OT: Subscribing to topic

Sorry for the off-topic thread, but I'd like to be able to subscribe to topics as explained in the
read subscriptions page:
You can subscribe to either an entire forum or to individual topics by clicking on the Subscribe link in the gray box at the top of each forum or topic thread.
Please note that I'm not referring to the "Subscribe to this discussion by email" option. Your help is appreciated.

Expiration of messages in JMSTopics / Queue Subscription to topics.

Hi all,
I tried to use topics in one of my OSB flows.
i have 2 doubts in this regard.
1. Is there a way in with i can subscribe my JMS queues to JMS topics?
2. If in my OSB flow i subscribe directly to the topic(instead of my queue subscribing to topic and my OSB flow subscibing to queue), even after my flow has taken the message from the topic, the message is still retained in the topic. How do i get rid of these retained messages in the queue dynamically. I dont want to delete those messages manually.

I'm not familiar with OSB particulars (this is a JMS forum -- OSB has its forum), but I can try answer your questions with respect to WL JMS only.
1. There's no direct facility at the WebLogic Server layer for subscribing a queue to a topic. The standard approaches are to write a basic MDB for the purpose, or configure a Messaging Bridge.
2. Are the messages in the subscription getting deleted? If not, then the problem is either in your app or at the OSB layer (failure to acknowledge/commit received messages). If so, then messages are likely accumulating in another subscription -- you can check for other subscriptions on the console, and keep in mind that distributed topics implicitly create subscriptions for forwarding messages between members. As you know, a message that is sent to a topic must be acknowledged/filtered-out/committed by all subscriptions before it is fully deleted.
It would be interesting to know the details about your use case, as I suspect it is a fairly common one. In particular, why do want to subscribe a queue to a topic subscription in the first place? I can then forward your write-up to OSB and JMS Product Managers, which might help accelerate the release of certain features on our roadmap. (email tom . barnes at oracle . com)

Dynamic subscription of Topic "jmstopic/default/BPMMailsTopic"

Hi guys,
is it possible to subscribe a topic during the runtime (dynamically)?
I'm working with: SAP NetWeaver 7.3 (Java), JDK 1.6, NWDS 7.3 SP03.
In my coding, I'm using a Message Driven Bean with annotation to the BPMMailsTopic you can find under "SAP NetWeaver (Administration) --> Configuration --> Infrastructure --> JMS Server configuration --> jmstopic/default/BPMMailsTopic. On that topic, a component is defined, but no (durable) subscribers.
Many thanks and regards,
Cengiz

Marc,
I think I see what you're trying to do. You'll have to separate process that renders the LOV as a series of check boxes from the process that sets the checked values for each user.
Before the LOV is rendered on a page, make sure you set the session state value of the LOV item to a colon separated set of IDs based on your query:
SELECT mesg_id
FROM subscriptions
WHERE upper(network_id) = upper(:APP_USER)
If you have trouble, let me know, I'll try to come up with an example.

