OSB -- Invoking an asynchronous BPEL process in Oracle Service Bus

Hi All,
Can any one let me know how to invoke the Asynchronous BPEL process in OSB.
Thanks in Advance,
Feroz Tasha.

Hey,
What i was trying to say was that when you export your OSB project to file system, you can edit the business service in a file editor(e.g notepad, editplus etc).
In that, instead of suppose 127.0.0.1 u can put a token say @@HOST_NAME@@ and for a port say 7001 as @@PORT_NUMBER@@.
Then an ant script can replace the values of above 2 tokens with apt values, create a jar out of it and deploy it on the server.
There are numerous ANT scripts and examples available online.
Hope this helps.

Error while invoking an asynchronous BPEL process

Hi ,
I am trying to call an asynchronous BPEL process through java client.
Following is the code which I got from SOA bpel samples present in the following location
<SOA_HOME>\bpel\samples\tutorials\102.InvokingProcesses\rmi\com\otn\samples\async
The code fails while registering the callback
String convId = GUIDGenerator.generateGUID();
nm.setProperty(NormalizedMessage.CONVERSATION_ID, convId);
deliveryService.post("HelloWorld", "initiate", nm);
// register the callback
watchdog.registerAsyncCallback(convId, testAsyncHandler,
locator.getDomainAuth());
The error says java.lang.NoClassDefFoundError: org/collaxa/thirdparty/json/JSONString
I tried to search for this in google. But it seems noone has got this error or maybe noone has used this at all.
Maybe I am missing some jar file, but I am unable locate that.
Can someone help me in this please.

Hi,
These sort of class not found errors come when you are running from a client which does not have all the jar files requried to invoke BPEL using the client API.
org/collaxa/thirdparty/json/JSONString is orabpel-thirdparty.jar.
The complete list of Jar files you would need in the classpath are:
ejb.jar ($ORACLE_HOME/home/lib)
oc4j-internal.jar ($ORACLE_HOME/home/lib)
optic.jar ($ORACLE_HOME/opmn/lib)
orabpel-common.jar ($ORACLE_HOME/bpel/lib)
orabpel-thirdparty.jar ($ORACLE_HOME/bpel/lib)
orabpel.jar ($ORACLE_HOME/bpel/lib)
Hope this helps,

Can we invoke a asynchronous BPEL process from synchronous and vice versa

Hi,
Can we invoke a BPEL asynchronous process from synchronous and vice versa. If so how to perform that.
thanks,
Vijay

Yes you can
sync -- calling --> Asyncc
Async -- calling --> syncc
Perfomance is no issue, depending on your requirements. Not the Syncprocesses are short-running processes, these will time-out after 30 seconds, if no answer is coming from the async process.

Invoking asynchronous BPEL process from java ui

Hi,
I am invoking an asynchronous BPEL process from java ui.
I read somewhere that i can obtain an instance handler uing the lookupInstance() method of class Locator using the conversation id provided by the class NormalizedMessage.
My code looks like this
// Connect to Oracle BPEL server
Locator locator = new Locator("default","bpel");
IDeliveryService deliveryService = (IDeliveryService)locator.lookupService(IDeliveryService.SERVICE_NAME );
// Construct a normalized message and send to Oracle BPEL Process Manager
NormalizedMessage nm = new NormalizedMessage();
nm.addPart("payload", xml);
// Initiate the BPEL process
deliveryService.post("MyLoanFlow", "initiate", nm);
//Obtain the instance handler
IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
But this is giving the error - can not find any instance with conversation id 'conversationId'.
Also, if i try to obtain a list of instance handles associated with a process , it does not contain the most recently created instance
IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
IInstanceHandle[] iHandler = ph.listInstances();
out.println(iHandler.length + "<br>");
if i invoke the process for the first time the output is 0.
can you please help me. it is urgent.

Hi Sudipto,
Regarding your second question,
deliveryService.post("MyLoanFlow", "initiate", nm);
IBPELProcessHandle ph = locator.lookupProcess("MyLoanFlow");
IInstanceHandle[] iHandler = ph.listInstances();
out.println(iHandler.length + "<br>");
---- returns 0 ---
This is because MyLoanFlow is an asynchronous process in your case. So the control is returned to your java block immediately after the request for a new instance is posted. And your second line of code(querying for the list of instances) is executed even before the instance is created on the server side. You can verify this in two ways:
1. try creating an instance of a synchronous process using IDeliveryService.request - this will always result in the increment since the current thread is blocked till the new instance is created.
2. for your case, you can try
Thread.currentThread().sleep(500); - just allow the server some time for completing the instance before you query it for the list of instances..
and wrt question 1,
//Obtain the instance handler
IInstanceHandle handle = locator.lookupInstance(NormalizedMessage.CONVERSATION_ID);
But this is giving the error - can not find any instance with conversation id 'conversationId'.
For setting the conversationId, you could do so by including the following inside your .bpel file
<bpelx:exec name="test-setConversationId" language="java" version="1.4">
<![CDATA[
setConversationId("conversationId");
]]>
</bpelx:exec>
The code:
IInstanceHandle ins = locator.lookupInstanceByConversationId(NormalizedMessage.CONVERSATION_ID);
should fetch you the required instance in this case.

