Nabble - Bitronix Transaction Manager

Re: bitronix.TM to spring.jtaTM

2009-11-16T23:24:11Z

This looks like a classpath problem to me.

Please check that you don't have geronimo-jta_1.0.1B_spec.jar (or jta.jar) and btm-x.x.x.jar in your WEB-INF/lib but only in TOMCAT_HOME/lib.

2009/11/17 Adam Roundy <aroundy@...>

I set up bitronix in Tomcat 6 according to the instruction on this page : http://docs.codehaus.org/display/BTM/Tomcat13

I then configured spring like this, in the applicationContext.xml file :

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/dataSource"/>
</bean>

<bean id="btmTransactionManager" class= "org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/UserTransaction"/>
</bean>

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"
depends-on="btmTransactionManager">
<property name="transactionManager" ref="btmTransactionManager" />
<property name="userTransaction" ref="btmTransactionManager" />
</bean>

and I end up with this error:

org.springframework.beans.TypeMismatchException: Failed to convert property value of type [bitronix.tm.BitronixTransactionManager] to required type [javax.transaction.TransactionManager] for property 'transactionManager'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [bitronix.tm.BitronixTransactionManager] to required type [javax.transaction.TransactionManager] for property 'transactionManager': no matching editors or conversion strategy found

I have tried a few different configurations to get and insert the bitronix.tm.BitronixTransactionManager into the JtaTransactionManager bean, all with the same message that it can't covert from the bitronix type object to the javax type; which doesn't make any sense to me because the first implements the second.

What am I missing?

[CUT CUT]

Ludovic, thank you again about your response... Ok, I use BTM only for iBatis (r/w) and push on queue... for enque from Oracle AQ I use (4 now) simple connection e commit/rollback non JTA.

I am very busy by work, but I'm cutting out time to finish the guide for BTM and Oracle AQ to be made available to the community.

Thank you!

Renato,

The short answer to your questions is: the only way to have asynchronous message handling with BTM is to use a Spring DefaultMessageListenerContainer (http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/jms/listener/DefaultMessageListenerContainer.html) or equivalent.

In a nutshell, this is a class which starts a transaction, synchronously waits for a JMS message with a short timeout on the reception, rolls back the transaction if no message was read or send the message for processing to some worker when a message was read.

Polling the JMS container is the only portable way to get async messaging inside an XA transaction using only the JMS API. The onMessage() technique can't work because the JMS server would need a way to start a XA transaction after the message has been read. This technique was known as 'JMS Chapter 8' or 'ServerSessionPool stuff' but it proved to be unreliable, poorly specified and difficult to implement so this was dropped between J2EE 1.3 and J2EE 1.4 and replaced by JCA which offers this capability.

Re: Unable to register cleanup Synchronization with TransactionManager

2009-11-05T04:25:32Z

I found problem and solution.

Bitronix marks as readrollbackonly a transation after a time out.
So when I call getcurrentsession from Hibernate, hibernate tries to syncronize transaction and session and it calls the registerSynchronization bitronix's method, but this method lanch a exception as code below

if(status == 1)
throw new BitronixRollbackException("transaction has been marked as rollback only");

In my facade I add a little code like this:

if (getUserTransaction().getStatus() == Status.STATUS_MARKED_ROLLBACK) {
getUserTransaction().rollback();
getUserTransaction().begin();
}

and now all works fine.

I had difficult to find the solution becouse hibernate does't thow the bitronix exception but a own exception
like
throw new HibernateException( "Unable to register cleanup Synchronization with TransactionManager" );
instead
Thown t //where t is the Throwable hibernate exception

p.s. I use hibernate 3.3

Exactly!

I didn"t use the transaction-manager attribute in the Spring
Integration message-driven-channel-adapter element.
Well, for my defense I would say that Spring Integration reference is
not that clear about it.

Thanks for your help Ludovic, it's very valuable as usual.

Without the full stack trace it's hard to say what the exact cause is.

I'm guessing that this has to do with the DefaultMessageListenerContainer trying to read messages outside of a transaction context but I would need more details (ie: relevant parts of your spring config) to confirm.

Re: Oracle JMS AQ

2009-10-30T02:18:57Z

SOLVED!
Now I have jdbc/iBatis + jms/oracle + tomcat in BTM-JTA fashion!!! :)

The problem was in code where I have create xaconnection... if I call it directly (point 5 of my previus post) I obtain an unregister XAResource...

#################### WRONG WAY ##########################
XAConnection xaConnection = btmJCH.getXAConnection();
xaConnection.start(); // start connection
AQjmsXAConnection aQjmsXAConnection = (AQjmsXAConnection) xaConnection;
XATopicSession xaTopicSession = aQjmsXAConnection.createXATopicSession();
#################### WRONG WAY ##########################

I'll post my solution (the modified point 5 of my previous post), if you want, I can write it in a how-to/wiki article style for publish this experience in BTM wiki.... tell me...

point 1, 2, 3, 4 was correct and wasn't modified... the point 5 was correct in this way

5) #################### RIGHT WAY ##########################
Context initContext = new InitialContext();
PoolingConnectionFactory myConnectionFactory = (PoolingConnectionFactory) initContext.lookup("java:comp/env/jms/oracle");

UserTransaction ut = (UserTransaction) initContext.lookup("java:comp/UserTransaction");
ut.begin();

Connection connection = myConnectionFactory.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

Topic topic = session.createTopic(Configuration.getJmsOracleXmlMessageTopic());

DualSessionWrapper dualSessionWrapper = (DualSessionWrapper)session;
AQjmsXASession aQjmsXASession = (AQjmsXASession) dualSessionWrapper.getSession();

StringWriter stringWriter = ....; // contain my XML Payload....
XMLType xml = new XMLType(qjmsXASession.getDBConnection(), stringWriter.toString());
AdtMessage message = ((AQjmsXASession)xaTopicSession).createAdtMessage();
message.setAdtPayload(xml);

MessageProducer publisher = session.createProducer(topic);
publisher.send(message);

ut.commit();

// ut.rollback(); //if somethig was wrong........

