For more detailed information about EJB access beans, see Access beans and related topics.
There are four types of access beans:
Java bean wrappers and copy helpers are part of the original access bean design that was used in VisualAge® for Java. Both types of access bean are also supported in the workbench. Although rowset access beans were also part of the original design in VisualAge for Java, they are not supported in the workbench.
EJB factory and data class access beans, by comparison, are part of a new access bean design that is used in the workbench.
If you have an existing application that employs access beans that
were created in VisualAge for Java, you can use the access bean
wizards to create or edit Java bean
wrapper or copy helper access beans. However, if you are developing
a new application, it is recommended that you create only data class
access beans, which employ the new design. EJB factories are automatically
created by the Create an Access Bean wizard regardless of whether
you choose to create a data class, Java bean
wrapper, or copy helper. For this reason, EJB factories do not appear
on the selection page of the Create an Access Bean wizard, where you
specify the type of access bean that you want to create. For information
about creating access beans, see Creating EJB access
beans.
