Only one Message Driven Bean
hi
i have some heavy calculating beans and i want that only one EJB is calculating at one time. can i do this by using Message Driven Beans? is it possible that the server creates only one Message Driven Bean at one time and gets the next one out of the queue when the old one finished calculating?
thanks, jo
It is possible to set up that there should be only one mdb in the pool, but it's not quite what mdbs are intended for. Remember that this is an asynchronous message service, and you will not receive a reply after you put a message on the queue.

WLS Cluster with Message Driven Beans and MQSeries on more than one Host
With the Examples of http://developer.bea.com/jmsproviders.jsp and http://developer.bea.com/jmsmdb.jsp
a MDB can be
configured to work with MQSeries with one WLS Server. This works only, if a Queuemanager
is started at the same Host that runs the WLS Server too.
And the QueueConnectionFactory (QCF) is configured to TRANSPORT(BIND).
In my configuration should be two WLS Servers and one JMS Queue (MQS) with the
Queuemanager.
A Message Driven Bean is deployed on both WLS Servers wich should get the Messages
of this Queue.
If one of the two WLS Servers fails the other WLS Server with the corresponding
MDB should get the Messages of the
MQSeries Queue.
If the QCF is configured to TRANSPORT(Client) the Message Driven Bean can't start
and the following Exception is thrown:

I'm wondering, because their is a MQQueueManager on btsun1a; all Servers throws
the same Exception when the MDB is deployed.
The configuration of JMSadmin on both Hosts is the following:

I think only TRANSPORT(CLIENT) can be used when i don't wan't to install a Queue

Does anybody know a problem of WLS 6.0 SP2 to cope with TRANSPORT(CLIENT)?

Can you set isolation levels of message-driven bean transactions?
The problem: I have 3 different message-driven beans which each get a different type of message, except for a field that is common to all. That field is used as the primary key of an entity object. The message-driven beans configured to use a container managed transaction. Each message-driven bean, in processing the message, first does a lookup by primary key to see if the object associated with the key exists, and if it does not, it requests the entity's home object to create it. After that, they do further processing. The problem is that sometimes all the beans simultaneously get a message, resulting in each bean checking for the entity object at about the same time, and if they fail to find it (because none of them has created it yet), each creates an object, all with the same primary key. This is not caught until the beans start to complete their onMessage method, which I believe results in the container committing the transaction. One of the transactions will be committed successfully, while the other two will fail, get rolled back, and then be retried with the same message. The second time through, the other beans will find the entity object (since it has been created and committed) and they will complete correctly. In the end, they right thing occurs, except that there is a troubling exception or 2 in the log telling about the constraint violation (with the primary key) and the rollback. If it was just me, that would be fine, but our customer does not like to see exceptions in the log; that indicates to him that something is wrong.
So, I am looking for someway to make sure that the actions of the message-driven beans are serialized. One suggestion from a colleague was to set the isolation level of the transactions being used by the container in processing the message-driven beans' onMessage method. However, the documentation does not mention any way to do this for a message-driven bean. Suggestions?
Is the use of a UserTransaction a better way to do this? If I acquire a UserTransaction within the onMessage method of a message-driven bean, can I set its isolation level? How would this work? When I get a UserTransaction, does each client get a different transaction, or do they all get the same one?(1) The WebLogic JMS "unit-of-order" feature is a heavily adopted feature that was specifically designed to handle similar use cases - see the JMS developer guide for extensive documentation. In your use case, if "key" is used to define UOO, then there's no limit on the number of keys that can be processed concurrently, but messages for any particular key will be processed single-threaded in the order in which they were first submitted.
Note that if you're using distributed destinations, the UOO feature is still fully supported - but the developer and/or administrator needs to decide whether to configure the destination to use "hash" or "path service" based routing (the JMS UOO edoc outlines the trade-offs).
(2) Another alternative is to use a single MDB with max-beans-free-pool that processes all three types (as the other poster suggested). I think this assumes all MDBs run on the same JVM.
(3) Another alternative is to use multiple queues, with a single MDB on each Q. Where some sort of hash algorithm is used to determine which Q is for the key. This approach is a "hand-coded" variant of the approach in (1) with "hash" based routing enabled...
(4) If all MDBs actually do run in the same JVM, a third alternative is to use code the application to use a common lock to protect each key, eg, something like:
// assume MyLock is simply a class with a "reference counter"
// assume some global "staticHM" hash map that is all MDBs can access
onMessage() {
MyLock lock = null;
key= msg.getKey();
synchronized(staticHM) {
lock = staticHM.get();
if (lock = null) {
lock = new lock();
staticHM.put(key, new lock());
lock.incRefCount();
try {
synchronized(lock) {
// only one onMessage will be able to lock a particular key at a time
do your work;
} finally {
synchronized(staticHT) {
if (lock.defRefCount() == 0) staticHM.remove(lock);
if (lock = null) staticHM.put(key);
If multiple threads get a message with the same key, then only one thread at a time will work on the key.
Hope this helps,
Tom -
How to configure my MDB serve only one message at a time?
Hi All,
I have requirement where I need to develope a MDB iin weblogic. This MDB has to serve only one message at a time. If the send second message is sent while the first one is running the second message has to sit in queue and start processing once the first message is finished.
Is there any way to configure via annotations or in weblogic server settings ?
Any help would be really appreciated...
Thank you,
K.Here is my client code to send the message
Connection connection = null;
javax.jms.Session session = null;
MessageProducer producer = null;
try
connection = lpConnectionFactory.createConnection();
session = connection.createSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);
// Create a MessageProducer from the Session to the Validation Queue
producer = session.createProducer(myQueue);
((WLMessageProducer)producer).setUnitOfOrder();
// Create a message
ObjectMessage message = session.createObjectMessage();
message.setObject(params);
message.setStringProperty(MyServiceConstants.OPERATION, operation);
// Send the message to the queue
producer.send(message);
finally
if (producer != null)
producer.close();
if (session != null)
session.close();
if (connection != null)
connection.close();

Error during deployment of Message Driven Bean
Environment: WLS 6.1SP3 on Win2K SP2, non-clustered.
I am getting some error (or perhaps warning) during deployment of Message
Driven Bean. Any one seen this before?
This error only comes on a machine with Dual Network card.
Thanks.

Hi Tom
Yes we do have an URL provided in the descriptor. It's
t3://jms.server.net:7001.
and the jms.server.net is resolved via a hosts file in Win2K
eg,
192.168.100.200 jms.server.net
You are right in saying that the loopback in a dual-net card is a problem.
But our solution
above solves the issue as long as your host file does not use 127.0.0.1 as
the IP.
We need the URL b/c depending on our client's deployment , the JMS Server
may be remote or may be local.

Hello,
i'm an Italian student trying to develop java applications in NetBeans IDE 6.1 with GlassFish V2, using Java EE 5; since I only recently approached java web programming, I have encountered some problems in using enterprise beans, especially message-driven ones: to get in touch with the stuff, I have created an enterprise application project in NetBeans with a plain message-driven bean and a servlet who sends a message to this bean, following an online netbeans tutorial.
I'm using annotations to refer the resource in the servlet (the jms name I assigned the bean is "TestBean"):
@Resource(mappedName="jms/TestBeanFactory")
private ConnectionFactory connectionFactory;
@Resource(mappedName="jms/TestBean")
private Queue queue;I send the message by creating a connection, producing the message with a MessageProducer object, and sending it:
Connection connection = connectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
MessageProducer messageProducer = session.createProducer(queue);
TextMessage message = session.createTextMessage("This is a message.");
messageProducer.send(message);
messageProducer.close();
connection.close();In the message-driven bean, I have my onMessage() method catching the message and writing to the system.out his text content:
public void onMessage(Message message)
TextMessage msg = null;
try
if (message instanceof TextMessage)
msg = (TextMessage) message;
String x = msg.getText();
System.out.println(x);
catch (Exception e)
e.printStackTrace();
m_ctx.setRollbackOnly();
catch (Throwable te)
te.printStackTrace();
}The message is sent and received, and the content printed. Ok, here are my questions:
1) in the output window of netbeans I see the output but also an exception: "DirectConsumer:Caught Exception delivering messagecom.sun.messaging.jmq.io.Packet cannot be cast to com.sun.messaging.jms.ra.DirectPacket". What does that mean?
2) I can't figure out how to make the bean answer this message to the servlet...and of course the servlet receive this response: in plain words, I would like to send back another message from the bean to the servlet, and process it. Can someone explain me how to do that?
Thanks?1) in the output window of netbeans I see the output but also an exception: "DirectConsumer:Caught Exception delivering messagecom.sun.messaging.jmq.io.Packet cannot be cast to com.sun.messaging.jms.ra.DirectPacket". What does that mean?casting issue, but i don't know why.
2) I can't figure out how to make the bean answer this message to the servlet...and of course the servlet receive this response: in plain words, I would like to send back another message from the bean to the servlet, and process it. Can someone explain me how to do that?a message driven bean cannot sent a response back. MDB is asynchronous. if you need to send a response back, you
shouldn't be using an MDB. In that case, it sounds like you want a synchronous response. let a SLSB do it.