Issue in invoking the BPEL process from Oracle using a SOAP Request

Hi,
We are facing an issue while invoking a deployed Bpel Process from Oracle Applications 11.5.10..
Using a concurrent program( Unix / Host program ) we are passing the input variables required for the Bpel process in the ProcessRequest tags and forming this as a SOAP message payload.
Then trying to invoke the deployed bpel process using the end point location using HTTP POST..but nothing is happening..
The bpel process is not getting invoked when i look at the Console and also checked for the Manual Recovery queue..it's not stuck there as well..
Have set the Transfer Time Out to 25 minutes using UTL_HTTP.SET_TRANSFER_TIMEOUT(1500);
Could someone please help us as soon as possible with this ..as this is critical and we are stuck at the moment.
The logic is mentioned below :

Resilience in oracle service bus

HI to all,
I'm getting a problem because i have have a process in oracle service bus, that have a split-join and when a OSB server is shutdown the split-join stop and when the server are started up it don't restart i can i have resilience to overcome this problem.
Best Regards

Hi,
Documentation states:
Split-Joins provide support for propagating transactions. Operations set with a QoS of Exactly Once are executed in the transaction. Operations set with a QoS of Best Effort do not execute in the context of a transaction.
Split-Joins do not handle transaction rollback in the case of exceptions. It is the responsibility service component that called the Split-Join to handle transaction exceptions and rollback.
The last statement is quite difficult to understand... I believe you need to handle a fail in the caller of the split join and possibly do a retry from there... The split join won't restart by itself...

Asynchronous BPEL Process

I am trying to understand better how I can use an asynchronous BPEL Process.
With the JDeveloper Wizard I can create a BPEL Process by using the Templey Asynchronous BPEL Process.
I can deploy the BPEL Process into an Weblogic Application Server.
To test the BPEL Process I use the Enterprise Manager 11g Fusion Middleware Control
http://localhost:7001/em/
I click on Test Web Service and the result is
The web service invocation was successful. However, there was no response to the invocation from the server.
I click on Launch Flow Trace
and I can see the callbackClient (Started invocation of operation "processResponse" on partner "bpelprocess_client")
I used the JDeveloper to create a Web Server Proxy. I mean the Wizard who creates a test client for the BPEL process.
I provided the WSDL Document URL and clicked on the next button. On the Dialog Specify Default Mapping Options the Option
Generate As Async is inactive. I expected that the Web Server Proxy Wizard should understand that the service contains
asynchronous features.
Currently I am not able to write a Java client which can receive the async Response from the BPEL Process.
Am I missing something? Can someone clarify to me what is need to receive the async Response from the BPEL Process?
Thank you very much
Regard
Michael

I am using JDeveloper 11g Release 1 (11.1.1.5.0)
SoaSuite 11.1.1.5.0
WebLogic Server Version: 10.3.5.0
Oracle Database 11g Release 11.2.0.1.0
I used the jdedeloper BPEL wizard to create a BPEL 2.0 Specification Asynchronous BPEL Process exposed as a SOAP service.
I deployed the BPEL Process witch JDeveloper to the WeblogicServer.
I created a new Generic Project.
The I used the jdeveloper Web Service Proxy wizard to create a java client.
I select JAX-WS Style and in the WSDL Document URL I typed
http://localhost:7001/soa-infra/services/default/WebServiceExample/bpelprocess_client_ep?WSDL
I found the URL http://localhost:7001/soa-infra/services/default/WebServiceExample/bpelprocess_client_ep?WSDL
from http://localhost:7001/em website.
In the dialog
Specify Default Mapping Options
I can type in Package Name , Root Package for Generated Typed and I can click on
Unwrap Wrapped Parameters. I can not click on Generate As Async.
Two dialogs later I can select
Generate asynchronous methods where specified by the JAX-WS binding
The Java classes are created without an error.
There is a class called BPELProcess_ptClient.java and in the main Method of the class there is a comment
// Add your code to call the desired methods.
I add there a line to invoke the method
bPELProcess.process("mystring");
That works but I do not get a response.
Am I missing something?