Subscriber not receiving published message

Hi,
I'm new to JMS and hence might sound very novice..
I'm trying to send and receive messages between 2 servers running App Server 7.0
I've configured both of them to not start the built in JMS service (I tried using that initially, did not work).
So, I start the imq broker on each server manually before I start the application on each of them.
I can see thru my debug statements that my client is publishing the message, but its not received by the subscriber.
I have the imqbrokerhostname set on each server (thru the app server admin console) to point to each of them.
Here is how I have written my publisher and subscriber.
The publisher is just another class and the subscriber is a thread that gets created when the app starts (I'm sure about that, as I have debug statements to prove that).
Here is my publisher code:
public void refreshRDMTable(String strTableName)
//Establish error logging category
Category m_category = Category.getInstance("JMS_eCATSPublisher.refreshRDMTable");
m_category.info("entering");
String strMessage = strTableName;
String topicCFName = Foundation.getProperty("eCATSTopicConnectionFactory");
String topicName = Foundation.getProperty("eCATSTopic");
try
InitialContext context = new InitialContext();
// Lookup the topic connection factory
// from the initial context.
TopicConnectionFactory tcf = (TopicConnectionFactory) context.lookup(topicCFName);
// Create a new topic connection from the topic
// connection factory.
TopicConnection conn = tcf.createTopicConnection();
// Start the connection
conn.start();
// Create a new topic session from the topic
// connection. The session should not be transacted
// and should use automatic message acknowledgement.
TopicSession session = conn.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
// Lookup the topic that we are to publish to
// from the initial context.
Topic topic = (Topic) context.lookup(topicName);
// Create a new topic publisher using
// the topic session. The publisher should
// be created to publish to Topic topic.
TopicPublisher publisher = session.createPublisher(topic);
// Using the topic session create a new
// text message to publish
TextMessage message = session.createTextMessage(strMessage);
// Using the publisher publish the text
// message that's just been created
publisher.publish(message);
m_category.info("Publishing JMS message: " + message);
catch (NamingException ne)
ne.printStackTrace();
catch (JMSException jmse)
Exception linkedException = jmse.getLinkedException();
if (linkedException != null)
linkedException.printStackTrace();
jmse.printStackTrace();
}//end method
and Here is my subscriber class:
public class JMSSubscriberThread extends Thread {
private boolean isStopped;
private TopicConnection fTopicConnecton;
private TopicSession fSession;
private boolean trueVal = true;
private Topic fTopic;
public void run()
Category cat = Category.getInstance("JMSSubscriberThread.run");
String topicCFName = Foundation.getProperty("eCATSTopicConnectionFactory");
String topicName = Foundation.getProperty("eCATSTopic");
int receiveTime = Integer.parseInt(Foundation.getProperty("callReceiveTimerMillisec"));
JMSRefreshObject rdmRefreshThread = new JMSRefreshObject();
cat.info("entering");
TopicSubscriber m_Subscriber = null;
try
final InitialContext context = new InitialContext();
// Lookup the topic connection factory
// from the initial context.
TopicConnectionFactory tcf =
(TopicConnectionFactory) context.lookup(topicCFName);
// Create a new topic connection from the topic
// connection factory.
fTopicConnecton = tcf.createTopicConnection();
// Create a new topic session from the topic
// connection. The session should not be transacted
// and should use automatic message acknowledgement.
fSession =
fTopicConnecton.createTopicSession(
false,
Session.AUTO_ACKNOWLEDGE);
// Lookup the topic that we are to subscribe to
// from the initial context.
fTopic = (Topic) context.lookup(topicName);
// Create a new topic subscriber using
// the topic session. The subscriber should
// be created to subscribe to Topic topic.
m_Subscriber = fSession.createSubscriber(fTopic);
fTopicConnecton.start();
catch (NamingException e1)
cat.error(e1.getMessage(), e1);
catch (JMSException e1)
cat.error(e1.getMessage(), e1);
do
try
// Using the subscriber check for published
// messages. Use the subscriber's receive()
// method as we are not sure when a message
// will be published to the topic.
TextMessage message;
message = (TextMessage)m_Subscriber.receive(receiveTime);
if(message != null)
cat.info("Message=========="+message.getText());
rdmRefreshThread.refreshRDMTable(message.getText());
catch (JMSException e)
cat.error(e.getMessage(), e);
} while (isStopped == false);
try
fTopicConnecton.close();
catch (JMSException e)
cat.error(e.getMessage(), e);
}//end method
public void stopExecution()
this.isStopped = true;
} //end method
} //end class

It looks like it is accepting something, but for some reason the message is still not received.
Please advice appropriately.

[Given up] How do you get 'show new forum topics'?

There is 'Show recent posts', but I'm interested in *topics*. Any ideas? Am I missing sth?
Edit:
The way I do it is rather unDijkstraish, but I'm stupid and lazy and it works for me. I simply bookmark the newest topic f.e.
http://bbs.archlinux.org/viewtopic.php?id=85300
and next time I want to check the forums for some new topics, I enter the next urls manually
http://bbs.archlinux.org/viewtopic.php?id=85301
http://bbs.archlinux.org/viewtopic.php?id=85302
etc.
I subscribe to topics I find interesting and skip the rest.
When I get a page that says "Bad request. The link you followed is incorrect or outdated." I bookmark it and remove the previous one (http://bbs.archlinux.org/viewtopic.php?id=85300 in the above example).
Lather, rinse, repeat.

