You need to specify the -Djava.awt.headless=trueparameter at startup time.
您需要-Djava.awt.headless=true在启动时指定该参数。
回答by grepit
This will fix it:
这将修复它：
/usr/bin/java -Djava.awt.headless=true $Your_program
回答by bebbo
Remove the DISPLAY variable
删除 DISPLAY 变量
unset DISPLAY
This helps in most cases (e.g. starting application servers or other java based tools) and avoids to modify all that many command lines.
这在大多数情况下都有帮助（例如启动应用程序服务器或其他基于 Java 的工具）并避免修改所有那么多命令行。
It can also be comfortable to add it to the .bash_profile for a dedicated app-server/tools user.
也可以很方便地将它添加到 .bash_profile 以供专用的 app-server/tools 用户使用。

the only way i got it to work was running the script with a template. e.g. sudo ./glassfish-3.1.2.2-unix.sh -s template
我让它工作的唯一方法是使用模板运行脚本。例如 sudo ./glassfish-3.1.2.2-unix.sh -s 模板
This installs Glassfish in Silent Mode. http://docs.oracle.com/cd/E18930_01/html/821-2427/ghmva.html
这将在静默模式下安装 Glassfish。http://docs.oracle.com/cd/E18930_01/html/821-2427/ghmva.html

If you see this error in Hudson, try to remove the .java directory from your home directory, it may work for you.
如果您在 Hudson 中看到此错误，请尝试从您的主目录中删除 .java 目录，它可能对您有用。

If you start application on a remote server while logged in by ssh then another way would be to start ssh with -xparameter or add ForwardX11 noin your /etc/ssh/ssh_config. In this case ssh will not create environment variable DISPLAY.
如果您在通过 ssh 登录时在远程服务器上启动应用程序，则另一种方法是使用-x参数启动 ssh或ForwardX11 no在您的/etc/ssh/ssh_config. 在这种情况下，ssh 不会创建环境变量 DISPLAY。