Message driven bean: resource not created
Hi,
I'm having trouble deploying a simple test app that I've created (in App Server Platform Edition 8.0). It contains a servlet, that posts messages to a queue, and which appears to work fine. There is also a message-driven bean that receives these messages, but it will not deploy as is. I would be grateful for any assistance in working out why. Apologies if I'm missing something obvious, but the technology is quite new to me.
I get the following error in the server log -

Thanks,
JoeHi, Joe,
The message says that
JMS resource not created : joeMDB
The command to add the missing Queue:
asadmin create-jms-resource user admin restype javax.jms.Queue JoeDestQueue
Please note:
in your sun-ejb-jar.xml, the real JNDI name for the Queue is JoeDestQueue.
Double check the namings for the Queue in both ejb-jar.xml and sun-ejb-jar.xml.
You only need two names for one Queue: one is for JNDI, one is for reference.

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?)

Jndi-name in Message Driven Bean
Hi
I have successfully created the ejb jar file for deployment using sun one studio . I created the message driven bean and I right clicked on the ejb and used the customize option to set the bean properties . But my problem is that the jndi-name in the <ejb> tags takes the value jms/(ejbname) instead of jms/(queuename) . I am attaching the xml file with this . Can any one tell how to set the jndi-name to queue value using studio

Thanks for your response. I think from EJB container we can call Local EJBs with the full JNDI name. The session facade bean which is being called is a remote bean. From the session facade bean I am calling a local stateless session bean for database access. I am getting the reference of the local EJB from my session facade bean with full JNDI name "java:comp/env/ejb/EJBJNDIName". It is working fine with out any problem. My servicelocator is able to provide me the reference of the local EJB from the session facade remote bean with Full JNDI name. I am only having this problem calling from the MDB. I am really not sure whether what is causing it?
Thanks

Hi,
what does the bean technology add to the JSM by using the message driven beans instead of just using the regular asynchronus JMS?that's my question when and why should we chose:
1. simple asynchronous JMS
2. message-driven beansYou presumably mean:
1. "simple" JMS client
2. MDB JMS client
That'll depend first on your existing architecture.You'll go for the second option if you're already using EJB , as to leverage your existing IT investment.
Second, the EJB container gives you a number of services, so you don't have to worry about those yourself: life cycle management, scalability, transaction support, concurrency etc..
With a plain JMS client, you'll have to handle concurrency yourself, for example, by spawning different JMS instances.
If you're using an EJB container, that container will instantiate multiple MDB instances to handle multiple messages simultaneously.
OTOH, The EJB contract implies some limitations of use. For example, an MDB can be associated with only one queue or topic. So if you need a JMS client to be able to handle multiple queues ot topics, you'll need to create multiple MDB clients, or go for a simple non-MDB JMS consumer. -
How to transaction in the message driven bean?
hello
i write a message driven bean,that monitor the weblogic message queue,when a "Order"
object is witten to the queue,the mdb get it and write it to a entity bean "Orderinfo".all
of above logic is within the "onMessage" method of the mdb.
i want to encapsulate the flow in a transaction,see my code snippet of the onMessage
method:
ObjectMessage objMsg = (ObjectMessage) msg;
OrderVO orderVO = (OrderVO) objMsg.getObject();
System.out.println(orderVO.booklist);
OrderinfoHome orderinfoHome = (OrderinfoHome) ctx.lookup(
"java:/comp/env/orderinfo");
Orderinfo orderinfo = orderinfoHome.create(orderVO.orderID);
orderinfo.setAddress(orderVO.address);
orderinfo.setCustname(orderVO.custName);
orderinfo.setEmail(orderVO.email);
orderinfo.setBooklist(orderVO.booklist);
orderinfo.setPrice(new BigDecimal(orderVO.price));
and deploy descriptor snippet(ejb-jar.xml):
<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>orderMDB</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
i think during this transaction,there are two action:geting the object from the
queue and saving it to entity bean.in order to test the transaction,i modify the
jndi name of entity bean in the code to a WRONG one.redeploy my program,and send
a message to the queue,the mdb is activated,then the exception is thrown because
of the wrong jndi name.after that,i check the message queue,find that it is empty.why?i
think if the second action of the transaction is fail,the transaction should roll
back,the message should be send BACK to the queue.
i also ty to use the "javax.transaction.UserTransaction" in the onMessage method,but
the follwing exception is thrown:
javax.transaction.NotSupportedException: Another transaction is associated with
this thread.................................
who can help me,if any wrong with me,and how to use the transaction with the message
driven bean?
thank you.
The transaction should rollback if the MDB throws an
exception. Try changing your MDB code to
call "setRollbackOnly()" on the EJB
context (instead of throwing an exception) to see
if that works. If calling "setRollbackOnly()" fixes
the problem - then please contact customer support
and report a bug.

