|
---------------------------------
|
|
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
