Transaction Management - App Module in Stateless Session Bean

Hi All,
We are using Application Module in local mode in a Stateless Session Bean. The application module gets the database connection from the datasource of the application server(Oracle 9iAS).
The problem that we are facing is as follows
- When a database update/insert is made using the Application Module and the ViewObject (and the underlying Entity Object), the changes are not being commited.
Please note that we are not using the ApplicationModule.getTransaction.commit() as it does not give us commit/rollback control from another Session Bean/UseCase. We instead are relying on the Container to manager the transaction and commit the database changes. But the container does not seem to refresh the changes to the database.
Q1 - Is there a contract between the container and the application module that needs to be created so that the container managed-transaction and the application module work together ?
Any help in this matter would be greatly appreciated.

Q1 - Is there a contract between the container and the application module that needs to be created so that the container managed-transaction and the application module work together ?For stateless beans you have to call postChanges in the business method for the changes to be applied to the db. For stateful beans bc4j we do that automatically just before the transaction ends.
Take a look at the following howto
http://otn.oracle.com/products/jdev/howtos/bc4j/ejbstateless_with_bc4j.html
In 9.0.3 you'll be able to create a stateless service bean declaritively.
dhiraj Hi dhiraj,
- I looked at the example but was not able to find the ContainerManagedTxnHandlerImpl class in the BC4J jars. Can you point me to the latest version of BC4J on technet ?. I already have JDeveloper 9.0.2
- Regarding your response, what do you mean by creating stateless service bean declaritively ?
Thanks,
Ankur

Deploying App Module as EJB Session Bean to JBoss

I am attempting to follow the How-To at
http://otn.oracle.com/products/jdev/howtos/appservers/deploy_bc4j_to_jboss.html for deploying BC4J to JBoss. In particular, I was looking at the section 'BC4J as an EJB Session Bean', because that is the route we would like to take.
The document instructs you to create a business components deployment profile.. ok, done.
It then instructs you to copy the app module configuration that was just created and rename it. However, the editor will not let you rename the configuration.
Then when 'Creating a JSP to Access Your Application Module as a EJB', the wizard to create the JSP will not allow you to select the app module configuration that was just created. It only shows the Local configuration.
What am I doing wrong? I am using JDeveloper 9.0.3.1.
My ultimate goal is to take an existing BC4J/JSP application and deploy the app module as an EJB, so the JSP and EJB can reside on separate machines.
Any pointers that anyone can give me about deploying an app module as a Session Facade (BMT) to JBoss, with a JSP front end, is greatly appreciated. I have read the how-tos available from OTN. I have relatively little experience with EJB, so please forgive me if there's something obvious I'm missing.
Thanks!!!

Can this be solved by application module pooling? How
can we use the PoolMgr to work with the session
beans?You can use a stateless checkout/checkin appmodule.
Take a look at the following help topics which explain this in good detail.
"About Application Module Pooling"
"About JSP Pages and Application Module Pooling"
The pool can help reuse the appmodule instance across requests thus reducing the number of concurrent db sessions.

Transaction can be applied to stateless session bean

is transaction can be applied to stateless session beanif yes/no why?

Just because a stateless session bean is stateless doesn't mean it doens't hold state. The stateless means it shouldn't hold any client state.
It can hold onto for example the dao objects.
The idea is that you pass all the client state to the sessionbean when calling it.
Eg.
public void doBulkOperation( User user ,string param1, String param2){
operation1( user, param1 );
operation2( user, param2 );
public void operation1( User user ,String param1){
//do some work involving user
public void operation2( User user ,String param2){
//do some work involving user
now suppose that doBulkOperation, operation1, operation2 are declared as transaction required. doBulkOperation starts the transaction if there isn't one running and joins the transaction. Then operation1 and operation2 join in the transaction.
Perfectly safe!
What you're not allowed to do is the following:
privata User user
public void doBulkOperation( User user ,string param1, String param2){
this.user = user;
operation1( param1 );
operation2( param2 );
public void operation1( String param1){
//do some work involving user
public void operation2( String param2){
//do some work involving user
This would be unsafe because concurrent calls will change the user and produce unpredictable results and possibly corrupting data.
It will work perfectly thougn if there is only one user or you're using a statefull session bean providing you don't share that bean with several clients.

