jnlp 文件提示 mac 下载 JRE，但它已经安装 (Java 1.6.0_37) Mac OSX 10.7.5 [英] jnlp file is prompting mac to download JRE, but its already installed (Java 1.6.0_37) Mac OSX 10.7.5

问题描述

我什至不知道在这里发什么，除了电脑上的终端说:

I don't even really know what to post in here except for the fact that the terminal on the computer says:

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

但是由于某种原因，当我运行 JNLP 文件时，会弹出一个提示，说要打开此 Web 启动应用程序，我需要下载 Java 运行时环境.我已经这样做了.它最初安装的是 Java 7，经过一些研究，我发现这个 jnlp 文件在安装 Java 7 时无法打开.所以我回去删除了 Java 7，现在这正在发生.

but for some reason when i run the JNLP file a prompt pops up saying that to open this web start application I need to download the Java Runtime Environment. Which I already did. It originally installed Java 7, and after doing some research I discovered that this jnlp file won't open with Java 7 installed. So I went back and removed Java 7, and now this is happening.

如果我打开 Java Preferences 窗口，我可以看到确实安装了 Java SE 6.我只是不知道该怎么办.

If I open the Java Preferences window, I can see that Java SE 6 is indeed installed. I just have no idea what to do.

终端说

No Java runtime present, requesting install. Unable to locate a Java Runtime to invoke.

当我输入

javaws /(path).jnlp

我也跑了 janela，得到了这份报告:

Also I ran janela, and got this report:

对不起，我知道很多，但我什至不知道什么是重要的，什么是不重要的.希望这会有所帮助.

I'm sorry i know its a lot, but I don't even know what is important and what isn't. Hope this helps.

推荐答案

如果您安装了 Oracle Java 7，您可以使用以下命令运行 jnlp 文件:

If you installed Oracle Java 7, you can run jnlp files with:

'/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaws' file.jnlp

如果需要，您还可以将 /usr/bin/javaws 文件替换为 /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin 的符号链接/javaws.

If you would want, you can also replace /usr/bin/javaws file with a symlink to /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/javaws.
