You could of course, use a combination of 1 & 2 using a stateful session
bean...
public MySessionBean implements SessionBean {
...
private UserTransaction utx=null;
public void methodA() {
utx = ctx.lookup("java:comp/env/UserTransaction");
utx.begin();
//writes to DB - omitted
}
public void methodB() {
//writes to DB...
if (someCondition)
utx.rollback();
}
public void methodC() {
utx.commit();
}
}
This would allow for user interaction in the middle of a transaction (in
contrast to before the tx)