Transaction not rolling back in stateless session bean

          Hi,
          I am facing a problem...
          I have one stateless session bean which does multiple updates in SYBASE database.I
          am using non-transactional datasource. Bean calls a method of data access obejct
          whcih internally calls more than one one mehtod to update different tables.If
          any of update fails then I am explicitly thorwing EJBException. Still it is not
          rolling back.
          I have one more application where similar situation is there but only difference
          is that there we have Entity bean and updates are being done through store method.
          In that case with same datasource it is rolling back perfectly.
          I have tried with transactional datasource as well but it didn't work.Then I tried
          to put setAutoCommit(false) in my connection class which gives me connection.But
          then it is not allowing me to enter into my application.
          In deployment descriptor for both the beans transaction attribute is required
          for all methods.
          Regards.
          Rahul.

Pl Clear my doubts on Stateless session Bean

Is it necessry to Have isolation level and transaction attribute to be mentioned Stateless session Bean.
and where this to be done.
Help is highly appreciated

There are default (leaving transaction state alone) - so you don't have to specify it.
I'm open to correction: isolation level is specified by the vendor specific configuration whereas transaction attributes are defined in ejb-jar.xml
isolation level is a tuning parameter, whereas the transaction attribute is a design issue.
You shouldn't specify transaction where they don't need. I have seen a number of applications where full transaction level is specified on all methods, and then they wonder why their application is slow.
A transaction is only required if atomic operations are in place. For instance, you don't need transactions on a getter, you may need them though on a setter, iff the setter does more than one thing and those things depend on each other.

Transaction management in stateless session beans.

Hi all,
I am using EJB 1.1.
I have a statless session bean that has two methods- A and B.
which does not involve any database interaction
like inserting/updating/deleting the data in the database.
The process flow is such the client always calls A first followed by the call to B.
I have the Transaction attribute set as TX_REQUIRED at the whole bean level.
Now my question is as follows:
Since it is a stateless bean, ejbCreate() is called for every method's invocation.
So does it mean that a new transaction is started for every method invocation?
Also since a transaction ends by commit/rollback.
The transation associated with the method A/B will never get completed as there is no commit/rollback involved in method implementation.
So how is this transaction ended?
Any more details about the transaction management in stateless session beans is highly appreciated.
Any input at the earliest is highly appreciated.
Thanks in advance.

Since it is a stateless bean, ejbCreate() is called for every method's invocation.For stateless session bean , Create() is not delegated to the instance.
So does it mean that a new transaction is started for every method invocation?This depends opon the Tx attribute and sequence of calls. Since you have given Tx_required then if you call any method and there is no Tx context associated with client,then a new TX will be started by container othere wise it will execute in the same TX context as the calling client. Note that client can be jsp or other ejb method.
Also since a transaction ends by commit/rollback.
The transation associated with the method A/B will never get completed >as there is no commit/rollback involved in method implementation.
So how is this transaction ended?If you are using COntainer managed TX then Transaction handling like starting , ending etc is handled by the container. You need not worry about that.
Any more details about the transaction management in stateless session >beans is highly appreciated.
Any input at the earliest is highly appreciated.Some time back I had read the article on how the Transaction management done by container on IBM Site. I dont have URL , but you can search the site.

EJB Stateless Session Bean Transactions

I have a stateless session bean.
Its deployment descripter references a JDBC DataSource.
It uses container managed transactions.
If I make JDBC calls, within a business method
of this stateless session bean, with the referred datasource, is it attached
to a container managed transaction?

If I make JDBC calls, within a business method
of this stateless session bean, with the referred
datasource, is it attached
to a container managed transaction?IIRC, yes. For CMT, the container will roll back any JDBC actions carried out by a method if it fails.

