[EJB2.1 pp 378] "If there is also a container-transaction element that 
uses Style 1 element for the same bean, the value specified by the Style 
2 element takes precedence." And similarly for Style 3.

So your 3rd case, which is Style 2, overrides the first two which are 
both Style 1.

Or so I read it :-)
