Transaction Manager JBOSS & HornetQ

sergiu_pienar Oct 15, 2010 8:26 AM

Hi ,

Let's assume we have the following situation :

JBoss is configured to work alongside HornetQ .When an insert/update/delete is sent to the database

HornetQ also sends a message to the client.The question is : if that insert/update/delete fails thus being rollbacked

can HornetQ be configured in such a manner that the message HornetQ sent is also rolledback -preventing it to

reach the client , if the main transaction failed.

Clearly put , either both (insert/update/delete and HornetQ message) are commited either both are rolledback.

Thx.

yes.. you're basically asking if HornetQ is XA compliant.

Also, look at the hornetq/ee/recovery-xa example

Thx ,
Additional question : is there any setting to be made for this XA compliancy to be enabled ?

Sorry for bugging you.

If you're using MDBs.. the JCA adapter will do it automatically for you.

If you are doing the JCA Adapter from jms-xa, it will also be done automatically.

^^ look at the application's server documentation for how to do it ^^

If you're using regular Connection Factories, you should declare them as XA and enlist them on the transaction manager (at that point you should refer to the TM's documentation on how to enlist resources).

There are a few examples on mdbs doing this. Look at the recovery example.

Well , it all seems to be configured properly but i can't make it work.
I have an EJB test client ; if this works well , the message gets processed , but if in the EJB client i throw an EJBException the message will still reach the client.How can this be fixed ?

Thk u.
