JMS message filtering

Hello

can we filter JMS message form



Thank you

I could not understand the question, but according to my knowledge, selector of JMS messages is static configuration and must have the exact value at the time of the design itself which is the way it currently works. What you're looking for is "way to assess the selection criteria based on the expression at the time of execution". I don't think that he is currently supported.

If we descend into thinking more than why this behavior, then we can say that if we want to execute logic, so we have to instantiate who hold the variables and evaluate expressions of a thread, but Message selector is nothing, but subscription so property whenever a Subscriber is stored in the JMS server he hears message based on it and when something specific Vienna then only he initiated a thread for subscriber process further.

What will be needed in your case, it's this Subscriber subscribe all messages and will initiate the thread and then reject the message based on the logic of the selector within the scope of the processing thread. I don't think it will be good idea because it will instantiate many unnecessary wires in a business solution. This will be equivalent to an if-else in the pipeline early condition to reject unwanted messages. The whole idea of having Message selector must give this responsibility to the subscription instead of the Subscriber. I don't think that selector messages JMS should work this way.

I hope that I have understood the question correctly and especially the help of details mentioned.

Kind regards

  • Upgrade to Windows 10 and the lost message filters

    Upgrade to Windows 10 last night after having made a backup of Thunderbird with MozBackup. Profile of the restored this morning and lost all my message filters. Also lost all of my archived messages. Changed the path where Thunderbird search messages and more archived returned messages but still have no message at all filters.

    in using the menu, select troubleshooting.
    Select the button view profile.
    Close Thunderbird.
    Delete everything in the open folder, including subfolders.
    Replace it with the same folders of your mozbackup (change Zip file extension and the Treaty as a zip file).
    Launch Thunderbird.

    Now you should have all the right files in the right place, so everything should be back.

  • A JMS message is not a property of the unity of the order and a unit of work property


    I received this message on my side Client of JMS:

    weblogic.jms.common.JMSException : A JMS message is not a property of the unity of the order and a unit of ownership of the work

    I put only the unit of work properties in what follows.  Don't know why he complains that I put together.

    This is the code that actually works!  I changed to PUA, however, based on the characteristics of our company. Now the Weird message of "properties have PUA both UOW" disappeared!

  • Treatment of JMS messages in order one after another

    It's my use case that I wan to implement in OSB.

    1. I have a queue that will receive the messages in the huge number of a single sender.
    2. I have a proxy that will read each message and process the message and send it out.

    In step 1, I want each message to be read in order and at step 2 end run, then I want to read the next message in the queue.

    I need to give an acknowledgement to JMS message processing is complete and it can make the next available message to the proxy.

    What is the best option to implement this use case?

    Concerning

    The WebLogic jms to order unit is the best approach for this.

  • JMS Messages, refusing to participate in JTA transactions

    I worked on this issue for several days, and I can't find a path.

    I have a situation where I have to write in the database and also to send a JMS message. I want both to work, or nothing works, so it's a simple application of JTA, so I think.

    The used JMS connection factory is located to participate in XA transactions (I checked that 10 times).

    I originally had a UserTransaction started and committed around these statements, but since that doesn't seem to work, I put all the code in an EJB with transaction required.

    Whatever it is, it does not the way I expected.

    I have a breakpoint in the MDB which receives the message, but also a breakpoint on the Publisher code, and the code immediately after him. I find whenever as soon as I didn't have the JMS publish, the breakpoint in stops MDB then, indicating that the JMS message has been sent, even if the transaction publishers is certainly not over - finally the debugger will return back to the line after the publication.

    I am sure that we have made repeatedly in the past, and it worked as I expect with transaction code works.

    Someone has ideas about obvious things to check to determine why the JMS message is outside the transaction? Or not so obvious...

    Thanks in advance,
    Ken clark

    Hi Ken,

    You reason - the use case is common, but there are has some pitfalls new users sometimes face.

    The results of tracing of breakpoint you are expected. Message from a sender goes to the JMS server while sending message is called. If the message is involved in the transaction, it is always sent, but it became visible to consumers until the transaction is subsequently committed.

    To ensure that a sent message is involved in a transaction:

    1. ensure that the connection factory is «activé XA»

    2. ensure that there is a transaction on the thread. For example: System.out.println ("MY TX" + weblogic.transaction.TransactionHelper.getTransactionHelper () .getTransaction ());

    3 - ensure that your connection.createSession () invoking past 'false' for the first parameter - not true! If true and that you do not use a resource ref, the session would then become a "transactional" session, and JMS messages will take part in an independent local transaction rather than the overall XA transaction

    4. If not using a WebLogic JMS to send, then you must make sure that WebLogic automatically entered the foreign seller send call in the WL TX. All that is needed is to use a standard JEE 'refers to a resource"to get him CF. rather than directly raising the CF foreign in the foreign JNDI provider. This enables WebLogic detect and wrap calls foreign seller of the application, which in turn allows the automatic registration. See the JMS WebLogic Interop FAQ for more information.

    4 b - If you use AQ - JMS to send, more work is required, since QA - JMS are quite unique among the JMS implementations. WL 10.3.1 and later provides features to simplify this work.

    See for a related FAQ [integrating remote JMS providers | http://download.oracle.com/docs/cd/E15523_01/web.1111/e13727/interop.htm#JMSPG553], and for resources info Ref see [support strengthened using WebLogic JMS with EJB and servlet | http://download.oracle.com/docs/cd/E15523_01/web.1111/e13727/j2ee.htm#g1329180] (especially the 9-5 example).

  • How to send a JMS Message to a process of BPM

    Hi all

    I have small question regarding the sending of JMS Message of a bpm process. Is it possible to send a bpm process JMS messages to another bpm process.

    I have a scenario in which I need to send a JMS message to a queue, where another process is listening on this queue, and upon receipt of the message in the queue that is created for the process instance.

    I know how to listen to the JMS message on the queue, but I did not how to send a message to a process JMS.

    Also can I create processes by sending Notification to the process instead of a JMS message. But the creative process isn't a subprocess i.e. a declaration can be addressed through different processes.


    Any information or the example in this respect would be useful.

    Thanks in advance

    Published by: user9945154 on April 22, 2009 19:46

    Hello
    Daniel already told you how to send a JMS message.

    To send messages between different processes, you can use the Notification component:
    http://download.Oracle.com/docs/CD/E13154_01/BPM/docs65/standard_components/Fuego/lib/notification/Notification_component.html

    To create an instance of another process, you can use the ProcessInstance:
    http://download.Oracle.com/docs/CD/E13154_01/BPM/docs65/standard_components/Fuego/lib/ProcessInstance/ProcessInstance_component.html

    If you want to create an instance of another process, I recommend you ProcessInstance component because the creation is done in the same transaction. That has advantages:
    1 - is much faster!
    2. it is performed in the same transaction. Thus, you will be sure that the instance has been created.
    3. you don't have to wait until the arrival of the notification. (Sometimes, this reduces the interprocess synchronization)

    Hope this helps,
    Ariel

  • How to effectively create message filters?

    Hello

    I have dozens of filters, just move messages to an appropriate folder, such as social networks, services, forums, mailing lists and so on.

    It's a pain to create a filter whenever a new unclassified message arrives. In addition, it takes a lot of time, 1 min or more to run all the filters on my Inbox.

    Is there a better way to do this? I wanted to say "messages like that will go in this folder" simply by dragging or so.

    Instead, I have to:

    1 copy 'from' address
    2. open the filters
    3. Select the appropriate folder filter
    4. scroll through the list of rules and add a new
    5. apply the filter to the Inbox

    If there is no better way, how can I suggest such an improvement? It seems that the IRC channels provide no help on this.

    Thank you.
