Assembling EJB 2.x modules
An enterprise bean is a Java component
that can be combined with other resources to create Java EE applications. This topic describes assembling
Enterprise JavaBeans (EJB)
modules based on the EJB 2.x and earlier specifications.
Sequence grouping for container-managed persistence in assembled EJB modules
After assembling an Enterprise JavaBeans (EJB) module that contains container-managed
persistence (CMP) beans, you can prevent certain types of database-related
exceptions from occurring during application run time. Using sequence
grouping, you can specify the order in which entity beans update
relational database tables.
Setting the run time for CMP sequence groups
By designating container managed persistence (CMP) sequence
groups for entity beans, you can prevent certain types of database-related
exceptions during the run time of your Enterprise JavaBeans (EJB)
application. Specify in each group the order in which the beans update
your relational database tables.
