Using the command bean creation wizard, you can create a command
bean to invoke certain EIS operations.
Creating a command bean allows you to encapsulate the execution of a specific operation within the EIS. 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's implementation is generated, and it uses the method-level annotation tag @j2c.command to specify the command bean class that will be generated for a given method.
