Read message synchronously from JMS queue using OSB

Hi,
Is it possible to read message from the JMS queue using OSB based on the request invocation. I know messages can be read from the queue but it will be polling based.
The requirement is to have an OSB proxy service (HTTP service ) an an interface to the client application. Client application invokes the proxy service and the proxy service need to read message from the JMS queue and provide the message as response to the client.
Let me know if there are any pointers.
Thanks
Sandeep

Hi,
I spent some time trying to do this and apart from creating custom database tables etc. I was not able to achieve this.
We wanted to use in memory JMS queues in our situation.
In the end we developed a Java Web Service which preformed the on-demand read from the queue (using a particular message selector)
This is working for us without a problem

How to read the messages in the JMS Queue using JMX

Hi,
          I want to read messages in the JMS queue using JMX. I was able to read using QueueBrowser but want to modify priority of the messages using JMX.
          I tried to use JMSDestinationRuntimeMBean but it does not allow us to read messages unless we pass the message Id. Is there any way that I can get all the messages in the queue.
          I am using Weblogic 8.1 SP4
          Can someone please help me in this regard.
          Thanks,

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

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...

Sending messages concurrently to JMS queue

Hi,
I am using Weblogic 10.3 JMS. I have a .NET producer sending messages to a JMS queue using a threadpool. A Java consumer will be consuming the messages. Is it possible to pool the conections/sessions from the producer side to send messages concurrently from the threadpool. Please help.

You can use standard .NET threading to produce messages in different threads.
Keep in mind that producers and session instances themselves must not be multi-threaded, although they can all share the same connection.
When you code, each thread could have a dedicated session and producer.
Alternately, you could write a very simple pool that the threads share to cache producers. On the other hand, sessions and producers are light-weight once they've been created, so there's often little need to go through this trouble.

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.

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.

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

Add a JMS correlation id manually before posting it to a queue using OSB

Hi All,
Background:
A proxy services (HTTP) recieves a raw xml message. This is routed to a business service , which will post to a JMS queue on weblogic.
Requirement :
We need to add specific data from body as correlation id to the JMS message that will be posted to the queue.
I know this may sound weird but the application which is consuming the message from JMS queue wont work without this correlation id.
Please let me know if somebody have some idea to implement this through OSB.
Thanks in advance :)

Hi Harry,
Inside your route, add a Transport Header action.
Direction=Outbound Request
Click on "Add Header".
Select Defined=jms, and select CorrelationID
Then set the expression

It seems to be doing a JNDI lookup, and you haven't configured JNDI properly. Exactly how to do this depends on what JNDI provider you are using. Earlier in the thread you mentioned you were using WebLogic, so the answer may lie in the WebLogic documentation.

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.
