Example: Creating beans with a visual bean builder

This example uses the IBM^® VisualAge^® for Java™ Enterprise Edition V2.0 Composition Editor, but other visual bean builders are similar. This example creates an applet for a button that, when pressed, runs a command on the iSeries™ server.

• Drag-and-drop a Button on the applet. (The Button can be found in the bean builder on the left side of the Visual Composition tab in Figure 1.)
• Drop a CommandCall bean and an AS400 bean outside the applet. (The beans can be found in the bean builder on the left side of the Visual Composition tab in Figure 1.)

• Edit the bean properties. (To edit, select the bean and then right-click to display a window, which has Properties as an option.)
  • Change the label of the Button to Run command, as shown in Figure 2.

  • Change the system name of the AS400 bean to TestSys
  • Change the user ID of the AS400 bean to TestUser, as shown in Figure 3.

  • Change the command of the CommandCall bean to SNDMSG MSG('Testing') TOUSR('TESTUSER'), as shown in Figure 4.

• Connect the AS400 bean to the CommandCall bean. The method you use to do this varies between bean builders. For this example, do the following:
  • Select the CommandCall bean and then click the right mouse button
  • Select Connect
  • Select Connectable Features
  • Select system from the list of features as shown in Figure 5.
  • Select the AS400 bean
  • Select this from the pop-up menu that appears over the AS400 bean

• Connect the button to the CommandCall bean.
  • Select the Button bean and then click the right mouse button
  • Select Connect
  • Select actionPerformed
  • Select the CommandCall bean
  • Select Connectable Features from the pop-up menu that appears
  • Select run() from the list of methods as shown in Figure 6.

When you are finished, the VisualAge Visual Composition Editor window might look like Figure 7.
