Polling from jms OSB/BPEL

They are different orders coming to a queue, which are not in proper sequence (Ex: order no : 5 is coming first, order no :3 is coming next and order no :1 is coming at last)
These need to picked from a queue to OSB/BPEL, where we need to sequence the flow, (Ex : order no : 1,2,3,4,5).
please let me know how to implement above requirement in BPEL and OSB.

Only solution I could see is to move them in DB and sort them.
U can choose the messages using message selector but can't sort them

Debatching is possible when we are reading messages from JMS queue

Hi all,
If i place a message in a queue can i read the message from JMS using BPEL ( JMS Adapter ) or OSB( JMS Transport ) like batcth rather than reading the whole message in to the OSB or BPEL at the same time .
is this option is available in OSB/BPEL ??
Thanks

Jms adapter not polling messages from jms topic

Hi
We have a jms adapter configured in BPEL process which need to poll messages from JMS topic.Unfortunately its not polling message from JMS Topic if we add Message Selector and Durable Subscriber properties in jca file.Please find jca file content below
<adapter-config name="SyncCustomerPartyListCDHJMSConsumer" adapter="JMS Adapter" wsdlLocation="oramds:/apps/AIAMetaData/AIAComponents/ApplicationConnectorServiceLibrary/CDH/V1/ProviderABCS/SyncCustomerPartyListCDHProvABCSImpl.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/jms/aia/syncCustomerParty_cf" UIJmsProvider="WLSJMS" UIConnectionName="Dev"/>
<endpoint-activation portType="Consume_Message_ptt" operation="Consume_Message">
    <activation-spec className="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec">
      
      <property name="PayloadType" value="TextMessage"/>
      
      <property name="UseMessageListener" value="true"/>
      <property name="DestinationName" value="jms/aia/Topic.jms.COMMON.CustomerParty.PUBLISH"/>
    </activation-spec>
</endpoint-activation>
</adapter-config>
If we remove Durable subscriber and message selector properties,its able to poll messages.
Any pointer will help
thanks in advance
Baji

After changing below property in jca file.JMS adapter is able to poll messages from JMS Topic.
<property name="UseMessageListener" value="false"/>
But if i un comment below line and deploy my code again, it stop pulling the messages from topic.
<property name="DurableSubscriber" value="XYZ"/>
If i bounce the server after above change and deployment ,it will start polling the message.I am not sure why i need to restart my server after adding above property.
Thanks

Polling from the database view in BPEL 11g

Hi,
We do have a requirement of polling from the database view in BPEL 11g. I am exploring the following polling strategies in our case:
- Delete
- Logical Delete
In case of Delete polling strategy, can we delete the record as the view does not allow deletion. In this case, do we have any other way to achieve this functionality?
In case of Logical Delete, We have to mark the status column with particular value. how could we achieve the same when the view is not updateable.
In 10g, we can override the delete polling strategy with an update statement. Is it possible in 11g?
Thanks & Regards

Hi,
I am also doing the same thing what you have done, please help me.

Concurrent nodes reading from JMS topic (cluster environment)

Hi.
Need some help on this:
Concurrent nodes reading from JMS topic (cluster environment)
Thanks
Denis

After some thinking, I noted the following:
1 - It's correct that only one node subscribes to a topic at a time. Otherwise, the same message would be processed by the nodes many times.
2 - In order to solve the load balancing problem, I think that the Topic should be changed by a Queue. This way, each BPEL process from the node would poll for a message, and as soon as the message arrives, only one BPEL node gets the message and take if off the Queue.
The legacy JMS provider I mentioned in the post above is actually the Retek Integration Bus (RIB). I'm integrating Retek apps with E-Business Suite.
I'll try to configure the RIB to provide both a Topic (for the existing application consumers) and a Queue (an exclusive channel for BPEL)
Do you guys have already tried to do an integration like this??
Thanks
Denis

Polling a JMS Queue

Hi,
I am new to ODI,my scenario is that I want to poll a JMS Queue, from ODI for messages, and once I receive the message I want to persist it in DB, I need help to make this work.
Thanks,
Rahul

I think you ran into a known Bug that has been fixed in recent versions/service-packs (sorry, I don't know the version number). Setting the delivery mode override to Persistent is fine as a work-around as long as you're sure that your applications don't send non-persistent messages to the affected destinations. If this is a concern and you need to force the delivery mode override back to its default whilst still keeping your time-to-live override, I think you can probably do this by shutting down your domain, then editing your XML to remove the delivery mode override stanza, and finally restarting...

