Creating topics and queues programatically
Hi,
Here i my scenario.
1. I have created the required number of queues and topics using the SunOne MQ's imqcmd command.
2. I want to use the jndi apis to register the jndia names for these queues in the appserver. How do we do this?
3. How to make an entry in the server.xml file programatically?
Note:- i do no t want to use the asadmin-utility for this.
i want to use the standard api's available to do this task.
Pls help
regards
raghu
Hi Raghu,
You appear to have created various topics and queues
on a MQ broker via the imqcmd command (independent
of app server).
For JMS clients to access/use the above topics/queues,
JMS resources of type javax.jms.Topic and javax.jms.Queue
need to be created and exposed to app server's JNDI
context.
Running this command:
asadmin create-jms-resource ...
Creates a new jms-resource entry in server.xml and
the command:
asadmin reconfig ...
Creates the actual java object and introduces it into
app server's JNDI context. (A server restart does this too).
You mention that you want to do the above from your code.
I don't think it is possible to programatically add new
resources into server.xml. If there was a way, I wouldn't
recommend it be done from J2EE applications since JMS resource
management is an administrative task. Note that using
JNDI to bind an object from an application (I haven't tried it
in app server) may appear to work but this resource is not
persisted across restarts since it is not in server.xml.
Why do you want to do this ? Why does your application need to do
what asadmin already does today ?
Perhaps if I can better understand why you want to do this I can
help suggest other solutions.

Can JMS topics and queues be clustered in a WLS 7.0 Cluster?
We are installing a weblogic 7.0 cluster with 1 admin server and 2 managed
node servers. Two nodes have been clustered. We are at the point where we
need to configure JMS. Has any one implemented JMS in WLS 7 clustered
environment? What are the things to watch out when clustering JMS? Can JMS
topics and queues be clustered?
TIA for any helpful hints and comments.

I'm currently working on a project with WLS 7 here at work, involving
the implementation of BEA's JMS Cluster. So far, I really haven't had
many hiccups.

At least in WLS 7, the biggest thing that stands out is the lack of
automatic failover. Also, Message Paging -- make sure you configure
paging high/low thresholds. Or, if you don't wish for it to occur but
can't stop the server (very common these days with SLAs), set that
byte/message high threshold to a very large number (correct me if I'm
wrong, but I believe BEA recommends 2^63 -1).

>> Can JMS topics and queues be clustered?
Well, since Topics and Queues are extensions of the
javax.jms.Destination interface, the answer is: Yes!
(SIDE NOTE: most people usually refer to them as a [JMS] "destination"
-- it avoids a lot of conceptual baggage and plus, less typing!)
You'll probably want to see this section of BEA's e-docs:

Creating a destination queue programatically
Is there any way to create a Destination Queue for a Connection Factory through my Java program, if I do not want to do it through the Admin console?
Specifically, is there an API to create a JMS queue?
Thanks.What do you mean by creating Queue for ConnectionFactory? ConnectionFactory is to create connection to the JMS server.
JMS provides methods like createTopic and createQueue but they are for converting provider specific name into Topic or Queue object for destinations already existing. One can not create physical destinations through these methods. Exception is for temporary destinations. Methods are createTemporaryQueue and createTemporaryTopic. Their life period is that of the connection. They will be garbage collected when the connection is closed.

Distinguishing between topics and queues
Hi,
I have a generic piece of code that takes a javax.jms.Destination that does different
things depending if the destination is a queue or a topic.
The problem is that it seems that destinations in Weblogic implement both queue
and topic:
instanceof queue <new_JMSTopic_1>
queue name: <new_JMSTopic_1>
weblogic.jms.common.InvalidDestinationException: Destination must be a queue,
ne
w_JMSTopic_1
at weblogic.jms.common.Destination.checkDestinationType(Destination.java
:113)
at weblogic.jms.client.JMSSession.createBrowser(JMSSession.java:1516)
at weblogic.jms.client.JMSSession.createBrowser(JMSSession.java:1500)
at Test.run(Test.java:100)
at Test.main(Test.java:311)
Is there anyway for me to programatically distinguish between queues and topics
as there seems not to be any javadoc on weblogic.jms.common.Destination and instanceof
does not work? I would prefer not to rely on exceptions.
I'm using Weblogic 8.1 sp2.
Thanks
Riad
Cool. Thanks for your help Tom.

