For further investigation, can you please try if export to PNG format is working?

 

Let me know the results.

 

Thanks

Please note the following findings:

 

 

In Unix/Linux/Solaris, there might be a problem while using java Graphics

package. ( as in the case of FusionCharts server-side exporter )

 

So when using FusionCharts for JSP export handler, you might run into the

following exceptions:

 

SYMPTOMS

 

EXTERNALINTERFACE: Could not initialize class sun.awt.X11GraphicsEnvironment

java.lang.Class.forName0(Native Method)

java.lang.Class.forName(Class.java: )

java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment

. )

java.awt.image.BufferedImage.createGraphics(BufferedImage.java: )

 

OR

 

java.lang.NoClassDefFoundError

at java.lang.Class.forName0(Native Method)

at java.lang.Class.forName(Class.java )

at

java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(GraphicsEnvironment

.java )

at java.awt.image.BufferedImage.createGraphics(BufferedImage.java )

 

OR

 

java.lang.InternalError: Can't connect to X11 window server using ...

 

----

 

CAUSE

 

 

Most versions of the Java.AWT library on Unix/Linux/Solaris require a

functioning X server. The X server and the DISPLAY environment variable are

not correctly set. X server is not installed in the machine.

 

SOLUTION

 

The best solution is to run Java in headless mode.

 

This can be done by adding

 

-Djava.awt.headless=true

to server options. ( >= jdk 1.4.2 )

 

The other solutions involve installing a library like PJA library or a X

server emulator.
