Reading JMS queue

Hi all,
Reading messages from a JMS queue is possible using the JMS API. Looking up the topic or queue in the JNDI tree and listen for new messages.
When the client is deployed remotely (over Internet) it will be difficult to use JNDI to lookup to access the topic/queue.
Is it possible to use SOAP to read messages from the queue? SOAP will run over HTTP which will not cause any problems on the firewalls.
Any ideas on how to design these things is greatly appreciated.
Kind regards,

Problem Reading JMS queue

I have written a jms client to read a queue in weblogic. Specifically the wlai
event queue. However, I have tried to read other not-wli specific queues with
the same error. I get an access denied error even trying the system user!
I have even played with the ACL for the queue.
Anyone have any ideas?
Thanks

You need to add a 'browse' permission for your user to the ACL for that queue (or
the weblogic.jms ACL). It worked for me.
If you look in the stack, it mentions that your user was denied for the action
'browse'.

If still problem exists, can you post the exception and portion of your

Remember one thing when trying to listen on any wli specific queues:
there
might be MDBs that consumes the message before your client code canread
from the queue. So avoid creating listeners on wli specific queues.(topic
is not a problem)

BPEL not able to read JMS Queue defined on a remote Application Server

We are trying to access a JMS queue (defined on an Oracle AS different from the SOA Suite AS) through BPEL and read the payload. When I am trying to read the JMS queue, somehow it is trying to get the queue information from my local application server and not going to the remote one.
I have done the following setups on my local SOA Suite Enterprise manager for the queue connection factory. The adapter name is "eis/jms/XXXQueueAdapter"
connectionFactoryLocation: jms/ESBSubscriberQueue
factoryProperties:
java.naming.factory.initial=oracle.j2ee.rmi.RMIInitialContextFactory;java.naming.provider.url=opmn.ormi://hostname:port; java.naming.security.principal=oc4jadmin;java.naming.security.credentials=Password
Where "hostname:port" is for the remote Application Server.
On the BPEL side, I have created a connection for the Remote server in the Enterprise Manager. Then I have created a partnerlink using this connection. The OEMS is "File/Memory". The Destination Name is the Queue name on the Remote AS which I can browse. The JNDI name is "eis/jms/XXXQueueAdapter" (Which is the name of the connection I created on my local). Somehow when the BPEL process is run, it is trying to look for the JMS Queue on my local server.
I have also used the Third Party option instead of Oracle AS with the same configuration and it does not work either.
Any help would be really appreciated.

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,
          Kiran.

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.

Reading Message from Foreign JMS Queue in SOA Suite 11g.

Hi,
I am trying to read a JMS message that has been put into a JMS Queue on a remote weblogic Server.
The steps that I know is that I need to create a foreign JMS Server and then probably use JMS Adapter to subscribe to the message that is lying in the remote queue.
Has anybody been able to achieve this kind of scenario working for a remote JMS queue? Also, is this supported by JMS Adapter in SOA11g?
Any help will be appreciated.
Regards,
Varun Maheshwari

Hi Atheek1,
Thanks for your reply.
The confusion that is pondering me is that do I need to create a Foreign JMS Server or should I create a JMS adapter and override the properties.
I have tried the steps for creating a Foreign Server from the below link
Unable to access remote JMS Queue through JMS Adapter
But I am not able to find the Foreign Server created and any connection factories and Destinations related to foreign Server in my JMS Destination while configuring JMS Adapter.
I am not sure how to do step2 as entailed by you.
Could you please explain me in little detail on how to do this or redirect me to some blog or forum which will be really helpful.
Cheers,
Varun

You probably want to try the SOA Suite forum for OSB questions.

There is an excellent book also:

The documentation goes over the fundamentals, but the book will be better for step by step examples.

Maybe, your MDB "sometimes" throws an Exception in onMessage.

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

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.
