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.

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
raghuHi 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.

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 -
[WLST offline]: Cannot create distributed destination
We have a small problem with WLST and distributed destinations. I have made the following code:
readDomain ('< our domain path >/Demo8')
# Check that the queue exists
ls ('/JMSServer/cgJMSServer1/JMSQueue')
create ('myQueue1','JMSDistributedQueue')
cd ('JMSDistributedQueue')
cd ('myQueue1')
set ('JNDIName','myjndi')
create ('member1','JMSDistributedQueueMember')
cd ('JMSDistributedQueueMember')
cd ('member1')
set ('JMSQueue','queue1')
cd ('..')
cd ('..')
UpdateDomain()
The problems is, that the command "set ('JMSQueue','queue1')" fails.
Does anyone have an example of a successful WLST configuration of Distributed Destinations?
The error message from my script is:
Error: setJMSQueue() failed.
Error: set() failed.
Traceback (innermost last):
File "scr.py", line 19, in ?

ception(CommandExceptionHandler.java:33)
Your help will really be appreciated....
Kind regards,
HenrikThe best way to create distributed destinations is to create physical destinations in single server mode and then create more servers and a cluster. wlst offline will automatically create distribued destinations and members. Considering that the recommended JMS architecture is homogeneous, there is little need to do it manually. An example:
readTemplate('c:/bea813/weblogic81/common/templates/domains/medrec.jar')
cd('JMSServer/MedRecJMSServer')
q=create('newQueue', 'JMSQueue')
q.setJNDIName('newQueue')
cd('/')
create('newServer1', 'Server')
create('newServer2', 'Server')
create('newCluster', 'Cluster')
assign('Server', 'newServer1,newServer2', 'Cluster', 'newCluster')
writeDomain('d:/temp/domains/813/medrec/medrec_0720')
closeTemplate(); -
Can I create a new Queue/Topic in client application?
In sun's JMS turorial the application client sends messages to the queue, which is created administratively, using the j2eeadmin command. Can I create a new destination(queue or topic) in my client's code?
Thanks very much.Thank you very much, flhood. This is my first time to gain aid from website except my school's BBS.
But I still cann't solve the problem, here is my code, can you help me to check it if there is anywhere that I might do wrong?( I omit the try/catch part)
QueueConnectionFactory queueConnectionFactory =null;
QueueConnection queueConnection =null;
QueueSession queueSession =null;
Queue queue =null;
Queue tempQueue =null;
QueueSender queueSender =null;
TextMessage message =null;
final int NUM_MSGS;
Context jndiContext =null;
jndiContext =new InitialContext();
queueConnectionFactory =(QueueConnectionFactory)jndiContext.lookup("QueueConnectionFactory");
queueConnection =queueConnectionFactory.createQueueConnection();
queueSession =queueConnection.createQueueSession(false,Session.AUTO_ACKNOWLEDGE);
queueConnection.start();
queue =queueSession.createQueue("MyQueue");
tempQueue =queueSession.createTemporaryQueue();(Actually I don't know why I shall need a tempQueue if I have the queue.)
queueSender =queueSession.createSender(queue);
message =queueSession.createTextMessage();
NUM_MSGS=10;
for (int i =0;i <NUM_MSGS;i++){
message.setText("This is message "+(i +1));
System.out.println("Sending message:"+message.getText());
queueSender.send(message);
These codes run well if I lookup in the JNDI for the existing queue "MyQueue", but when I try to make it dynamically, the resutlt shows(I only use texteditor+j2sdk1.4+j2ee1.3.1):
Java(TM) Message Service 1.0.2 Reference Implementation (build b14)
Sending message:This is message 1
Exception occurred:javax.jms.InvalidDestinationException: No Destination found f
or name: MyQueue
I use deloytool to check the destionation, of course the "MyQueue" hasn't been created, but I use try/catch to brace these two line:
queue =queueSession.createQueue("MyQueue");
queueSender =queueSession.createSender(queue);
Nothing gain.
They are really puzzling me! -
Problem creating Physical Destination for Message Driven Bean example
I am trying to create a MDB application. in which i want to distribute the workload using messages.
I am using SUN j2ee application server8.2 and netbeans 6.5 on windows xp professional.
I referred the j2ee 1.4 tutorial to create the mdb's.
I am able to create queue's and connection factories.
the tutorial says
To create the physical destination, perform the following steps:
.In the tree component, expand the Resources node, then expand the JMS Resources node.
.Select the Physical Destinations node.
.On the Physical Destinations page, click New. The Create Physical Destination page appears.
.In the Physical Destination Name field, type PhysicalQueue.
.Choose queue from the Type combo box.
.Click OK.
but i am not able to find out this Physical Destination node in admin console. So when i execute my MDB project the messages are created but the onMessage() method is not invoked.
Please help!!!Hi,
but this example was in guide to this version.
Ok, in case it is not possible to use MDB, how should i handle long time consumpting functions in EP enviroment?
(customer has only EP6SP2 and he need to send a lot of mails after user request and i dont want to leave user waiting till that function ends. - should i start new thread in portal?)