I'd like to know if a JMS client can create a topic or queue dynamically to be used by others JMS clients, or this is a operation which only can be performed by JMS server.
Thanks in advance.I should add that the JMS spec does define an API for creating 'temporary destinations', e.g., using the QueueSession.createTemporaryQueue() method. However these have a few limitations over standard destinations: firstly, they only survive for the lifetime of the connection from which they were created, when the connection is closed the destination is destroyed and the contents is lost; secondly, although producers from any connection can produce messages to a temporary destination, only consumers that belong to the same connection within which the temporary destination was created are able to consume from a given temporary destination. All that said, temporary destinations can often be useful, particularly for handling request/response type interactions - see QueueRequestors too for more info.

Request-Reply in JMSAdapter SOA 11g using a Topic and a Queue
Hi All
We are trying to implement JMS Request\Reply with Tibco EMS Server using JMS Request\Reply. Problem is that Tibco has exposed a topic (where request message has been enqueued) and replies the message is a pre defined JMS queue.
I am trying to use JMS adapter in SOA 11g (OSB doesnt support request\reply as soon as destination is selected as Topic ) with foreign JMS server setup in weblogic.
Problem is that when i invoke the composite, it errors out saying that request destination has to be a queue. I tried to find any sample that talks about request-reply with topics but could not find any.
Is request-reply pattern supported with topics or topic-queue combinations in JMS adapter 11g? Please let u know. ThanksHi All
The request-reply pattern is working with queues and topics, but not with topic and queue. The issue is with this:
<adapter-config name="RemoteOSBJMSService" adapter="JMS Adapter"
wsdlLocation="RemoteOSBJMSService.wsdl"
xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/JMS/RequestReplyTopic"
UIJmsProvider="WLSJMS" UiOperationMode="Asynchronous"
UIConnectionName="chdsez147855d"/>
<endpoint-activation portType="Reply_ptt" operation="Reply"
UITransmissionPrimitive="Request-response">
<activation-spec className="oracle.tip.adapter.jms.inbound.JmsConsumeActivationSpec">
<property name="PayloadType" value="TextMessage"/>
<property name="UseMessageListener" value="false"/>
<property name="DestinationName" value="jms.soa.local.response.q"/>
</activation-spec>
</endpoint-activation>
<endpoint-interaction portType="Request_ptt" operation="Request"
UITransmissionPrimitive="Request-response">
<interaction-spec className="oracle.tip.adapter.jms.outbound.JmsProduceInteractionSpec">
<property name="TimeToLive" value="0"/>
<property name="PayloadType" value="TextMessage"/>
<property name="DeliveryMode" value="Persistent"/>
<property name="DestinationName" value="jms.soa.local.request.topic"/>
</interaction-spec>
</endpoint-interaction>
</adapter-config>
The connection factory "eis/JMS/RequestReplyTopic" can either hold isTopic as false or true. If i set it to false, it doesnt even let me enqueue and if i set it to true. The reply doesnt arrive.

How to limit max number of downloads at once (and create a download queue)
I just "upgraded" to Mozilla 26.0 last night and was quite irritated that they changed the made it so that I cannot access the old download window. Was it really necessary to get rid of the work-around to get to the old download window?
Anyway, besides being more visually appealing, it previously downloaded two files at a time, unless I manually forced it to do more. The rest of the files would go into a download queue to wait their turn. After the update, it no longer creates a queue, leading to much slower downloads and it also slows my computer if I download too much.
Is there any way that I can limit the max number of downloads (unless I want to force it to download more) like I had on the previous version of firefox? I would prefer not to add more any add-ons, so if there is an check-box that I missed somewhere or something in about:config that would allow me to do this it would be better.
Also, is there any way to pause downloads now?Check these 2 articles

JMS destination and queue in jndi.properties
I am using activemq to create a very simple jms application.
But there is a point I have not understand.The administered connection factory object that I use is org.activemq.jndi.ActiveMQInitialContextFactory which is the ActiveMq specific object. Do I have to do the same with the destination object?I read that Destination is also an administered object so I have to use an object of the ActiveMq? Specifically in the jndi properties where I define the queue property the value must be:
1.an activeMq object
2.a java class that implements the javax.jsm.Queue interface
3.a physical name of another server?
and in the code where I look up the destination object
Destination destination = (Destination) jndiContext.lookup(queueProp);What exactly will be the queueProp? I would appreciate an example
Thanking you in advance.I've read the documentation but I am afraid I miss some points.
First of all I use the following code from an example in the net where the <b> activemq.jar is >/b> used and the jndi.properties is not used at all and the following code is working:package jms;
import org.activemq.ActiveMQConnectionFactory;

