Message Driven Beans replying to messages
Hi
I'm trying to send a reply message from an MDB. What I have in mind is this:
1) in the onMessage() method of the bean, analyze the message and get the replyTo property of the message.
2) Set up the reply message and send the message back to the original sender.
I've done this using regular client-server apps, but not with MDB's. What I want to know is must I do the JNDI lookups to get the Connection factories etc in the MDB itself? Or is there some way I can get a session that already exists in the Bean Container (I'm using JBoss 3.0.2), to create the reply?
Thanks
Daniel
There is no J2EE way to get hold of the session that was used, you have to do a lookup of a Connection Factory.
Thanks

Asynchronous request/reply with message driven beans?
HI,
Can I implement requet/reply with message driven beans in an asynchronous way? If so can somebody give me some hints?
I read that this can be done by creating a temporary queue on the producer and then calling setJMSReplyTo methond on the request message and passing in the temporary queue. By how do you specify a response message in the MessageDrivenBean, MessageListener class with only onMessage()?
ThanksThe MDB can only really be used for the server side of a request-response.
I'd recommend you look at Lingo which implements request-response remoting using JMS...

Message Driven bean not able to listen to IBM MQ
Hello,
I am trying to implement a Mesage Driven Bean on Weblogic 7.0.This MDB
would listen on a particular queue of IBM MQ.
I have written a Weblogic startUp class which registers the factory
into Weblogic JNDI.Am I supposed to register the queue as well? I am
confused about the queue part. In the deployement descriptor of the
MDB (weblogic-ejb-jar.xml), we have the the <destination-jndi-name>
tag which should be the Queue name (in my case the IBM MQ queue ). Am
I supposed to register that in the Weblogic JNDI as well? I mean do I
add the Queue part in my Weblogic start-up class as well? Else how
will The Queue be obtained?
I am sort of confused on this . I get the error :
<Apr 16, 2003 3:17:14 PM EDT> <Warning> <EJB> <010061> <The
Message-Driven EJB: SimpleMDB is unable
to connect to the JMS destination: ivtQ. The EJB container will
automatically attempt to re-establis
h the connection with the JMS server. This warning may occur during
WebLogic Cluster start-up if the
JMS destination is located on another server. When the JMS server
connection is re-established, the
Message-Driven EJB will again receive JMS messages.
The Error was:
The JMS destination with the JNDI name: ivtQ could not be found.
Please ensure that the JNDI name in
the weblogic-ejb-jar.xml is correct, and the JMS destination has been
deployed.>
Please guide .I am trying to find out this information(which isn`t
very difficult i think ) since quite a few days now but I have got no
reply whatsoever.Please let me know if I am posting in the wrong group
or should I place my query in some other group where I can get a
better response.
Thanks and regards,

I'm not familiar with this stuff, but Greg is out, so
hey, I'll give it a shot. Some random thoughts:
It seems odd that the MDB can find the factory in JNDI but
not the queue.
Make sure that the startup class is actually running the code
you think it is. Put println's before and after the queue binding
code. And as the white-paper suggests, use the "failure is
fatal" option for the startup class so that you know
if the class worked or not...
Put some trace code in the ignored "NumberFormatException" catch below.
Carefully check you log to see if there are other warnings or errors.
Note that you may wish to use MQ JNDI instead of createQueue
in the startup class to look up the queue. The "createQueue()"
will not necessarily return an object that is JNDI "capable", (vendor
specific)... If this is the case, then you will need to
write a "wrapper" class that implements Serializable but
finds its wrapped factory via some sort of static lookup.
Tom, BEA
P.S. Note that WebLogic 8.1 provides the ability
to "wrap" and deploy foreign JMS resources administratively
via the console. No startup class needed...

Message-Driven Bean using @Resource annotation
I am trying to run a Message-Driven Bean very simple example in https://glassfish.dev.java.net/javaee5/ejb/examples/MDB.html
I configured MDBQueueConnectionFactory and MDBQueue properly on glassfish admin console.
I cannot run the example using @Resource annotation. I don't understand why.
@Resource(mappedName="MDBQueueConnectionFactory")
private static QueueConnectionFactory queueCF;
@Resource(mappedName="MDBQueue")
private static Queue mdbQueue;But I can run this example modifying the source code using InitialContext instance and looking up for JMS Resources.
InitialContext ctx = new InitialContext();
QueueConnectionFactory queueCF=(QueueConnectionFactory)ctx.lookup("MDBQueueConnectionFactory");
QueueConnection queueCon = queueCF.createQueueConnection();
Queue mdbQueue=(Queue)ctx.lookup("MDB");
queueSender.send(mdbQueue, msg);
...I want to figure out why @Resource annotation do not work well. Any help?
Thanks in advanced any help.Thanks for your reply.
The error that I get is a simple NullPointerException. Nothing else.
Like you said, I develop a servlet and I can use @Resource annotation without static reference, and it works.
public class TestMDB extends HttpServlet {
private static final long serialVersionUID = 1L;
@Resource(mappedName="MDBQueueConnectionFactory")
private QueueConnectionFactory queueCF;
@Resource(mappedName="MDB")
private Queue mdbQueue;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println("TEST MDB "+queueCF);
QueueConnection queueCon;
try {
queueCon = queueCF.createQueueConnection();
QueueSession queueSession = queueCon.createQueueSession
(false, Session.AUTO_ACKNOWLEDGE);
QueueSender queueSender = queueSession.createSender(null);
TextMessage msg = queueSession.createTextMessage("hello");
queueSender.send(mdbQueue, msg);
out.println("Sent message to MDB");
queueCon.close();
} catch (JMSException e) {
e.printStackTrace();
}But my question were about using @Resource annotation on a standalone client. I always get NullPointerException.
public class MDBClient {
@Resource(mappedName="MDBQueueConnectionFactory")
private static QueueConnectionFactory queueCF;
@Resource(mappedName="MDB")
private static Queue mdbQueue;
public static void main(String args[]) {
try {
QueueConnection queueCon = queueCF.createQueueConnection();
QueueSession queueSession = queueCon.createQueueSession
(false, Session.AUTO_ACKNOWLEDGE);
QueueSender queueSender = queueSession.createSender(null);
TextMessage msg = queueSession.createTextMessage("hello");
queueSender.send(mdbQueue, msg);
System.out.println("Sent message to MDB");
queueCon.close();
} catch(Exception e) {
e.printStackTrace();

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, joIt 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.

