---|
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 |
---|