Create Distributed Destination
I want to automate creation of distributed destinations as at times I need to create around 40 of them. Currently I do it "by hand" which is not very effecient !
I tried using ant but it has too many limitations (does not allow space in the name etc). I tried WLST and can create JMSQueues but simply cannot create Distributed Destinations. I have searched and searched the web for all possible scripts, and tried all of them, but none of them work.
My environment uses WebLogic 8.1 SP3 and above. I will be creating the Distributed Destinations on an existing (running) domain.
If someone has already got this to work, please pass on the information to me.
Thanks,
Kevin.An example is given here: http://middlewaremagic.com/weblogic/?p=7188
excerpt from the complete script
print 'CREATE UNIFORM DISTRIBUTED QUEUE';
resource.createUniformDistributedQueue('DistributedQueue');
distributedqueue = resource.lookupUniformDistributedQueue('DistributedQueue');
distributedqueue.setJNDIName('jms/CompanyQueue');
distributedqueue.setLoadBalancingPolicy('Round-Robin');
distributedqueue.setSubDeploymentName('SubDeployment');
distributedqueue.setUnitOfOrderRouting('PathService');When you want to create scripts you can also first use the admin console. In the middle top there is a record button.
To create a script, hit the record button, do some configuring, and hit the record button again. To script is
saved in the ${DOMAIN_HOME} directory. -
How to create a JMS queue linked to external (remote) JMS server?
Hello,
I'm trying to receive messages from a remote JMS queue. I found some information on the Internet on how to create an external JNDI resource (my remote JMS queue connection factory is bound to LDAP context on remote box). I was able to configure JNDI resource that points to remote queue connection factory, but I don't know what to do next.
How can I create a local JMS destination (queue) that will be the image of the remote queue? At least I'm guessing this is what needs to be done in order to deploy MDBs.
I would appreciate it if someone could tell me how to get this working. Maybe the steps I took were not in the right direction - the bottom line is that JMS queue and queue connection factory are deployed on a remote server, and I need to get messages sent to them on the local server. I'm using Sun App Server from J2EE 1.4.
Thank you,
MarkPlease refer to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6377822, particularly the evaluation. Could your situation be the same too (i.e server ip address changing dynamically)? Also, which OS are you using and do you have any firewalls setup that prevents access to port 3700?

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?

