64 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
80 ID #18747: http://www.macromedia.com/go/tn_18747
