Writing to a JMS queue from Tux-service?

Greetings,
is there any way to write to a JMS-queue from a Tuxedo/atmi service without
using WebLogic Server (because of WTC needing it)?
Lara

Lara,
One way to write to a JMS-queue from a Tux service would be by using JNI functions.
Inside your server's tpsvrinit function you can create a JVM (using JVM_CreateJavaVM
function) and instantiate a couple of Java objects. You may then call Java methods
on these objects from your Tux services. At the server's tpsvrdone function you
must then destroy the Java objects and the JVM.

Need help to connect tibco jms queues from OSB

Hi,
We have a requirement in our project "to connect tibco JMS Queues from OSB".
The Queres are created by some othes in remote system, they provided us the details to connect the Queue. the detail are:
Queue Name :EXT_WEALTHHUB.TO_EXT.SYNC.REQ
Jndi Factory :SSLQueueConnectionFactory
and hostName , PORT
Credentails are provided.
We entered the same details in Business service in transport page by choosing 'jms' as protocol and EndpointURI as.
"jms://100.10.XX.YY:1234/SSLQueueConnectionFactory/EXT_WEALTHHUB.TO_EXT.SYNC.REQ"
And we created a service account to maintain the credentials and browsed the same at service account in the business service.
In JMS Transport Page we selected
Response Queue : One for all Request URI's
Response Pattern : JMS CorrelaltionID
Response UI :jms://100.10.XX.YY:1234/SSLQueueConnectionFactory/EXT_WEALTHHUB.TO_EXT.SYNC.RESP
when we are trying to establish a connection with the above queue getting

Migration of JMS Queues from Weblogic 10.3 to 12c

Hi - We are currently planning to move our JMS Queues from existing 10.3 server to 12c and for the same we are looking for some feedback :
We need to define a rollback strategy in case our migration to 12c does not work well and we need to revert back to using weblogic 10.3. Are messages sent to weblogic 12c backward compatible with version 10.3? As part of rollback, business would want to drain out any remaining messages from 12c and feed them back to 10.3 queues to allow them for processing. Is this feasible? If yes then, could you please suggest how, If not then could you please suggest a strategy for rollback and process remaining messages in 12c?
We would also want to know if we can keep the same Database for both 10.3 and 12c JMS persistent stores for the same queues or should we define a completely new DB? With weblogic we can define prefixes for the DB stores which would make queue tables to have different names between 10.3 and 12c for same queues. However we are not sure if there are any other internal tables that JMS creates in the persistent stores DB, not using these prefixes, which would then corrupt the data since both 10.3 and 12c tables would be on the same DB.
Thanks

NoClassDefFoundError while accessing JMS Queue from JDev 10.1.3.3

Hi,
I'm trying to get a handle of a JMS queue, which resides on Oracle App Server 10.1.3.4, from a Java Program which I'm trying to run from JDeveloper 10.1.3.3.
I'm trying to make an RMI connection to the App server from JDeveloper by passing following information to the intialContext:
env.put("java.naming.factory.initial",
"oracle.j2ee.rmi.RMIInitialContextFactory");
env.put(Context.PROVIDER_URL,
"ormi://wafedabpelqa10.corp.weyer.pri:12402");
env.put("java.naming.security.principal","oc4jadmin");
env.put("java.naming.security.credentials","welcome1");
Where the above information is related to our App Server.
I'm successfully able to establish an RMI connection from JDev to Oracle App Server and can lookup datasources created on the App server using their
JNDI names. However if I try to look up a JMS Queue from the App server using its JNDI name, I get an error as:
java.lang.NoClassDefFoundError: oracle/tip/adapter/api/OracleConnectionFactory
I have also tried to use the value "com.evermind.server.rmi.RMIInitialContextFactory" for "java.naming.factory.initial",
however I still get the same error.

Hi,
this should work and you need to download the rmi library http://www.oracle.com/technology/software/products/ias/htdocs/utilsoft.html
thanks

How to view messages in Jms queue from OEM 12c Cloud Control

Hi All,
How can I view messages in a Jms queue from OEM 12c Cloud Control without logging into WebLogic Administration Console?
Thanks in Advance!!