Pdfmark code in MS Word 2008 doc doesn't seem to work properly to create Named Destination
Hi all,
I've been having trouble with creating Preview-compatible Named Destinations in Acrobat 9.x (see http://forums.adobe.com/thread/770470?tstart=0). Distiller, on the other hand, appears to create compatible Destinations, so as a last-ditch effort, I tried to go back to my original source file (Microsoft Word 2008 document) to use Distiller's pdfmark functionality, to see if maybe I could finally get a PDF with Preview-compatible Destinations.
Following instructions found elsewhere on this forum, I went into Word and inserted the following field into a test location in my document:
PRINT "[ /Dest /testdest /View [ /XYZ null null null ] /DEST pdfmark"
This field code is supposed to then cause a pdfmark to be inserted into the resulting PostScript and/or PDF files. Distiller is supposed to understand this and turn it into a Named Destination called "testdest." However, it doesn't seem to work - I don't see the pdfmark code in the PS file, and the PDF file doesn't have any Named Destinations in it.
I'm using Acrobat 9.x on Mac OS X 10.6.5, so I tried this two different ways:
1) Using the "Print to Adobe PDF" workflow (which replaced the "Adobe PDF Printer" from previous OS/Acrobat versions) - this automatically generates a PDF via (presumably) an API call to Distiller... and
2) Using the "Print to Postscript" workflow to generate a PS file, which I then ran through Adobe Distiller.
In neither case did I end up with a named destination in the PDF file, as I was supposed to. In case #2, even the Postscript file didn't have a pdfmark embedded in it. Thus, I'm assuming that perhaps this is particular issue may be a problem with MS Word 2008 rather than with Acrobat... but I'm hoping someone might have a clue as to how to fix it.
I welcome ideas on how to get Word 2008 to properly output pdfmark code, so that Distiller will pick it up and properly embed a Named Destination into the PDF...
Thanks in advance.
(If anyone has ideas about the Preview-compatible problem, linked above, that would also be great!)You're suggesting that it was never fixed from Word 2004 to 2008? Possibly. I wonder if it's fixed in Word 2011? Anyone know? But is it really a Word problem, rather than a Distiller issue?
I appreciate your offer, though I do have access to Word on Windows (2003, I think), so I could try Distilling there... I only worry about formatting, since there are minor differences (e.g. font kerning, etc.) between Mac and Windows that are subtle, but sufficient to create formatting issues for very long documents (e.g. pushing figures onto the wrong pages, etc.). That would be a rather big problem.
The question remains whether this is an issue with Word or Distiller, though... and whether it's fixed in Distiller X and/or Word 2011.
Adobe, care to comment?
I'd really love to find a proper Mac solution, if one exists... it would be rather a slap to Mac users if a solution doesn't exist. -

Best practice for creating RFC destination entries for 3rd parties(Biztalk)
Hi,
We are on SAP ECC 6 and we have been creating multiple RFC destination entries for the external 3rd party applications such as Biz-talk and others using TCP/IP connection type and sharing the programid.
The RFC connections with IDOC as data flow have been made using Synchronous mode for time critical ones(few) and majority through asynchronous mode for others. The RFC destination entries have been created for many interfaces which have unique RFC destinations with its corresponding ports defined in SAP.
We have both inbound and outbound connectivity.with the large number of RFC destinations being added we wanted to review the same. We wanted to check with others who had encountered similar situation and were keen to learn their experiences.
We also wanted to know if there are any best practices to optimise on number of RFC destinations.
Here were a few suggestions we had in mind to tackle the same.
1. Create unique RFC destinations for every port defined in SAP for external applications as Biztalk for as many connections. ( This would mean one for inbound, one for outbound)
2. Create one single RFC destination entry for the external host/application and the external application receiving the idoc control record to interpret what action to perform at its end.
3. Create RFC destinations based on the modules it links with such as materials management, sales and distribution, warehouse management. This would ensure we can limit the number of RFC to be created and make it simple to understand the flow of data.
I have done checks on SAP best practices website, sap oss notes and help pages but could not get specific information I was after.
I do understand we can have as unlimited number of RFC destinations and maximum connections using appropriate profile parameters for gateway, RFC, client connections, additional app servers.
I would appreciate if you can suggest the best architecture or practice to achieve RFC destinations in an optimized manner.
Thanks in advance
SamNot easy to give a perfect answer
1. Create unique RFC destinations for every port defined in SAP for external applications as Biztalk for as many connections. ( This would mean one for inbound, one for outbound)
-> be careful if you have multi cllients ( for example in acceptance) RFC's are client independ but ports are not! you could run in to trouble
2. Create one single RFC destination entry for the external host/application and the external application receiving the idoc control record to interpret what action to perform at its end.
-> could be the best solution... its easier to create partner profiles and the control record will contain the correct partner.
3. Create RFC destinations based on the modules it links with such as materials management, sales and distribution, warehouse management. This would ensure we can limit the number of RFC to be created and make it simple to understand the flow of data.
-> consider this option 2.
We send to you messagebroker with 1 RFC destination , sending multiple idoctypes, different partners , different ports.
