HeadlessException - X11 required for addFromHtml on Slides Level on Linux

Aspose.Slides Product Family
1

Hello there,

maybe there is a bug on the following function:

Presentation pres = new Presentation();
pres.getSlides().addFromHtml(“test”);

Please note this happens only on remote linux server environments without X11 installed nor forwarded via ssh session. The -Djava.awt.headless=true is causing another error - but maybe it can be used for testing.


Caused by: java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.

hello there,


you can just set
System.setProperty(“java.awt.headless”, “true”);

it would not give the x11 error but the same headless exception location.

Hi Rennicke,

Thank you for the details.

I tested your issue on my Linux environment and I am unable to reproduce the issue with JDK 1.6.0. I will further test the issue with 1.7.0_60 to make sure if it works fine with the version you are using. I will update you regarding the test results soon.

Thanks & Regards,