JMS BC & BPEL Transaction Scope

Hi,
I'm trying to use Open ESB with BPEL SE JMS BC and HTTP BC to create a store and forward layer in a integration architecture. The idea is that messages that are used to update a slow external system (or one that is often down) are put in a JMS queue and then the JMS BC picks them up and passes them to a BPEL process via NMR. The BPEL process then calls the external system. If the external system is down, or some other system related error occurs, then I want the transaction to roll back andthe message remain on the queue to be retried later.
My issue is that when the JMS BC picks up the message, it sends it to BPEL via NMR and as soon as it gets the "Done" response, it commits the associated XA transaction and the message is permanently off the JMS queue. But the "done" response is sent by the BPEL SE as soon as it gets the message, as opposed to only once it has called the external system successfully. This breaks the model as any failures are not retried... Is there a way around this? Am I doing something wrong? How can I get the transaction context to span the entire call flow from JMS BC to BPEL and back with failures resulting in the message remaining in the JMS queue to be retried later
Thanks
Paul

Paul,
The reason for the current behavior of BPEL SE (sending DONE as soon as reeve completes) is by design to support asynchronous message communications and long running processes. We do not want to keep the transaction open for the life of process instance as the transaction may timeout (for long running processes). If you want to override this behavior you can do so by setting the Business Process as Atomic (Atomic attribute of business process as true), but the effect of this would be that all the operations in bpel engine and also outbound invocations would use the same (received) transaction context. Note that some of these features are still under development. I understand that this still might not solve your use case where the best solution would be reties. This work is underway and should be available in next release.
Just to give you heads up; retry support is being provided as part of Systemic Qualities initiative which is underway and is targeted to provide support like wire qualities (throttling/reties), fault and security propagation among others across open-esb components. The particular solution to you interest would be wire quality initiative. Once implemented this would allow configurable number of reties a specified intervals.

Malkit

OSB/BPEL Develper needed in Guangzhou China

If you have 2 or 3 years of experience in OSB / BPEL, pls contact me by QQ744032069, in or wanna travel to Guangzhou.

Use BPEL: WSDL operations having multipart in messages
For this recommendation what is the reasoning behind? And is there a way to get around it in ESB?
I am creating a pass through routing service for an already created client service that has multiple parts for the input and output. I have found a workaround in jdeveloper for being able to create the service by starting jdev using :Start jdeveloper.exe -J"-Dpreview_mode=true" which indicates that you cannot transform any of the values- which is fine for my services for now, but now I am finding that my routing service is only passing through the first part of the input message and I am getting the following error:
The message Returned from the call is returned as HTML as an Error 500-Internal Service Error
Error Message:
oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException: An unhandled exception has been thrown in the ESB system. The exception reported is: "oracle.tip.esb.server.common.exceptions.BusinessEventRetriableException: An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke: serialization error: java.lang.ClassCastException: oracle.xml.parser.v2.XMLElement
I can see the payload that is being passed to the SOAP Service is only the first part of the message.
Any suggestions workarounds?

Issues in invoking a web service from a JAVA/BPEL client...

We are trying to invoke a web service from a JAVA/BPEL client using org.apache.soap classes. But everytime we are running into issues of IllegalAccessError or InvalidClassError or IncompatibleClassError based on different jars we are trying to include in our project. Attached is a simple BPEL project which tries to invoke a web service through JAVA embedding (no supporting jars need to be included explicitly). It erros with following trace:

Could you please help us out or provide any pointers. Any help would be highly appreciated

Because you weren't told what to get, perhaps you already have it eh?
What you want to read up about is JAX-WS, which is the webservice API bundled by default with your JDK (Java 6 and up). You'll find the wsimport tool in the bin directory of your JDK. I recommend you explore that directory and read up about all the executables you can find there, to be more prepared in the future. Know the tools you work with and all that. Most tools have a manual on this website:
http://www.oracle.com/technetwork/java/javase/tech/index.html
(under tools and utilities). Not wsimport, that is part of the jax-ws documentation. Better you look for jax-ws tutorials using Google, it will be quicker.

How to control File read Proxy Service when it is polling from folder?

Hello all,
In my current requirement we are receiving xml's through one folder(LOCAL) from source side.we are picking those xml's by proxy service PS1 as file transport for every 10 sec and configured that folder path.In PS1 message flow we put on routing action to one bussiness service,that business service sending those xml's to one MQ.
We already created this interface but the issue is source side they plan to change that folder and also they want to stop this service(folder to MQ) sometimes based on synarios.That folder will be delete or if exist proxy wont read messages from that folder.
But proxy is still looking for that folder in Test ENV on Unix system then it gives error beacuse of unix folder structure is different,proxy unable to create that folder in unix system.it is creating in windows.
Now we want to control that service when the folder is ready that time only proxy will activate otherwise not..i.e like if condition "if cndtion is satisfied PS1 starts the polling from that folder else condition should be work.
How can i control PS1 service?
Is there any chance to control by using another proxy?
Experts please guide me..
regards
venu

Hi Terry,
According to your description, my understanding is that you don’t want the yollow bar notification to display when you open Access documents.
This issue seems to be about the client application. Please compare the followings with the things that you did:
1.Open the documents
2.Click File->Options->Trust Center->Trust Center Settings
3.Click Protected View, unselect ‘Enable Protected View for originating from the Internet’
4.Click Message Bar, select ‘Never show information about blocked content’
5.Click Macro Settings, select ‘Disable all macros without notification’
In addition, as this issue is about Office, I commend you create a new thread in Office forum, more experts will assist you with this issue.