How to call a BPEL process from Oracle Apps Java Concurrent program

Hello,
I need to trigger a BPEL process from Oracle Apps. Can anybody tell me how to do that? I have two triggering option--
1. On button click from a Form 6i screen
2. Using Java Concurrent program.
Thanks in advance.
Debkanta

I am not sure how concurrent program works, but may be one of the way might work out, let me know if Java Concurrent Program works a bit different way
- [if async] Through concurrent program, you can insert message token to db or aq, and BPEL can be instantiated from there
or
- If it supports pure java call, then you can look at multiple documents (e.g. http://www.oracle.com/technology/products/ias/bpel/pdf/orabpel-Tutorial7-InvokingBPELProcesses.pdf) to invoke your process
- You can also use oracle db utility to invoke soap operation and get the result back

Unable to get callback from Asynchronous BPEL process to work (AXIS Client)

Hello,
I am calling an Asynchronous BPEL process from an AXIS client, and I am unable to get the callback functionality to work. The AXIS client code has been generated from WSDL2Java using the BPEL process' WSDL file.
I CAN insert an invoke node in the BPEL process and invoke my Callback web service using that, but obviously that means the BPEL process is limited to only responding to one pre-determined client, which won't work.
My questions:
- How does the BPEL process know what endpoint to use to make the callback?
- Do I need to modify the generated code to create a SOAP Envelope and invoke the process with the envelope, intead of the invokeOneWay call?
- If I do need to create a SOAP Envelope with a replyto element, what is the structure of a typical BPEL envelope? Is there an example somewhere?
I have looked at the examples in the interop directory, specifically the AXIS calling Async BPEL, but I would like to try to keep the client code as independent as possible (I don't really want to have a dependency on the OTN library).
Any help would be greatly appreciated!!
Thank you.
-Ryan

Please have a look at the Binding in the WSDL. Axis must provide the ReplyTo and
MessageId information there. As far as I see, this must be done by an Axis-Handler,
because the Binding-Part in not generated by WSDL2Java.
I was able to generate the JavaClasses by using the "WSDL2Java -a" option, but
I still do not see how to use them in a handler and how to register the handler.
Maybe someone can give me a hint.

How to get response from an asynchronous BPEL process in Java

I'm experimenting with BPEL and doesn't seem to be able to get response from an asynchronous BPEL process. Here's the deal:
I have a BPEL process that takes a string as input, and gives another string as output. This is a asyncronous process.
I want to initiate this BPEL process as a web service so I generate a Webservice Proxy in JDeveloper 10g (10.1.3.0.4). The function to call the process is now called "initiate" and takes three arguments: the input string, a "org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo" and a
"org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID".
HTTP-Analyzer shows that invoking the BPEL process with initiate("somestring", null, null) results in sending a SOAP message to the BPEL process, which returns a "202 Accepted". How do I get the response from the process? My intuition tells me that I have to use that second argument, that EnpointReferenceType thing. How do I use that?
Another question: If a asynchronous BPEL process does not exists (so the endpoint does not exist) the Java proxy does not throw an error when runned. It does not even sends a message. It exits with status 0! (This happens for example when deploying a new version of a process and when the "old" version is undeployed). Calling a non-existing synchronous BPEL process, the Java proxy DOES throw an error.

Clemens,
That all sounds logical. But somehow it is still a mystery for me ... Somehow I don't see what should be done.
To call the async BPEL process I have the following procedure:
initiate(String input, org.xmlsoap.schemas.ws._2003._03.addressing.EndpointReferenceType replyTo, org.xmlsoap.schemas.ws._2003._03.addressing.AttributedURI messageID)
The first argument is the input for my BPEL process. The second is the address to a webservice that should handle the callback, right? The third is a messageID (makes sense, but why of the type AttributedURI?).
Here lies my problem. It is not clear to me how these EndpointReferenceType & AttributedURI work. I can't find anything on the net about it. The AXIS examples as where mentioned earlier use other types (namely the "org.xmlsoap.schemas.ws.addressing.MessageID" and "org.xmlsoap.schemas.ws.addressing.ReplyTo") which are completely different.
What I did so far:
- I created an webservice proxy that listens on the onResult endpoint of the BPEL process.
- I created an webservice proxy that calls the BPEL process through the initiate procedure, but it is not completely clear to me how to construct the EndPointreferenceType replyTo, and the MessageID. I did something like this:
EndpointReferenceType replyTo = new EndpointReferenceType();
// callback service running on local machine
// This URI class is the java.net's version
URI replyToURI = new URI("http://vaccinatie:8988/syncro-callback-context-root/stringconcatCallbackBindingPort");
// This AttributedURI is the org.xmlsoap.schemas.ws._2003._03.addressing's version
AttributedURI address = new AttributedURI();
// the only public methos that made sense to me:
address.set_value(replyToURI);
replyTo.setAddress(address);
// call the BPEL process
myPort.initiate("test123", replyTo, address);
But the above doesn't work (largely because I don't know what I'm doing here prob.:-) ) It does send the "test123" message, and the BPEL process does process it, but I don't seem to get the callback right.
I hope this makes my problems somewhat clearer. I hope someone can help me, because I'm just a beginner in this whole "web service area" and seems to do something terribly wrong here, because it should be very simple. Thx.

