        SPECIAL NOTE FOR HEADLESS SYSTEMS
65
 
        ---------------------------------
66
 
        If you get a "cannot connect to X11 server" when running certain
67
 
        parts of this component under Bluedragon (Linux), you must
68
 
        add "-Djava.awt.headless=true" to the java startup line in
69
 
        <bluedragon>/bin/StartBluedragon.sh.  This isssue is discussed
70
 
        in the Bluedragon Installation Guide section 3.8.1 for
71
 
        Bluedragon 6.2.1.
72
 
 
73
 
        Bluedragon may also report a ClassNotFound exception when trying
74
 
        to instantiate the java.awt.image.BufferedImage class.  This is
75
 
        most likely the same issue.
76
 
 
77
 
        If you get "This graphics environment can be used only in the
78
 
        software emulation mode" when calling certain parts of this
79
 
        component under Coldfusion MX, you should refer to Technote