Not be able to obtain a transacted session within stateless session bean

I need some assistance on creating a transacted session. For some reason while within a stateless session bean, I am unable to create a transacted session even though I'm specifying to create the transacted queue session. Can anyone provide any assistance to me on this? It would be much appreciated.
Here is the code snippets involved with the problem:

I found the answer through lots of painful searching.
http://blogs.sun.com/fkieviet/entry/request_reply_from_an_ejb
This weblog from Frank Kieviet from a sun blog explains what's happening behind the scenes.
Then I proceeded to create a Bean-Managed Transaction out of my EJB, which is using EJB 3.0. This requires the tag:
@TransactionManagement(value= TransactionManagementType.BEAN)
Note: I got this information from http://download.oracle.com/docs/cd/B31017_01/web.1013/b28221/servtran001.htm#BAJIBAFF
Then I just added the code specified in Frank's blog and everything is working now. The main portion of the code looks like this now:
//begin the user transaction
ctx.getUserTransaction().begin();
//Create the infrastructure (ie. The connection & the session)
logger.log(Level.FINE, "Creating connection");
con = connectionFactory.createQueueConnection();
//Create the session
logger.log(Level.FINE, "Creating session");
session = con.createQueueSession(false, Session.SESSION_TRANSACTED);
transacted = session.getTransacted();
logger.log(Level.FINE, "Is session transacted? : " + transacted);
//Now create the sender that will make the request message and put it on the request queue
logger.log(Level.FINE, "Creating Sender");
sender = session.createSender(requestQueue);
//Now create the message
message = session.createTextMessage();
//Now add the actual info you want to send
message.setText(msgBody);
logger.log(Level.FINE, "Created message: " + message.getJMSMessageID());
//Now first, setup the temporary reply queue and its listener
replyQueue = session.createTemporaryQueue();
if(null != replyQueue)
logger.log(Level.FINE, "Created temporary queue: " + replyQueue.getQueueName());
else
logger.log(Level.FINE, "Temporary Queue could not be created.");
//make sure that you put the "JMSReplyTo" property to the temporary response queue we just created
message.setJMSReplyTo(replyQueue);
//Now send the message
logger.log(Level.INFO, "Sending message: " + message.getText());
sender.send(message);
//Now start the connection
logger.log(Level.FINE, "Starting the connection");
con.start();
//commit the changes
ctx.getUserTransaction().commit();
ctx.getUserTransaction().begin();
//Create the receiver
logger.log(Level.FINE, "Creating Receiver");
receiver = session.createReceiver(replyQueue);
//Now wait until we get a response
logger.log(Level.FINE, "Waiting for the response message");
Message responseMsg = receiver.receive(20000); //Toggle the "0" to specify timeout in millisectionds
//Process the message
logger.log(Level.FINE, "Processing the response message");
if(null != responseMsg)
logger.log(Level.FINE, "responseMsg is : " + responseMsg.toString());
else
logger.log(Level.FINE, "No response came back.");
messageID = processMessage(responseMsg);
logger.log(Level.FINE, "Response is : " + messageID);
logger.log(Level.FINE, "Transaction is complete");
//commit the changes

Transaction is not Rolling Back in Stateless Session Bean

          Hi,
          I am using UserTransaction in Stateless Session bean .
          Transaction is not rolling back.
          The following code is writen in stateless session bean. In UserTransaction i am
          calling Two methods of another stateless session bean.
          The problem is if doJob2() method fails, doJob1() method is rolling back. These
          two methods consist of SQL statement with different Connection Object from TXDataSource.And
          session bean(TestSession) is set to CMT, attribute as "Required".
          try{
          Context ictx=new InitialContext();
          TestHome home=(TestHome)ictx.lookup("TestSession");
               utx = sessionCtx.getUserTransaction();
               utx.begin();
          TestRemote remote=home.create();
               remote.doJob1();
               remote.doJob2();
               utx.commit();
          }catch(Exception e)
               try{
               utx.rollback();
          }catch(Exception ex)
               System.out.println("unable to rollback"+ex);
          if any SQL Exception as occured in doJob2(), its calling method utx.rollback()
          in catch block. but SQL statements executed thru. doJob1() are not rolling back.
          what might be the reason?
          thanks

A question about entity manager in stateless session bean.

