Now, one observation is that the binding port and endpoint location given in code is http uri; not https
So not sure why the deployed service is pointing to https uri for callback to parent service.
In success cases, I’m not able to see the endpoint uri for callback, only the message is seen.
So I’m not able to confirm if it uses the same https uri when it completes successfully..
- Could the issue be related to https access/ owsm policy?
- How to check the endpoint point uri for async/ callback service in success case? The SOA logs don’t indicate it either, except in error cases (log level is development/ Trace32 fine)

Hi,
FabricInvocationException exception mostly occurs when process is trying to connect WS/Partnerlink service which is not accesible.
I fixed this issue,
1. After setting external WS certificate(Keystore) information in my weblogic server.
2. I have made my weblogic url as public, after which wsdl url is accessible to my destination service.
Hope this would help in fixing your issue.

Ajay

How to get the callback from an asynchronous BPEL?

Hi, I have deployed an asynchronous BPEL on Oracle Application Server as a Web Service. The BPEL is named CreditRatingBPEL. The input is a social security number (Ssn) and the output is a credit rating.
Now I have some troubles in consuming BPEL with Axis1.4. I have generated the client stubs by WSDL2Java tools. I have initiated the asynchronous BPEL successfully. Now I want to get the callback from the BPEL, but I don't know how to do it.Here are some Java snippets:
public static void main(String[] args) throws ServiceException, RemoteException {
// TODO Auto-generated method stub
CreditRatingBPEL_Service service = new CreditRatingBPEL_ServiceLocator();
CreditRatingBPEL_PortType requestPortType = service.getCreditRatingBPELPort();
CreditRatingBPELProcessRequest request = new CreditRatingBPELProcessRequest();
request.setSsn("31060931");
// asynchronous invoke
requestPortType.initiate(request);
// how can I get the callback from the web service?
I will be very appreciated if you can give me some suggestions. Best regards!

BPEL and Axis2 Asynchronous service

Does anybody have develope Oracle BPEL Asynchronous process and Axis2 Asynchronous service.
Can somebody share their expreince??
Thanks
Gopal

I have looked at BPELCallingAsyncAXIS sample it works fine with Axis 1.3, I was using this sample to start with Axis2.
But BPELCallingAsyncAXIS sample required otn-jaxrpc.jar libaray which implement ws-addressing and asynchronous service call to BPEL for Axis 1.3.
And otn-jaxrpc.jar library require all jaxrpc classes specific dependency.
I am not sure whether this library otn-jaxrpc.jar is production ready and how stable it is
Axis2 already have ws-addressing and asynchronous webservice implementation so I don't need to rely on otn-jaxrpc.jar
And I think for future webservice (document style) development we will be using axis2 b'cos of WS-* support , Asynchronous webservice
Thanks

How to make a Mediator deal with calling an external Asynchronous Service

Hi,
Using TP 4.
I want my Mediator to invoke an Asynchronous Service that is external to the composite application. But I do not know how to get the reply from that service back into my Mediator.
I have worked with the sample of calling an asynch BPEL component within the same composite - that is fairly easy to accomplish.
What how can I tell the external service to invoke a callback porttype on my Mediator. Can the SCA container work out the correlation between the external service and the correct instance of the SCA composite? Should the Mediator publish the callback interface as an external service at the SCA Composite level? If so - how would the correlation work? If not, how does it work?
Any suggestions - even the statement that I always need a BPEL component in between that will support correlation with external asynch services, if that is the case - will help.
Thanks.