EMCC 12c gets down to the JMS message queue/topic level in regards to the metrics being collected. It doesn't provide a view into the actual messages themselves. Are you trying to capture/track messages with a particular payload?

How to Read Message from JMS Queue using Business Service(ALSB3.0)

Hi,
My Project Set up is as follows(using ALSB3.0).
1>One Proxy Service with transport as HTTP.
2>The Proxy service is calling another Business Service.
3>The Business Service has transport layer as JMS.
So here the business service is posting Request Message into the JMS queue.
I want at the same time it(The Business Service) should listen to another queue and from there it should read Response Message and forward back to the caller proxy service.
Can any one help me regarding this...
Thanks in advance...

Posting message to JMS queue from Proxy in OSB 10.3

I am posting a message to a JMS queue using a business service. Is there a way of getting a response from the business service to retrieve the newly generated JMSMessageID?

I am posting a message to a JMS queue using a business service. Is there a way of getting a response from the business service to retrieve the newly generated JMSMessageID?Yes JMS BS can be configured to get Response though from Different Q.
Request-JMSBS----->JMS Request Q------your logic outside of BS----->JMS Response Q----->JMSBS-Response. You can use JMSCorrelationID or JMSMessageID for the response correlation.

How to send to Weblogic 9.1 JMS queue from EJB running in Glassfish?

Hi.
I hope this is the correct forum.
I need to send a message to a jms queue on a remote weblogic 9.1 server. To this end I believe I will have to:
1) Install one or more weblogic client libraries/jar files on my glassfish application server. The weblogic server expects communication in the "t3" protocol, which I believe tunnels iiop, jms etc. inside their own proprietary protocol
2) Define the jms queue in my glassfish application server with a queue connection factory that creates the queue using classes from the weblogic jars?
3) Otherwise code the EJB methods sending messages as I would code and send messages to any jms queue
It's the first two steps that have me baffled. The more I dig in glassfish administrator's manual, the more confused I become.
Anybody have any idea if/how this can be accomplished?
Some reference to where I may find information as to how to accomplish this?
Thank you,
Jacob.

Jacob,
I suggest you try, either a GlassFish forum (http://forums.java.net/jive/forum.jspa?forumID=56), or perhaps the GenericJMSRA project https://genericjmsra.dev.java.net .This forum is primarily about the Sun JMS provider, Java MQ or Open MQ -- or the JMS Specification.

Integration with JMS queue from BizTalk 2013R2

Hi All,
We are planning to integrate biztalk application with Oracle Siebel CRM (8.1.1.11). they wanted to use JMS queue to receive xml message from BizTalk2013R2 and also send message to BizTalk for more reliability.
IS there any out of box adapter by which we can connect to their JMS queue.
We dont want to go with 3rd party software like jt adapter for JMS queue
Regards,
Manish
Manish

Hi Manish,
As of now there is no out-box-adapter for JMS queue.
If you don’t want JNBridge adapter (I hope you’re referring to same. There is no “jt” adapter as you mentioned), you can create a custom adapter which access the JMS queue.
Use WCF LOB adaper (WCF Lob
Adapter Wizard)and create an adapter.
Following article details about the .NET code for messaging with JMS queue, try the code.
Use JMS Messaging in your C# Applications
And following articles give details about using WCF LOB adapter/Wizard:
What Is the WCF LOB Adapter SDK?
Sample:
https://msdn.microsoft.com/en-us/library/bb798102.aspx
http://geekswithblogs.net/michaelstephenson/archive/2009/02/10/129302.aspx
Use similar code (one from above codeproject article where how to do messaging between JMS queue is shown) to wrapper it around custom WCF LOB adapter.
Give it a try, if you don’t want to spend anything on a 3<sup>rd</sup> party adapter.