JSR 220 ejbcore, page 47 : stateless session bean: All business object references of the same interface type for the same stateless session bean have the "same object identity", which is assigned by the container.
So, if we have two session beans in client code...
@EJB Cart cart1;
@EJB Cart cart2;
then cart1.equals(cart2)==true
If we declare entity manager in stateless session bean:
@PersistenceContext( unitName="ds" ,type=PersistenceContextType.TRANSACTION)
private EntityManager em;If cart1 and cart2 are the same reference, do we have any problem when using the same reference(maybe the same em? ) to get data from db?

If cart1 and cart2 are the same reference, do we have
any problem when using the same reference(maybe the
same em? ) to get data from db?No. In EJB, there is a distinction between the EJB reference and the bean instance.
Each time you make an invocation on an EJB reference for a stateless session bean,
the container can choose any instance of that bean's bean class to process the
invocation. That's true whether you invoke the same reference multiple times or
two difference references to the same bean.
Each bean instance is guaranteed to be single-threaded.

Transactional error when using JMS from stateless session bean

I get a transaction exception when committing a bean method responsible for sending to a JMS topic. This happens only occasionally when two separate threads invoke this method "at the same time".
The scenario:
Two separate threads running two different instances of a stateless session bean (slsb A). This ejb (slsb A) has an injected slsb B which is communicating with the the topic.
Both instances of slsb A are utilising the same instance of slsb B.
The CMT transactions for the two threads start in slsb A from methods with transaction attribute "RequiresNew". All nested methods are to other slsbs and have the transaction attribute "Required". The method in slsb B which sends the message is closing both the session and the connection to the topic.
I'm running Glassfish version 9.1_02 (build b04-fcs) and JMS implementation OpenMQ version 4.1.

I would suggest opening a case with [email protected] FWIW, I recall seeing
          something like this in WLS 6.0. I believe it is fixed in WLS 6.1

Bean-managed stateless session bean can't roll back using JTA

I use weblogic6.1sp2 + jdk131
a stateless session bean must do 2 things:
insert a record to A table and delete another record in A table
this bean has the same structure as the example in
j2eetutorial/examples/src/ejb/teller
I use TxDataSource in weblogic
if delete fail, the roll back is run,but in database,
the insert record is STILL in A table.
any idea?

make sure that your deployment descriptor says "transaction required".
Also, If the insert and delete are two different methods, the client must call these two methods in the same transaction scope.

TX isolation level with stateless session bean in oc4j

Hi All,
I have a stateless session bean with container managed transaction method. This method is called in a Servlet. This method retrieves data from database using 'ejb-location'connection pool and closes the connection inside. Max-connection setting for connection pool is 50
I am facing a problem running servlet multiple times.
When i have the tx_attribute as Supports, it works fine. I can run the servlet hundreds of times
But when i have the tx_attribute as Required, i am able to run servlet only 50 times and further it says 'Max connection limit exceed..unable to get the connection'.
I assume that with 'Required' attribute, it starts a transaction. Why is the transaction not getting completed at end of method? Is transaction hanging somewhere?
I assume that i am closing the connection properly as it is working fine with supports attribute.
When i monitor database, there are only 20 connections.
Why am i seeing this behaviour?
Thanks

Hi Deepak,
Thanks for your reply.
Actually, our stand alone java application already using spring-hibernate feature. Now we are planning divide our application into modules and deploy each module as ejb beans. As it is already integrated with spring-hibernate we are not using entity beans as of now. My understanding is container uses some default transcation management .so, my question is what are all the configurations needs to be done to let weblogic 10.0 server uses org.springframework.orm.hibernate3.HibernateTransactionManager. I mean, is there are any .xml file in weblogic to configure all these? please reply deepak I am struck here..

Did you manage to solve this? I'm doing something similar and seeing the same problem, although they're up to 7.3 SP7.
Any help greatly appreciated.
