Dear Philip,

thanks for the help.
The missing trans-attribute is due to a 'cutpaste' error writing
the letter. I'm very interessed to see your working code.

thanks a lot.

Christian

 Hi Christian,
 Frankly we have the same problem, trying to access the entity bean
 through a session bean and not being able to rollback. However
 rollback is working perfectly fine in stateful/stateless session bean.
 
 One thing which I noticed in your xml file is that you have not given
 the tranas-attribute 'Required'. You have to do that in order to get
 at least the stateless or stateful beans to work on transactions. E.g.
 do two sql 'inserts' in one session bean in one method and if one
 fails throw EJBException and the rollback happens.
 
 But in the case of an entity bean being accessed by a session bean, if
 the entity throws an EJBException in the ejbStore() that is not being
 caught by the session bean and so the rollback does not occur.
 
 If you want the code for the session beans working with rollback, I
 can send it to you. I have to thank Mr Rob Lapenese for that bit of
 help.
 
 Kind Regards
 Aby Philip
 
 

Transaction problems

[Christian Bagnoli]

Hi,

we're implementing an entity bean with transactional (container managed)
methods. This bean is accessed by
a session statefull bean. We have transactional problem when a method fails
(that is throws an EJBException) because orion doesn't rollback the
transaction.
Does anybody figure out how to make orion rollback the transaction?
We have also tried with a session stateless/stateful having the same problem
.
Also implementing the SessionSycronization interface doesn't trap the
transaction
boundaries.

Our data-source.xml is:

data-source
  class=com.evermind.sql.DriverManagerDataSource
  name=SetmoveDS
  location=jdbc/SetmoveDS
  xa-location=jdbc/xa/MySetmoveDS
  ejb-location=jdbc/myEJBDS
  connection-driver=oracle.jdbc.OracleDriver
  username=test
  password=test
  url=jdbc:oracle:thin:test/test@testsun:1521:test
  inactivity-timeout=30
 /

we use orion 1.5.2.

the ejb-jar.xml is:
