Why and when to perform this task
Support for Version 2.0 of the Enterprise JavaBeans (EJB) specification is new for Version 5 of this product. Migration of enterprise beans deployed in Version 4.0.x of this product is not generally necessary; Version 1.1 of the EJB specification is still supported. Follow these steps as appropriate for your application deployment.Steps for this task
Note: The EJB Version 2.0 specification mandates that prior to the EJB container's executing a findByMethod query, the state of all enterprise beans enlisted in the current transaction be synchronized with the persistent store. (This is so the query is performed against current data.) If Version 1.1 beans are reassembled into an EJB 2.0-compliant module, the EJB container synchronizes the state of Version 1.1 beans as well as that of Version 2.0 beans. As a result, you might notice some change in application behavior even though the application code for the Version 1.1 beans has not been changed.
