Why are my JMS messages automatically dequeued without consumer?

I created a simple in-memory JMS queue.
Now I wrote a BPEL process which writes (successfully ?) JMS message to this JMS queue.
Another consuming BPEL process is deployed but not started.
However I cannot see them in MBean JMSDestinationResource on the OC4J Enterprise Manager Web page.
When I tell the AppServer to browse all currently existing (and waiting) JMS message then there are none.
However the statistics for this queue show 17 messagesEnqueued and 17 messagesDequeued Messages.
It seems to me that my JMS messages are automatically dequeued. But why?
Are in-memory JMS messages not persistent (as long as the AppServer is up and running) ?
Do I have to set a certain preference to let JMS live in the Queue as long as they are not retrieved by another BPEL process?
Furthermore I tried the following:
I started a consuming BPEL process. Yes, he is waiting at the JMS adapter until a new JMS message arrive.
Then I send from the first BPEL process a JMS message. But even when consumption is possible the JMS message is dequeued and not forwarded to the consumer.
Why?

It seems to me that my JMS messages are automatically dequeued. But why?
This is how BPEL PM is designed; The activation-agent is running that belongs to the BPEL process. When a message arrives in a Queue or Table or File it is read into the dehydration store. Then an instance of the appropriate BPEL process is started. This functionality makes the system more stabel and reliable when something is goingin wrong in quees/files/db or any adapter that is used for polling.Are in-memory JMS messages not persistent (as long as the AppServer is up and running) ?
As you desribed: in-memory messages are only persistent in memory, if you restart the server, the messages are gone.Do I have to set a certain preference to let JMS live in the Queue as long as they are not retrieved by another BPEL process?
No you can not.Marc

  • HT4515 why are my text messages all of a sudden in green and do not say delivered?

    why are my text messages all of a sudden in green and do not say delivered?  Also for the first time since I obtained the phone I went to use the headphones and the insert to headphones is very loose and I can connect for about 10 seconds then nothing, I do believe it is the jack that inserts into the phone or the phone receptacle is bad or the headphone piece that goes into the phone is bad it is not working is the main issues.  Thank you

    Why are my text messages showing up on my wife's iPhone 6 and her test messages showing up on my IPhone 6?

    its because you guys are using the same Apple ID on both devices , when you use the same it connects to iCloud/iMessages so when ever you get a text on any other iPhone with there iMessages on its going to show on both devices because its the same apple ID that you are using for your iMessages , you can fix that buy gating a new apple ID for one of you ,ore go to your system preferences then go in to your iMessages  remove your email from there make shore its only your number on there ,but the best why is to get another Apple ID.

  • Why are some text messages blue and some green

    Why are some text messages blue and some green?

    Blue text messages are iMessages (with other iOS and Mac users with iMessage enabled).
    Green are regular SMS messages to non-iPhone users and iPhone users with iMessage not enabled.

  • Why are my text messages saving on my iPhone?

    When I swipe my screen to the left and the search is on the top, text messages from months ago and also recent ones are showing up. If I type in a certian word, all of the text messages that the word was mentioned in come up. When I try and click on any of the messages, it just brings me back to the last text I sent. Is this a virus? How can I stop my phone from doing this?

  • Why doesn't text message automatically fall back to SMS instead of options

    I have text messages set to iMessage ok and SMS okay.
    When a text message fails initially why isn't there a setting that the text will 'automatically' rollover to SMS instead of wasting time coming up with 3 options at the bottom of the screen, including sending as SMS?

    I believe that's because your forcing it to go as an SMS.
    One associated question. When a text is sent SMS is it solely routed through the carrier's (in this instance Verizon) equipment an lines and when sent as an iMessage is it routed/handled somehow significantly differently other than not charging the apple customer(s)?
    Yes, SMS is solely routed through the carrier's SMS system (does not require a data connection). iMessages are sent by either the carrier's data service or by WiFi to Apple's iMessage servers. Overall, SMS is more reliable. SMSs will go through when even voice calls may not. They can also be sent and received by "dumb" phones. But, they can't be sent/received by devices without cellular voice service. iMessages can be sent/received by iPads, iPod Touches, Mac computers. If the iMessages are sent or received using cellular data, they are charged against the user's data allowance.

  • Why are there pending messages that can't be consumed?

    Hi all,
    I am using Glassfish with a self made monitoring/stress-testing application.
    In this app I can define consumers and producers, so I can somehow see the behavior of the system under many different conditions.
    But something odd is happening: there are always 1000~2500 messages that I can see that they are there but I can't consume them. I have checked in my admin console and they are shown in the
    "Number of Messages Pending Acknowledgment - Current number of messages being held in memory and persistent store pending acknowledgment".
    Why they are pending acknowledgment? I sent them in the same way I did all others, and they all worked.
    I found this link, they are all having similar problems, but they are using ActiveMQ. http://fusesource.com/forums/thread.jspa?threadID=1060
    Could anyone help me to find out why this can be happening?
    Edit: Could it be that the acknowledgement of a consumer is not getting back to the queue and the queue is reserving the message to that consumer, so nobody else can consume it?
    Tks,
    Oscar

    Hi!
    Thanks you both for the answer. I just figure it out with help of your replies: I was using many threads to consume the messages, but these threads were sharing the same "MessageConsumer" object, what was causing the pending messages. Once I changed to have one MessageConsumer per thread, it worked.
    Thanks you both for the help :)

  • 8.1.5; why are .png colors inverted automatically but not .bmp?

    Adobe Acrobat Professional 8.1.5
    When using PDF creator to convert image files to pdf's; scanned images (from blueprints) with black backgrounds and white text/lines:
    if file type = .png colors are automatically inverted. (white background black text/lines)
    if file type = .bmp, colors are not inverted.
    Why is this?
    Is there a way to invert colors for .bmp?
    Thanks.

    Does anyone else have any other suggestions?  I work at a firm where Photoshop is not available so this is not an
    option.
    Thank you!

  • Inbox shows 1 unread message after opening all the messages.why are new inbox messages not highlighted

    I cannot find the unread message despite having opened all my inbox messages and wonder why the new messages are no longer in bold text.

    Right click the folder, select properties and then the repair button. A new index might clear it.
    If not try
    View menu > folders > unread see if Thunderbird can find it since it says it is there after an index rebuild.

  • Why are group text messages coming as downloads?

    Since I downloaded the newest droid softward my group messages which go out to iphone users are often coming back as a download.  The download often just keeps running or I have to go out of texting mode and go back in again to get the text.  This doesn't happen in individual texts to these people.  What can I do??

    If you text them a lot as a group, you should look into the GroupMe app. It's available for Android and iOS and can use either data or and SMS (so it can actually be used without the app). Basically, you post to the group and everybody gets it.
