Assemble EJB 2.1 enterprise beans

Subtopics

• Assemble 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 containing container-managed persistence beans, we can prevent certain types of database-related exceptions from occurring during application run time. Using sequence grouping, we 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, we can prevent certain types of database-related exceptions during the run time of custom EJB application. Specify in each group the order in which the beans update your relational database tables.