Um, not quite. By "new" I mean "the ones I haven't seen yet", so 'Show unanswered posts' != 'Show new *topics*'.
I want to know what's going on on the forums, did sb posted sth interesting or maybe I can help sb. I've read all the topics (the 'titles') and subscribed to some of them.
Now I'd like to be notified about new *topics* only, because the old ones I have already sorted out: either I'm interested in the discussion and subscribed or I'm uninterested and would like to have a way to disregard them automagically.
The search function is of not much help here.

Queus versus Topics Question

I apologize for asking such a mundane question, but I'm new to JMS and want to make sure I have the right approach before I dive into it (so that I don't get part way and realize my initial assumptions were erroneous).
Here is the story. I have a process, let's call it Originator, that is going to create a JMS message and I have two consumers of the message, Consumer1 and Consumer2. The thing is that it is critical for Consumer1 to receive the message. In that case, I'm really using JMS as interprocess communication from Originator to Consumer1. Consumer2, on the other hand, is informational, for simplicity, let's say it's for logging. Originator does not care that Consumer2 actually receives the messages since it is not part of the critical path.
So I have this quandy. Though I have limited experience with JMS, I've always thought of queues as proper when dealing with communication between processes, and topics as a way to post information for anyone interested.
It seems like I have two choices here...
1) I can just use a topic and have both Consumer1 and Consumer2 subscribe to it. However, I get an uneasy feeling about this approach because it treats cricital interprocess data like an FYI. Maybe I have this wrong in my mind. I don't know. How will Originator know that Consumer1 has received a messages posted to a topic?
2) I could have a queue and a topic and send the message to Consumer1 via the queue, then post the same message to the topic. This allows for as many subscribers as want to be informed to get the message on the topic, but also provides direct, confirmable comms to Consumer1. It has the disadvantage of having to create and manage two distinct resources for one message.
I'd appreciate your advice on this issue. Do I have too narrow of a view on topics?
Thanks,
Mike.

It sounds like topics are what you'll want to use. If you use a durable subscriber (durable topic subscirbers basically behave like queues) for Consumer1 and a non durable subscriber for Consumer2 and have the Originator (publisher) send persistant messages you should get the quality of service you need. Both consumers will recieve the messages but Consumer1 will have a higher level of service becuase if it is not online the messages will be queued up for it.

Is it possible to keep the "Email me when someone replies" checkbox AFTER you make a posting?

I'm not sure if I'm the only who does this, but sometimes I forget to check off this box before submitting a new post (i.e, starting a new message thread). Currently, this feature disappears after you submit a new message thread. It is real useful feature to have, and without it, makes your posting experience a lot less desirable.
Is it technically possible to keep the check-off box available at all times during a posted thread?

Hi SteveCT99,
It is possible to automatically subscribe to topics you participate in:
At the top of the page, click on the "My Settings" link, located after the "Sign Out" link by your name in the grey box.
Click on the "Subscriptions and Bookmarks" tab
Check box after "Notify me for my own posts and replies"
- and/or -
Check box after "Automatically subscribe me to topics I participate in" to add the topics to your subscription list.
Scroll down and Save changes
You should now automatically get notices each time a new reply is added to the topic.
Please let me know if this helps.
Thanks,
SunshineF

Calling a method on all replicas of a bean in one shot

          Hi,
          Is there any properties by which one can make a replica aware stub direct a method call to all
          instances of the bean in a cluster? The requirement is to update data cached in all instances
          of a bean in the cluster by invoking a method on all instances of the bean.
          Regards,
          Sreeja


          You can try to think about the issue in another way.
          Hope this link can help you.
          http://www.weblogic.com/docs51/classdocs/API_jndi.html#exactlyOnce
          If you do want to do it in your way.
          Try to use JMS Topic. One server can send a topic of updating and all other servers subscribe this topic.
          Good luck.

