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
|
