I was under the impression that transaction isolation settings, such as TRANSACTION_REPEATABLE_READ, TRANSACTION_SERIALIZABLE etc. were set on each bean. I know you do this in websphere.
I have just read that apparently in ejb 1.1 this has been done away with and can only be set in a resource manager (JDBC) or vendor specific deployment tool. The isolation is not set in the depolyment descriptor anymore.
Is this the case? Are vendors such as Weblogic still letting you set the isolation level on each bean?