Error message when downloading music after purchase

I've never had a problem downloading songs from itunes before. I just purchased 3 songs and now, it gives me an error message saying that there is an error and the files are corrupted. When I try to "check for purchases", they are there, but will not download. Can anyone help me with this? Please email me directly since I'm a dummy when it comes to figuring out these forums. [email protected] Thanks.

Presuming you're using the latest version of iTunes, I'd suggest that you contact the iTunes Store customer support department through the form at the bottom of their web page and explain the problem to them. They may need to reset the download, or there may be a problem with the tracks themselves.
If you want to be emailed with replies to your questions when you start a topic, click on My Settings on the right of any of these pages, and click "yes" to "always subscribe to topics I create". Then any replies will automatically be emailed to you.
Good luck.

Restricting azure service bus access to certain IP range

I am using service bus from two cloud services WebRoleC1 and WorkerRoleC2.
on pushes some data and other received data by subscribing to topics.
Every application maintains the service bus connection details in its web/cloud config. Everything works fine.
I have multiple instance running of the same application for different customers , people make confusion while deploying and Put wrong connection details in say WorkerRoleC2 so it connects to Service bus of another customer.
I want to put restriction on service bus SB1 that only WebRoleC1 and WorkerRoleC2 can connect to it. If WorkerRoleC3 has the proper key then also connection should fail.
This also prevents people from attacking service bus if now public ip.
I don't want service bus to publicly exposed.
Thanks,
Subodh

Service Bus does allow you to restrict receive access to specific subscriptions. You can set credentials such that a client 1 can receive messages from a specific subscription whereas a client 2 cannot.

Mobile version of community

Hi Everyone
I am pleased to announce that based on the feedback we got from community members we have decided to reinstate the mobile version of the community. So you can now access the forums on the move again!
It is important to remember that the mobile version does not provide all the forums’ features and functionality, but it is a scaled- down mobile-optimised version. This will allow you to access the community and perform key tasks on the move, such as reading, creating and replying to posts.
See below for our Frequently Asked Questions about the mobile version of the community.
Thx
Kerry
Frequently Asked Questions for accessing the community on a mobile device:
How do I access the community on my mobile device?
You should use the same URL you use to access the main community – www.bt.com/community
What devices can I use to access the community?
You can use any mobile device to access the community, but the user experience is optimised on devices which use a WebKit browser, including AppleWebKit for iPhone and Android, S60 Webkit for Nokia, and IE Mobile for HTC. To optimise the mobile experience on Blackberry and other devices, Opera Mini can be downloaded, which will enhance the way the community looks on your device. Further details on device compatibility and suggested browsers is included at the end of this FAQ message.
What tasks can I complete on the mobile version?
The mobile version is intended to keep you up to date with the community when you are on the move. This means that key functionality is available, but you cannot perform all functions that are available on the main site. Key tasks you can complete are as follows:
Sign in/out of community
View boards, threads, and messages
Create new thread
Reply to existing threads
Mark messages as read/unread
Give ratings
Send and receive private messages
Search the community
Follow other members (add to friends); See who is following you
Change certain mobile settings:
Turn on/off private messages
Subscribe to topics I post to
Create a mobile specific signature
View your profile
View existing bookmarks
Link back to main bt.com site and Help site
Why can’t I do everything on the mobile version as I would on the desktop version?
The mobile version is intended for ‘on the move’, easy access to key functionality of the community. Access on a mobile device needs to be quick to load and easy to read on small screens, so we have removed some of the extra features and functionality you normally see on the main site in order to achieve this. For example, the modules you see on the right hand side of the main site such as ‘top rated posts’ are not available on the mobile version as there is not enough space on the screen.
How does it work? If I post on the mobile version will it update on the main site?
Yes – the mobile version links directly into the main community site so any posts, replies, and PMs that you send will automatically be updated on the main site.
Do you plan to add any more functionality to the mobile version in future?
There are no immediate plans to add any further functionality than what exists in the current version. However, we are always looking to make improvements to any services we offer so if you have specific feedback on additional functionality you would like to see on the mobile version, please send me a PM.
What should I do if I have any problems using the mobile version?
If you have any problems using the mobile version we would recommend posting your query in the Forum Guidance and Ideas board when you’re with your PC so other members can give support and advice. The moderator team can also respond here if needed.
How secure is my data?
User details are stored securely and encrypted in the community system. The mobile version of the community is subject to the same tests as the rest of the community site and was implemented using the same security best practices. Members are reminded that they can control what profile information is viewable by others via their user settings.

