Using the command bean creation wizard, you can create
a command bean to invoke certain enterprise information system operations.
Command beans encapsulate the execution of a specific operation
within the enterprise information system. Input and output parameters
are established through get and set methods, and the operation is
executed when the execute() method of the bean
is called.
Command bean topology
Command beans are created
after the J2C bean implementation is generated. Command beans use
the method-level annotation tag,
@j2c.command, to
specify the command bean class that is generated for a given method.
