message queue. The <strong>MessageQueue</strong> object of the IBM<sup>®</sup> Toolbox for Java™ is used for this task. When the message
|

|

queue object is constructed, the parameters are the AS400 object and the message
|

|
|
queue name. The AS400 object indicates which server contains the resource,

|
|
and the message queue name identifies which message queue on the server.

In this case, a constant is used, which tells the message queue object to

access the queue of the signed-on user.</li>