M.R.Ashwin Prabhu

Receiving Unknown Byte Messages in JMS Queues from MDM 2.0

I am receiving unknown Byte messages in JMS CCB MDM Queue from MDM 2.0.
It keeps on increasing. Please let me know how to avoid this. and what may be the error.

Hi,
Set these flags with in your startup script like setDomainEnv.sh file or startWebLogic.sh file.
set these option near java_properties or options.
once you set please restart and one more point I missed here once you set these debug flags change the logging patter patter to debug mode under

change all the logging severity to debug mode and collect the debug.

Posting to JMS queue from WLI BPM 7.0

Hi,
I am trying to invoke a workflow process from a servlet by exchanging two JMS
messages.
I have configured my own JMS event queue com.bea.wli.bpm.EventQueueExt and generated
and installed the MDB for it as described in the docs. The servlet sends a XML
JMS to the normal com.bea.wli.bpm.EventQueue which starts the process. This half
works. The process then tries to send an XML to the newly configured queue - but
this fails.
The server console shows that there are absolutely no messages on my new queue.
The java servlet waits forever to receive on it and the workflow process instance
never completes the sending of the XML JMS.
I have attached the sample servlet code that I am trying this with. Would anyone
be able to spot what I am doing wrong?
1000 Thanks in advance,
Karsten
[BaseServlet.java]

Just wondering , why create a separate JMS server for this queue?
"Jared" <[email protected]> wrote in message

I am not sure if I exactly understand what you did -- but if you generatedanother
queue using the utility that WLI provided, I think you may be using itincorrectly.
That kind of queue is meant to be used in addition to the originalEventQueue
-- as an input queue to WLI. Maybe your messages were immediately sentback to
WLI -- in an attempt to start a workflow?
I would create a separate JMS server (from the WLI jms server) and createyour
queue on that server.

Consuming a jms queue from a multithread application

Hi
Thank you for reading my post.
I have an application which shuld consume message of a queue.
my application is multithread and what i want to know is:
- How i can ask queue to remove a message after my thread finished its work with the message, by this way i can ensure that if my thread face an exception after it read the message my message will not lose.
- As it is multithread application, How i can ensure that a message is not delivered to two or more thread? is there any way to consume the messages in a synchronized way?
Will synchronized access restrict the performance?
Thanks

This is running in a J2DK environment. For my thread pool, I just copied one from a Sun tutorial on multi-threading then modified it. I creaed a seperate package with three classes. Here is my thread pooling package. I basically use a Vector to hold threads when they are not working. And you can set a limit as to the max number of active threads.
package threadpooling;

* This class is simple to wrap the runnable
* thread for the worker thread around other

// Define the needed instance fields.
public Runnable taskAtHand = null;
public String taskType = "";
    // Overloaded constructor.
    public TaskWrapper(Runnable task) {
      // Just set the runnable
      taskAtHand = task;
      taskType = "WorkerThread";
    } // of overloaded contructor
    // Overloaded constructor.
    public TaskWrapper(Runnable task, String taskType) {
      // Just set the instance fields
      taskAtHand = task;
      this.taskType = taskType;
    } // of overloaded contructor
package threadpooling;

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...

OSB: Configuring business service for JMS Queue

Hi,
I want to produce messages into a JMS queue from OSB proxy service. I have created business service for the JMS queue. I also want to return Status code=200, Status Messgae=Success if the message is successfully inserted into the Queue. Kindly let me know how to do this.
I tried using Service Callout to call the business service but it is not allowing me to use it because my business service is a one-way operation. So, i tried with Publish activity but my doubt is how and where to configure request payload for the publish activity. I could not find any.
And how do i know if the message is successfully inserted so that i can send the Status=200 back to the calling proxy service.
Kindly help in this regard.
Thanks in advance.

As suggested, use QoS=ExactlyOnce as RoutingOption within the Publish to business service. If there was any error it will send the flow to error handler where you can do a reply with failure to return HTTP status code=500 to the caller of the proxy service.
If you do a reply with success the caller will receive HTTP status code=200
