Assembling EJB 2.1 enterprise beans
- 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 EJB modules based on the EJB 2.x and earlier specifications.
- Sequence grouping for container-managed persistence in assembled EJB modules
After assembling an 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.
- Set 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 EJB application. Specify in each group the order in which the beans update your relational database tables.
