Some of the libraries require font and graphics support

If any user cannot export any dictionary and in TermWeb logs you see following error:

Caused by: com.nescit.BaseException: java.lang.NullPointerException at com.nescit.term.extern.ExportRunner.run(ExportRunner.java:40) at java.lang.Thread.run(Thread.java:750) Caused by: java.lang.NullPointerException at sun.awt.FontConfiguration.getVersion(FontConfiguration.java:1264) at sun.awt.FontConfiguration.readFontConfigFile(FontConfiguration.java:219) at sun.awt.FontConfiguration.init(FontConfiguration.java:107) at sun.awt.X11FontManager.createFontConfiguration(X11FontManager.java:774) at sun.font.SunFontManager$2.run(SunFontManager.java:441) at java.security.AccessController.doPrivileged(Native Method) at

Then it means your server doesn’t have installed X11 Window system.

 Solution

You need to find instructions for your Linux distribution how to install X11/xorg server.

  1. For example for distributions with YUM as package manager you need to run following command:

    sudo yum install xorg openbox

  2. Restart Tomcat with TermWeb.

 

Probably you may need to restart operating system too to apply all changes.
