如何在全球范围内对OS X的Java系统属性？ [英] How to set java system properties globally on OS X?

问题描述

我需要一个系统级的方式向 java.awt.headless 属性设置为真 所有Java调用的。也就是说，使用 -Djava.awt.headless = TRUE 是不是一种选择，由于Java是从地方调用我没有访问（例如从另一个工具用Java / C的/ etc。）

I need a system level way to set the java.awt.headless property to true for all java invocations. That is, using -Djava.awt.headless=true is not an option, since java is being invoked from places I don't have access to (e.g. from within another tool written in Java/C/etc.)

我用了一堆用Java编写的（特别是Adobe的空气ADT）的工具，依赖于AWT类。当我在控制台上运行这些工具，他们很好地工作。但是，当我从一个SSH会话未能以 java.lang.InternalError运行它们：无法连接到窗口服务器 - 没有足够的权限。周围的Googling我发现，设置java.awt.headless为true，将会解决这个问题。这不，那是因为ADT本身滋生孩子的Java程序的的没有的 -Djava.awt.headless = TRUE

I'm using a bunch of tools written in Java (specifically Adobe's Air ADT) that rely on AWT classes. When I run these tools on the console they work fine. But when I run them from an SSH session they fail with java.lang.InternalError: Can't connect to window server - not enough permissions. Googling around I found that setting java.awt.headless to true will fix the problem. It doesn't, and that's because ADT itself spawns children Java processes without -Djava.awt.headless=true.

有没有系统级的方法，以确保此属性设置时的Java调用？也许有些系统AWT属性文件或等效？

Is there any system-level way to ensure this property is set whenever Java is invoked? Maybe some system awt property file or equivalent?

最坏的情况，我可以尝试更换的/ usr / bin中/ java的用shell脚本，会将此参数$ @，但我希望能避免这种情况。 （更新：只是为了确保我的理论是正确的，试过这个shell脚本黑客，它不会解决问题只是希望有一个更清洁的解决方案。）

Worst case scenario I could try replacing /usr/bin/java with a shell script that adds this argument to "$@" but I'm hoping to avoid that. (Update: Just to ensure my theory is right, tried this shell script hack and it does solve the problem. Just hoping for a cleaner solution)

推荐答案

使用 _JAVA_OPTIONS ，而不是 JAVA_OPTS 的。 _JAVA_OPTIONS 将得到回升时，会自动运行java。

Use _JAVA_OPTIONS instead of JAVA_OPTS. _JAVA_OPTIONS will get picked up automatically when you run java.

export _JAVA_OPTIONS=-Djava.awt.headless=true
adt ... 

我知道这是真的在OS X 这表明，这可能工作在Windows和Linux，以及。

I know this is true on OS X. This indicates that this may work on Windows and Linux, as well.
