Redelivery of messages to JMS queue

Hi,
          I am using weblogic 9.2 JMS and MDB for processing messages from queue. Only one instance of Container Managed MDB is running and the important point is that queue sequence should be maintained. I have a problem now. Each message will be picked by MDB and does some db lookups and it is sent over to another system. If there is any communication failure, the message has to be redelivered back to the front of the queue so that sequence is not lost. Even the same message is failing for more than one time, it should still be placed at the front of the queue becoz there is another mechanism that will pause the queue in case of communication exception.
          I tried with throwing Runtime exception but it is crashing the MDB and is getting deployed again which I think is not the right approach.
          I had set the transaction attribute as Required and tried to do setRollBackOnly on that for any exceptions but the message is not in the front of the queue. It is going to the back or somewhere in the queue.
          I also tried to put the message back with higher priority but did not seem to work.
          I have the redelivery delay as 0, I am not sure if I am missing any configuration settings. Pls let me know if there is a way to redeliver the message to the front of the queue for any exceptions in the message procesing by MDB.
          Thanks

Srini,
          WebLogic JMS' Unit-of-Order (UOO) feature was very specifically designed to handle strictly ordered message processing. The feature ensures that messages with the same UOO name are processed strictly in order - regardless of the number of concurrent consumers, redelivery delays, rollbacks, etc.
          If the entire queue is to be processed single threaded, you can very simply configure a default UOO for the queue, otherwise there are a variety of other UOO options. A good place to start is the JMS developer guide's UOO chapter.
          And yes, "setRollbackOnly" is the best way to force a rollback of an MDB CMT.

Unable to insert messages in JMS QUEUE

Hi All,
I am facing an issue while inserting messages in JMS queue.
The JMS Queue is on another weblogic server and now i created a bpel process which has a jms adapter to insert messages inthe jms queue.I am deploying the Bpel in my server which does not have this particular JMS queue.
I am unable to insert the messages into the JMS queue present on another weblogic server. where as i am able to insert messages if the queue is present on my server.
Can you please let me know if its possible to put messages into a queue on remote server from local server.
Thanks in advance.

Most probably it seems like an issue of security. Please try to establish cross domain trust between these two Weblogic server domains. For more information refer to http://download.oracle.com/docs/cd/E1284001/wls/docs103/secmanage/domain.html#wp1175687_

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

How to read Java Object message from JMS Queue using JMS Adapter .

Dear All,
In my scenario i have to read a java object message from JMS Queue . I tried by using the JMS Adaper ,but i am not getting any Payload . Can any one tell me is there any special settings for JMS Adapter to read the Java Object message .
I am able to read the Message successfully thru JMS Adapter but in SXMB_MONI it is not showing any payload .
I also went in Message monitoring but i am getting this type of message in Sender JMS Adapter in Audit Log.
JMS Message ID XXXXX Message Type Null unknown.Payload can not be read and will be empty.
JMS Message ID XXXXX Payload Empty can not read.
Please Help.

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.
(Refer to SAP note 856346)

I want to use ODI to read XML messages from JMS queue and then process it..

I want to use oracle ODI (Oracle Data Integrator) to read XML messages from JMS queue and then process it.. i also want to process and validate the data in it....
Could anyone please tell me the steps to achieve the same. I tried some ways which i got on OTN, but not able to implement it exactly...
As i m very new to ODI, it will be great if you provide detailed steps..
Thanks in advance for your help....

Hi,
Were you able to do it? We are facing this same issue now and, despite the fact the docs say otherwise, it does not seem to be a trivial task.

Posting a message to JMS queue using B2B

Hi,
Could anyone suggest a solution for this scenario?
I have two trading partners say TP1 & TP2. Suppose TP1 is sending an xml message to TP2 using custom ebMS protocol, then at TP2, the message should be posted to a JMS Queue so that some other application can read it and process it.
The problem which I am facing is..
1) where to create that JMS Queue(I could not find any options for creating a JMS Queue neither in B2B console nor in enterprise manager console..!!)?
2) how to register TP2 to send msg to that JMS Queue(How that queue will be vissible to B2B)?
3) Should the endpoint be given as that JMS Queue while configuring the Delivery Channel for TP2?
Thanx in advance for your suggestions,
Regards,
Satya.

Hi Narayanan,
Thank you for your prompt reply. I understand that we need to create an external delivery channel to post the message to a JMS Queue from TP2. Currently I am using default AQ's (b2b.IP_IN_QUEUE & b2b.IP_OUT_QUEUE) at TP2 end to receive the message.
But, I want to post the message to JMS Queue. For this I need to create an external delivery channel and the corresponding end point should be the name of that JMS Queue. Is my assumption correct?
I have already gone through the thread that you have mentioned and the pdf as well. But, I am not able to find an option on how & where to create that JMS Queue?
Could you clarify on this?
Regards,
Satya.

QueueBrowser not scaning all messages in JMS queue (ie not showing inprogre

Hi all,
I am using JMS in jboss-3.2.3, when scaning for pending messages i am using QueueBrowser.
But QueueBrowser not scaning all messages in JMS queue (ie not showing inprogress message)
But i need to know all messages including ongoing messages..
Antone plz help me
I am using Queuesender and QueueReceiver ..But some Exception or Error causes my JMS server(QueueReceiver listening for onMessage()) hanged up..and not responding to remaining messages...So i need to find pending messags in JMS queue..How can find?
Now i am using QueueBrowser to get list of pending msgs in queue... But doesn't contains Message which passed for processing (called onMessage())
.. But i need to find this also..How can?
Thanks,
Thilsen

You're right in thinking that the behaviour you describe looks wrong.
Take a look at the QueueBrowser interface which can be used to inspect a queue. You get one using QueueSession.createBrowser(Queue). The QueueBrowser allows you to scan a queue without consuming the messages. However note that the state of the queue may change while you're observing it through the QueueBrowser so what you see might not always be a 100% accurate representation of the queue at any given time.
Other things to check:
- message selectors - are you setting a message selector on your queue receiver which is resulting in not all of the messages 'matching'.
- expired messages - are you setting a time-to-live on the messages that you publish.
Hope this helps,

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.
We have set up the expiration scan time interval. See a portion of our config.xml below:

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

Hi,
Even i have a similar kind of requirement where in, i want to clear the JMS Queue Message programmatically, on certain condition.
i am using Spring JMS. The JMS Queue has a listener. In the listener we want to clear the Queue contents based upon the condition.
If anybody has any idea about this, please reply back.
Thanks in Advance.

Making DB updates and sending message to JMS queue enclosed in a single transaction

          using a container managed transactions can we achieve sending a message to the JMS
          queue and updating DB as part of single transaction with the data base driver not
          supporting XA. If yes what all configurations setting I need to do. I tried to achieve
          this using 2PC but I am getting the error that "javax.transaction.xa.XAException:
          JDBC driver does not support XA, hence cannot be a participant in two-phase commit.
          To force this participation, set the enableTwoPhaseCommit property on the corresponding
          JDBCTxDataSourceproperty, to true. Pool = ejbPool".


As far as I know, your only options is to do as the exception you cut-and-pasted below
          states:
          "To force this participation, set the enableTwoPhaseCommit property on the corresponding
          JDBCTxDataSourceproperty, to true. Pool = ejbPool"
          The "enableTwoPhaseCommit" property has definite drawbacks
          see the javadoc and/or documentation for configuring
          a "JDBCTxDataSource".
          This problem is specific to non-XA resources in general, not JMS (which is an XA resource),
          you may wish to get more info by posting to the transaction newsgroup.
