Tom !!! Help needed in JMS Topic Lookup Cluster DOMAIN

Hi Tom,
          We have a clustered domain with 2 managed servers and our application is an Applet-Servlet based application.We user JMS Topic for some of online blotters.
          And on looking up we get the following error,
          weblogic.jms.common.JMSException: <055053> <java.rmi.RemoteException: CORBA INTERNAL 1398079712 Maybe; nested exception is: org.omg.CORBA.INTERNAL: vmcid: SUN minor code: 224 completed: Maybe >
          weblogic.jms.client.JMSConnectionFactory.setupJMSConnection(JMSConnectionFactory.java:272)at weblogic.jms.client.JMSConnectionFactory.createConnectionInternal(JMSConnectionFactory.java:299)at weblogic.jms.client.JMSConnectionFactory.createTopicConnection(JMSConnectionFactory.java:198)at
          Pls note while looking up for the Initial context since it is a cluster environment, we look up using comma separated Ipaddresses.
          Pls note, we use JRE 1.4.2_13 for the applet to launch,.
          Earlier also for JMS failover i sought your help and your suggestions have really invaluable.
          Request you to provide me some more suggestions on this issue as well.
          Regards
          Suresh

The exception is thrown by the JVM's built in Sun IIOP (CORBA) libraries. I don't know the cause, but a google search for "SUN minor code: 224 completed: Maybe" yields a single hit that might help. See the July 23/24 posts for "Re: iiop: error with bidirectional connections" in the weblogic rmi-iiop newsgroup:

Tom Help needed in JMS Clustering!!!!!!!!!

Hi Tom,
          I have a typical problem with JMS Clustering,i amtrying to implement an automatic failover by registering the connection and the session with the exception listener and then inside onexception method i have reconnect logic.
          My application has an applet and the downloading page directly loads the MyApplet jar and weblogic thin client jars and then when i switch of the server using in CTRl-C in windows environment with a single server onException gets fired.Now for clustering we have moved to enterprise archive setup(.ear) and my applet jar and thinclient jars are bundled with in the war(web archive) and the war is inside the ear.In this scenario when i shut down one of the managed servers the onexception does not get invoked and then i shut down both the servers then also its not getting invoked, plz help me i dont understand what is wrong with this,when the servers are on onMessage works fine and my real time blotters also get updated.
          My clustering set up has 2 managed servers,2 JMS servers targeted to each managed server and a distributed topic.
          In a noraml scenario when the servers are running my onMessage gets called, but when i shutdown the servers the onException does not get called from the EAR.
          Pls help me on how to proceed.i cant put the thick weblogic.jar as down loading from my applet cannot handle it.
          Regards,
          Suresh

Sorry Suresh -
          I don't know what is going wrong - my suspicion is that you've found a bug in WebLogic thin-client IIOP.
          Since the problem started when you moved to SP5, you can try continuing to use the SP4 jar on the client.
          And sometimes this type of problem is with with Sun JDK libraries (which supplies most of the thin client IIOP stack), so there's a small chance switching to a 1.5JVM for the client would work (I don't know if BEA supports this).
          You might also try posting to the rmi-iiop newsgroup. (Andy just loves it when I push problems off to him! Well maybe not.)

Tom Help needed again!!!!!!!!JMS Failure Applet

Hi Tom,
          In my application applet is basically the client and it basically does the following
          1)Creates an initial context with the provider url
          2)Looks up for the Topic connection factory
          3)Then using the TopicConnection Factory creates the Topic
          Now the problem is in some of the PC's it gives the following error. at the first step while creating the initial context,pls note that the provider url is correct and we use http protocol with http tunneling enabled.
          javax.naming.NamingException: Couldn't connect to any host [Root exception is org.omg.CORBA.COMM_FAILURE:   vmcid: SUN minor code: 201 completed: No]

          occurring.Pls note that my applet is a signed one, and the network does not have any firewall
          My query is do we have to place this .java.policy file in every client machine and why is that it is not working in all the machine where the above mentioned error is coming.
          Pls help me in solving this problem.
          Pls also note that we have admin rights also on all these machines.

I don't know the answer. The best I can think of is to read the JMS applet white-paper if you haven't already:

Help needed on JMS queues

I am using Soa Suite 10.1.35 and trying to make a ESB integration work.
The requirement is I have to de-queue some data from a JMS queue and invoke a Oracle Pl/SQL Api(DB adapter) using the data in an ESB project.
I want it part of a single transaction, i.e. if the call to oracle API(db adapter ) fails( say db is down or api is invalid), i want the queue de-queue transaction to be rolled back as well.
I have made the routing service as synchronous. I have marked istransacted ="true" connection factory in oc4j-ra.xml file and auto_commit =>false for the Queue table, queue creation.
Still if the DB transaction fails the queue is not rolled back.
Any help or pointers will be greatly appreciated.
Please let me know if you require any information.

I tried compling servlet, but it is raising error
that coul not find package javax.servletWhat I did not mention... you need to add those JARs in the Classpath explicitly. You will find them in %TOMCAT_HOME%\common\lib. You atleast need to add servlet-api.jar to your Classpath. :)

Help Needed in JMS Provider

Hi,
In a document for JMS Connector it is given as we need to register the JMSConnectionFactory using Non-JNDI Provider, if our JMS Provider does not provide a naming system.
Does WebSphere MQ(non JMS) provides a naming system? If not should i register it using Non-JNDI procedure? When i register, its asking me to fill the Object Factory class and JMS Factory class? I am not able to find out the class implementing the javax.jms.QueueConnectionFactory and javax.naming.spi.objectFactory interface.
Please help me out.

Help needed reinitializing jms

Hi,
I have an application using a JMSTopic and a few JMS temporary queues (weblogic). If the weblogic server goes offline I get a JMSException and I then try to close my connections (topic and queue) and then reinitialize all the JMS objects. After doing that I am able to receive mesages from the Topic but when I try to send to a temporary queue (created after weblogic was restarted) I get:
weblogic.jms.common.JMSException: using closed dispatcher
at weblogic.jms.client.JMSProducer.sendInternal(JMSProducer.java:366)
at weblogic.jms.client.JMSProducer.send(JMSProducer.java:186)
I am sure I close the old connection and I start a new one and create new Session end Sender so I cannot understand what the problem could be, any help?
Thanks,
A.

At the moment I'm setting my own server up on virgin media though I will be helping a family member with their connection at a later stage.
I currently have this safecom Cable wireless router (http://safecom.cn/code/support/DMF.aspx?pid=309#) and its manual is there. I found a menu called Dynamic DNS which has dyndns.org(dynamic) as a choice. I entered in the hostname bingo.dyndns.com which is what i registered on dyndns.
What else do I need to do? I'm not to sure how to forward incoming requests. I do understand that you a routeting the queries to a specific machine and port but I'm not sure how to do it. I'm also experiencing this problem APEX username and password

Cname settings help needed for a Network Solutions Personal Domain

Hi-
I've purchased a personal domain name from Network Solutions. I've followed the instructions that Apple has given me, and have specified "web.mac.com" as the alias name, as well as specifying "www" in the drop down box in the next field to the right of the alias field. I've also set up my personal domain name on the Apple side. However, after 48 hours, I'm still seeing the "site under construction page" from Network Solutions when I go to view my personal domain. I confirmed on the Apple side that iWeb was now using my personal domain name, and I was also able to confirm that my domain name was/is pointing to web.mac.com. What am I doing wrong? Does anybody out there with a Network Solutions domain name have any experience with this?

Did you ever get an answer on this?

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:

JMS Topic Load Balancing on Cluster

Folks
How do we load balance JMS Topic on a cluster.
We have a 2 App Server configuration to a single cluster.
If we have Topic A on both OC4J instances 1,2 - and we send a message to 1 - only clients connected to 1 get the message.
What do we need to do to setup JMS clustering so that the messages sent to Topic A can be handled by both OC4J instances.

JNDI Lookup for JMS Topic issue.......!