Kylie, welcome to the discussion area!
Cable modems behave differently than DSL modems in that they will "remember" the last device that they have associated with. Your modem is "remembering" your MacBook and when you connect the TC, the modem won't connect because it "remembers" the MacBook.
You need to make the modem "forget" a previous device whenever you make a change in the device that is directly connected to the modem. Here's how:
Push the reset button on the modem if it's present
Pull the power cable on the modem
Pull the battery from the modem if it is easily accessible
Leave the modem powered down for 25-30 minutes
Power down the rest of your network as well
After the wait period, connect the modem to the WAN port on the TC with an ethernet cable
Power up the modem first and let it run for 3-4 minutes by itself
Then power up the TC the same way
Power up the rest of your network the same way
Depending on how you had your TC configured with the DSL modem previously, you may need to make a few changes in the settings.
Post back on your progress.

Unable to wire BPEL process to external Web Service

Hi ,
I am working on calling Web service from BPEL Process(I am trying to invoke currency converter service from BPEL process).I added Curreny Converter webservice component in "External references" Swimlane in SOA(Jdeveloper) composite editor by using WSDL that I got for that service..I also built the BPEL Process (BPEL Currency Process-which has bpelcurrenyprocess_client service in 'Exposed Services' swimlane).Then I wired BPEL Process to "CurrencyConverter" service.When U click on BPEL process,We have to get the that(Currency Converter" service) in right side partner link in BPEL Process( .bpel editor) editor.But I am not getting that in partner link.
I hope some of you guys are already worked on BPEL process which calls "CurrencyConverter" Service.Can anybody help me in this issue?
I am giving service details through which u can track about the issue that I am talking about:
WSDL : CurrencyConvertor.asmx.wsdl
example application is :bpel-106-CallingWebServices.jpr
Note : I want to siimulate above application in my application
Edited by: 899283 on May 14, 2012 4:48 AM

if you are not getting the partner link even after adding in the composite view, you may just perform the following steps.
Right click on the right swimlane in your BPEL View, create a partner link, and you would see 4 buttons just above the Text box for WSDL URL. Select the 3rd button there. That is the service wizard. Once you click on that, you would need to repeat the set of steps that you did on the "Composite View" earlier.
And there, you have it in your BPEL View!
Hope this helps!

Bpel callbacks(human task)

Hi,
i have a human task assigned to sequential list of users(2 users).On outcome updated by 1st user,i need to manipulate the task before it is routed to 2nd user.I thought the bpel callbacks would be helpful...but i could not..
By default,the onAssigned callback is called when 1st user updates the outcome and routed to 2nd user..But it is late when we want to manipulate the task in onAssigned callback,bcoz it is already been assigned...
OnTaskUpdated or OnTaskCompleted is not invoked..
...can anybody give some idea???

OWSM: BPEL callback bypasses Gateway and ServerAgent

Hi,
I have a BPEL Process A that asynchronously calls BPEL Process B. For securing the processes I use OWSM.
I have tried both a Gateway as well as a ServerAgent but in both cases the callback message from B back to A bypasses either Gateway or ServerAgent.
Whereas the requests for invoking both processes A and B do show up in the OWSM logs as expected.
The entire system works fine, with either Gateway and / or ServerAgent.
Perhaps some BPEL-internal-magic going on (e.g. for improving performance)?
What does it take to have the response from process B go through either the Gateway or the ServerAgent and be subject to the policy pipeline specified in there?
Thanks!

Hi Denis,
Thanks for your reply.
Although I have not solved the problem, I have some more insights to share. Questions remain though ...
In the SOAP message that follows HelloWorld3 calls HelloWorld2 asynchronously. WS-Addressing at work to correlate the callback to the original instance of the HelloWorld3 process.

Could the WS-Addressing information be used as a 'shortcut' for the callback to the HelloWorld3 process? Any way, the callback is not picked up by the ServerAgent ...
The processes finish as expected but the message traffic is not properly regulated and, hence, not subject to proper policy enforcement.
Any ideas?
Thanks, Sjoerd

I am having trouble connecting to my network all of a sudden. It is not an issue with the service/router. I keep getting kicked off and getting a ! in my airport... anyone know what's up with this?

I am having trouble connecting to my network all of a sudden. I am able to connect to other networks but not my own. It is not an issue with the service/router because other devices connect fine. I keep getting kicked off and getting a ! in my airport. Last time it happended I called apple and the suggested I wipe my HD and reinstall everything. I did and it did not work. One day I turned my laptop on and it connected no problem. Now it has kicked me off again. I tried resetting my IP address but that does not work either! Has anyone had this problem?

Try this:
Apple menu / System Preferences / Network.
Click Location: and select Edit Locations..
Click + (plus sign), and enter a name for the new location - anything will do.
Apply this.

Anyone else having issues with location services since the 7.1 update? Ever since I updated i've been seeing the location services on my status bar at all times.

Anyone else having issues with location services since the 7.1 update? Ever since I updated i’ve been seeing the location services icon on my status bar at all times. I noticed that google was the app that was using it a lot, but after I turned the feature off for google my phone started using the “traffic”, “frequent locations” and “cell network search”. When I turn the feature off for all of those things it’s no longer a problem. So just wondering if anyone else is having this issue or if anyone has a solution?

The "solution" is probably to increase your knowledge. You've done good things. Perhaps this article will educate you a bit more about location services.
Basically, they can be very useful, but can cause a lot of iPhone use. A major example is "Remind me to ... when I leave home."

Issuing material to Service order contractor and tracking it

Hi Experts,
We are creating service activity PR, PO, Service acceptance as per standard SAP. We would like to issue materials to this contractor on free of cost and he would return balance material, if any.
We can reserve material for this activity and goods issue against this reservation (using movement type 221). But this material will be consumed in project.
Is there any solution for this?
Regards,
RSVRMurthy.

Hi Murthy,
From the scenario explaination I believe you make a common procurement for the project and provide it to the service executed by various departments such Electrical Instrumentation etc.
In that case create a Procurement WBS element in your project structure along with the mechanical,electrical instrumentation WBS structure.Make all project related procurements under this procurement WBS element by attaching material through dummy Internal activities(as you cannot attach material directly to WBSE).
Your department WBS element will have all the subcontractor service activities.When you want issue the material to a particular subcontractor activity,make a stock transfer from Procurement WBS element to the WBS element to which the service activity is attached(in your case 1000 M).Till now it will be in the inventory.When the subcontractor provides you the actual consumption data, make a goods issue to that service activity(in your case 800M).
In this way you can track the
1)total procurement of cable
2)Cable lying with each subcontractor
3) actual cable consumption by subcontractor
4)actual material cost realising against the actual execution activity.
But there are some points to be noted,
Hope you will be following Project stock concept, with procurement type being Res+PR for WBS.In this case the reservation will be in the internal activity under with Material(Cable) is attached.That is in the procurement WBSE.So while closing the project you have to clear those open reservation.You have option for clearing open reservations while confirming.As I mentioned earlier the internal activities are dummy, you should have a control key with cost irrelevant.
One more point to note, while issuing the material to the service activity, you have to make a manual issue as there wont be any reservation against this service activity(that is you cannot adopt details of the reservation).

Hi,
>> I have some portal service and how to use that in the web dynpro application.
Yes. U can use Portal service in webdynpro. Check the link given by subathra.
>> and also what is the main diff between Portal Component and web dynpro application
Portal Components are components designed to run in portal server while webdynpro application can run in J2EE WebAS.
>> do we required portal to run web dynpro application.
No for general cases. Just WebAS is sufficient to run webdynpro appl. But if u use portal service in ur webdynpro appl, then make sure both (portal service and webdynpro appl) run on same J2EE engine. That is mandatory.

what is the problem? how come i can't initiate the process?
i will be happy if i could get help..
thanks in advance

can you initate the process from the bpel console successfully?
if so can you use obtunnel from the installation to trace the soap message (that goes over the wire), my best guess in this case is a problem with a header (holding the wsa information) ..
after starting obtunnel it will liesten to a custom port, and will forward the request to the engine, so you need to point your client to this new port..