}But I want to make it work with jndi.properties.
So I am trying to use a code where connectionFactory and Destination are loaded from the jndi properties.After experimenting with code
the following is working
try {
connectionFactory = (ConnectionFactory) jndiContext.lookup("connectionFactory");
Destination destination = (Destination) jndiContext.lookup("QUEUE/MYQUEUE");
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);if only I go to the activeqm/bin folder and open the broker.If I did that in the previous code(with no jndi prop)
there was an exception that was saying that the port was already used.So I do not understand why in the one case opening broker is necessary for the connection and on the other hand it causes a problem.
Moreover in the case that I invoke broker from bin folder. In this case I would like to ask a question.The activemq.xml is necessary? If yes it is there where we define the queue?
If not where else apart from the jndi.properties do we define queue?
Please if is possible provide me with an example of the necessary places that we define a queue.
Thank you -
When do VI and queue references become invalid?
Hi all,
I have a fairly complicated problem, so please bear with me.
1) I have a reentrant SubVI (let's call it VI "Assign") that has an input cluster of (VI ref, queue ref) (let's call the cluster type "Refs"). If the VI ref is invalid (first execution), the VI ref and queue ref are assigned values and are passed on as an output cluster of same type. (The VI does other things too, but for simplicity only this is important.)
2) The VI that calls VI "Assign" (let's call it VI "Store") is not reentrant and has a local variable of type "Refs" that is wired to the input and output of VI "Assign". This VI effectively stores the references. The references returned by VI "Assign" are always valid right after the call, but after the problem condition described below, they are invalid at the start of all calls before they are passed to VI "Assign".
3) VI "Store" is called by multiple non-reentrant VIs, so the local variables of VI "Assign" retain their values (Has been tested and verified to retain their values). The VI causing the problem in this case is a template VI of which multiple copies are launched (let's call it VI "Template").
The problem is that the moment an instance of VI "Template" is closed, the queue reference becomes invalid, although the actual variant value of the reference remains the same. The VI ref can become invalid or not, depending on small changes, but is always reproducible. I assume there must be some similarity between VI and queue refs. After spending some time researching, the Labview help states for the Open VI Ref component "If you do not close this reference, it closes automatically after the top-level VI associated with this function executes." In this case I assumed it means that the moment the reentrant VI "Assign" finishes, the references will get cleared ?? So I made a non-reentrant VI (let's call it VI "NR Assign") that only assigns values to the references and VI "Assign" now calls this VI (It effectively does what I described VI "Assign" does). I keep this VI alive by using it in a VI which never terminates and since it never terminates, the references should never become invalid. Anyone still following? This didn't solve the problem though. If I reproduce the same scenario using only one instance of the template VI, it works just fine. Furthermore, the VI and queue references are never closed, to aid analysis of the problem. Can anyone shine some light on what happens when a template VI terminates? Could this be the problem?
Unfortunately I cannot include the code.
Thank you whoever is able to make sense of this.

All LabVIEW refnums do get deallocated automatically when the top-level VI in whose hierarchy the refnum was created goes idle (stops executing). You will have to make sure that the creation of a refnum is done inside a VI hierarchy that stays running for the entire time you want to use that refnum.

Hello Kappy - Thank you for persevering with my printer issues. Firstly, I use Firefox, recently updated & as yet have not discovered how to monitor downloads. The software for HP Laserjet 2200 was eventually automaticallly, and therefore correctly, installed.The Add Printer Pane accessed via the + button in the Printer & Scanner window is blank - the Name & Location and Print Using & Add areas are all grayed out, therefore I can't locate the printer driver even though it is in the Printer folder. I messed around with HP Direct Protocol & Line Daemon functions, entering my IP address, just to see if I could locate the printer driver - I could. However, I get a pop-up window which says 'Unable to verify the printer on your network' but it gives me the option of going ahead anyway, which I did. I was able to create a print queue, able to give a print command, the printer window opens, but the printer appears as 'busy', but of course it's not printing. To look at the issue from another perspective: previously I was running 10.5.8 on my old Power Mac G5 and a week before I shifted over the iMac I paused the printer but when tried to resume printing I got a pop-up message saying IPadmin > enter administrator name + password. Which of course I couldn't do - I discovered this was a bug afflicting10.5 & 10.6 operating systems; the only way I could get around it was by re-creating myself as a new administrator, which I did, and got the printer going again. So, if I have a "Network" printer perhaps there's another route to get the driver recognized... What do you think?

