The Verification Code cannot be displayed, and an exception occurs on the server: cocould not initialize class sun. AWT. x11graphicsenvironment

Exception information:

Caused by: Java. Lang. noclassdeffounderror: cocould not initialize class sun. AWT. x11graphicsenvironment

Caused by: Java. Lang. internalerror: Can't connect to X11 window server using 'localhost: 10.0 'as the value of the display variable.

Website verification codes are essential! In fact, I am using Java SWT classes or methods. It works normally in the Windows system development, but it needs to be deployed to the Linux operating system, especially the X11 without a graphical interface installed, there will be no support.

Sh file under the bin directory of Tomcat installation directory:

-Djava. AWT. Headless = true \

Similar to this:
