RE: AWT on AS400 Missing?

[Fred Newberry <fnewberry@xxxxxxxxxx>]

Don -
  The AS/400 does not have graphical devices so the AS/400 JVM has a RAWT
(Remote Abstract Windows Toolkit) that it invokes whenever there is a need
to do Graphical display work, or in fact even if there is only a need us any
piece of AWT that does not display on glass.
You will need to research and use the RAWT classes on a PC that is connected
via IP to the AS/400.  You will have to set the RmtAwtServer system property
to point the AS/400 JVM to the device to display the frame on.   This device
can be your PC.

Subject: AWT on AS400 Missing?



I am attempting to run a Java program that extends Frame.  It works on
Visual Age, but I get the following error when I run it on the AS400.
Anyone know why?  The error is:
        java.awt.AWTError: Toolkit not found: com.ibm.rawt.client.CToolkit

              java/awt/Toolkit.getDefaultToolkit()Ljava/awt/Toolkit;+51
(Toolkit.java:396)           
              java/awt/Frame.addNotify()V+14 (Frame.java:203)

              java/awt/Window.pack()V+27 (Window.java:123)

              testFrame.<init>()V+151 (testFrame.java:30)

              testFrame.main([Ljava/lang/String;)V+1 (testFrame.java:36)

        $


It seems to be loading AWT properly.  I used -verbose to display the
following loaded objects:
        Loading class java/awt/Frame.class from
/QIBM/ProdData/Java400/jdk117/lib/classes.zip                      
        Loading class java/awt/Window.class from

        Loading class java/awt/Container.class from

        Loading class java/awt/image/ImageObserver.class from
/QIBM/ProdData/Java400/jdk117/lib/classes.zip        

Note:  this is a subset...there a hundred or so.

My export in .profile is:
        export -s
