Migrating Enterprise JavaBeans projects
(EJB 1.1 to EJB 2.x)
Migrating an EJB project from the EJB 1.1 to EJB 2x specification
level is described in this section.
About this task
Migrating an EJB project from EJB 1.1 to EJB 2.x involves
the migration of container-managed persistence (CMP) entity beans.
There
have been no changes in entity beans between J2EE 1.3 and J2EE 1.4
specification level. Migrating CMP entity beans from the EJB 1.1 to
EJB 2.1 specification level is accomplished the same way as migrating
a CMP entity bean from EJB 1.1 to EJB 2.0. Migrating container-managed
entity beans from EJB 1.1 to EJB 2.x specification level requires
the following steps:
Migrating EJB references for EJB 1.1 relationships
When EJB 1.1 relationships were created, EJB references
were created to the Remote Client view. During the EJB 1.1 project
migration using the J2EE Migration wizard, these EJB remote references
for the EJB 1.1 relationships are removed and replaced with EJB local
references. Local references for user-defined EJB references must
be recreated manually.
Merge of method elements during project structure migration
During the project structure migration using the J2EE Migration
wizard, the method elements (that include security identity, container
transaction, method permissions, access intent, and isolation levels)
of the same type for all the beans are merged to make them logically
grouped.
