Hi,
I'm trying to browse a queue with MQQueueBrowser with a JMSMessageID selector - it fails, but get works perfect.
also when I m browsing , by for ex. JMSPriority , it works.
Does that mean that I can't browse by msgid and have to do the searching on the enumeration I get?
Thanks  |

OK, our network is not connected to the Internet so I can't copy paste the code.. I hope I don't make some stupid mistypes. Here is approximately what I'm doing:
| Code: |
public Enumeration getBySelector( String QMgr, String queue, String selector ){
MQqueue q = (MQMueue)session.getQueue("queue://" + QMgr + "/" + queue + "");
QueueBrowser b = q.getBrowser(q, selector");
return b.getEnumeration();
}
in Main:
getBySelector("",TEST,"JMSMessageID = ID:*")
where * is an existing ID (can't copy-paste a real one)

check out the manual. I think you might be missing some quotes. I believe it should look like this:
| Code: |
Selector = "JMSMessageId = 'ID:*'"; |
As ID:* is not a variable but a value assignment.
Enjoy

I was afraid I would make a stupid mistale .
I'm indeed trying to browse with 'ID: *' - to be more precise I do it exactly as when using receiver and it doesn't work.. Any ideas?
bower5932: thanks for the examples, I'll check them out. |

When you browse is your connection started or stopped ?

Thank you for your efforts man.
Let me explain myself:
I start the connection of course and in the same session I try to do the following:
Get | Get by msgid/correlid | Browse | Browse by msgid/correlid |
----------------------------------------------------------------------------------
OK | OK | OK | fails |
----------------------------------------------------------------------------------
It's very strange as the syntax for getting/browsing by selector is exactly the same and get more and more convinced that it is a bug or smthing..
I've read the whole chapter about using selectors and have searched the net for browsing. Nothing special about it and yet browsing by an ID fails for me. I tried to browse by priority(JMSPriority) and it worked.. ????
Have you tried browsing by msgid/correlid? Is anyone that has done that using JMS ?
Thanks again,
Joseph |

Well.... If you get the message by correlId it is no longer there for you to browse isn't it?
Reverse the order of your test and do the browse before you do the get.
Enjoy

| I thought he was doing two gets (both working) followed by 2 browses (first works, second fails). Shouldn't this be correct? |

I guess FJ's point is that this is correct only if there are at least three messages on the queue, all with the same msgid.

Friends... My point is that I fail to browsae by msgid/correlid..
I'm not doing all of those operations at once in one run and I know that if I GET a message it is no longer there. Just this:
Put a message to a queue -> Copy its msgid -> try to browse it using JMS selector (and I assure you that the syntax is correct) -> the browse returns no message -> fails. OK?
I hope we'll understand each other this time 
Thanks  |

Are you doing all these operations using one application ?
Do u see the message in the queue(with the correct id) till the end ?
Please post the code snippets of your put, copy of msgId, and browse...
Regards. |

Ok, as I told you I have no possibility to copy-paste code as our network is not connected to the WWW, so don't catch me on syntax errors that I might make. I do it analogically to the QueueReceiver which works with any selector I have tried so far..
So here we go:
| Code: |
public Enumeration getBySelector( String QMgr, String queue, String selector ){
Queue q = session.getQueue("queue://" + QMgr + "/" + queue + "");
QueueBrowser b = q.getBrowser(q, selector");
return b.getEnumeration();
}
in Main:
getBySelector("",TEST,"JMSMessageID = ID:*")
|
where * is an existing ID that I have copied from the Windows MqExplorer after having put the message (can't copy-paste a real one)
As I wrote earlier, if I substitute the QueueBrowser with a QueueReceiever, (with all the necessary changes of course) the receiver returns the message that I requested(another message with its id taht I also copied from the MQExlorer).
If I still am not qite clear, just try to browse for a message with an id selector please. If you have a jms apllication it won't take you more than 5 minutes.
I need it to work badly, thanks so much,
Joseph |

Don't cut and paste. You do not know that the format is correct. You might need to use lower case letters ('a-f') or upper case ('A-F') where you are using the other. The only way to get it right is to put the message, get it's JMSMessageId (see method on the message) and then use this information in your selector...
Enjoy