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.

Error in Accessing AQ Anydata queue containing LCRs from JMS

Hello,
I tried to access Anydata queue containing LCRs (captured by oracle stream capture process) configured in Oracle 10g 10.2.0.3.0 from JMS.
I am getting following error:
oracle.jms.AQjmsException: JMS-225: Invalid JDBC driver - OCI driver must be used for this operation
SQL Code that I used configure in Oracle Streams

//wait for a message to show up in the queue
ObjectMessage message = (ObjectMessage)receiver.receive();
I used aqapi13.jar as I couldnt find aqapli14.jar in my Oracle DB.
Can some one pls suggest me what should I do to access AnyData AQ containing LCRs.
Can some one send me aqapi14.jar to [email protected] , so that I can test with this jar.
Thanks
siva

Hello,
You need to use the OCI driver as the error indicates.
The thin driver does not have support for the ANYDATA type in 10.2 only the OCI driver does. in 11.1 onwards the thin driver supports the ANYDATA type. So an option may be to use the jar files from an 11g install.
Thanks

Sender JMS Synchronous communication channel not picking up files from JMS

Hello,
One of our Sender JMS synchronous communication channel (used Sync/Async bridge in the module section to make it Synchronous) is not picking up files from JMS system though the channel looks to be active (greeen).
When I am trying to stop the channel, it is giving error as "1 of 1 administered and selected channels have not been stopped", and after this when I start the cannel again it shows green but not picking up any files.
if anyone is haivng any solution for this, please reply back.
Thanks in advance.

Messages available in JMS system? please check queue's if message were there and it is not picking up then some thing wrong with cc.
simple solution create new communication channel with same details and try to use the same.

How to Instantiate Oracle BPM Process Webservice from the OSB

Hi,
In our project we have one requirement i.e Instantiate Oracle BPM Process Webservice from the OSB.After register BPM service in to OSB I am creating one Message flow to instantiate BPM Process.
first call to startSession Operation, then use response of startSession operation is used as reqest for BPM process operation.
Can u tell me how do we use response of startSession operation to the request of BPM process.
Thanks in Advance.

An easier way of instantiating a BPM process via a WS call is to set the authentication type to 'Username Token Profile' on your web service operation in BPM studio and then redeploy it. If you use this type of security on your bpm process operations you can start the process in one call instead of having to get a session first and then starting the process.
Once you've updating the process, re-register the new process WSDL and business service with OSB (or import it manually) and you can just call the start process operation in one request (passing a username and password using the WS-UsernameToken method) without having to get a session first.
Hope this all make sense,
Mike.

Persistent messages are not deleted from JMS store

          Hi,
          I'm experiencing some unexperienced JMS store behaviour with WLS 6.1 sp 4. I have
          a servlet that posts a message to persistent JMS queue, which will be eventually
          consumed by an MDB. Even though consumption is successful, the message is not
          deleted from JMS store.
          The message will be redelivered after server restart and is still not deleted
          from JMS store. I verified this using file store and JDBC store. The messages
          actually stay in the JMSSTORE table till doom's day.
          I couldn't reproduce the case with WLS 6.1 sp 3. Exactly the application code
          was used in all cases.
          Subsequently I ran the same case with various ServerDebug DebugJMSXXX-flags set,
          and discovered that WLS 6.1 sp3 logs 'asyncDeleteL' and 'ZZZDelete' for the consumed
          message. WLS 6.1 sp4 didn't log this information.
          I'm running WLS 6.1 on WinNT and Win2000.
          Comments?

I've am having exactly this problem with wl 5.1....
          I first saw it with 5.1 sp8....
          In the release notes for 5.1 sp10, the following CR was fixed, which seemed
          like it might have been my problem:
          CR 45915
          Fixed a JMS problem with messages begin left in the queue after received messages had been acknowledged. When a high volume of
          messages was sent to a queue and a consumer retrieved those messages and sent them to another queue, the messages were not being
          removed from the first queue even though they were acknowledged.
          We upgraded to 5.1 sp12, and it appeared that the incidence of that problem was reduced.
          However it still occurs once or twice a week, with 5.1 sp12....
          My situation is a little bit different, in that my consumer retieves a message, and sends another
          message to the SAME queue instead of another queue as described in the CR above...
          It does happen under heavy load, etc....
          Don't know if this has been reported and identified for wl 5.1 sp12 or not...
          It is of course a really difficult to deal with bug....