env.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");
jndiContext = new InitialContext();
queueConnectionFactory = (QueueConnectionFactory)jndiContext.lookup("QueueConnectionFactory");
queue = (Queue) jndiContext.lookup(queueName);
}catch (NamingException e) {
System.out.println("JNDI API lookup failed: " + e.toString());
System.exit(1);
try {
queueConnection = queueConnectionFactory.createQueueConnection();
queueSession = queueConnection.createQueueSession (false, Session.AUTO_ACKNOWLEDGE);
queueConnection.start();
queueSender = queueSession.createSender(queue);
requestMessage = queueSession.createTextMessage();
requestMessage.setText("does");
/* The code works fine till here , but below as soon as i say replyQueue = queueSession.createQueue("todo"); , it says the destination dosenot exist. why isnt it creating a temporary queue for me . Exception thrown is javax.jms.JMSException :
This Destination Does Not Exist.
replyQueue = queueSession.createQueue("todo");
Destination replyDestination = replyQueue;createTemporaryQueue() already creates a unique
destination; you don't need to do anything else.
Note as we discussed in the previous thread; you
should not create a temporary destination per
request; you should create 1 temporary destination
per consumer/process and reuse it across requests;
using a correlationID to match requests to
responses.

Hello Mr.James,
pleeeeeeeeeeeeeeease give me one example of how do i create only one temporary queue and differentiate resposes based on CorrelationID, i mean i am just not able to do it , i feel i will have to browse through entire queue matching for CorrelationId's, however u had earlier rejected this approach
THEN HOW DO I MATCH RESPONSES IN TEMPORARY QUEUES TO MY REQUESTS BASED ON CORRELATIONID , PLEASE GIVE ME AN EXAMPLE -
Can't create a print queue on OS 10.7 via HP driver installed by Apple
I've ust bought a reconditioned iMac and am getting applications up and running, but I'm unable to get my HP Laserjet 2200DN printer working. The Add Printer pane (Print & Scan Preferences) remains blank: Name & Location and Print Using & Add areas are all grayed out, therefore I can't locate the printer driver even though it has been installed in the Printer folder. I've messed around with HP Direct Protocol & Line Daemon functions, entering my IP address, just to see if the printer driver could be located - it could. However, I get a pop-up window which says 'Unable to verify the printer on your network' but it gives me the option of going ahead anyway, which I did. I was able to create a print queue, able to give a print command, the printer window opens, but the printer is 'busy', but of course it hasn't been given the command to print anything. Any ideas?
Alex CarMorning Alexander Carr,
Thanks for using Apple Support Communities.

Defining/Creating a JMS Queue in XI
Scenario: Third party system would post messages in XI Jms queue, the messages would ultimately be sent to SAP.
Need to create this JMS queue in XI which receives Jms messages from third party.
Steps done:
1) Defined Sender Communication Channel 'CC_JMS'
JNDILookup name:jmsfactory/default/QueueConnectionFactory
JMSQueue:jmsqueues/default/JMS_queue
initialcontextfactory:com.sap.engine.services.jndi.InitialContextFactoryImpl
JNDIServerAddress:<<serverIP>>:50004
2)Defined sender ID for the outbound interface in SXMSIF
3) Added job(I've given the name, is it right?) in SXMb_Adm and Defined message filter for that job. activated.
4)configured message filter for the above sender ID. Queue name XBT1
5)when checked in adapter monitor for JMS_queue.Shows the following error message
CC_JMS : Sender channel. Details: Object not found in lookup of JMS_Queue.
Questions:
1)Is that the right approach i am following
2)How do i assign CC_JMS to JMS_queue
3)How do i know if JMS_queue is up and running
thnx