Thanks Ludovic!!!!! Thanks BTM!

Re: Oracle JMS AQ

2009-10-29T16:37:03Z

Thanks for your replay Ludovic!

I decided to follow the first choice so I implemented XAConnectionFactory, configure it in resource loader propery file, bind it in context.xml (tomcat integration) and write some line of code in my utility class to get Pooling connection from jndi and create session and publisher..... at end of this post I'll publish my solution.

But I have encuntered a problem... I'think XAConnection that I retrive from pool isn't an enlisted resources... the BTM warning log is explicity when I try to ut.commit() a user transaction:

29-Oct-2009 23:45:19 bitronix.tm.twopc.Preparer prepare
WARNING: executing transaction with 0 enlisted resource

the only logical difference between JndiXAConnectionFactory and my OracleXATopicConnectionFactory is that mine solution implements XATopicConnectionFactory, beacuse I need a topic in my app.

In my numerous tests I have try to insert the correponding XAResource in transaction manager in this way:

BitronixTransactionManager btm = (BitronixTransactionManager) ut;
btm.getTransaction().enlistResource(xaTopicSession.getXAResource());

and btm throw
bitronix.tm.internal.BitronixSystemException: unknown XAResource oracle.jms.AQjmsXAResource@112bc7b, it does not belong to a registered resource

I don't know why this is not registered in btm... can you tell me something about it?

Follow what I did....

1) IMPLEMENTATION OF XATopicConnectionFactory
public class OracleXATopicConnectionFactory implements XATopicConnectionFactory {

private String driver;
private String url;
private String user;
private String pwd;

Re: Oracle JMS AQ

2009-10-28T11:40:40Z

Oracle AQ really is a special JMS implementation, to say the least.

You first need to get some queues created with the DBMS_AQJMS PL/SQL package. You then need some privileges:

* ENQUEUE rights on all queues you're going to send to
* DEQUEUE rights on all queuse you're going to receive from
* EXECUTE rights on DBMS_AQJMS
* EXECUTE rights on DBMS_AQIN

After that's done you're still facing a dilemma: Oracle provides a weird way to get a XAConnectionFactory, via a AQjmsFactory helper class' static method (see: http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b12023/oracle/jms/AQjmsFactory.html) and BTM unfortunately has no support for such an exotic mechanism. So you basically have two choices:

- Write your own XAConnectionFactory implementation, make it use AQjmsFactory and configure it in BTM. It shouldn't be very hard as there are only two methods to implement (http://www.j2ee.me/j2ee/1.4/docs/api/javax/jms/XAConnectionFactory.html) plus a few getters/setters for configurable data you'll need to call getXAQueueConnectionFactory(). Have a look at the source code of JndiXAConnectionFactory to get an example of how to do this: http://fisheye.codehaus.org/browse/btm/branches/1.3.3/src/bitronix/tm/resource/jms/JndiXAConnectionFactory.java?r=HEAD

- Wrap the non-XA AQjmsConnectionFactory (http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b12023/oracle/jms/AQjmsConnectionFactory.html)in a LrcXAConnectionFactory (see: http://docs.codehaus.org/display/BTM/LastResourceCommitJms13)

Let me know if that helps.

Hi all,
is possibile to integrate Oracle JMS AQ with BTM and Tomcat?

I made a lot of experimental configuration with resource loader, context.xml ecc... without success...

I'm bit confusing....

Has someone did it? An example or guideline?

Thanks all!

Hello,
I'm tring to integrate btm 1.3.3 with apache-tomcat-5.5.27. I follow the guide at http://docs.codehaus.org/display/BTM/Tomcat13 but I have thi error when Tomcat start:

27-Oct-2009 21:31:56 org.apache.tomcat.util.digester.Digester startElement

ecc...

The only thing that difference from guide is about Tomcat's lib: for m the guide refereds at common/lib so I put all required jars under common/lib....

The tomcat installation is fresh and running under ubuntu 9.04 and java version "1.6.0_16".

I saw in forum that more users have integrated btm in tomcat 5.5.27 successfull... I hope that some one can help me...

Thanks!

Re: Connection pooling

The performance hit of the test query usually isn't that high.

As an alternative if you know for sure the DB is restarted when there are no users you could set the minPoolSize to zero, make sure the maxIdleTime isn't too high and also make sure the pool is left untouched long enough for all connections to become inactive. The pool will then close them all and re-open them when activity starts over again.

2009/10/27 Gérald Quintana <gerald.quintana@...>

Thanks for your answer Ludovic,

At first, I imagined this solution. But I think it would be bad for
performances: I loose connections only once a day, and the test query
would be executed all day long (too many times). What's your
experience/opinion?

Then during the night, the application is not used anymore so I don't
understand why connections are kept opened.

Finally is there something (JMX MBean or other) to control (I mean
monitor opened connection, force closing) connection pools described
in resources.properties?

What can I do to evict them?

Regarding Spring and its dependencies it's quite the contrary: you need to specify a 'depends-on' attribute betwen the TM bean and the config bean or Spring won't know when to initialize the config as it's not injected in the TM.

You're right, the dependency is about instances returned by factory methods, not bitronix.tm.TransactionManagerServices itself.

so


<bean id="BitronixTransactionManager" factory-method="getTransactionManager"
