Fetching from JMS Queue

Dear Experts,
I have the necessity to fetch messages from a JMS queue sequentially, not in a multithreading way. There is a configuration that allow me to do this ? I explain better, if I have 3 messages in a JMS queue, I should need that only when my proxy services has terminated processing of first message the second message in queue can be fetched and processed and so on.
Thanks,
My Regards,
Mike

You have to associate the proxy service with a work manager that has a max thread constraint of 1 , through the dispatch policy configuration.
Also set messages maximum on the connection factory used to connect to the queue to 1. This will ensure messages are still processed in order when it is redelivered.
You use UOO to parallelize message processing across different groups while maintaining sequencing within the group. And this has to be set by the sender of the message. I believe you are concerned about sequential processing by the receiver.

Hi,
As far as i know, JMS Object Messages is not supported by XI JMS adapter.
you need to have the JMS provider to transform the message to bytes messages.

Data retrieval from JMS queue using single SOA composite in a clustered env

Hi,
I have following situation:
1) A requester SOA composite (Composite1)is reading data from a File
2) Mediator is routing data received from Composite1 and writing in a JMS queue.
3) A provider composite (Composite2) is reading from the JMS queue.
Both Composite1 and Composite2 is deployed in a clustered environment.
Problem is Composite2 is not able to read data sequentially from JMS Queue sometime (for example out of 30000 transactions its failing once). Here it's a queue and only one producer and only one consumer is there.
What may cause this issue? I thought a single producer and single consumer on a queue will guarantee FIFO retrieval . Could you please advise where may be the gap?
Thanks
Edited by: user1054373 on Sep 18, 2012 11:29 PM

Hi,
I thought a single producer and single consumer on a queue will guarantee FIFO retrieval Java Message Service Specification does not guarantee ordered message delivery when applications use distributed queues...
Using Weblogic Message Unit-of-Order may solve your issue...

Recieve/Read Messages from JMS Queue through ALSB

Hi,
I have configured JMS Queue in weblogic server.
I have created Messaging Service in ALSB which sends messages in MESSAGE QUEUE.
Now Is it possinle to receive messages from JMS Queue by creating business service in Aqualogic Service bus???

Hi dear,
 
I am sending Message through Serializable Object.
 
I have JMS Proxy which gets invoked when i send message to JMs Queue. JMS Proxy then calls business service.
 
 
Business Service has two functions. One is taking String as input and one is taking Serializable Object as Input.
 
 
public void recieveString(String str) 
public void recieveObject(Trade obj) 
-------------------------------------------------- 
Now I have configured Proxy Services' Request and Response
Message Type as a "TEXT". and I am sending ObjectMessage here so what kind of change I require.
 
I also want to configure my proxy so that if JMS queue recieves TextMessage then it should invoke reciveString() function and if Object Message then vice versa.....
 
But i am not able to handle object even...
When I am sending Object Message it takes as a TextMessage.
I am getting following exception when I am sending Object Message to JMS QUEUE. Request and Response Message types are XML Schema of that object.

How to get the XML messages from JMS Queue in BPM

I have one requirement in my application.we are sending XML messages to the JMS Queue.How to get the XML messages from JMS Queue and how to Extract the details from XMl.
can you please send me the code to get the XML messages from the JMS Queue.
Thank you,

Hi,
Sure others will have some other ideas, but here's what I typically do to get the XML from a JMS queue. Inside the Global Automatic that pops the messages off the queue you'd have logic similar to this:
artifactInfoNodes as Any[]
xmlObject as Fuego.Xml.XMLObject = XMLObject()
load xmlObject using xmlText = message.textValue
. . . Once you have this, it's a matter of deciding what you want to do with the message. Most times you'll parse the XML (using XPATH statemens), set argument variables and create a work item instance.
Hope this helps,
Dan

MDB,MDB container or JMS adapter stops processing messages from JMS queue

Hi guys,
we have created a component using Enterprise Java Beans, let's say a product catalog, deployed it on a Glassfish v2 instance, and connected it to a legacy system using JMS and Sun MQ v4.1 as messaging system. The catalog component thus starts one MDB that listens on a JMS queue, let's say a queue named catalog_business_events_in, and waits for incoming messages, i.e. in our case update events. The problem is, that in general this approach works well, but sometimes the MDBs/JMS adapter stops for some reason fetching and processing messages from the JMS queue. We don't know why - no exceptions, etc.. Seems to be a Glassfish EJB container, JMS adapter or Sun MQ configuration issue. It seems to be that our component is not the problem.
The messages are compressed/uncompressed by Sun MQ automatically. We actually have 2 Sun MQ instances in clustered mode running to have some kind of failover - no HA cluster, yet. Sun MQ instances are accessed from Glassfish instances running in different Glassfish clusters - so we have a dedicated Sun MQ cluster not a Sun MQ instance per Glassfish instance. Each Glassfish instance is configured such that it knows both Sun MQ instances to allow automatic failover.
Has someone an idea, why the MDBs/ MDB container/ JMS adapter - stops processing messages? We are kind of puzzled as it happens more often now and apparently when traffic is (very) low not high!
Thanks for your help.
Cheers,
Martin

Dequeue from JMS Queue 10 at a time and process it.

