java - 抑制 GUI？

Question

我正在尝试运行专为 Vuze 设计的插件使用Java。为此，我使用这样的命令:

/home/x/jre1.6.0_14/bin/java -Dazureus.config.path=/home/x/plugin_directory -Dfile.encoding=ANSI_X3.4-1968 -classpath /home/x/P/lib/swtgraphics2d.jar:/home/x/P/lib/Azureus2.jar:/home/x/P/lib/swt.jar org.gudy.azureus2.ui.swt.Main

问题在于启动失败并出现错误:

changeLocale: *Default Language* != English (United States). Searching without country..
changeLocale: Searching for language English in *any* country..
changeLocale: no message properties for Locale 'English (United States)' (en_US), using 'English (default)'

我确信这是在发生，因为我正在终端上运行该程序。有没有办法抑制 GUI 或让程序认为 GUI 已成功生成？有什么建议吗？

Answer 1

运行前尝试在终端中设置 DISPLAY 环境变量:

export DISPLAY=<IP address>:0.0

您的主机地址(或其主机名)在哪里。

如果您根本不在 GUI 下运行，则必须运行虚拟帧缓冲区。 Xvfb 是我过去用过的那个。只需确保它已安装:sudo apt-get xvfb 然后在运行您的应用程序之前执行以下命令:

Xvfb :1 -ac -screen 0 1024x768x8 &

export DISPLAY=:1 

然后运行应用程序..
