在远程桌面上使用Javafx，而无需显示

发布于 2025-02-10 05:12:04 字数 1814 浏览 0 评论 0原文

我目前正在本地桌面上构建Javafx，并且将所有渲染图表保存为快照并保存它们。现在，我需要在没有UI和显示的远程云桌面上运行我的Javafx程序。因此，现在我遇到了此错误：引起：Java.lang.unsupportedoperationException：无法打开显示。

有没有办法解决这个问题，我仍然可以在远程云桌面上没有显示的情况下获取快照吗？

我尝试添加-dglass.platform = monocle -dmonocle.platform = headless -dprism.order = sw在我的远程桌面上运行时，但是错误消息是相同的。我是否需要安装或添加任何依赖性单镜工作？

I'm currently building javafx on my local desktop, and I save all rendered charts as snapshot and save them. Now I'm need to run my javafx program on remote cloud desktop that does not have UI and display. So now I'm encountering this error: Caused by: java.lang.UnsupportedOperationException: Unable to open DISPLAY.

Is there a way around this, can I still get the snapshot without having a display on my remote cloud desktop?

I tried adding -Dglass.platform=Monocle -Dmonocle.platform=Headless -Dprism.order=sw when running on my remote desktop, but the error message is the same. Do I need to install or add any dependency for Monocle to work?