Hi,
I have created a JMS queue in weblogic.
Say i enqueue 1000 records in the queue at one go.
Now, i want a bpel process to dequue from it and process it.
However as per my requirement i want at a time 10 instances being active at a time i.e. 10 records from the queue are being processed at a time.
Once any one of them finishes, the other will pick up the message.
1 BPEL instance will process only 1 record from Q at a time
Please let me know how to achieve this.

You need to understand here that it is adapter which deques the message from queue and it will deliver it to BPEL for processing which is an async process. So adapter will keep dequeing messages and keep publishing it to BPEL irrespective of whether BPEL process has completed processing.
You may need to tweak the adapter configuration here. First of all create the synchronous BPEL composite so that both adapter and BPEL work in same transaction -
https://blogs.oracle.com/adapters/entry/creating_a_synchronous_bpel_composite_using_file_adapter
You may control the number of threads for inbound JMS adapter using binding property "adapter.jms.receive.threads" in composite.xml

Exception in the XML consuming from JMS Queue

In the CEP application we have a business flow like we want to consume an xml message from the JMS queue.
While CEP is consuming the message sometimes we are getting an exception.
But this issue occurs rarely and we have no idea about the root cause.
I am attaching the trace of this exception.
It seems this exception is from weblogic server itself.
Also this could be an interface problem, since its showing a casting error.
The Bug description:
When we send a meter event through SOAP UI in the CEP visualizer when the event is consumed CEP also shows this exception.
This may not halt the analysis process of the event, but this unwanted piece of code/lines have to be avoided.

OC4J 9.0.4: Problem receiving message from JMS queue

I've created an application which puts XML files in a JMS queue and try to get it out again. The enqueing (sending) is no problem, but when I dequeue from the same queue I receive nothing and if I don't specify a wait time the programs hangs.
If I create a QueueBrowser I can see there are messages in the queue.
Can someone tell me what I do wrong?
Here is the code of my dequeue action:
public String dequeue(int qName) throws RbsSysException
        final String method = "dequeue(int qName)";
        _log.debug(method);
        QueueConnection queueConnection = null;
        try
            queueConnection = _queueConnectionFactory.createQueueConnection();
            QueueSession queueSession = queueConnection.createQueueSession(false,
                    Session.AUTO_ACKNOWLEDGE);
            QueueReceiver queueRcv = queueSession.createReceiver(getQueue(qName));
            _log.debug("queue = "+ queueRcv.getQueue().getQueueName());
            // Due to bug 3376983 in OC4J We cannot use TextMessage if it exceeds
            // 64 kb. Therefore use ObjectMessage.
            Message msg = queueRcv.receiveNoWait();
            _log.debug("msg = " + msg);
            ObjectMessage objMsg = (ObjectMessage)msg;
            //ObjectMessage objMsg = (ObjectMessage) queueRcv.receiveNoWait();
            _log.debug("objMsg = " + objMsg);
            if (objMsg != null)
                return (String) objMsg.getObject();
            else
                return null;
        catch (JMSException je)
            throw new RbsSysException(je);
        finally
            if (queueConnection != null)
                try
                    queueConnection.close();
                catch (Exception any)
                    _log.error("Error while closing QueueConnection: ", any);
    }

Did you implement javax.jms.MessageListener and the method onMessage(Message)?
If you use onMessage() as wel as receive (or receiveNoWait() or receive(long)), the onMessage() can be called, while the main thread is blocking on a synchronous receive, so make sure you use only one of the two methods: onMessage() or receive.
Receive() blocks your thread until a message is published. So your program 'hangs' by design. Usually this is used when your program is waiting for a particular message. Otherwise use onMessage().
ReceiveNoWait() checks if something is in the queue at that very moment, so if nothing is there (yet), the main thread continues.
Hope this helps,
Lonneke

Weblogic 10.3 Not Removing Expired Messages from JMS Queues

Dear All,
We have an application that is running on Weblogic 10.3.
This application (let us call this application Y) receives messages on a JMS queue. These messages are placed on the queue by another application (let us call this application X). We would like to have these messages expire within a certain amount of time (i.e. 90000 ms) if they are not consumed.
Now when application X places the messages onto the queue for application Y to consume, the JMS producer sets the time to live to 90000 ms. We can see that expiration time has been set appropriately in the weblogic console. If a message sits on the queue for longer than 90000 ms the state string of the message is changed to "receive expired". What we don't understand is why the expired messages still end up being consumed from the queue.
We understand that Weblogic is supposed to have an 'Active Message Expiration' thread that will remove expired messages from the queue. The Expiration Scan Interval for the JMS Server is set to 30 (seconds).
Can anyone tell us why our expired messages don't seem to be deleted from the queues?
Tim

Thank you for the response Rene.
We have set up both the active expiration scan and the message expiration policy. The active expiration scan is set for every 30 seconds. The message expiration policy is set to "discard". However, the expired messages are still being consumed. Is it possible we are doing something wrong? See a portion of our configuration files below.

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
Phani