Message Driven Bean and transaction handling
We are using container managed transactions with MDB's running on OC4J version 10.1.2. We have two database serveres, both running Oracle 10g.
The MDB consume messages from the AQ-database through JMS (connected to a JDBC datasource registered as "jdbc/OracleAQDS").
The MDB onMessage() code update the second database, using a JDBC datasource registered as "jdbc/OracleDBDS".
We need atomic behaviour - if the MDB enforce a roll-back we want the updates aginst the second database to be rolled-back as well.
(1) Should we use XA-datasources since AQ and DB runs on two different servers or do the OC4J container "magically" provide two-phase-commit for us?
(2) If the MDB does a roll-back we would like to add an error record to a database table. Can we configure a third datasource and prevent if from beeing part of the container managed MDB roll-back?
(3) When the MDB force a roll-back, is there some way for us to override the retry-delay in our Java code? If we catch certain errors during processing in onMessage we know that it is not necessary to retry for at least one hour (while less severe errors should be retried in just seconds).{color:#008000}Hi Friends,
Thought of updating the answers for my questions in case somebody else would find it helpful.
{color}
{color:#999999}{color:#00ccff}I'm trying to make message driven bean and use the OnListener method.
But since I'm doing this for the first time I have very limited knowledge.
The following are my doubts :
1. Should I have a main function while using the MDB?{color}
{color:#008000} There is no need for any main function.{color}
{color:#00ccff}2. Is it mandatory to have JNDI setup done?
{color} {color}{color:#008000} There is no need for any JNDI setup done. But you need to configure the details on the
Websphere by creating valid entries inside Resources namely -
Queue Connection Factory, Queues and Listener Ports under the server.

WebLogic 10 and EJB 3.0 for Message Driven Bean
Hi,
I am trying to deploy Message Driven Bean using EJB3.0 on weblogic 10. I am using annotations and don't want to use deployment descriptors.

TextMessage tmsg=null;
try {
if (msg instanceof TextMessage) {
tmsg = (TextMessage) msg;
System.out.println
("MESSAGE BEAN1: Message received: "
+ tmsg.getText());
} else {
System.out.println
("Message of wrong type1: "
+ msg.getClass().getName());
catch (JMSException e) {
e.printStackTrace();
catch (Throwable te) {
te.printStackTrace();
My client:

message.setText("This is message by Gurumurthy" );
System.out.println("Sending message: " +message.getText());
sender.send(message);
sess.close();
catch (Exception e)
e.printStackTrace();
I am compiling and creating jar file for this class. Then I am creating a .ear file for this.
The meta-inf/application.xml contains the following:
<?xml version="1.0" encoding="UTF-8"?>

<module>
<ejb>MDBWorking1.jar</ejb>
</module>
</application>
I don't want to use deployment descriptor (ejb-jar.xml or weblogic-ejb-jar-xml), because I want to utilize the annotation feature of EJB3.0
So, after creating the .ear file for this, and try to deploy on weblogic 10, I get the following error:
An error occurred during activation of changes, please see the log for details.

How to solve this?
Note:
I don't want to use Deployment Descriptor and all I want to use is EJB3.0's annotation feature.
Thanks,
GuruDear gurubbc,
I don't know if it still matters to you but you can use the javax.ejb.MessageDriven annotation to point your bean on your queue. I had the same issue like you but i could not solve it properly by switchihg to weblogic.ejb.MessageDriven.
Use the following annotation and it should work out:
@MessageDriven
(mappedName = "queue/mdb",
name = "CalculatorBean",
activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
Here you can see that the mappedName is the JNDI name of the queue you are trying to connect to. The name is the name for your Bean, and the only property passed is the destination type.
Hope this helps.
Cheers,

You have not created the jms destination queue object
jms/Warehouse
Your server logs says it cannot find the destination queue object.It has got nothing to do with jndi name of your bean
Create jms destination queue object using
asadmin>create-jms-resource instance <instance_name> resourcetype javax.jms.Queue --property imqDestinationName=<NAme> jms/Warehouse
Then use list-jms-resources <instance_name> to
find if jms/Warehouse destionation queue object has been created.
