Here is how i would do it:
The method in your session bean has tx attribute TX_REQUIRED and the create
method in all your entiy beans has tx attribute TX_MANDATORY. This way a tx will
be started when the method in session bean is started and will be commited if
all the entity beans has been correctly created, otherwise every work is rolled
back. No more coding of yourself, the container will manage it (at least the one
i'm using :-)
