基本上，问题是Java桌面集成在Linux上无法很好地工作。
它旨在与Windows配合使用。某些东西可以在其他系统上运行，但是没有人真正关心为这些系统添加适当的支持。即使安装了必需的“ gnome库”，结果也将很差。
前段时间我遇到了同样的问题，并提出了以下课程。
通过使用 特定 于 系统的命令 可以实现该目标：
KDE: kde-openGNOME: gnome-openAny X-server system: xdg-openMAC: openWindows: explorer
如果这些都不起作用，它将尝试Java Desktop提供的实现。
由于此操作通常会失败，因此将其作为最后的尝试。
DesktopApi类
此类提供静态方法
open，
browse和
edit。
经过测试，可以在Linux（Kde和Gnome），Windows和Mac上运行。
如果您使用它，请给我信誉。
