for your J2EE implementations, which helps ensure consistency.
asynchronous requests, and Entity
EJB
s can handle various data and data ser-
vices with no need to run a specific database application. As an example, you'll
create two
EJB
s: a
CMP
Entity bean (an Entity bean to quickly restore the data-
base data without manual
SQL
coding) and a Session bean.
You can create
EJB
s using the context menu in the
Project
view. Right-click an
EJB
module there or press
Alt+Insert
, and select a necessary item under the
New
submenu. Now, do the following:
Select a bean type (
CMP
Entity or Session).

In the resulting dialog, shown in figure 11.11, specify the bean name,
package, bean class, and interfaces (local and remote).

Fo r
CMP
beans, set the primary key class and
CMP
version.

Editing EJB deployment descriptors
Like web modules,
EJB
modules and
EJB
s have deployment descriptors. Deploy-
ment descriptors are essential for the deployment process success. Without the
properly configured deployment descriptor, an application server doesn't know
what to do with files you provide. The deployment descriptors are automatically
created by
IDEA
and shown in a graphic way. For instance, suppose you need to
add security roles, change classes/interfaces for
EJB
s, and so on. Changes you