Hi,
          Our application is deployed on two nodes (MS1 and MS2 in a cluster) and I created JMSServer on MS1, JMS ConnectionFactory and Distributed Topic are targeted on both MS1 and MS2 i.e on entire cluster.
          We have the JMS Code in postStart() method of starup class which extends ApplicationLifecycleListener which would create the JMS Subcriber and set the message listener on to it.
          code snippet:
               System.out.println("createSubscriber called");
               subSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
               // Lookup for the Topic
               Topic cadTopic = (Topic) ctx.lookup("JMSTopicLog4j");
               System.out.println("Topic is: " + cadTopic.getTopicName());
               // Create JMS Subscriber.
               cadSubscriber = subSession.createSubscriber(cadTopic);
               // Set the listener to Subscriber.
               cadSubscriber.setMessageListener(new CADMessageListener());
               topicConnection.start();
          When I start the cluster (managed Servers MS1 and MS2) for the first time and deploy the application on them (entire cluster) it works well i.e. message listener is active and able to receive messages published by publisher but when I try to stop and start MS2 it gives the following exception during server startup
          javax.naming.NameNotFoundException: Unable to resolve 'JMSTopicLog4j'. Resolved ''
          javax.naming.NameNotFoundException: Unable to resolve 'JMSTopicLog4j'. Resolved ''; remaining name 'JMSTopicLog4j'

          at weblogic.jndi.internal.WLContextImpl.lookup(WLContextImpl.java:362)
          Note: I thought my application context is getting started before JNDI tree is loaded but I could see that it is able to lookup the ConnectionFactory and throws the given exception when it comes to lookup code of JMS Topic.
          is there any configuration issue or am I missing something? Please help me in this regard.
          Thanks in advance.
          Kris.

Very interesting, I mean in the sense that we have the same setup, but instead of topic we are using the queues.
          And our problem is exactly the same,deployment works but after restart same javax.naming.NameNotFoundException happens on server 2.

Concurrent nodes reading from JMS topic (cluster environment)

Hi.
Need some help on this:
Concurrent nodes reading from JMS topic (cluster environment)
Thanks
Denis

After some thinking, I noted the following:
1 - It's correct that only one node subscribes to a topic at a time. Otherwise, the same message would be processed by the nodes many times.
2 - In order to solve the load balancing problem, I think that the Topic should be changed by a Queue. This way, each BPEL process from the node would poll for a message, and as soon as the message arrives, only one BPEL node gets the message and take if off the Queue.
The legacy JMS provider I mentioned in the post above is actually the Retek Integration Bus (RIB). I'm integrating Retek apps with E-Business Suite.
I'll try to configure the RIB to provide both a Topic (for the existing application consumers) and a Queue (an exclusive channel for BPEL)
Do you guys have already tried to do an integration like this??
Thanks
Denis

1 "simple" JMS topic and 2 cluster elements with OSB

Hi,
I have 1 simple jms topic (not distributed, not on migratable target) and cluster with 2 members - OSB as main application. My OSB proxy service reads from this topic and saves data to file.
The problem is that reading from topic appears twice - once by each cluster member. How to configure topic or proxy service for only one reading?

FYI - At this year's Oracle OpenWorld, which is being held in conjunction with this year's JavaOne, Oracle will be announcing a set of enhancements that are designed to cover this exact use case.
Tom Barnes
Session ID: S317469
Title: New Service-Oriented Architecture Patterns with Enterprise Grid Messaging
Abstract: Messaging systems are essential in enabling the flexibility and loosely coupled nature of a service-oriented architecture (SOA). Oracle WebLogic Java Message Service (JMS) includes new pub-sub capabilities that make architectures more adaptable, allowing message producers to be ignorant of who is the consumer of a message or how many consumers there are. It also enables easy scale out and dynamic adaptability through clustering and message-driven bean (MDB) enhancements, all while still guaranteeing strict message ordering. This session will outline new JMS capabilities and show how they enable new designs with Oracle WebLogic Server and Oracle Service Bus.

JMS Configuration Help Needed for Publish Subscribe Messaging

Hi,
I am new to JMS and need help to configure JMS from the sun admin console. As of now i have configured the topic and the connection factory from the JMS Resources under the Resources tab(here too i just specified the topic name and guest and password and jndi and similarly the connection factory name but have not specified any port or anything else), but i guess something is missing as i can publish but cannot subscribe nor can i view the messages on the topic..I think some sort of configuration is also need on the Java Message Service header under the Configuration tab.I have searched for this on the net but have not been able to find any sort of detailed help.If someone could give a detailed picture as too how to go about this configuration with an example it would be of great help.
