指向JAVA_HOME定义的JRE的Java AppBundler应用程序 [英] Java AppBundler application pointing to JRE defined by JAVA_HOME

问题描述

我一直在使用 Java Application Bundler 将Java应用程序打包为.app。如果我在.app包中包装JRE7，我已设法运行该应用程序。
是否可以配置.app（在Info.plist中）指向JAVA_HOME环境变量定义的JRE？
如果我这样做，我得到无法加载Java运行时环境！我试图以不同的方式配置JAVA_HOME，但没有成功！

I have been using Java Application Bundler to pack a Java application as .app. I have managed to run the application if I pack the JRE7 inside of the .app bundle. Is it possible to configure .app (in Info.plist) to point to the JRE defined by JAVA_HOME environment variable? If I do that, I am getting "Unable to load Java Runtime Environment"! I have tried to configure the JAVA_HOME in different ways, but with no success!

任何人都可以提供任何帮助或建议吗？

Can anyone provide any help or suggestion?

推荐答案

appbundler 应用程序可以使用应用程序包中的嵌入式Java 7 JRE，也可以使用<7>中安装的Java 7 JRE code> / Library / Internet Plug-Ins / JavaAppletPlugin.plugin / Contents / Home （与Web浏览器插件使用的相同）。他们不能使用 / Library / Java / JavaVirtualMachines 下安装的 JDK （或其他任何地方），他们绝对不能使用Java 6.

appbundler applications can use either an embedded Java 7 JRE inside the app bundle, or the Java 7 JRE installed in /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home (the same one used by the web browser plugin). They can't use a JDK installed under /Library/Java/JavaVirtualMachines (or anywhere else, for that matter) and they definitely can't use Java 6.

而是手动构建bundle，主可执行文件是一个shell脚本，它运行 JAVA_HOME java 命令行工具>（如果未设置 JAVA_HOME ，可能会回退到 / Library / Internet Plug-Ins JRE）。这样的脚本将能够支持Java 6和7。

What you can do, however, is not use appbundler and instead build the bundle by hand, with the main executable being a shell script that runs the java command line tool from JAVA_HOME (maybe falling back to the /Library/Internet Plug-Ins JRE if JAVA_HOME is not set). Such a script will be able to support both Java 6 and 7.

您可以使用类似这样的内容 YourApp.app/Contents/MacOS/ YourApp ：

You would use something like this as YourApp.app/Contents/MacOS/YourApp:

#!/bin/sh

PRG=$0

while [ -h "$PRG" ]; do
    ls=`ls -ld "$PRG"`
    link=`expr "$ls" : '^.*-> \(.*\)$' 2>/dev/null`
    if expr "$link" : '^/' 2> /dev/null >/dev/null; then
        PRG="$link"
    else
        PRG="`dirname "$PRG"`/$link"
    fi
done

progdir=`dirname "$PRG"`

if [ -n "$JAVA_HOME" ]; then
  JAVACMD="$JAVA_HOME/bin/java"
elif [ -x /usr/libexec/java_home ]; then
  JAVACMD="`/usr/libexec/java_home`/bin/java"
else
  JAVACMD="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java"
fi

exec "$JAVACMD" -classpath "$progdir/../Resources/Jars/*" \
       -Dapple.laf.useScreenMenuBar=true \
       my.pkg.MainClass

然后将应用程序的JAR文件放在<$ c中$ c> YourApp.app/Contents/Resources/Jars ， YourApp.app/Contents/Resources/icon.icns 中的图标，以及以下 YourApp.app/Contents/Info.plist ：

Then put your application's JAR files in YourApp.app/Contents/Resources/Jars, the icon in YourApp.app/Contents/Resources/icon.icns, and the following in YourApp.app/Contents/Info.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>CFBundleDevelopmentRegion</key>
        <string>English</string>
        <key>CFBundleExecutable</key>
        <string>YourApp</string><!-- relative to Contents/MacOS -->
        <key>CFBundleGetInfoString</key>
        <string>My clever application</string>
        <key>CFBundleIconFile</key>
        <string>icon.icns</string><!-- relative to Contents/Resources -->
        <key>CFBundleInfoDictionaryVersion</key>
        <string>8.0</string>
        <key>CFBundleName</key>
        <string>YourApp</string>
        <key>CFBundlePackageType</key>
        <string>APPL</string>
        <key>CFBundleSignature</key>
        <string>????</string>
        <key>CFBundleVersion</key>
        <string>8.0</string>
</dict>
</plist>

参见 GATE Developer launcher 获取完整的详细信息，但请注意，这是一个稍微复杂的情况，因为 .app 脚本委托给另一个脚本，该脚本又从 .app 包之外的位置加载JAR文件。但原则仍然相同。

See the GATE Developer launcher for full details, though note that this is a slightly more convoluted case as the .app script delegates to another script, which in turn loads the JAR files from a location that is outside the .app bundle. The principle remains the same however.
