Christian, tank you very much for your answers. Now everything is clearer.
Since every call to a SFSB method is performed into a different database transaction, my final question is how can I manage transactions so that two or more SFSB methods are executed into the same transaction ? What I am trying to do is very simple: 1) I start an input form for the Entity Bean A 2) From the input form I open a pop up window in which I can choose items from EB B or I can create new items 3) When I close the pop up the A form is update (so that the back entity bean) 4) If I cancel the operation I would like that the B items would not be saved to the database I though that a long-running conversation would be the solution. It is not. Now, I still think that I have to execute A and B methods into a single (user) transaction but where I can open and commit it ? Any other solution that doesn't involve an explicit transaction management ? Regards Fab.