Correlation in Asynchronous BPEL process

I have thoroughly read docs & various blogs for this correlation concept and I am developed the bpel process without any compilation error. But when I execute, all the instances are waiting in receive activity with message *"Waiting for "processResponse" from "AsynchBPELProcess3.AsynchBPELProcess1.PartnerLink1". Asynchronous callback."*
My scenario goes like this, I have three simple Asynchronous BPEL process with flow A --> B --> C i.e;
step 1) client invokes process A with initial inputs
step 2) process A does some assignment and invokes process B and then followed by a receive activity to receive response back directly from process C
step 3) process B simply invokes process C after some assign activity
step 4) process C do actual task for computation -- this is from where i am expecting output result at process A
Done correlation at process A's recieveInput activity & in additionally added a receive activity to get response.
Flows works as expected....everything if fine. But only at the time of returning the output result back to process A ..this waits for long time and after some time it becomes stale.
Thanks.

Yes you can achieve this. There are many ways to get this, it depends on your design. I didn't try the correlation sets.
If i were you I would like to use the message header properties of the JMS queue. Set an MsgID for the request message and use the same MsgId to listen the response. You have to ask the partner to listen to your request message and store the KsgID and set the same MsgID to the header properties in response message.
Let me know if you have any questions.
Thanks
Ramana.

Asynchronous BPEL Process called from an empty BPEL process getting lost.

Hi
I have an empty BPEL process calling an asynchronous BPEL process. The empty process is triggered by a read file activity. It finishes successfully and even calls the asynchronous process. There is no error thrown but the called asynchronous process does not show up in the dashboard.
When this asynchronous process is manually run from the console I get the page stating 'Cannot find the specified instance'.
I am using Jdev 10.1.3.2 and SOA Suit 10.1.3.1.
Any suggestion as to why this is happening and what is the remedy?
Buddhadev.

Check your log as soon as you find that the parent process has found its way into the console. More information on logging can be found here - http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28982/logging.htm
Not quite sure why its so, but since 10.1.3, I've observed that the console simply doesn't show errored processes at times. So, checking the log can be a starting point in diagnosing the real issue.

Implement callback for an asynchronous BPEL process through Java

Hi ,
I am trying to implement a callback functionality for an asynchronous BPEL process through java.
I found the code in the samples folder of SOA suite installation folder .
<SOA_HOME>\bpel\samples\tutorials\102.InvokingProcesses\rmi\com\otn\samples\async.
There is an AsyncInstanceWatchdog object which registers a callback object(in this case an object of AsyncCallbackImpl class) for a specific CONVERSATION_ID.
String convId = GUIDGenerator.generateGUID();
nm.setProperty(NormalizedMessage.CONVERSATION_ID, convId);
deliveryService.post(proc_name, "initiate", nm);
// register the callback
watchdog.registerAsyncCallback(convId, testAsyncHandler,
locator.getDomainAuth());
// start it
watchdog.start();
There is no problem till the last line. But once the BPEL process returns the control( does a callback), it throws the following error.
May 25, 2010 3:36:06 PM oracle.j2ee.rmi.RMIMessages EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER

System.out.println(XMLHelper.elementToString((Element)pResultMessage.get(key)));
public String getVariableName() {
return "output";
The variable name is same given in the sample code. And the BPEL process returns variable named output. So the name should not be a problem.
Is it because of the scope of the variable.. If so, how do I change it.
Any help would be appreciated.

Solved it by some googling .... :)
Here is the link:-

or
[http://beautifulwaste.blogspot.com/2008/04/calling-asynchronous-bpel-process.html]
Both gives the same solution..
In pre 10.1.3.3 release the default behaviour were to keep global variable information along with the instance information for completed BPEL processes.
In 10.1.3.3 or later, this behaviour changed for performance reasons so that the default behaviour is now, not to keep any global variables for a BPEL process once the BPEL process has completed.
You can configure this behaviour on a process level basis by using the parameter keepGlobalVariables in the bpel.xml file for the specific process:
<BPELSuitcase>
<BPELProcess src=".........." id="...........">
<configurations>
<property name="keepGlobalVariables">true</property>
</configurations>
</BPELProcess>
</BPELSuitcase>