How to reimport music in IPOD back to ITUNES after computer has crashed?

i know this question has been asked before, and i have followed the instructions 'macmuse' posted. however, when i plug my ipod into the USB port, my computer does not recognize it as an IPOD it only shows up as an external drive. when i click on it, my computer asks me if i want to reformat the IPOD so that it can recognize it. has anyone else had this problem? i don't know how else to get my songs back on my computer if my computer cannot recognize/work with the IPOD when i plug it in. i have downloaded all necessary programs on my computer, and the IPOD is brand new - perhaps the old way of reimporting music no longer works? please help, i'd so appreciate any input!

A search on google will probably find utiltities that can be used to copy music off an iPod and onto a computer - after you've done it you then just need to do File > Add Folder to Library in iTunes (but I would advise maintaining a backup on an external drive from now on). This fairly old thread mentions some utilities that were around at the time the message was written http://discussions.apple.com/message.jspa?messageID=9990366#9990366
In terms of getting notifications, if you go into 'My Subscriptions' on the right you should get options to 'Always subscribe to topics I create' and 'Always subscribe to topics I reply to' - selecting the first should get what you want (though I've never tried it).

Can't see partition option or button on Disk Utility

I just bought a 500G backup hard drive for 2 computers. I want to partition it into separate portions for each computer and possibly a third smaller portion for my portable drive.
My problem is that using Disk Utility v10.5.6 running on OS 10.4.9 I cannot anywhere see a button or pulldown menu item that will allow me to create partitions as directed in the Disk Utility help files. I've searched for information in apple.com and can only find articles identical to what I see in my help file. Am I missing something obvious? I know about partitioning, but have never actually done it before.
btw- my external backup drive is "My Book" with Retrospect 6.1 software. However I haven't started up the software to do a backup yet because I wanted to partition the disk first. Any ideas, help, advice?!?!?
This is my first use of this forum. Must I visit the webpage often, or will the replies post to my email address as well as this webpage? Thanks! dsimmonsusc

Hi dsimmonsusc
Welcome to the forums!
For your first question, does the hard drive appear at all in the left hand pane of Disk Utility? Make sure you select the top level of the hard drive, and not any existing partitions inside it. For example, on my Powerbook, I see the following:
55.9 GB HTS72606M9 ...
Macintosh HD
I have to select the "55.9GB..." level to see the Partition tab, which will appear between "Erase" and "RAID" in the right-hand pane. It sounds like "My Book" will be the equiivalent of "Macintosh HD", so you need to select the level above that.
About forum replies, you can set the preference yourself - go to My Settings in the sidebar to the right, scroll to the bottom, and you should see the default settings - "Always subscribe to topics I create" and "Send subsccription emails immediately". Change these if you like, but as they are, you'll get a new email whenever someone responds (like this one)! But you will have to click the link in the email and go to the site to view the reply.

Not working: Send subscription emails: Once per day?

Seasons Greetings,
Can someone please clarify/confirm what I should have in My Settings in Subscription Preferences.
They are currently:
Always subscribe to topics I create: Yes
Always subscribe to topics I reply to: Yes
Send subscription emails: Once per day
It's the last option that doesn't seem to work for me. Yesterday after spending a bit of time helping out all the new nano owners I opened Mail and has 67 posts yesterday, with 25 today so far.

I have some with more than 5 but I don't want to bore you too much
What I really expected with 'Send subscription emails: Once per day' was a digest listing all replies to all posts for a 24 hour period.
Have I misunderstood or is something wrong?
