Hi there Robert,
According to the EJB 1.1 spec, the setting of the transaction isolation level
is no longer a standard that has to be enforced by the EJB containter. As
several database vendors had it different ways of providing transaction
isolation, it was decided to delegate that responsability to the JDBC drivers.
In EJB 1.0, the vendors provided ways of setting the transaction isolation,
but not in EJB 1.1.
Based on this, we cannot say that Orion does not conform to the J2EE spec. If
you take a close look at Sun's J2EE Reference Implementation, you'll see that
their RI does not provide a way to set the transaction isolation level.
You still can set the transaction demarcation for each method, and if you
want, to use the transaction services provided by the server to
programmaticaly define your own transaction demarcation.
Hope this helps,
F�bio