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.

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,

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.

tmsg = (TextMessage) msg;
System.out.println
("MESSAGE BEAN1: Message received: "

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:

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:

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.

JBoss message driven bean calling a session bean
Hi guys, can you please help me? I want my mdb to call my session bean....can you provide me some examples of ejb-jar.xml and jboss.xml with regards to this configuration....thanks...im creating my deployment descriptors manually
Here is a little example, I hope it will help you.

Message Driven Bean: problem with @RunAs annotation
I am having a problem using the @RunAs annotation in a message driven bean.
I would like the code in my onMessage() method to be executed with a specific role/user, so I want to use the @RunAs annotation to achieve this.
I am running weblogic 10.0.
I have created the following in weblogic console:
- Group "TestGroup"
- User "TestUser", member of "TestGroup"
- Global Role "TestRole", role condition: "Group : TestGroup"
The MDB:
package be.cegeka.test.mdb;
import javax.annotation.Resource;
import javax.annotation.security.RunAs;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.ejb.MessageDrivenContext;
import javax.jms.Message;
import javax.jms.MessageListener;
@MessageDriven(
mappedName = "testQueue",
name = "TestMDB",
activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
@RunAs("TestRole")
public class TestMDB implements MessageListener {
@Resource
private MessageDrivenContext mdContext;
* {@inheritDoc}}
public void onMessage(Message msg) {
System.out.println("Handling message for user "
+ mdContext.getCallerPrincipal().getName());
}[u]The ejb-jar.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"
version="3.0">
<assembly-descriptor>
<security-role>
<description>
Test Role.
</description>
<role-name>TestRole</role-name>
</security-role>
</assembly-descriptor>
</ejb-jar>
The weblogic-ejb-jar.xml file:
<weblogic-ejb-jar xmlns="http://www.bea.com/ns/weblogic/10.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/10.0 http://www.bea.com/ns/weblogic/10.0/weblogic-ejb-jar.xsd">
<security-role-assignment>
<role-name>TestRole</role-name>
<principal-name>TestUser</principal-name>
</security-role-assignment>
</weblogic-ejb-jar>I would have thought that the onMessage of the MDB would print "Handling message for user TestUser", but instead it prints "Handling message for user <anonymous>".
It seems as though the @RunAs annotation has no effect. Although I specified the role TestRole (mapped to the user TestUser), the code still seems to be executed by user anonymous.
Am I missing something?
Any help would be much appreciated! I've been looking at this poblem for quite a while now.Both beans (the MDB on WLS 10 and the session bean on WLS 8.1) use container managed transactions.
For the MDB I do not explicitly set the transaction attributes, so it should default to container managed transactions.
For the stateless session bean I have specified the following in the ejb-jar.xml file:
<ejb-jar>
<display-name>Weblogic8Service</display-name>
<enterprise-beans>
<session>
<ejb-name>Weblogic8Service</ejb-name>
<home>be.cegeka.rszv.test.session.Weblogic8ServiceRemoteHome</home>
<remote>be.cegeka.rszv.test.session.Weblogic8ServiceRemote</remote>
<ejb-class>be.cegeka.rszv.test.session.Weblogic8ServiceBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
<assembly-descriptor>
<container-transaction>
<method>
<ejb-name>Weblogic8Service</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>So as far as I understand it the transaction starts at the MDB (upon receival of a message). The transaction for the remote call to the stateless session bean (in the onMessage() of the MDB) is included in the transaction of the MDB and gets committed when the onMessage() method finishes and the transaction of the MDB itself gets committed.
Correct me if I'm wrong here. -
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.

Message Acknowledgement in a Message Driven Bean
Does the message acknowledgement in a Message driven bean take place after the transaction commits? Will the message be available to be consumed by another instance of the MDB in case the transaction was rolled back? I am using WLS 7.0 as my app server and SonicMQ as JMS provider.
Thx.
Ajanta.
Yes, ack's are delayed until the transaction commits.
Yes, the message will be available if the transaction is rolled back.

Create EJB 3.0 Message Driven Bean on a Oracle JMS (AQ)
Hi, I need to develop a EJB 3.0 Message Driven Bean. The MDB has to work on a Oracle AQ using Oracle JMS. Is there any how-to document giving an example about this issue. Can you give an example how to create the JMS destination in OC4J (how to configure the Oracle JMS AQ in OC4j), issue the JMS destination via annotions (resource injection) in the MDB. Please give me a working example of the MDB and a test client to produce a message. Regards, Arjan Jorritsma
Check your ejb-jar.xml and see if it has the version of "2.1" there...
If the application was depending upon EJB 3.0 annotations but it had a ejb-jar.xml that had version set to "2.1" and there was no oracle specific descriptor (orion-ejb-jar.xml) to designate it use the resource adapter; It would expect JMS destination and connection factory that is required for a JMS-MDB set in the ejb-jar.xml. So try to change the ejb-jar.xml to update the version to "3.0", OC4J would have parsed the annotation and combined the metadata with ejb-jar.xml and it would work.
